Water Conservation for Michigan – Why?

The Michigan Association of Planners is big on water conservation, joining several environmental groups to demand legislation requiring water conservation:

POLICY 4. Water Conservation: The Michigan Association of Planning supports state legislation requiring water conservation for public, and private users.

Among the classic legislation passed so far are laws requiring low flush toilets, and prohibiting high-volume shower heads as in this Seinfeld episode. I suppose I should go along: I’m running for water commissioner, and consider myself a conservationist. The problem is, I can’t see a good argument for these laws for most people here in Oakland County, or in neighboring Macomb and Wayne Counties. The water can’t run out because most users take it from the river and return it to the river, cleaned after it’s used; it’s all recycled.

The map above shows the clean water system for south-east Michigan. The high-population areas, the ones that are colored in the map, get their water from the Detroit River or from Lake Huron. It’s cleaned, pumped, and carried to your home along the pipes shown. Then after you’ve used the water, it travels back along another set of pipes to the water treatment plant and into the Detroit River.

When the system is working well, the water we return to the Detroit River is cleaner than the water we took in. So why legislate against personal use? If a customer wants to enjoy a good shower, and is willing to pay for the water at 1.5¢ per gallon, who cares how much water that customer uses? I can understand education efforts, sort-of, but find it hard to push legislation like we have against a high-volume shower head. We can not run out, and the more you use, the less everyone pays per gallon. A great shower head is a great gift idea, in my opinion.

The water department does not always work well, by the way, and these problems should be solved by legislation. We give away, for $200/year, high value clean water to Nestle company and then buy it back for $100,000,000. That’s a problem. Non-flushable toilet wipes are marketed as flushable; this causes sewer blockades. Our combined sewers regularly dump contaminated water into our rivers, lakes, and basements. These problems can be solved with legislation and engineering. It’s these problems that I’m running to solve.

Robert Buxbaum, January 6, 2019. If you want to save water, either to save the earth, or because you are cheep, here are some conservation ideas that make sense (to me).

We don’t need no stinking primary clarifier

Virtually every sewage plant of Oakland County uses the activated sludge process, shown in the layout below. Raw sewage comes in, and goes through physical separation — screening, grit removal, and a first clarifier – settling tank before moving to the activated sludge oxidation reactor. The 1st clarifier, shown at left below, removes about half of the incoming organics, but it often stinks and sometimes it “pops” bubbles of fart. This is usually during periods of low flow, like at night. When the flow is slow, it arrives at the plant as a rotting smelly mess; it’s often hard to keep the bubbles of smell down.

The smell is much improved in the oxidation reactor, analyzed here, and in the 2nd clarifier, shown above at right. Following that is a filter, an ultraviolet cleanup stage, and the liquids are discharged to a local river. In Oakland county, the solids from the two clarifiers are hauled off to a farm, or buried in a landfill. Burial in a landfill is a costly waste, as I discuss here. The throughputs for most of these treatment plants is only about 2-3 million gallons of sewage per day. But Oakland county can produce 500 million gallons of sewage per day. The majority of this goes to Detroit for treatment, and sometimes the overflow is dumped rotting and smelly, in the rivers.

A few months ago, I visited the Sycamore Creek Wastewater facility outside of Cincinnati. This is an 8 million gallon per day plant that uses the “extended aeration process”, shown in the sketch below. I noticed several things I liked: the high throughput (the plant looks no bigger than our 2-3 million gallon plants) and the lack of a bad smell, primarily. The Sycamore Creek plant had an empty hole where the primary clarifier had once been. Lacking this clarifier, the screened sewage could not sit and pop. Instead it goes directly from grit removal to the oxidation reactor, a reactor that looks no bigger than in our plants. This reactor manages a four times higher throughput, I think, because of a higher concentration of cellular catalyst. Consider the following equation derived in a previous post:

ln C°/C = kV/Q.

Here, C° and C are the incoming and exit concentrations of soluble organic; k is the reaction rate, proportional to cellular concentration, V is the volume of the reactor, Q is the flow, and ln is natural log. The higher cellular concentration in the extended aeration plant results in an increased reaction rate, k. The higher the value of k, the higher the allowed flow, Q, per reactor volume, V.

The single clarifier at the end of the Sycamore Creek plant does not look particularly big. My sense is that it deals with a lot more sludge and flow than is seen in our 2nd clarifiers because (I imaging) the sludge is higher density, thus faster settling. I expect that, without the 1 clarifier, there is extra iron and sulfate in the sludge, and more large particles too. In our plants, a lot of these things are removed in the primary clarifier. Sludge density is also increased, I think, because the Cincinnati plant recycle a greater percentage of the sludge (I list it as 90% in the diagram). Extra iron in the reactor also helps to remove phosphates from the water effluent that flows back to the river, an important pollution concern. Iron phosphates are insoluble, and thus leave with the sludge. In Oakland county’s activated sludge plants, it is typical to add iron to the reactor or clarifier. In Cincinnati’s extended aeration plant, I’m told, iron addition is generally not needed.

Typical Oakland Sewage plant, activated sludge process with a primary clarifier.

Cincinnati sewage treatment plant, extended aeration process with no primary clarifier.

The extended aeration part of the above process refers to the secondary sludge oxidizer, the continuously stirred tank reactor, or CSTR shown at lower right above. The “CSTR” is about 1/5 the volume of the main oxidation reactor and about the size of a clarifier. Oxidation in the CSTR compliments that in the main oxidizer removing organics, making bio-polymer, and improving (I think) the quality of the sludge that goes to the farms. Oxidation in the CSTR reduces the amount of sludge that goes to the farms. The sludge that does go, is  less-toxic and more concentrated in organics and minerals. I’m not sure if the CSTR product is as good as the product from an anaerobic digester, or if the CSTR is cheaper to operate, but it looks cheaper since there is no roof, and no (or minimal) heating. This secondary oxidizer is very efficient at removing organics because the cellular catalyst concentration is very high – much higher than in the main oxidizer.

During periods of high load, early morning, the CSTR seems to serve as a holding tank so that sludge does not build up in the clarifier. Too much sludge in the clarifier can start to rot, and ruin the effluent quality. The way you tell if there is too much sludge, by the way, is through a device called the “sludge judge.” I love that name. The Cincinnati plant used a centrifugal drier; none of our plants do. The Cincinnati plant had gap the bubble spots of the main oxidizer. This is good for denitrification, I’m told, an important process that I discuss elsewhere.

The liquid output of their clarifier (or ours) is not pure enough to be sent directly to the river. In this plant, the near-pure water from the clarifier is sent to a trickling filter, a bed of sand and anthracite that removes colloidal remnants. Some of our plants do the same. I suspect that the large surface area in this filter is also home to some catalysis: last stage oxidation of remaining bio-organics. On a regular basis, the filter bed is reverse-flushed to remove cellular buildup, slime, and send it to the beginning of the process. The trickling filter output is then sent to an ultraviolet, bacteria-killing step before being released to the rivers. All in all, I suspect that an extended aeration process like this is worth looking into for Oakland County, especially for our North Pontiac sewage treatment facility. That plant is particularly bad smelling, and clearly too small to treat all its sewage. Perhaps we can increase the throughput and decrease the smell at a minimal cost.

Dr. Robert E. Buxbaum, December 18, 2018. I’m running for water commissioner of Oakland county, MI. If you like, visit my campaign site. Here are some sludge jokes and my campaign song.

A logic joke, and an engineering joke.

The following is an oldish logic joke. I used it to explain a conclusion I’d come to, and I got just a blank stare and a confused giggle, so here goes:

Three logicians walk into a bar. The barman asks: “Do all of you want the daily special?” The first logician says, “I don’t know.” The second says, “I don’t know.” The third says, “yes.”

The point of the joke was that, in several situations, depending on who you ask, “I don’t know” can be a very meaningful answer. Similarly, “I’m not sure.”  While I’m at it, here’s an engineering education joke, it’s based on the same logic, here applied:

A team of student engineers builds an airplane and wheel it out before the faculty. “We’ve designed this plane”, they explain, “based on the principles and methods you taught us. “We’ve checked our calculations rigorously, and we’re sure we’ve missed nothing. “Now. it would be a great honor to us if you would join us on its maiden flight.”

At this point, some of the professors turn white, and all of them provide various excuses for why they can’t go just now. But there is one exception, the dean of engineering smiles broadly, compliments the students, and says he’ll be happy to fly. He gets onboard the plane seating himself in the front of the plane, right behind the pilot. After strapping himself in, a reporter from the student paper comes along and asks why he alone is willing to take this ride; “Why you and no one else?” The engineering dean explains, “You see, son, I have an advantage over the other professors: Not only did I teach many of you, fine students, but I taught many of them as well.” “I know this plane is safe: There is no way it will leave the ground.”heredity cartoon

Robert Buxbaum, November 2i, 2018.  And one last. I used to teach at Michigan State University. They are fine students.

Of God and gauge blocks

Most scientists are religious on some level. There’s clear evidence for a big bang, and thus for a God-of-Creation. But the creation event is so distant and huge that no personal God is implied. I’d like to suggest that the God of creation is close by and as a beginning to this, I’d like to discus Johansson gauge blocks, the standard tool used to measure machine parts accurately.

jo4

A pair of Johansson blocks supporting 100 kg in a 1917 demonstration. This is 33 times atmospheric pressure, about 470 psi.

Lets say you’re making a complicated piece of commercial machinery, a car engine for example. Generally you’ll need to make many parts in several different shops using several different machines. If you want to be sure the parts will fit together, a representative number of each part must be checked for dimensional accuracy in several places. An accuracy requirement of 0.01 mm is not uncommon. How would you do this? The way it’s been done, at least since the days of Henry Ford, is to mount the parts to a flat surface and use a feeler gauge to compare the heights of the parts to the height of stacks of precisely manufactured gauge blocks. Called Johansson gauge blocks after the inventor and original manufacturer, Henrik Johansson, the blocks are typically made of steel, 1.35″ wide by .35″ thick (0.47 in2 surface), and of various heights. Different height blocks can be stacked to produce any desired height in multiples of 0.01 mm. To give accuracy to the measurements, the blocks must be manufactured flat to within 1/10000 of a millimeter. This is 0.1µ, or about 1/5 the wavelength of visible light. At this degree of flatness an amazing thing is seen to happen: Jo blocks stick together when stacked with a force of 100 kg (220 pounds) or more, an effect called, “wringing.” See picture at right from a 1917 advertising demonstration.

This 220 lbs of force measured in the picture suggests an invisible pressure of 470 psi at least that holds the blocks together (220 lbs/0.47 in2 = 470 psi). This is 32 times the pressure of the atmosphere. It is independent of air, or temperature, or the metal used to make the blocks. Since pressure times volume equals energy, and this pressure can be thought of as a vacuum energy density arising “out of the nothingness.” We find that each cubic foot of space between the blocks contains, 470 foot-lbs of energy. This is the equivalent of 0.9 kWh per cubic meter, energy you can not see, but you can feel. That is a lot of energy in the nothingness, but the energy (and the pressure) get larger the flatter you make the surfaces, or the closer together you bring them together. This is an odd observation since, generally get more dense the smaller you divide them. Clean metal surfaces that are flat enough will weld together without the need for heat, a trick we have used in the manufacture of purifiers.

A standard way to think of quantum scattering is that the particle is scattered by invisible bits of light (virtual photons), the wavy lines. In this view, the force that pushes two flat surfaces together is from a slight deficiency in the amount of invisible light in the small space between them.

A standard way to think of quantum scattering of an atom (solid line) is that it is scattered by invisible bits of light, virtual photons (the wavy lines). In this view, the force that pushes two blocks together comes from a slight deficiency in the number of virtual photons in the small space between the blocks.

The empty space between two flat surfaces also has the power to scatter light or atoms that pass between them. This scattering is seen even in vacuum at zero degrees Kelvin, absolute zero. Somehow the light or atoms picks up energy, “out of the nothingness,” and shoots up or down. It’s a “quantum effect,” and after a while physics students forget how odd it is for energy to come out of nothing. Not only do students stop wondering about where the energy comes from, they stop wondering why it is that the scattering energy gets bigger the closer you bring the surfaces. With Johansson block sticking and with quantum scattering, the energy density gets higher the closer the surface, and this is accepted as normal, just Heisenberg’s uncertainly in two contexts. You can calculate the force from the zero-point energy of vacuum, but you must add a relativistic wrinkle: the distance between two surfaces shrinks the faster you move according to relativity, but measurable force should not. A calculation of the force that includes both quantum mechanics and relativity was derived by Hendrik Casimir:

Energy per volume = P = F/A = πhc/ 480 L4,

where P is pressure, F is force, A is area, h is plank’s quantum constant, 6.63×10−34 Js, c is the speed of light, 3×108 m/s, and L is the distance between the plates, m. Experiments have been found to match the above prediction to within 2%, experimental error, but the energy density this implies is huge, especially when L is small, the equation must apply down to plank lengths, 1.6×10-35 m. Even at the size of an atom, 1×10-10m, the amount of the energy you can see is 3.6 GWhr/m3, 3.6 Giga Watts. 3.6 GigaWatt hrs is one hour’s energy output of three to four large nuclear plants. We see only a tiny portion of the Plank-length vacuum energy when we stick Johansson gauge blocks together, but the rest is there, near invisible, in every bit of empty space. The implication of this enormous energy remains baffling in any analysis. I see it as an indication that God is everywhere, exceedingly powerful, filling the universe, and holding everything together. Take a look, and come to your own conclusions.

As a homiletic, it seems to me that God likes friendship, but does not desire shaman, folks to stand between man and Him. Why do I say that? The huge force-energy between plates brings them together, but scatters anything that goes between. And now you know something about nothing.

Presidential drinks, smokes, and other vices

I’d written about presidential desks so now presidential drinking and related vices. The US colonials were hard drinkers, and their leaders lead on this front too. The colonials who fought at Lexington and Concord loaded up at Bradford’s Tavern before greeting the British. Meanwhile, safe in Philadelphia, each of the authors of the declaration of Independence drank, on average, two pint tankards of rum per day, likely mixed with water, a mixture called “grog,” or mixed with apple cider, a mix called “the stone fence.”

Washington's bar bill for 55 men.

Washington’s bar bill for 55 men; food was less than 1/4 of the bill, both for the officers and the servants. Note the “Segars” and broken crockery.

The standard of drinking for officers in the colonial army can be seen from the bill for the farewell dinner (right) held at City Tavern in New York. The average man drank more than two bottles of wine, about a quarter bottle of old stock (whiskey)  bottle of beer, porter or cider, and 1/2 bowl of punch. There is also a cost for “segars” and for broken cookery. The servants drank almost as much but not quite. George Washington was considered a very modest drinker in the crowd, avoiding rum mostly, and sticking to Madera wine or dark, “Philadelphia” porter, typically mixed with molasses. He smoked a pipe too, but didn’t have a mistress nor did he fight in any duels; a model for presidents to come. When Washington retired from the presidency, he become the premier distiller in the USA, making thousands of barrels of rye whiskey per year. A good man and a good president, IMHO.

John Adams considered himself a temperance man, and complained of Washington’s lack of refinement. He didn’t smoke at all, and drank only one tankard of hard cider to start the day, followed by beer, Madera and diluted rum (grog). He was priggish and disliked. He also started the pseudo war with France, spent massively to pay off the Barbary pirates, insulted most everyone, and passed the single worst law ever in US history, Our worst president, IMHO, but at least he didn’t overspend.

According to "The Balance, and Columbian Repository" 1806, "A cock tail is a stimulating liquor composed of spirits of any kind, sugar, water and bitters. It is supposed to be an excellent electioneering potion inasmuch as it renders the heart stout and bold, at the same time that it fuddles the head. It is said also, to be of great use to a democratic candidate: because, a person having swallowed a glass of it, is ready to swallow any thing else."

According to “The Balance, and Columbian Repository” May 15, 1806, “– Cock tail then is a stimulating liquor… an excellent electioneering potion inasmuch as it renders the heart stout and bold, at the same time that it fuddles the head… of great use to a democratic candidate: because, a person having swallowed a glass of it, is ready to swallow any thing else.”

Jefferson was a spendthrift who  spent $16,500 in the money of the day (well over $1 million today) on French wine; $11,000 for his time in the Whitehouse and $5,000 for the ministry in Paris. His wine habits, along with his book and furniture buying, led him to be bankrupt twice. The first time, he was bailed out by congress, the second time (at his death) his slaves and property were sold off to pay debts, including his red-haired, slave children. Not a good man, but a good president. He ended Adam’s the pseudo-war with France, defeated the Barbary pirates, and doubled the size of America through the Louisiana purchase.

James Madison, like Jefferson preferred French wine, mostly Champaign, but he didn’t drink much of it, according to the standard of the day. He said that, if he drank any more than 3 or so glasses or he’d wake up with a headache. He also smoked ‘seegars’ until his death at 85: a good man but a poor president. Who would declare war on the most powerful nation on earth without first preparing his army or navy? Dolly Madison is considered the first of the “First Ladies,” for her hostess prowess.

Monroe liked French Champaign and Burgundy. He was the last of the “gentleman presidents; liked as a man and as a president, doing little that was controversial, except perhaps stating the Monroe Doctrine — US control of the Caribbean. He oversaw an “era of good feelings,” where the US grew and wounds healed.

John Quincy Adams was as obnoxious and disliked like his father, “the bitter branch of the bitter tree.” He was a wine-snob who claimed to have conducted a blind taste test with 14 kinds of Madeira and correctly identified 11 of them. After his one-term as president he returned to congress where his last act was to vote against admitting Texas to the union. At least 17 male-line Adams’s have graduated from Harvard; few are remembered fondly.

Andrew Jackson was not a gentleman. He drank whiskey — home made — and smoked cigars along with his wife. He fought about 20 duels, served whiskey proudly to all his guests, and removed the requirement of land to vote. He was a drinker of coffee too, pairing it with cigars, and is reported to have said, “Doctor, I can do anything you think proper, except give up coffee and tobacco.” One famous duel was with his lawyer, Thomas Hart Benton. Benton shot him twice, and they become friends and allies for life. Jackson added the first running water in the white house. The source was soon contaminated by human waste but I can’t complain. We have similar problems in Oakland county today. He also paid down the national debt, leaving Van Buren with a surplus for the first and only time in America. I consider Jackson an excellent president, but have not decided about him as a man.

Van Buren was a heavy drinker, a pipe smoker, a corrupt Tammany man, and a bit of a spendthrift (“Martin Van Ruin”)  He is the only US president to grow up speaking Dutch, not English, and his favored drink was Schiedam, a blue-colored gin favored by New York’s Dutch. Most people could not stand Schiedam, and it led Van Buren to be called “Blue whiskey Van.” Gin is an acquired taste — one that several later presidents would acquire. My guess is that Schiedam is the reason that some modern gins come in blue bottles. Van Buren accomplished nothing of note as president.

William Henry Harrison smoked a pipe and drank nothing harder than cider. Modest drinking differentiated him from hard-drinking Van Buren. His campaign song — Tippicanoe and Tyler too — includes the line “Van is a used-up man”, but modest drinking may have killed him too. He likely died of infected water in the Whitehouse —  something that could have been cured by a bit of whiskey mixed into the infected water. (I’m running for water commissioner my campaign: clean water at an appropriate pressure for fire-fighting.
Explosion_aboard_USS_Princeton

John Tyler, Harrison’s VP, drank and smoked cigars. He kept two kegs of “Lieutenant Richardson’s whiskey” on hand, and Champaign for state dinners. He was a compromiser, who missed dying in an explosion on the USS Princeton because he’d stopped off for a drink. Most of the rest of his cabinet were not so lucky. He was rejected for re-election in favor of Polk, who promised to admit Texas.

James K. Polk was a modest drinker who favored the occasional wine or brandy. He survived his single term in the Whitehouse to die 105 days after leaving the Whitehouse of gastro-enteritis caused by infected water or fruit. A bit of whiskey might have helped. By admitting Texas, Polk started the Mexican – American War. This expanded the US further, all the way to California. I rather like Polk, but most historians do not.

Zachary Tayler, a Whig, “old rough and ready” had been a whiskey man in the army but never drank as president and rarely smoked in the white house. He died 1 1/2 years after taking office, likely killed by the bad water and lack of alcohol. Tayler was against all forms of secession and against the fugitive slave compromise that Clay. I like Tayler and agree with him.

Millard Fillmore was Tayler’s vice president and another non-smoker, he drank Madera wine as had some early presidents. Always concerned with his health, and is said to have installed the first bathtub, installing with it with copper and brass pipes. I suspect that the copper pipes saved Fillmore from DC’s bad water as copper is a fine anti-microbial. Though opposed to slavery, Fillmore signed the fugitive slave compromise that brought California into the union as a free state. The civil war is sometimes blamed on Fillmore, unfairly I think. It could not have been stopped. He died at the ripe age of 74, long after having left the Whitehouse.

Franklin Pierce, a Democrat and alcoholic, was “the hero of many a well-fought bottle”. Not a bad president, in my opinion. He saw the inevitable civil war coming and could not stop it, His wife lost her mind and his children all died. The last one, Benny, by beheading in front of him when a train Pierce and his wife were about to board broke its axle and slid down a hill. Pierce added the Gadson purchase, made the civil service less corrupt, made treaties with Britain and opened Japan. He too is blamed for the civil war by current historians as if they could have done better. He died of cirrhosis at 65, 13 years after leaving office.

James Buchanan, another Democrat was likely our only homosexual president. Buchanan was a life-long bachelor who drank quite a lot. His favorite was originally “Old Monongahela” but switched to J. Baer “finer than the best Monongahela,” buying ten gallons of J.Baer (rye) per week, direct from the distillery. “The Madeira and sherry that he has consumed would fill more than one old cellar, and the rye whiskey that he has ‘punished’ would make Jacob Baer’s heart glad.” Like Pierce, he is blamed by historians for not saving the union, as if this were an easy job that anyone could have done. Buchanan had no problem with the White House water, but was heart-broken when his housemate, William King left to become minister to France.

Lincoln didn’t drink or chew tobacco, nor did he have mistresses, or apparent trouble with the water. He was depressive though, told wonderful stories, some of them true, smoked a pipe, and once almost fought a duel with swords that broken up by the wives of the duelers. A good man and a great president. His son, Robert was present at his murder, and at two other presidential shootings.

Andrew Johnson drank and smoked occasionally, but had a low tolerance. Johnson added Alaska by purchase (Seward’s folly) but is not liked or respected by historians. I consider this unfair: he compares unfavorably to Lincoln, but don’t we all, and he could not smooth reconstruction, a near impossible task. His main impeachment crime was bombastic speech, by the way, a vice he shares with Andrew Jackson and Donald Trump. Like Buchanan and Pierce, I consider him a good president doing a near-impossible job.

Ulysses S. Grant was a Republican, a heavy cigar smoker, but a light drinker. Grant smoked as many as 20 cigars per day (a Grant cigar is 5″ long by 42 ring), but drank only brandy for his health, and not too much of that. Later in life he drank a mixture of wine and cocaine for throat pain from cancer. This stuff, a favorite of Pope Leo, was the inspiration for Coca-Cola. Grant’s campaign song, “Grant Grant Grant” specifically mentions his opposition to the KKK. He did a good job with reconstruction though the Democrats hated him for it. They mocked him as a drunk and worse: “I smoke my weed and drink my gin, playing with the people’s tin.” Grant wrote a great autobiography with the help of Mark Twain.

Hayes, a Republican, didn’t drink at all and opposed others’ drinking. Elected in 1876, he banned liquor of all sorts in the white house, and his wife was known as “Lemonade Lucy.” Hayes is criticized for corruption and for reducing the burdens of reconstruction. His opponent, Tammany Tilden, was at least as corrupt, and a stronger opponent of reconstruction.

Garfield was a beer man who “drank little else.” He tried to reform the civil service, but died from a gunshot and doctor-caused infection shortly after taking office. If his wound had been disinfected he would have probably lived. That’s what Roosevelt did when he was shot.

Chet Arthur, a cigar smoker and enthusiastic drinker, was Garfield’s vice president. When pressured for a no-liquor policy in the White House, he responded: “Madam, I may be the president of the United States, but what I do with my private life is my own damned business!” Arthur liked late night dining that he would finish with Champagne and a cigar. Though his background was in corrupt civil service, as president he did his best to remove this corruption from the civil service. A good president, IMHO.

Ma ma, Ma ma, where's my pa?

Ma ma, Ma ma, where’s my pa?

Grover Cleveland was a cigar and beer man. Weighing 250 lbs, he was known as ‘Big Steve’ or ‘Uncle Jumbo,” In the white house, he limited himself to a gallon of beer a night. That is he drank four tankards of 1 liter each. He’d drank more before becoming mayor of Baltimore. He fathered a child at that time by seduction, perhaps date rape, of Maria Halpin, a 38-year-old sales clerk. She named the child Oscar Folsom Cleveland, the two last names suggesting she was not sure of the father. Cleveland and Folsom had Maria sent to an insane asylum (she was not crazy) and had Oscar was sent to an orphanage. In the end, Maria was freed and Oscar was adopted by Dr. King a trustee of the orphanage. None of this horrible behavior stopped Cleveland from becoming mayor and president. Cleveland married the 21-year-old daughter of his friend, Folsom. Rutherford Hayes was revolted by it all: “Cleveland … is a brute with women.” Cleveland smoked foot-long, ‘supercoronas’ that he received as gifts, using these cigars to influence people and conversations, similar to Churchill. Not a good man, nor a particularly good president, IMHO. Baby Ruth candy was not named after Cleveland’s daughter Ruth, but after the baseball player. IMHO, the candy company claimed otherwise only to avoid paying royalties. Cleveland is remembered fondly by historians, but not by me. I read two of his books.

Benjamin Harrison didn’t drink, but he did smoke cigars and he allowed liquor in the white house though prohibition was a growing issue. He annexed Hawaii, improved the navy, and replaced the “spoils system” for civil service jobs with a merit system. He also tried unsuccessfully to provide voting rights for African-Americans. The move failed in the senate. Cleveland defeated him in his run for a second term by pointing out that tariffs were too high. A tariff battle would dominate the Democrat / Republican split for a generation, and has recently reappeared. Modern historians don’t much like Harrison as he didn’t succeed in providing civil rights, as if that were an easy battle.

mckinleyMcKinley drank scotch whiskey — Dewar’s, a brand provided by Andrew Carnegie, and he smoked several cigars per day. He would not smoke in public though there is artwork, as at right, and the comment that “one never saw McKinley without a cigar in his mouth except at meals or when asleep.’. The McKinley delight is a variant of the Manhattan made with 3 oz of rye whiskey (at least 100 proof), 1 oz. sweet vermouth, 2 dashes of cherry brandy, and 1 dash absinthe. McKinley was shot and started to recover before dying from doctor-caused infection (he used the same doctor the Garfield had).

Theodore Roosevelt, was McKinley’s VP, and is one of the most beloved and colorful presidents in US history. He smoked cigars starting when he was 8, but swore off them later. He drank modestly, a version of the mint julep and served it to anyone who’d play tennis with him. Roosevelt’s version used rye plus brandy instead of Bourbon: 2-3 oz of rye whiskey, 10 to 12 fresh mint leaves “muddled” with a splash of water, a sugar cube, ¼ oz. of brandy and a sprig or two of mint as a garnish. The fresh mint was grown on the Whitehouse grounds. T. Roosevelt wrote some 30 books (I’ve read four or five) they are all wonderful. Roosevelt did daring things, like ride a moose, and survived being shot by leaving the bullet where is was; here’s a photo and essay. I don’t understand why so many US presidents drank rye and not Bourbon (Bourbon — corn whiskey — had been invented in the late 1700s and is tastier, IMHO). One of TR’s most famous speeches, “the man in the arena”, was given at the Sorbonne 1910. He claimed that being a critic was not much of an achievement.

William H. Taft smoked cigars and like Champaign, but rarely drank; he was on a perpetual diet. He tried to continue Roosevelt’s programs, but got little done. Still the country did well. He’s most remembered for the “7th inning stretch” break near the end of every baseball game.

Woodrow Wilson drank scotch and smoked cigarettes. His campaign slogan, “Wilson that’s all” was a whiskey slogan. Prohibition began during Wilson’s time in office: it was supposed to help women, but did not. It brought corruption and misery. Here’s an anti-alcohol song of the day: “behind those swinging doors.”

Harding's humidor - a massive thing

Harding’s humidor – a massive thing

Despite prohibition, Harding had poker nights twice a week where he smoked cigars, and the whiskey flowed freely. He also had at least 7 mistresses; he got two of them pregnant. Not a good man or a particularly good president. He died in office, perhaps killed by his wife or by his lifestyle.

Calvin Coolidge was Harding’s VP. Coolidge smoked cigars and drank sweet, Tokay wine. As president he cut spending and taxes, paid down the debt, and did not say much. Much of the detail work was done by his secretary of commerce, Herbert Hoover. Here is the Coolidge cooler: 1.5 oz. of Vermont White vodka, ½ oz. of American whiskey, 2 oz. of orange juice, Club soda. A good man and a good president, IMHO.

H. Hoover liked good wine and dry gin-martinis, but didn’t drink either in the white house as he respected prohibits as his predecessors did not. Also, his wife poured out his extensive wine collection. He is blamed for the great depression, unfairly I think. The depression hit all other industrial countries at the same time (most economies revered before ours did). Hoover’s dying request, at 80, was for a good, dry martini. He is the first gin man since Van Buren, but not the last.

FDR and Churchill

FDR and Churchill. They drank Champaign and whiskey.

FDR was the first gentleman president since Monroe. He smoked 2 packs of cigarettes per day and drank gin martinis, very dry. Also, “old-fashioneds”, and daiquiris mixed with orange juice (a rum sizzle it’s called). The old-fashioned is made of whiskey, sugar, water, and bitters. FDR spent his last day with one of his mistresses (his wife had a mistress too) and his last words were to recount how much Churchill drank. FDR also took cocaine. It was a fairly normal medication at the time. He took some before giving the famous speech “December 7, 1941….” I question the harsh sentences we now give to users of this drug.

Truman was not a gentleman, but a fine president, IMHO. He swore with abandon, was a bourbon man, and liked to play poker with his buddies late into the night. He liked to include a shot of bourbon with his breakfast before his morning walk, took another shot “for freedom” when he entered the senate, drank bourbon with his poker buddies, and sometimes had bourbon with dinner. Truman’s buddies and colleagues were impressed that he was always up early though, and ready for work. He worked hard, didn’t smoke, and was true to his wife. He lived a long life, dying at 88 in 1972.

Eisenhower typically drank scotch with ice.

Eisenhower drank scotch over ice.

Eisenhower liked scotch, golf, smoking cigarettes and cigars, and entertaining. He had a mistress (his driver) and mostly entertained business men who he would sound out for advice on the issues of the day. He limited himself to only one drink a day or a bit of a second because of his health. It’s a good standard. Eisenhower was one of the first presidents to have a secret-service nickname, “scorecard” because of his love of golf. Before him, only Wilson played more golf.

John F. Kennedy had many mistresses, and was the last to smoke cigars in public while president. He drank classy drinks like Daiquiris, Bloody Marys and Heineken beer, imported from Holland. The Daiquiri is made of rum, lime, sugar, and water. Kennedy lived on amphetamines from “Dr Feelgood,” his personal physician. He is supposed to have tried LSD and marijuana too, His secret service nickname was “Lancer”, a reference to Lancelot, the philandering knight of Camelot fame. A famous story of Kennedy is that, right before signing the embargo of Cuba, he instructed an assistant to buy up every Cuban cigar he could find. He bought over 1000 and then signed the embargo. Not one of my favorite presidents. Jacquline Kennedy smoked like a train, Salems.

Screen Shot 2018-09-13 at 10.58.11 PMLBJ was a cigarette smoker and a heavy drinker who’s responsible for “Bourbon and Branch” becoming the semi-official drink of Texans. Branch water is just another name for water, BTW. He also drank scotch: Cutty Sark or Teachers, and used his ability to hold liquor in negotiations. He’d greet congressional opponent with two bottles, requesting that they finish them before talking. After that, they were pliable, especially since, sometimes he’d have his diluted. A very good president, IMHO: he was able to implement civil right law that had eluded a century of presidents.
nixon-cigars

Nixon is hated, unfairly I think. He liked fine wine and fruity mixed drinks like Mai Tais, but served mediocre wine to guests. He was an ex-smoker of cigarettes – switched to cigars by the time he was president, but smoking them in private, and handing out bubble gum cigars as a campaign prop. Mai Tais are wonderful drinks, the recipe is 60 ml Jamaican and Martinique Rums, 25 ml Fresh Lime Juice, 15 ml Orange Curaçao, 15 ml Orgeat, 3-4 Crushed Ice Cubes. Nixon ended the Vietnam war and began good relations with Russia and China. I also started the EPA, and is the first president to deal well with the Indians, dividing Alaska land nicely. Watergate was his downfall, helped in part by Deep Throat, the second in command of the FBI who was bypassed for a promotion.

Gerald Ford smoked a pipe in public, and liked gin martinis during lunch or with friends, or gin and tonics in the summer. He didn’t drink to excess, and most people liked him. He’s criticized for thinking Russia was an enemy, and for not stopping inflation, as if anyone else could have done it.

Carter didn’t drink or smoke, and was critical of those who did, a possible swipe at Ford. When he had an arms summit with the Soviets, Carter toasted the soviets with a small glass of white wine. He’s the least favorite president of my life-time; he backed tyrants and thought that deficit spending would cure the economy. He got nothing more than foreign policy abuse and stag-flation (inflationary recession). Carter’s secret service name was “Deacon,” because of his church leanings. 114000446

Reagan liked California wine and the Orange Blossom Special: 1 oz. (or slightly less) vodka, 1 oz. of either grenadine or sweet vermouth, 2 oz. fresh orange juice, served over ice. Reagan smoked before becoming president, and ate jelly beans as a way of quitting. They became his signature dish. As president, Reagan was a deficit spender but he got better results than Carter had perhaps because he achieved his deficit by lowering taxes.

George HW Bush drank beer or vodka martinis in moderation, and smoked the occasional cigar. He may have had a mistress, too. A vodka martini is a mix of vodka and dry vermouth mixed in at about 4 to 1. I find it flavorless. He liked (likes) sailing and skydiving. Of the recent presidents, he is the fondest remembered by the white house staff. The soviet union collapsed in his day. A good president and a good man.

Screen Shot 2018-09-13 at 10.58.40 PMBill Clinton smoked pot in college and after, though he claims to have not inhaled. In the white house he smoked cigars, but not in public, and liked an English drink called a snake-bite: 50% beer, 50% hard cider. His secret service name was “eagle,” perhaps because of his eagle eye for women. Several women claimed that he’d pressured them into sex. Clinton denied all charges until one, a 22-year-old intern, turned up with the stained dress. He was a good president but a lousy person. His cigar of choice, the Gurkha Grand Reserve, is slightly longer and wider than the Grant cigar, 6 inches by 50 ring.

George W. Bush had been a heavy drinker in college but completely swore off by the time he was president. When his father had been president, his secret service name had been “Tumbler,” a reference to his drinking and its ill-effects. He requested a different nickname as president, Timberwolf. It sounds vaguely like Tumbler. His main presidential accomplishment was the war on terror, such as it is.

Obama, like Clinton, smoked pot in his youth. He switched to beer and cigarettes in the White house but doesn’t do either in public. The picture at right has him holding the glass. His secret service name is “Renegade,” and his main achievement, seems to have been a close rapport with the countries of Islam. While I can’t say that pot helped either of these men, it does not seem to have hurt them, or society. Thus, I can not favor harsh sentencesusa-whitehouse-beer-1

Trump does not drink or smoke. He has had some affairs before becoming president, but they seem to have been consensual, and he seems to have stopped by the time he entered the Whitehouse. Trump’s church leaning is positivist, and his secret service nickname is “Mogul.” He seems committed to tariffs as a way to restart the economy and as a way to bring down the debt. I wish him success.

It is not clear who is in charge when the president is drunk, nor is the law clear about presidential smoking in the Whitehouse: It is both a public building and a private residence

Robert E. Buxbaum, October 18, 2018. As a side note: The 23rd Prime Minister of Australia, Bob Hawke (1954) held the Guinness Record for fast beer drinking: 2.5 pints in under 11 seconds !

Getter purifiers versus Membrane purifiers

There are two main types of purifiers used for gases: getters and membranes. Both can work for you in almost any application, and we make both types at REB Research – for hydrogen purification mostly, but sometimes for other applications. The point of this essay is which one makes more sense for which application. I’ll mostly talk about hydrogen purification, but many of the principles apply generally. The way both methods work is by separating the fast gas from the slower gas. With most getters and most membranes, hydrogen is the fast gas. That is to say, hydrogen usually is the component that goes through the membrane preferentially, and hydrogen is the gas that goes through most getters preferentially. It’s not always the case, but generally.

Scematic of our getter beds for use with inert gasses. There are two chambers; one at high temperature to remove water, nitrogen, methane, CO2, and one at lower temperature the remove H2. The lower temperature bed can be regenerated.

Our getter beds for use with inert gasses have two chambers; one is high temperature to remove water, nitrogen, etc. and one at lower temperature the remove H2. The lower temperature bed can be regenerated.

Consider the problem of removing water and similar impurities from a low-flow stream of helium for a gas chromatograph. You probably want to use a getter because there are not really good membranes that differentiate helium from impurities. And even with hydrogen, at low flow rates the getter system will probably be cheaper. Besides, the purified gas from a getter leaves at the same pressure as it entered. With membranes, the fas gas (hydrogen) leaves at a lower pressure. The pressure difference is what drives membrane extraction. For inert gas drying our getters use vanadium-titanium to absorb most of the impurities, and we offer a second, lower temperature bed to remove hydrogen. For hydrogen purification with a bed, we use vanadium and skip the second bed. Other popular companies use other getters, e.g. drierite or sodium-lead. Whatever the getter, the gas will leave purified until the getter is used up. The advantage of sodium lead is that it gets more of the impurity (Purifies to higher purity). Vanadium-titanium removes not only water, but also oxygen, nitrogen, H2S, chlorine, etc. The problem is that it is more expensive, and it must operate at warm (or hot) temperatures. Also, it does not removed inert gases, like helium or argon from hydrogen; no getter does.

To see why getters can be cheaper than membranes if you don’t purify much gas, or if the gas starts out quite pure, consider a getter bed that contains 50 grams of vanadium-titanium (one mol). This amount of getter will purify 100 mols of fast gas (hydrogen or argon, say) if the fast gas contains 1% water. The same purifier will purify 1000 mols of fast gas with 0.1% impurity. Lets say you plan to use 1 liter per minute of gas at one atmosphere and room temperature, and you start with gas containing 0.1% impurity (3N = 99.9% gas). Since the volume of 100 mols of most gases a these conditions is 2400 liters. Thus, you can expect our purifier to last for 400 hours (two weeks) at this flow rate, or for four years if you start with 99.999% gas (5N). People who use a single gas chromatograph or two, generally find that getter-based purifiers make sense; they typically use only about 0.1 liters/minute, and can thus get 4+ years’ operation even with 4N gas. If you have high flows, e.g. many chromatographs or your gas is less-pure, you’re probably better off with a membrane-based purifier, shown below. That what I’ll discuss next.

Our membrane reactors and most of our hydrogen purifiers operate with pallium-membranes and pressure-outside. Only hydrogen permeates through the palladium membrane.

Our membrane reactors and most of our hydrogen purifiers operate with pallium-membranes and pressure-outside. Only hydrogen permeates through the palladium membrane.

The majority of membrane-based purifiers produced by our company use metallic membranes, usually palladium alloys, and very often (not always) with pressure on the outside. Only hydrogen passes through the membranes. Even with very impure feed gases, these purifiers will output 99.99999+% pure H2 and since the membrane is not used up, they will typically operate forever so long as there is no other issue — power outages can cause problems (we provide solutions to this). The main customers for our metallic membrane purifiers are small laboratories use and light manufacturers. We also manufacture devices that combine a reformer that makes 50% pure hydrogen from methanol + steam where the membranes are incorporated with the reactor — a membrane reformer, and this has significant advantages. There is no equivalent getter-based device, to my knowledge because it would take too much getter to deal with such impure gas.

Metal membranes are impermeable to inert gases like helium and argon too, and this is an advantage for some customers, those who don’t want anything but hydrogen. For other customers, those who want a cheaper solution, or are trying to purify large amounts of helium, we provide polymeric membranes, a lower cost, lower temperature option. Metal membranes are also used with deuterium or tritium, the higher isotopes of hydrogen. The lighter isotopes of hydrogen permeate these membranes faster than the heavier ones for reasons I discuss here.

Beavers, some of the best dam builders

I ran for water commissioner in 2016 (Oakland county, Michigan; I’ll be running again in 2020), and one of my big issues was improving our rivers. Many are dirty and “flashy”. Shortly after a rain they rise too high and move dangerously fast. At other times, they become, low, smelly, and almost disappear. There are flash floods in these rivers, few fish or frogs, and a major problem with erosion. A big part of a solution, I thought, would be to add few small dams, and to refurbish a few others by adding over-flow or underflow weirs. We had a small dam in the middle of campus at Michigan State University where I’d taught, and I’d seen that it did wonders for river control, fishing, and erosion. The fellow I was running against had been removing small dams in the belief that this made the rivers “more natural”. The Sierra Club thought he was right doing this; the fishing community and some homeowners and MSU alumni thought I was. My problem was that I was a Republican running in a Democratic district. Besides, the county executive, L. Brooks Patterson (also a Republican) was a tightwad. Among my the first stops on my campaign trail was to his office, and while he liked many of my ideas, and promised to support me, he didn’t like the idea of spending money on dams. I suggested, somewhat facetiously, using beavers, and idea that’s grown on me since. I’m still not totally convinced it’s a good idea, but bear with me as I walk you through it.

Small dam on the Red Cedar River at Michigan State University behind the Administration Building. The dam provided good fishing and canoeing, and cleaned the water somewhat.

The picture at right shows the dam on the Red Cedar River right behind the Administration building at Michigan State University, looking south. During normal times the dam slows the river flow and raises the water level high enough to proved a good canoe trail, 2 1/2 miles to Okemos. Kids would fish behind the dam, and found it a very good fishing spot. The slow flow meant less erosion, and some pollution control. The speed of flow and the height of the river are related; see calculation here. After a big rain, a standing wave (a “jump”) would set up at the dam, raising its effective height by three or four feet. Students would surf the standing wave. More importantly, the three or four feet of river rise provided retention so that the Red Cedar did little damage. Some picnic area got flooded, but that was a lot better than having a destructive torrent. Here’s some more on the benefits of dams.

Between July 31 and Aug 1 the Clinton River rose nine feet in 3 hours, sending 130,000,000 cubic feet of water and sewage to lake St Clair.

Between July 31 and Aug 1 the Clinton River rose nine feet in 3 hours, sending 130,000,000 cubic feet of water to lake St Clair.

The Sierra club supported (supports) my opponent, in part because he supports natural rivers, without dams. I think they are wrong about this, and about their political support in general. Last night, following a 1 1/2 inch rain, the Clinton River flash flooded, going from 5.2 feet depth to 14 feet depth in just two hours. My sense is that the natural state of our rivers had included beavers and beaver dams until at least the mid 1700s. I figured that a few well-designed dams, similar to those at Michigan State would do wonders to stop this. Among the key locations were Birmingham, on the Rouge, Rochester, near Oakland University, Auburn Hills, and the Clinton River gorge, and near Lawrence Technical University. If we could not afford to build man-made dams, I figured we could seed some beaver into nearby nature areas, and let the beavers dam the rivers for free. It would bring back the natural look of these areas, as in the picture below. And engineers at Lawrence Tech and Oakland University might benefit from seeing the original dam engineers at work.

Beaver dam on a branch of the Huron River. A rather professional and attractive job at a bargain price.

Beavers are remarkably diligent. Once they set about a task, they build the basics of a dam in a few days, then slowly improve it like any good craftsman. As with modern dams, beaver dams begin with vertical piles set into the river bottom. Beavers then fill in the dam with cross-pieces, moving as much as 1000 lbs of wood in a night to add to the structure and slow the flow. They then add mud. They use their hearing to detect leaks, and slowly plug the leaks till the dam is suitably tight. Most of the streams I identified are narrow and pass through wooded areas. I think a beaver might dam them in a few days. Based on the amount of wood beavers move, and the fact that beavers are shaped like big woodchucks, I was able to answer the age-old question: how much wood would a woodchuck chuck if a woodchuck could chuck wood — see my calculation here.

Me, visiting the DNR to talk beavers

Me, visiting the DNR to talk beavers

There are a few things to check out before I start hiring beavers to take care of Oakland county flooding, and I have not checked them all out yet. Beavers don’t necessarily build where you want or as solidly, and sometimes they don’t build at all. If there are no predators, beavers can get lazy and just build a low-water lodge and a high water lodge, moving from one to the other as the river rises and falls. Hiring a beaver is like hiring an artistic contractor, it seems: you don’t necessarily get what you ask for, and sometimes you get more. Given the flash flooding we have, it’s hard to picture they’d make things worse, but what do I know? In some cases, e.g. the Red Run near the 12 towns drain, the need is for more than a beaver can deliver. Still, without beavers, the need would be for a billion gallons of retention on the Clinton alone, a 10 billion dollar project if carried out as my opponent likes to build. So, with no budget to work with, my next stop was at the Department of Natural Resources Customer Service Center (Lansing). I had some nice chats with beaver experts, and I’m happy to say they liked the idea, or at least they were not opposed. I’ve yet to talk to the Michigan director of dams, and will have to see what he has to say, but so far it seems like, if I get elected in 2020, I’ll be looking for some hard-working beavers, willing to relocate. I’d like to leave it to Beaver.

Robert E. Buxbaum, August 2, 2018. I still don’t get the Sierra Club’s idea of what a natural river would look like, or their commitment to Democrats. In my opinion, a river should include beavers, fish, and fishermen, and drainage should be done by whoever can do it best. Sierra club folks are welcomed to comment below.

The Great, New York to Paris, Automobile race of 1908.

As impressive as Lindberg’s transatlantic fight was in 1926, more impressive was George Schuster driving and winning the New York to Paris Automobile race beginning in the dead of winter, 1908, going the long way, through Russia. As of 1908, only nine cars had ever made the trip from Chicago to California, and none had done it in winter, but this race was to go beyond California, to Alaska and then over the ice through Russia and to Paris. Theodore Roosevelt was president, and Americans were up to any challenge. So, on February 12, 1908 there congregated in Times Square, New York, a single, US-made production car, along with five, specially made super-cars from Europe; one each from Italy and Germany; and three from France. The US car, a Thomas Flyer (white), is shown in the picture below. The ER Thomas company sent along George Schuster, as an afterthought: he was a mechanic and test-driver for the company, and was an ex bicycle racer. The main driver was supposed to be Montague Roberts, a dashing sportsmen, but the fellow dropped out in Cheyenne, Wyoming. Schuster reached the Eiffel tower on July 30, 1908, 169 days after leaving New York. The Germans and Italians followed. None of the French super-cars got further than Vladivostok, and one dropped out after less than 100 miles.

The race was sponsored by The New York Times and Le Matin, a Paris newspaper. They offered a large trophy, a cash prize of $1000, not enough to pay for the race, and the prospect of fame. The original plan was for drivers to go from New York to San Francisco, then to Seattle by ship, and Northern Alaska, driving to Russia across the Arctic ice. That plan was abandoned when Schuster, the first driver to reach Alaska, discovered ten foot snows outside of Valdez. The race was modified so that travel to Russia would be by ship. Schuster took his Thomas to Russia from Alaska, the other two drivers reached Russia from Seattle by way of Japan. Schuster was given a bonus of days to account for having taken the longer route. Because of his detour, he was the last to arrive in Russia. From Japan, the route was Vladivostok, Omsk, Moscow, St. Petersburg, Berlin, and Paris, 21,900 miles total; 13,341 miles driven. Schuster drove most of those 13,341 miles, protected by his own .32-caliber pistol, and mostly guided by the stars and a sextant. He’d taught himself celestial navigation as there were no roadmaps, and hardly any roads.

George Schuster driving the Thomas Flyer with another mechanic, George Miller, the Flyer was only American entry, and the only production motorcar in the race. Note that the flag has only 45 stars.

The ship crossing of the Pacific was a good idea given that, even in the dead of winter, global warming meant that the arctic could not be relied upon to be solid ice. As it was, Schuster had to content with crossing the Rockies in deep snow, and crossing Russia in the season of deepest mud. He reached the Eiffel tower at 6 p.m. on July 30, 1908. The German car had arrived in Paris three days ahead of Schuster, but was penalized to second place because the German team had avoided the trip to Alaska, and had traveled some 150 km of the Western US by railroad while Schuster had driven. The Italian team reached Paris months later, in September, 1908. That the win went to the only production car to compete is indicative, perhaps of the reliability that comes with mass production. That Mr. Schuster was not given the fame that Lindberg got may have to do with the small size of the prize, or with him being a mechanic while Lindberg was a “flyer”. Flyers were sexy; even the car was called a flyer. The Times saw fit to hardly mention Schuster at all, and when it did, it spelled his name wrong. Instead the Times headline read, “Thomas Flyer wins New York to Paris Race.” You’d think the car did it on its own, or that the driver was named Thomas Flyer.

The Times could not get enough of Montague Roberts; the driver of the first leg was famous and photographic. They tried to get Roberts to drive the last few miles into Paris, “once the roads were good”. And Roberts was the one chosen to drive in the hero-parade in New York, Schuster rode too, but didn’t drive. Schuster was feted by Theodore Roosevelt, though, who said he liked people “who did things.” Schuster said he’d never do a race like that again, and he never did race again.

The race did wonders for the reputation of American automobiles, and greatly spurred the desire for roads, but it did little or nothing for the E.R.Thomas company. Thomas cars were high cost, high power models, and they lost out in the marketplace to Henry Ford’s, low-cost Model T’s. You’d think that, in the years leading up to WWI, the US Army might buy a high cost, high reliability car, but they were not interested, and the Thomas company did little to capitalize on their success. The Flyer design that won the race was discontinued. It was a 60 hp, straight 4 cylinder engine version, replaced by lower cost Flyers with 3 cylinders and 24 hp. Shortly after that, Edwin R. Thomas, decided to drop the Flyer altogether. His company went bankrupt in 1912, and was bought by Empire Smelting. The original Flyer was sold in 1913 at a bankruptcy action, lot #1829, “Famous New York to Paris Racer.”

ER Thomas went on to found another car company, as was the style in those days. Thomas-Detroit went on make similar cars to the Flyer, but cheaper. The largest, the K-30, was only 30 hp. The original Thomas Flyer is now in the National Automobile Museum, Reno Nevada. after being identified by Schuster and restored. Here is a video showing the original Flyer being driven by a grandson of George Schuster. There is a lower-power Thomas Flyer (black) in a back space of the Henry Ford museum (Detroit). Protos vehicles, similar to the one that came in second, were produced for the German military through WWI. Their manufacturer, Siemens, benefited, as did the German driver.

The Thomas engine (and the Protos) engine) live on in a host of cars with water-cooled, four-cylinder, straight engines. In 1922, Chalmers-Detroit merged with Maxwell and continued to produce versions of the old Flyer design, now with an internal drive-shaft. The original Flyer was powered via a gear-chain, like a bicycle. In 1928, Maxwell was sold to Chrysler. Chrysler persists in calling their high-power, four-cylinder engines by the name Chalmers. As for Schuster, when ER Thomas closed its doors, he had still not been paid for his time as a race driver. He went to work for Pierce-Arrow, another maker of large, heavy vehicles. The “cheaper by the dozen” family (two parents, 12 kids) drove a Pierce-Arrow.

The Great race appears in two documentaries and two general audience movies, both comedies. The first of these was Mishaps of the New York–Paris Race, released by Georges Méliès, July 1908, just about as the Flyer was entering Paris. The second movie version  “The Great Race” was released in 1965. It’s one of my favorite movies, with Jack Lemon as the Protos driver (called Dr. Fate in the movie), Tony Curtis as “The Great Leslie”, the Flyer driver. For the movie, the Flyer is called “The Leslie”, and with Natalie Wood as a female reporter who rides along and provides the love interest. In the actual race reporters from the New York Times, male, traveled in the Flyer’s rear seat sending stories back by carrier pigeon.

As a bit of fame, here’s George Schuster in 1958 on “What’s my secret.” He was 85, and no one knew of him or the race. Ten years later, in 1968, Schuster finally received his $1000 prize, but still no fame. A blow-by-blow of the race can be found here, in Smithsonian magazine. There is also an article about the race in The New York Times, February 10, 2008. This article includes only two pictures, a lead picture showing one of the French cars, and another showing Jeff  Mahl, the grandson of George Schuster, and a tiny bit of the flyer. Why did the New York Times choose these pictures? My guess is it’s the same reason that they reported as they did in 1908: The French car looked better than the Flyer, and Jeff Mahl looked better than George Schuster.

Robert Buxbaum, July 20, 2018. What does all this mean, I’ve wondered as I wrote this essay. There were so many threads, and so many details. After thinking a bit, my take is that the movie versions were right. It was all a comedy. Life becomes a comedy when the wrong person wins, or the wrong vehicle does. A simple mechanic working for a failing auto company beat great drivers and super cars, surpassing all sorts of obstacles that seem impossible to surpass. That’s comedy, It’s for this reason that Dante’s Divine Comedy is a comedy. When we see things like this we half-choose to disbelieve, and we half-choose to laugh, and because we don’t quite believe, very often we don’t reward the winner as happened to Schuster for the 60 years after the race. Roberts should have won, so we’ll half-pretend he did.

Isotopic effects in hydrogen diffusion in metals

For most people, there is a fundamental difference between solids and fluids. Solids have long-term permanence with no apparent diffusion; liquids diffuse and lack permanence. Put a penny on top of a dime, and 20 years later the two coins are as distinct as ever. Put a layer of colored water on top of plain water, and within a few minutes you’ll see that the coloring diffuse into the plain water, or (if you think the other way) you’ll see the plain water diffuse into the colored.

Now consider the transport of hydrogen in metals, the technology behind REB Research’s metallic  membranes and getters. The metals are clearly solid, keeping their shapes and properties for centuries. Still, hydrogen flows into and through the metals at a rate of a light breeze, about 40 cm/minute. Another way of saying this is we transfer 30 to 50 cc/min of hydrogen through each cm2 of membrane at 200 psi and 400°C; divide the volume by the area, and you’ll see that the hydrogen really moves through the metal at a nice clip. It’s like a normal filter, but it’s 100% selective to hydrogen. No other gas goes through.

To explain why hydrogen passes through the solid metal membrane this way, we have to start talking about quantum behavior. It was the quantum behavior of hydrogen that first interested me in hydrogen, some 42 years ago. I used it to explain why water was wet. Below, you will find something a bit more mathematical, a quantum explanation of hydrogen motion in metals. At REB we recently put these ideas towards building a membrane system for concentration of heavy hydrogen isotopes. If you like what follows, you might want to look up my thesis. This is from my 3rd appendix.

Although no-one quite understands why nature should work this way, it seems that nature works by quantum mechanics (and entropy). The basic idea of quantum mechanics you will know that confined atoms can only occupy specific, quantized energy levels as shown below. The energy difference between the lowest energy state and the next level is typically high. Thus, most of the hydrogen atoms in an atom will occupy only the lower state, the so-called zero-point-energy state.

A hydrogen atom, shown occupying an interstitial position between metal atoms (above), is also occupying quantum states (below). The lowest state, ZPE is above the bottom of the well. Higher energy states are degenerate: they appear in pairs. The rate of diffusive motion is related to ∆E* and this degeneracy.

A hydrogen atom, shown occupying an interstitial position between metal atoms (above), is also occupying quantum states (below). The lowest state, ZPE is above the bottom of the well. Higher energy states are degenerate: they appear in pairs. The rate of diffusive motion is related to ∆E* and this degeneracy.

The fraction occupying a higher energy state is calculated as c*/c = exp (-∆E*/RT). where ∆E* is the molar energy difference between the higher energy state and the ground state, R is the gas constant and T is temperature. When thinking about diffusion it is worthwhile to note that this energy is likely temperature dependent. Thus ∆E* = ∆G* = ∆H* – T∆S* where asterisk indicates the key energy level where diffusion takes place — the activated state. If ∆E* is mostly elastic strain energy, we can assume that ∆S* is related to the temperature dependence of the elastic strain.

Thus,

∆S* = -∆E*/Y dY/dT

where Y is the Young’s modulus of elasticity of the metal. For hydrogen diffusion in metals, I find that ∆S* is typically small, while it is often typically significant for the diffusion of other atoms: carbon, nitrogen, oxygen, sulfur…

The rate of diffusion is now calculated assuming a three-dimensional drunkards walk where the step lengths are constant = a. Rayleigh showed that, for a simple cubic lattice, this becomes:

D = a2/6τ

a is the distance between interstitial sites and t is the average time for crossing. For hydrogen in a BCC metal like niobium or iron, D=

a2/9τ; for a FCC metal, like palladium or copper, it’s

a2/3τ. A nice way to think about τ, is to note that it is only at high-energy can a hydrogen atom cross from one interstitial site to another, and as we noted most hydrogen atoms will be at lower energies. Thus,

τ = ω c*/c = ω exp (-∆E*/RT)

where ω is the approach frequency, or the amount of time it takes to go from the left interstitial position to the right one. When I was doing my PhD (and still likely today) the standard approach of physics writers was to use a classical formulation for this time-scale based on the average speed of the interstitial. Thus, ω = 1/2a√(kT/m), and

τ = 1/2a√(kT/m) exp (-∆E*/RT).

In the above, m is the mass of the hydrogen atom, 1.66 x 10-24 g for protium, and twice that for deuterium, etc., a is the distance between interstitial sites, measured in cm, T is temperature, Kelvin, and k is the Boltzmann constant, 1.38 x 10-16 erg/°K. This formulation correctly predicts that heavier isotopes will diffuse slower than light isotopes, but it predicts incorrectly that, at all temperatures, the diffusivity of deuterium is 1/√2 that for protium, and that the diffusivity of tritium is 1/√3 that of protium. It also suggests that the activation energy of diffusion will not depend on isotope mass. I noticed that neither of these predictions is borne out by experiment, and came to wonder if it would not be more correct to assume ω represent the motion of the lattice, breathing, and not the motion of a highly activated hydrogen atom breaking through an immobile lattice. This thought is borne out by experimental diffusion data where you describe hydrogen diffusion as D = D° exp (-∆E*/RT).

You’ll notice from the above that D° hardly changes with isotope mass, in complete contradiction to the above classical model. Also note that ∆E* is very isotope dependent. This too is in contradiction to the classical formulation above. Further, to the extent that D° does change with isotope mass, D° gets larger for heavier mass hydrogen isotopes. I assume that small difference is the entropy effect of ∆E* mentioned above. There is no simple square-root of mass behavior in contrast to most of the books we had in grad school.

As for why ∆E* varies with isotope mass, I found that I could get a decent explanation of my observations if I assumed that the isotope dependence arose from the zero point energy. Heavier isotopes of hydrogen will have lower zero-point energies, and thus ∆E* will be higher for heavier isotopes of hydrogen. This seems like a far better approach than the semi-classical one, where ∆E* is isotope independent.

I will now go a bit further than I did in my PhD thesis. I’ll make the general assumption that the energy well is sinusoidal, or rather that it consists of two parabolas one opposite the other. The ZPE is easily calculated for parabolic energy surfaces (harmonic oscillators). I find that ZPE = h/aπ √(∆E/m) where m is the mass of the particular hydrogen atom, h is Plank’s constant, 6.63 x 10-27 erg-sec,  and ∆E is ∆E* + ZPE, the zero point energy. For my PhD thesis, I didn’t think to calculate ZPE and thus the isotope effect on the activation energy. I now see how I could have done it relatively easily e.g. by trial and error, and a quick estimate shows it would have worked nicely. Instead, for my PhD, Appendix 3, I only looked at D°, and found that the values of D° were consistent with the idea that ω is about 0.55 times the Debye frequency, ω ≈ .55 ωD. The slight tendency for D° to be larger for heavier isotopes was explained by the temperature dependence of the metal’s elasticity.

Two more comments based on the diagram I presented above. First, notice that there is middle split level of energies. This was an explanation I’d put forward for quantum tunneling atomic migration that some people had seen at energies below the activation energy. I don’t know if this observation was a reality or an optical illusion, but present I the energy picture so that you’ll have the beginnings of a description. The other thing I’d like to address is the question you may have had — why is there no zero-energy effect at the activated energy state. Such a zero energy difference would cancel the one at the ground state and leave you with no isotope effect on activation energy. The simple answer is that all the data showing the isotope effect on activation energy, table A3-2, was for BCC metals. BCC metals have an activation energy barrier, but it is not caused by physical squeezing between atoms, as for a FCC metal, but by a lack of electrons. In a BCC metal there is no physical squeezing, at the activated state so you’d expect to have no ZPE there. This is not be the case for FCC metals, like palladium, copper, or most stainless steels. For these metals there is a much smaller, on non-existent isotope effect on ∆E*.

Robert Buxbaum, June 21, 2018. I should probably try to answer the original question about solids and fluids, too: why solids appear solid, and fluids not. My answer has to do with quantum mechanics: Energies are quantized, and always have a ∆E* for motion. Solid materials are those where ω exp (-∆E*/RT) has unit of centuries. Thus, our ability to understand the world is based on the least understandable bit of physics.

Alkaline batteries have second lives

Most people assume that alkaline batteries are one-time only, throwaway items. Some have used rechargeable cells, but these are Ni-metal hydride, or Ni-Cads, expensive variants that have lower power densities than normal alkaline batteries, and almost impossible to find in stores. It would be nice to be able to recharge ordinary alkaline batteries, e.g. when a smoke alarm goes off in the middle of the night and you find you’re out, but people assume this is impossible. People assume incorrectly.

Modern alkaline batteries are highly efficient: more efficient than even a few years ago, and that always suggests reversibility. Unlike the acid batteries you learned about in highschool chemistry class (basic chemistry due to Volta) the chemistry of modern alkaline batteries is based on Edison’s alkaline car batteries. They have been tweaked to an extent that even the non-rechargeable versions can be recharged. I’ve found I can reliably recharge an ordinary alkaline cell, 9V, at least once using the crude means of a standard 12 V car battery charger by watching the amperage closely. It only took 10 minutes. I suspect I can get nine lives out of these batteries, but have not tried.

To do this experiment, I took a 9 V alkaline that had recently died, and finding I had no replacement, I attached it to a 6 Amp, 12 V, car battery charger that I had on hand. I would have preferred to use a 2 A charger and ideally a charger designed to output 9-10 V, but a 12 V charger is what I had available, and it worked. I only let it charge for 10 minutes because, at that amperage, I calculated that I’d recharged to the full 1 Amp-hr capacity. Since the new alkaline batteries only claimed 1 amp hr, I figured that more charge would likely do bad things, even perhaps cause the thing to blow up.  After 5 minutes, I found that the voltage had returned to normal and the battery worked fine with no bad effects, but went for the full 10 minutes. Perhaps stopping at 5 would have been safer.

I changed for 10 minutes (1/6 hour) because the battery claimed a capacity of 1 Amp-hour when new. My thought was 1 amp-hour = 1 Amp for 1 hour, = 6 Amps for 1/6 hour = ten minutes. That’s engineering math for you, the reason engineers earn so much. I figured that watching the recharge for ten minutes was less work and quicker than running to the store (20 minutes). I used this battery in my firm alarm, and have tested it twice since then to see that it works. After a few days in my fire alarm, I took it out and checked that the voltage was still 9 V, just like when the battery was new. Confirming experiments like this are a good idea. Another confirmation occurred when I overcooked some eggs and the alarm went off from the smoke.

If you want to experiment, you can try a 9V as I did, or try putting a 1.5 volt AA or AAA battery in a charger designed for rechargeables. Another thought is to see what happens when you overcharge. Keep safe: do this in a wood box outside at a distance, but I’d like to know how close I got to having an exploding energizer. Also, it would be worthwhile to try several charge/ discharge cycles to see how the energy content degrades. I expect you can get ~9 recharges with a “non-rechargeable” alkaline battery because the label says: “9 lives,” but even getting a second life from each battery is a significant savings. Try using a charger that’s made for rechargeables. One last experiment: If you’ve got a cell phone charger that works on a car battery, and you get the polarity right, you’ll find you can use a 9V alkaline to recharge your iPhone or Android. How do I know? I judged a science fair not long ago, and a 4th grader did this for her science fair project.
