New REB hydrogen generator for car fueling, etc.

One of my favorite invention ideas, one that I’ve tried to get the DoE to fund, is a membrane hydrogen generator where the waste gas is burnt to heat the reactor. The result should be exceptional efficiency, low-cost, low pollution, and less infrastructure needs. Having failed to interest the government, I’ve gone and built one on my own dime. That’s me on the left, with Shua Spirka, holding the new core module (reactor, boiler, purifier and purifier) sized for personal car fueling.

Me and Shua and our new hydrogen generator core

The core just arrived from the shop last week, now we have to pumps and heat exchangers. As with our current products, the hydrogen is generated from methanol water, and extracted 99.99999% pure by diffusion through a metal membrane. This core fit in a heat transfer pot (see lower right) and the pot sits on a burner for the waste gas. Control is tricky, but I think I’ve got it. If it all works like it’s supposed to, the combination should be 80-90% energy-efficient, delivering about 75 slpm, 9 kg per day. That’s the same output as our largest current electrically heated generators, with a much lower infrastructure cost. The output should be enough to fuel one hydrogen-powered automobile per day, or keep a small fleet of plug-in, hydrogen-hybrids running continuously.

Hydrogen automobiles have a lot of advantages over Tesla-type electric automobiles. I’ll tell you how the thing works as soon as we set it up and test it. Right now, we’ve got other customers and other products to make.

Robert Buxbaum, February 18, 2016. If someone could supply a good hydrogen compressor, and a good fuel cell, that would be most welcome. Someone who can supply that will be able to ride in a really excellent cart of the future at this year’s July 4th parade.

Alcohol and gasoline don’t mix in the cold

1 Reply

One of the worst ideas to come out of the Iowa caucuses, I thought, was Ted Cruz claiming he’d allow farmers to blend as much alcohol into their gasoline as they liked. While this may have sounded good in Iowa, and while it’s consistent with his non-regulation theme, it’s horribly bad engineering.

At low temperatures ethanol and gasoline are no longer quite miscible

Ethanol and gasoline are that miscible at temperatures below freezing, 0°C. The tendency is greater if the ethanol is wet or the gasoline contains benzenes

We add alcohol to gasoline, not to save money, mostly, but so that farmers will produce excess so we’ll have secure food for wartime or famine — or so I understand it. But the government only allows 10% alcohol in the blend because alcohol and gasoline don’t mix well when it’s cold. You may notice, even with the 10% mixture we use, that your car starts poorly on the coldest winter days. The engine turns over and almost catches, but dies. A major reason is that the alcohol separates from the rest of the gasoline. The concentrated alcohol layer screws up combustion because alcohol doesn’t burn all that well. With Cruz’s higher alcohol allowance, you’d get separation more often, at temperatures as high as 13°C (55°F) for a 65 mol percent mix, see chart at right. Things get worse yet if the gasoline gets wet, or contains benzene. Gasoline blending is complex stuff: something the average joe should not do.

Solubility of dry alcohol (ethanol) in gasoline. The solubility is worse at low temperature and if the gasoline is wet or aromatic.

Solubility of alcohol (ethanol) in gasoline; an extrapolation based on the data above.

To estimate the separation temperature of our normal, 10% alcohol-gasoline mix, I extended the data from the chart above using linear regression. From thermodynamics, I extrapolated ln-concentration vs 1/T, and found that a 10% by volume mix (5% mol fraction alcohol) will separate at about -40°F. Chances are, you won’t see that temperature this winter (and if you you do, try to find a gas mix that has no alcohol. Another thought, add hydrogen or other combustible gas to get the engine going.

Robert E. Buxbaum, February 10, 2016. Two more thoughts: 1) Thermodynamics is a beautiful subject to learn, and (2) Avoid people who stick to foolish consistency. Too much regulation is bad, as is too little: it’s a common pattern: The difference between a cure and a poison is often just the dose.

Comic colonialism I: How the US got Guam without a fight.

3 Replies

America is often criticized for land it acquired by war e.g. Guam in the Spanish-American War. Though Spanish were corrupt and incompetent, and had (it seems) sunk the USS Maine by accident, the idea is that conquest is bad. Well, for better or worse, here’s how the US acquired Guam in a comic bloodless non-battle that provides an example of God laughing as he protects children, fools, and the U.S. of A.

It’s mid June, 1898, the Spanish-American War has raged for two months, and Theodore Roosevelt is in Cuba. Four ships lead by the USS Charleston leave Hawaii on a secret mission with orders to be opened only at sea. Captain Glass of the Charleston find he is to try to take Guam and destroy its fortress before proceeding to the Philippines for the major battle of the war. Glass is informed that Guam Harbor is defended Spanish warships plus a thick-walled fort housing many heavy cannon. A land assault will face, he’s told, over 1000 fighting men, dug in, heavily armed, and thoroughly familiar with the terrain. As it happens, military intelligence had vastly overstated the challenge. There are only 56 soldiers on Guam, and Span has neglected to tell the garrison that there’s a war on.

USS Charleston

The USS Charleston, victor of the non-battle of Guam.

Expecting a fierce battle, our soldiers and naval gunners practice shooting at towed targets and get excellently proficient, or so Glass believes. Fortunately, he’s wrong. On June 20, 1898, The Charleston steams into Guam’s harbor and finds no resistance. The only major ship is a Japanese trader sitting at anchor. No shots are fired, and there is no apparent activity on shore. In some confusion, Captain Glass order that 13 shots be fired at the fort. As it happens, it’s a fortuitous number. Also fortuitous, is that all the shots miss. In complete ignorance, the folks on shore think it is a 13 gun salute: that the Charleston is here for an official, state visit.

Now, the normal response would be for folks on Guam to return the 13 gun salute. If they had, it would have likely begun a cycle of death and destruction. But God is the protector of fools, and the fortress is out of gunpowder. The Spanish send an officer to the Charleston to ask for gunpowder and apologize for not returning the salute. After what must have been a most uncomfortable parlé, it is agreed that our nations were at war; that the officer was now a captured prisoner; and that he is being released to request surrender.

Coins celebrating our colonial territories.

Coins celebrating our colonial territories. None have senators or congressmen. Only DC gets to vote for president, a result of the 23rd amendment, 1961.

As soon as he is sent off, captain Glass begins to worry: maybe this is a trap. Maybe the guns are now focussed on him and his men? Maybe he should resume fire on the fort! Right about then, a friendly whaleboat sails by flying the American flag. It’s captained by Francisco “Frank”Portusach-Martinez from Chicago, an old friend of an officer aboard the Charleston. Captain Portusach comes on board, shows his US bona-fides, and explains that it’s no trap, just ignorance. Taking his advice, Captain Glass lands with a small party, arrests all 56 soldiers without a fight, and raises the American flag. The Star Spangled Banner is played, and Glass doesn’t quite know what to do next. What would you do in his shoes?

Captain Henry Glass

Captain Henry Glass, man with a mustache.

Having no experience or other orders, Captain Glass appoints Portusach as the first US Governor of Guam, and leaves to join Dewey in the Philippines. He does not destroy the fort as he finds it in such poor repair that he can claim it’s already destroyed. And that’s how we got Guam. Credit to Captain Glass for not screwing things up or angering the locals needlessly. One hundred and eighteen years later, Guam is still a US territory, though there have been movements for statehood, for union with Hawaii, and for independence. Until the folks on Guam decide otherwise, they are US citizens, but can not vote for president or have representation in congress. They pay federal income taxes, but not state taxes. Bill Clinton is the only US president to ever visit Guam.

How to help Flint and avoid lead here.

Leave a reply

As most folks know, Flint has a lead-poisoning problem that seems to have begun in April, 2014 when the city switched its water supply from Detroit-supplied, Lake Huron water to their own source, water from the Flint River. Here are some thoughts on how to help the affected population, and how to avoid a repeat in Oakland county, where I’m running for water commissioner. First observation, it is not enough to make sure that the source water does not contain lead. The people who decided on the switch had found that the Flint river water had no significant content of lead or other obvious toxins. A key problem, it seems: the river water did not contain anticorrosion phosphates, and none, it seems, were added by the Flint water folks. It also seems that insufficient levels of chlorine (hypochlorite) were added. After the switch, citizens started seeing disgusting, brown water come from their taps, and citizens with lead pipes or solder were poisoned with ppb-levels of lead. There was also an outbreak of legionaries disease that killed 12 people. It was the legionaries that alerted the CDC to the possibility of lead, since it seems the water folks were fudging the numbers there, and hiding that part of the problem.

Flint water, Sept 2015, before switching back to Lake Huron.

Flint water after 5 hours of flushing, Sept 2015, before switching back to Lake Huron.

The city began solving its problem by switching back to Detroit-supplied, Lake Huron water in October, 2015. Beginning in December, 2015, they started adding triple doses of phosphate to the wate. As a result, Flint tap-water is now back within EPA standards, but it’s still fairly unsafe, see here for more details.

There has been a fair amount of finger-pointing. At Detroit for raising the price of water so Flint had to switch, at water officials ignoring the early signs of lead and fudging their reports, at other employees for not adding phosphate or enough chlorine, and at “the system” for not providing Flint’s government with better oversight. My take is that a lot of the problem came from the ignorance of the water commission, and it’s commissioner. We elect our water commissioners to be competent overseers of complex infrastructure, but in may counties folks seem to pick them the same way they pick aldermen: for a nice smile, a great handshake, and an ability to remember names. That, anyway, seems to be the way that Oakland got its current water commissioner. When you pick your commissioner that way, it’s no surprise that he (or she) isn’t particularly up on corrosion chemistry, something that few people understand, and fewer care about until it bites them.

Flint river water contains corrosive chloride that probably helped dissolve the lead from pipes and solder. Contributing to the corrosion problem, I’m going to guess that Flint River water also contains, relatively little carbonate, but significant amounts of chelating chemicals, like EDTA, in 10s of ppb concentration. EDTA isn’t poisonous at these concentrations, but it’s common in industry and is the most commonly used antidote for lead poisoning. EDTA extracts lead and other metals from people and would tend to contribute to the process of extracting lead and iron oxide from the pipes surface into the drinking water. With EDTA in the water, a lot of phosphate or hypochlorite would be needed to avoid the lead poisoning problem and the deadly multiplication of disease.

Detroit ex-mayor Kwame Kilpatrick has claimed that both Flint water and Detroit water were known to be poisoned even a decade before the switch. I find these claims believable given the high levels of lead in kids blood even before the switch. Also, I note that there are areas of Detroit where the blood-lead levels are higher than Flint. Flint tested at the taps in a way that fudged the data during the first days of the poisoning, and I suspect many of our MI cities do this today — just to make the numbers look better. My first suggestion therefore is to test correctly, both at the pipes and at the taps; lead pipes are most-often found in the last few feet before the tap. In particular, we should test at all schools and other places where the state has direct authorization to fix the problem. A MI senate bill has been proposed to this effect, but I’m not sure where it stands in the MI house. It seems there are movements to add lots of ‘riders’ and that’s usually a bad sign.

Another thought is that citizens should be encouraged to test their private taps and helped to fix them. The state can’t come in and test or rip out your private pipes, even if they suspect lead, but the private owner has that authorization. The state could condemn a private property where they believe the water is bad, but I doubt they could evict the residents. It’s a democratic republic, as I understand; you have the right to be deadly stupid. But I’ll take my own suggestion to encourage you: If you think your water has lead, take a sample and call (517) 335-8184. Do it.

Another suggestion, perhaps the easiest and most important, is drink bottled water for now, and if you feel you’ve been poisoned, take an antidote.  As I understand things, the state is already providing bottles of imported water. The most common antidote is, as I’d mentioned, EDTA. Assuming that Flint River water had enough EDTA to significantly worsen the problem, the cheapest antidote might be Flint River water, assuming you drew it in lead-free pipes and chlorinated sufficiently to rid it of bugs. If there is EDTA it will help the poisoned. Another antidote is Succinic acid, something sold by REB Research, my company. As with EDTA it is non-toxic, even in fairly large doses, but its use would have to be doctor- approved.

Robert E. Buxbaum, January 19-31, 2016. I hope this helps. We’d have to check Flint River water for levels of EDTA, but I suspect we’d find biologically significant concentrations. If you think Oakland should have an engineer in charge of the water, elect Buxbaum for water commissioner.

Abraham ROFLed; Sarah LOLed.

Something is lost, and something else gained when the Bible is translated into modern terms. Some grandeur is lost, some weight, but what is gained is a sense of intimacy, a personal relationship to the events and people.

Consider, for example, Abraham’s reaction when God reveals that he will have a son (Gen. 17:17). The King James translation is “Abraham fell facedown; he laughed and said to himself, “Will a son be born to a man a hundred years old? Will Sarah bear a child at the age of ninety?” There’s grandeur, but the event is distant from me.

Similarly, The Living Torah, “Then Abraham bowed down to the ground, but he laughed to himself in disbelief. ‘How could I become a father at the age of 100?’ he thought. ‘And how can Sarah have a baby when she is ninety years old?'”

I don’t find this translation relatable either. To me, it would be better to say that Abraham did the first ROTFL (Roll on the floor laughing): “Abraham ROFLed, how grand to have a son at 100 years…” It brings up a pleasant image: of Abraham as a man of red face and good humor, a hearty companion, and a good host. Someone you’d want to visit, not a stick-in-the-mud who you visit because he owns the last hotel on the road to Sodom.

Not totally the way I see it: Sarah looks stunned, but at least this captures a jolly Abraham.

Not totally the way I see it: Sarah looks stunned, but at least this captures a jolly Abraham.

And the same with Abraham’s wife, Sarah. Her home is full of dusty tourist guests, and she feeds them steak. Do you see a silent martyr, or a jolly sort who genuinely likes guests. This is important because we are to learn from these stories, Too often the doctors of the religion seem to want martyrs, but my read of Genesis is that sh’s jolly.. Sarah listens to the tales of her guests, and when one says she will have a child at 90, she LOLs (laughs out loud, Gen. 18:12) “So Sarah laughed to herself as she thought, ‘I’m old and my husband is too, will I have fun!” If God wants something weird Sarah is up for it. To her, it sounds like fun. And after that, “Will I nurse a child?!.”

I note that these are the paradigms of humanity, individuals that God loved, and spoke to at length. So lets do the same, be open to the positive, weird future, wherever God takes us. Let’s behave as God himself does. For, as we find Psalms (2:4), “He, who sits in the heavens, laughs; He mocks those who plan against HIm.” Now, ask the doctors of your religion, why are you so serious, when “He, who sits in the heavens, laughs”

Robert E. Buxbaum, January 12, 2016. This is my third essay on religion, all of them, I guess on the lighter side. In the first, I note that science and religion are opposites, In the follow-up, that secular philosophy and religion are uncomfortable competitors, and now that God likes the jolly (you probably prefer the jolly, too.)

The Hindenburg: mainly the skin burnt

4 Replies

The 1937 Hindenburg disaster is often mentioned as proof that hydrogen is too flammable and dangerous for commercial use. Well hydrogen is flammable, and while the Hindenburg was full of hydrogen when it started burning, but a look at a color photograph of the fire ( below), or at the B+W  Newsreel film of the fire, suggests that it is not the hydrogen burning, but the skin of the zeppelin and the fuel. Note the red color of the majority flame, and note the black smoke. Hydrogen fires are typically invisible or very light blue, and hydrogen fires produce no smoke.

Closeup of the Hindenburg burning. It is the skin and gasoline that burns, not the gaseous hydrogen.

The Hindenburg was not a simple hydrogen balloon either. It was a 15 story tall airship with state-rooms, a dining room and an observation deck. It carried 95 or so passengers and crew. There was plenty of stuff to burn besides hydrogen. Nor could you say that a simple spark had set things off. The Hindenburg crossed the ocean often: every 2 1/2 days. Lightning strikes were common, as were “Saint Elmo’s fire,” and static electricity discharges. And passengers smoked onboard. Holes and leaks in the skin were also common, both on the Hindenburg and on earlier airships. The hydrogen-filled, Graf Zeppelin logged over 1 million flight miles and over 500 trips with no fires. And it’s not like helium-filled zeppelins and blimps are much safer. The photo below shows the fire and crash of a helium-filled Goodyear blimp, “Spirit of Safety”, June, 2011. Hydrogen has such a very high thermal conductivity that it is nearly as hard to light as helium. I recently made this video where I insert a lit cigar into a balloon filled with hydrogen. There is no fire, but the cigar goes out.  In technical terms, hydrogen is said to have a low upper combustion limit.

Helium-filled goodyear blimp catches fire and burns to destruction.

Helium-filled goodyear blimp “spirit of safety” catches fire and burns before crashing. It’s not the helium burning.

The particular problem with the Hindenburg seems to have been its paint, skin and fuel, the same problems as caused the fire aboard the “Spirit of Safety.” The skin of the Hindenburg was cotton, coated with a resin-dope paint that contained particles of aluminum and iron-oxide to help conduct static electricity. This combination is very flammable, essentially rocket fuel, and the German paint company went on to make rocket fuel of a similar composition for the V2 rockets. And the fuel was flammable too: gasoline. The pictures of the Hindenburg disaster suggest (to me) that it is the paint and the underlying cotton skin that burned, or perhaps the fuel. A similar cause seems to have beset the “Spirit of Safety.” For the Hindenburg’s replacement, The Graf II, the paint composition was changed to replace the aluminum powder with graphite – bronze, a far less flammable mixture, and more electrically conductive. Sorry to say, there was no reasonably alternative to gasoline. To this day, much of sport ballooning is done with hydrogen; statistically it appears no more dangerous than hot air ballooning.

It is possible that the start of the fire was a splash of gasoline when the Hindenburg made a bumpy contact with the ground. Another possibility is sabotage, the cause in a popular movie (see here), or perhaps an electric spark. According to Aviation Week, gasoline spoiled on a hot surface was the cause of the “Spirit of Safety fire,” and the Hindenburg disaster looks suspiciously similar. If that’s the case, of course, the lesson of the Hindenburg disaster is reversed. For safety, use hydrogen, and avoid gasoline.

Dr. Robert E. Buxbaum, January 8, 2016. My company, REB Research, makes hydrogen generators, and other hydrogen equipment. If you need hydrogen for weather balloons, or sport ballooning, or for fuel cells, give us a call.

Advanced windmills + 20 years = field of junk

2 Replies

Everything wears out. This can be a comforting or a depressing thought, but it’s a truth. No old mistake, however egregious, lasts forever, and no bold advance avoids decay. At best, last year’s advance will pay for itself with interest, will wear out gracefully, and will be recalled fondly by aficionados after it’s replaced by something better. Water wheels, and early steamships are examples of this type of bold advance. Unfortunately, it is often the case that last years innovation turns out to be no advance at all: a technological dead end that never pays for itself, and becomes a dangerous, rotting eyesore or worse, a laughing-stock blot or a blot on the ecology. Our first two generations of advanced windmill farms seem to match this description; perhaps the next generation will be better, but here are some thoughts on lessons learned from the existing fields of rotting windmills.

The ancient design windmills of Don Quixote’s Spain (1300?) were boons. Farmers used them to grind grain or cut wood, and to to pump drinking water. Holland used similar early windmills to drain their land. So several American presidents came to believe advanced design windmills would be similar boons if used for continuous electric power generation. It didn’t work, and many of the problems could have been seen at the start. While the farmer didn’t care when his water was pumped, or when his wood is cut. When you’re generating electricity, there is a need to match the power demand exactly. Whenever the customer turns on the switch, electricity is expected to flow at the appropriate amount of Wattage; at other times any power generated is a waste or a nuisance. But electric generator-windmills do not produce power on demand, they produce power when the wind blows. The mismatch of wind and electric demand has bedeviled windmill reliability and economic return. It will likely continue to do so until we find a good way to store electric power cheaply. Until then windmills will not be able to produce electricity at competitive prices to compete with cheap coal and nuclear power.

There is also the problem of repair. The old windmills of Holland still turn a century later because they were relatively robust, and relatively easy to maintain. The modern windmills of the US stand much taller and move much faster. They are often hit, and damaged by lightning strikes, and their fast-turning gears tend to wear out fast, Once damaged, modern windmills are not readily fix, They are made of advanced fiberglass materials spun on special molds. Worse yet, they are constructed in mountainous, remote locations. Such blades can not be replaces by amateurs, and even the gears are not readily accessed to repair. More than half of the great power-windmills built in the last 35 years have worn out and are unlikely to ever get repair. Driving past, you see fields of them sitting idle; the ones still turning look like they will wear out soon. The companies that made and installed these behemoth are mostly out of the business, so there is no-one there to take them down even if there were an economic incentive to do so. Even where a company is found to fix the old windmills, no one would as there is not sufficient economic return — the electricity is worth less than the repair.

Komoa Wind Farm in Kona, Hawaii, June 2010; A field of modern design wind-turbines already ruined by wear, wind, and lightning. — Friends of Grand Ronde Valley.

A single rusting windmill would be bad enough, but modern wind turbines were put up as wind farms with nominal power production targeted to match the output of small coal-fired generators. These wind farms require a lot of area,  covering many square miles along some of the most beautiful mountain ranges and ridges — places chosen because the wind was strong

Putting up these massive farms of windmills lead to a situation where the government had pay for construction of the project, and often where the government provided the land. This, generous spending gives the taxpayer the risk, and often a political gain — generally to a contributor. But there is very little political gain in paying for the repair or removal of the windmills. And since the electricity value is less than the repair cost, the owners (friends of the politician) generally leave the broken hulks to sit and rot. Politicians don’t like to pay to fix their past mistakes as it undermines their next boondoggle, suggesting it will someday rust apart without ever paying for itself.

So what can be done. I wish I could suggest less arrogance and political corruption, but I see no way to achieve that, as the poet wrote about Ozymandias (Ramses II) and his disastrous building projects, the leader inevitably believes: “I am Ozymandias, king of kings; look on my works ye mighty and despair.” So I’ll propose some other, less ambitious ideas. For one, smaller demonstration projects closer to the customer. First see if a single windmill pays for itself, and only then build a second. Also, electricity storage is absolutely key. I think it is worthwhile to store excess wind power as hydrogen (hydrogen storage is far cheaper than batteries), and the thermodynamics are not bad

Robert E. Buxbaum, January 3, 2016. These comments are not entirely altruistic. I own a company that makes hydrogen generators and hydrogen purifiers. If the government were to take my suggestions I would benefit.

Cross of gold democrats

3 Replies

While it is dangerous to paint a large organization like the Democratic party with a single, broad brush, there are always patterns that appear, in this case in every presidential platform for a century. Beginning in the late 1800s when the Democratic party gave up on slavery, a stated goal of every Democratic platform has been to help the poor and downtrodden. Republicans claim to help too, but claim to target the worthy. For Democrats, by contrast, the common aim is to provide help without reference to individual worth or work — to help just because the individual needs it. All versions of this classic Democratic goal are achieved through forms of wealth redistribution: taking from the rich to give to the poor, Robin Hood style, at least temporarily. There is some inherent tension here: if the recipient can get free money without working, why would he work — a tension that some find insulting, but others accept as part of the comic nature of society. Many Americans accept that helping poor people is such a worthy goal that they knowingly accept the tension and cheating.

Mayor Quimba of Springfield (from the Simpsons). A classical Democrat, his motto: Corrupts in Extremus

Mayor Quimby of Springfield (from the Simpsons) is a classical Democrat, he has no morals beyond, ‘whatever the public wants’. Quimby is corrupt and an awful manager, but quite likable.

Extracting money from the rich always proves difficult: the rich generally object. The most direct way to extract money is taxation, but Democratic politicians, like Mayor Quimby, right try to shy from this to avoid being branded “tax and spend Democrats.” This year, Bernie Sanders has taken this line, proposing to raise the tax rate on the wealthy to 90% of income so he can do good for the poor and curb the power of rich Republicans. He has no problem with rich Democrats like Ms. Clinton, or perhaps he does, but doesn’t say so. In Britain, under Attlee, the tax rate was raised to 95%, a rate memorialized in The Beatles song “Taxman” (there one for you nineteen for me; 19/20 = 95%). Americans oscillate between accepting high tax rates and acknowledging that the worker and creative must be able to keep most of his/her earnings or he/she will stop working.

Every few years recipient Americans revolt against the way redistribution makes rich Democrats richer, and how high taxes seem to go with crony corruption. The motto of The Simpson’s Mayor Quimby is “corruptus in extremus”, a nod to the observation of how corruption in redistribution favors friends and family of those redistributing the wealth. Redistribution also tends to create poverty. This happened in England, for example. As Quimby says: “I propose that I use what’s left of the town treasury to move to a more prosperous town and run for mayor. And, er, once elected I’ll send for you.”

An alternative many Democrats favor is to print money or borrow it. This appears to be Ms Clinton’s approach, and was proposed famously in the “cross of gold” speech of William Jennings Brian in 1896.  In this speech, one of the finest in American history, Bryan (an unknown until then) proposed to monetize silver and other assets, allowing him to print money. He would spend the money on the poor by debasing the currency, that is by inflation. Bryan claimed that the rich were anyway sitting on unused money: a useless, dangerous pile that he’d inflate away. He also claimed that the poor are the ones who owe money, a burden that he would wipe out with inflation. Bryan’s final line is immortal: “you shall not press down on the people this crown of thorns, you shall not crucify the nation on a cross of gold.” The speech managed to combine God and greed and was an enormous success. Following the speech there was stunned silence, and then whoops and hollers. Bryan was carried around the convention for an hour before being chosen the Democratic candidate for president in 1896, 1900, and 1908. His speech has appeared, to a greater or lesser extent, in the platform of every Democratic candidate since with a greater or lesser reference to God depending on the conservatism of the speaker.

Republicans have traditionally supported property rights and harder money: gold in the old days, a balanced budget today. They claim that low inflation is good for the rich and poor alike, and especially for the small businessman. Entrepreneurs are pictured as more virtuous than the idle, wastrel Democrats. Free money, the Republicans note, discourages work. Of course, distinguishing worthy from wastrel is easier said than done. Republicans are accused of being uncharitable, and of helping the idle rich once they get into office. Presidential candidate, Donald Trump claimed that until now he’d give big donations to candidates of the left and right so they would repay the favor with interest at a later date. No one knows if it will change when he gets in office, but so far he’s avoided the major rich donors. He’s doing well running as a lovable, rich, jerk who’d do things different.

Inflation is a dangerous mistress, the middle class generally doesn’t like the way it wipes out debts and savings, while supporting a class of rich wastrels, drunks and the chronically unemployed. Many of the poor and middle class save, while the rich tend to build up debts. The rich have better credit ratings than the poor, and thus borrow more. They are also better positioned to increase their borrowing if they think inflation is coming. The money they borrow is invested in hard assets: land, homes, and businesses. When inflation slows, they can sell these assets. And if they pick wrong, the government bails them out!. William Jennings Bryan lost all three of his runs at the presidency, twice to McKinley and once to William H. Taft, who stood for doing nothing.

William Jennings Bryan: for inflation and silver; against alcohol. Lost twice to McKinley and gold.

I think the American people want a balance in all things. They want a balance between helping everyone, and helping only the deserving; between high taxes to help folks, and allowing folks to keep their wealth. They don’t quite know where to draw the line, and will even help the wastrels, even those who refuse to work, because they don’t want them starving in the street. They also seem to accept rich folks getting richer, especially when a big project is needed — a ship or a bridge, for example. We elect an alternating mix of Democrats and Republicans; conservatives, and liberals to avoid false paradoxes, achieve some liberty, and establish one of the richest states known.

As for me, you might as well know, I’m a liberal Republican. I favor low income taxes, but some welfare; taxing imports (tariffs), and low inflation –“bread currency,” I like Peter Cooper, and the Greenback Party, 1876. Cooper claimed that the dollar should always have the same value “for the same reason that the foot should always have 12 inches and the pound 16 ounces.” I also think enforcing morality is a job for preachers, not politicians. For 160 years students of Peter Cooper’s union were getting a free college education and I’m one of those engineering students, see my biography of Peter Cooper.

Highest temperature superconductor so far: H2S

Leave a reply

The new champion of high-temperature superconductivity is a fairly common gas, hydrogen sulphide, H2S. By compressing it to 150 GPa, 1.5 million atm., a team lead by Alexander Drozdov and M. Eremets of the Max Planck Institute coaxed superconductivity from H2S at temperatures as high as 203.5°K (-70°C). This is, by far, the warmest temperature of any superconductor discovered to-date, and it’s main significance is to open the door for finding superconductivity in other, related hydrogen compounds — ideally at warmer temperatures and/or less-difficult pressures. Among the interesting compounds that will certainly get more attention: PH3, BH3, Methyl mercaptan, and even water, either alone or in combination with H2S.

Relationship between H2S pressure and critical temperature for superconductivity.

H2S superconductivity appears to follow the standard, Bardeen–Cooper–Schrieffer theory (B-C-S). According to this theory superconductivity derives from the formation of pairs of opposite-spinning electrons (Cooper pairs) particularly in light, stiff, semiconductor materials. The light, positively charged lattice quickly moves inward to follow the motion of the electrons, see figure below. This synchronicity of motion is posited to create an effective bond between the electrons, enough to counter the natural repulsion, and allows the the pairs to condense to a low-energy quantum state where they behave as if they were very large and very spread out. In this large, spread out state, they slide through the lattice without interacting with the atoms or the few local vibrations and unpaired electrons found at low temperatures. From this theory, we would expect to find the highest temperature superconductivity in the lightest lattice, materials like ice, boron hydride, magnesium hydride, or H2S, and we expect to find higher temperature behavior in the hydrogen version, H2O, or H2S than in the heavier, deuterium analogs, D2O or D2S. Experiments with H2S and D2S (shown at right) confirm this expectation suggesting that H2S superconductivity is of the B-C-S type. Sorry to say, water has not shown any comparable superconductivity in experiments to date.

We have found high temperature superconductivity in few of materials that we would expect from B-C-S theory, and yet-higher temperature is seen in many unexpected materials. While hydride materials generally do become superconducting, they mostly do so only at low temperatures. The highest temperature semiconductor B-C-S semiconductor discovered until now was magnesium boride, Tc = 27 K. More bothersome, the most-used superconductor, Nb-Sn, and the world record holder until now, copper-oxide ceramics, Tc = 133 K at ambient pressure; 164 K at 35 GPa (350,000 atm) were not B-C-S. There is no version of B-C-S theory to explain why these materials behave as well as they do, or why pressure effects Tc in them. Pressure effects Tc in B-C-S materials by raising the energy of small-scale vibrations that would be necessary to break the pairs. Why should pressure effect copper ceramics? No one knows.

The standard theory of superconductivity relies on Cooper pairs of electrons held together by lattice elasticity. The lighter and stiffer the lattice, the higher temperature the superconductivity.

The assumption is that high-pressure H2S acts as a sort of metallic hydrogen. From B-C-S theory, metallic hydrogen was predicted to be a room-temperature superconductor because the material would likely to be a semi-metal, and thus a semiconductor at all temperatures. Hydrogen’s low atomic weight would mean that there would be no significant localized vibrations even at room temperature, suggesting room temperature superconductivity. Sorry to say, we have yet to reach the astronomical pressures necessary to make metallic hydrogen, so we don’t know if this prediction is true. But now it seems H2S behaves nearly the same without requiring the extremely high pressures. It is thought that high temperature H2S superconductivity occurs because H2S somewhat decomposes to H3S and S, and that the H3S provides a metallic-hydrogen-like operative lattice. The sulfur, it’s thought, just goes along for the ride. If this is the explanation, we might hope to find the same behaviors in water or phosphine, PH3, perhaps when mixed with H2S.

One last issue, I guess, is what is this high temperature superconductivity good for. As far as H2S superconductivity goes, the simple answer is that it’s probably good for nothing. The pressures are too high. In general though, high temperature superconductors like NbSn are important. They have been valuable for making high strength magnets, and for prosaic applications like long distance power transmission. The big magnets are used for submarine hunting, nuclear fusion, and (potentially) for levitation trains. See my essay on Fusion here, it’s what I did my PhD on — in chemical engineering, and levitation trains, potentially, will revolutionize transport.

State bird suggestion: the turkey

2 Replies
state bird stamps; robin cardinal

three US states use the (american) robin as their state bird, and 7 more use the (northern) cardinal. None use the turkey

As things now stand, three states of the union, including Michigan have the robin as their state bird. Another seven have the cardinal. Not that they have different species of robin or cardinal, they use the same species: the American robin, and the Northern cardinal respectively.

A thought I’ve had is that Michigan should change to have a unique bird symbol, and I propose the turkey, in particular the eastern wild turkey shown below. The robin is found in every state of the union except for Hawaii, and is found in several countries, it’s associated with Robin Hood, and with Batman’s side-kick. By contrast, the eastern wild turkey could be a unique state symbol. It’s basically found in no other country besides the US, and found in only a few US states including Michigan.

Eastern Wild Turkey. A majestic bird, and brave Maximum height: 4 foot.

Eastern Wild Turkey. A majestic bird, and brave. Maximum height: 4 foot.

The eastern wild turkey is a far more impressive bird than the cardinal or robin. Full grown, it stands 4 foot tall. Benjamin Franklin claimed to have preferred the turkey (likely the eastern wild turkey) to the eagle as the national bird of the US. In this wonderful letter to his daughter, Sarah, he says that it is a noble bird, useful and the source of sustenance. He also claims it is unafraid to attack a British regimen, claims that also appears in this song, “the egg” in the play/movie 1776. The turkey most definitely provided food for the Indians, for the early European settlers, and still provides for Michigan hunters to this day. Further, turkey feathers are the preferred choice for quill pens. They are used for scribes writing holy works, like copies of the Torah, and it is likely they were used for the declaration of Independence. The same history and associations can not be claimed for the robins or the cardinal. Those birds are basically attractive, and nothing else.

Not that attractive is bad, nor is it bd to have a state bird associated with Batman’s side-kick, or with a Saint Louis baseball team, but I don’t think either is particularly appropriate for Michigan. Not that there are no disadvantages to the name turkey: (1) it might suggest a slow individual or project, and (2) Wild Turkey is the name of a Tennessee bourbon whiskey. Neither of these are quite a bad as being a sidekick to the bat, or to the batman, and I think both are addressed by specifying that the state bird is the eastern wild turkey, and not just some random variety. What say ye, citizens of Michigan? Let’s do it before someone else takes the turkey.
