Ferries make more sense than fast new trains.

Per pound mile of material, the transport cost by ship is 1/4 as much as by train, and about 1/8 as much as by truck. Ships are slower, it is true, but they can go where trucks and trains can not. They cross rivers and lakes at ease and can haul weighty freight with ease. I think America could use many more ferries, particularly drive-on, fast ferries. I don’t think we need new fast rail lines, because air travel will always be faster and cheaper. The Biden administration thinks otherwise, and spends accordingly.

Amtrak gets $30 Billion for train infrastructure this year, basically nothing for ferries.

The Biden administration’s infrastructure bill, $1.2 Trillion dollars total, provides $30 Billion this year for new train lines, but includes less than 1% as much for ferries, $220 million, plus $1B for air travel. I think it’s a scandal. The new, fast train lines are shown on the map, above. Among them is a speed upgrade to the “Empire Builder” train running between Chicago and Seattle by way of Milwaukee. I don’t think this will pay off — the few people who take this train, takes it for the scenery, I think, and for the experience, not to get somewhere fast.

There is money for a new line between Cleveland and Detroit, and for completion of the long-delayed, and cost-over-run prone line between LA and San Francisco. Assuming these are built, I expect even lower ridership since the scenery isn’t that great. Even assuming no delays (and there are always delays), 110 mph is vastly slower than flying, and typically more expensive and inconvenient. Driving is yet slower, but when you drive, you arrive with your car. With a train or plane, you need car rental, typically.

New Acela train, 150 mph max. 1/4 as fast as flying at the same price.

Drive-on ferries provide a unique advantage in that you get there with your car, often much faster than you would with by driving or by train. Consider Muskegon to Milwaukee (across the lake), or Muskegon to Chicago to Milwaukee, (along the lake). Cleveland to Canada, or Detroit to Cleveland. No land would have to be purchased and no new track would have to be laid and maintained. You’d arrive, rested and fed (they typically sell food on a ferry), with your car.

There’s a wonderful song, “City of New Orleans”, sung here by Arlo Guthrie describing a ride on the historic train of that name on a trip from Chicago to New Orleans, 934 miles in about one day. Including stops but not including delays, the average speed is 48 mph, and there are always delays. On board are, according to the song, “15 restless riders, 3 conductors, and 25 sacks of mail.” The ticket price currently is $200, one way, or about as much as a plane ticket. The line loses money. I’ve argued, here, for more mail use to hep make this profitable, but the trip isn’t that attractive as a way to get somewhere, it’s more of a land-cruise. The line is scheduled for an upgrade this year, but even if upgraded to 100 mph (14 hours to New Orleans including stops?) it’s still going to be far slower than air travel, and likely more expensive, and you still have to park your car before you get on, and then rent another when you get off. And will riders like it more? I doubt it, and doubt the speed upgrade will be to 100 mph.

Lake Express, 30 mph across Lake Michigan

Ferry travel tends to cost less than train or plane travel because water traffic is high volume per trip with few conductors per passenger. At present, there are only two ferryboats traveling across Lake Michigan, between Michigan and Wisconsin, Milwaulkee to Muskegon. They are privately owned, and presumably make money. The faster is the Lake Express, 30 mph. It crosses the lake in 2.5 hours. Passenger tickets cost $52 one way, or $118 for passenger and car. That’s less than the price of an Amtrak ticket or a flight. I think a third boat would make sense and that more lines would be welcome too. Perhaps Grand Haven to Racine or Chicago.

Route of the Lake Express. I’d like to see more like this; St. Joseph to Milwaukee say, and along Lake Erie.

Currently, there are no ferries across Lake Erie. Nor are there any along Lake Erie, or even across Lake St. Clair, or along the Detroit River, Detroit to Toledo or Toledo to Cleveland. These lines would need dock facilities, but they would have ridership, I think. New York’s Staten Island ferry has good ridership, 35,000 riders on a typical day, plus cars and trucks. In charge are roughly 120 engineers, captains and mates, one employee for every 300 passengers or so. By comparison, Amtrak runs 300 trains that carry a total of 87,000 passengers on an average day, mostly on the east coast. These 300 trains are run by 17,100 employees as of fiscal year 2021, one employee for every 4 passengers. Even at the slow speeds of our trains the cost is far higher per passenger and per passenger mile.

The Staten Island ferry is slow, 18.5 mph, but folks don’t seem to mind. The trip takes 20 minutes, about half as long as most people’s trips on Amtrak. There are also private ferry lines in NY, many of these on longer trips. People would take ferries for day-long trips along our rivers, I think. Fast ferries would be nice, 40 mph or more, but I think even slow ferries would have ridership and would make money. A sea cruise is better than a land cruise, especially if you can have a cabin. On the coal-steam powered, Badger, you can rent a state-room to spend the night in comfort. Truckers seem to like that they cover ground during their mandatory rest hours. The advantage is maximized, I think, for ferry trips that take 12 hours or so, 250 to 350 miles. That’s Pittsburgh to Cincinnatti or Chicago to Memphis.

New York’s Staten Island ferry leaves every 15 minutes during rush hour. Three different sizes of boat are used. The largest carry over 5000 passengers and 100 cars and trucks at a crossing.

A low risk way to promote ferry traffic between the US and Canada would be to negotiate bilateral exemption to The Jones Act and its Canadian equivalent. Currently, we allow only US ships with US crews for US travel within the US.* Cabotage it’s called, and it applies to planes as well, with exemptions. Canada has similar laws and exemptions. A sensible agreement would allow in-country and cross-country travel on both Canadian and US ships, with Canadian and/or US crew. In one stoke, ridership would double, and many lines would be profitable.

Politicians of a certain stripe support trains because they look futuristic and allow money to go to friends. Europeans brag of their fast trains, but they all lose money, and Europe had to ban many short hop flights to help their trains compete. Without this, Europeans would fly. There is room to help a friend with a new ferry, but not as much as when you buy land and lay track. We could try to lead in fancy ferries going 40 mph or faster, providing good docks, and some insurance. Investors would take little risk since a ferry route can be moved**. Don’t try that with a train.

In Detroit we have a close up of train mismanagement involving the “People Mover.” It has no ridership to speak of. Our politicians then added “The Q line” to connect to it. People avoid both lines. I think people would use a ferry along the Detroit river, though, St. Claire to Wyandotte, Detroit, Toledo — and to Cleveland or Buffalo. Our lakes and rivers are near-empty superhighways. Let’s use them.

Robert Buxbaum, January 2, 2024. *The US air cabotage act (49 U.S.C. 41703) prohibits the transportation of persons, property, or mail for compensation or hire between points of the U.S. in a foreign civil aircraft. We’ve managed exemptions, though, e.g. for US air traffic with Airbus and Embraer planes. We can do the same with ferries.

** I notice that it was New York’s ferries, and their captains, that rescued the people on Sullenberger’s plane when it went down in the Hudson River — added Jan. 6.

The UAW’s minimally-effective strike.

The aim of a strike, generally, is the same as the aim of war: it is to win concessions fast. To do this, one must strike to the utmost extent, as Von Clausewitz points out. The target company must come to understand that they need the workers, and that they need a quick settlement. In the case of the current united auto worker strike, the UAW asked for 40% and concessions, but only struck at a few plants. The resulting strike lasted 6 weeks, with Ford settling for a 25% raise over 4.5 years, to April 2028. Viewed on an average, that’s a 5.6% raise per year, assuming the Ford workers accept the deal.

I’m not sure how the UAW boss chose which plants to strike AGAINST. They were mostly low-profit ones at first. Workers at other plants kept on working and received a full salary. The suffering was borne some 45,000 UAW workers (1/4 of the UAW autoworkers) who left the job for strike pay, $500/week. This is a tiny fraction of the 4.36 million auto workers in the US. Auto production was reduced by 80,000 vehicles, we’re told, again a small fraction of several million vehicles typically made in the US in a year.

The strike does not seem to have affected vehicle sales or profits, as best I can tell. The remaining plants ran at higher capacity, and some production was made up by imports from Canada, Mexico, and China. Inventories today are at 60 days, the industry target. In a sense, the major lessons of the strike are that the auto companies don’t need so many workers, and that the UAW can direct suffering to whichever workers they wish.

The gasoline-powered F-150, left, is the most popular vehicle in the US. The Tesla Cybertruck, right, is an EV challenger of a sort that will soon be mandated. EVs require fewer workers and manufacture is non-union.

Ford’s settlement sounds good, but if viewed as a 5.6% raise per year, it barely covers inflation. Inflation is 3.6% now and was 8% last year. Ford retained the right to shed workers and close plants as the economy slows or production shifts. That’s a minimal gain for a 4.5 year commitment.

Battery plants may be covered or not; we’ve not been told. Production is expected to shift to battery vehicles, and these require fewer workers per car. President Biden has mandated a shift as part of his plan to stop global warming (a plan that I find misguided). He’s provided financial incentives for EV owners too, under the “inflation reduction act,” an effort to cause consumers to buy cars they would not otherwise. Largesse of this type is problematic, and highly inflationary, at least in the short term (the next few years). It is supposed to help out down the road, but workers pay their bills in the short term, the here and now.

Despite Biden’s financial incentives to buy electric, most consumers prefer to buy gasoline. The gasoline F150 is the most popular vehicle in America, selling over 600,000 per year. Trump claims that US workers would be better off if we stopped pushing EVs. Less incentives means less inflation, more internal combustion cars, and more union jobs he says. Biden has recently funded a Chinese battery plant, non-union in Michigan, suggesting that Trump is on to something. The strike has produced a raise, but its main contribution, it seems was to punish those UAW workers that the union boss didn’t like.

Robert Buxbaum, October 29, 2023. As I write, Stellantis has offered a tentative deal, but GM is still holding out, and we’ve yet to see if the workers ratify any of these deals.

Rain barrels aren’t much good. Wood chips are better, And I’d avoid rain gardens, even as a neighbor.

A lot of cities push rain barrels as a way to save water and reduce flooding. Our water comes from the Detroit and returns to it as sewage, so I’m not sure there is any water saving, but there is a small cash saving (very small) if you buy 30 to 55 gallon barrels from the city and connect them to the end of your drain spout. The rainwater you collect won’t be pure enough to drink, or safe for bathing, but you can use it to water your lawn and garden. This sounds OK, even patriotic, until you do the math, or the plumbing, or until you consider the wood-chip alternative.

The barrels are not cheap, even when subsidized they cost about $100 each. Add to this the cost and difficulty of setting up the collection system and the distribution hose. Water from your rain barrel will not flow through a normal nozzle as there is hardly any pressure. Expect watering to take a lot longer than you are used to.

40 gallon rain barrels. Two of these give about 70 usable gallons every heavy rain fall. That’s about 70¢ worth.

In Michigan you can not leave the water in your barrel over the winter, the water will freeze and the barrel will crack. You have to drain the tank completely every fall, an almost impossible task, and the tank is attached to a rainspout and the last bit of water is hard to get out. Still, you have to do it, or the barrel will crack. And the savings for all this is minimal. During a rainy month, you don’t need this water. During a dry month, there is no water to use. Even at the best, the The marginal cost of water in our town is less than 1¢ per gallon. For all the work and cost to set up, two complete 40 gallon tanks (like those shown) will give you at most about 70 usable gallons. That’s to say, almost 70¢ per full filling.

How much lawn can you water? Assume you like to water your lawn to the equivalent of 1″ of rain per week, your 70 gallons will water about 154 ft2 of lawn or garden, virtually nothing compared to the typical Michigan 2000 ft2 lawn. You’ll still have to get most of your water from the city’s main. All that work, for so little benefit.

Young trees with chip volcanos, 1 ft high x18″. Spread the chips to the diameter of the leaves.You don’t need more than 2″.

A far better option is wood chips. They don’t cover a lawn, but they’re great for shrubs, trees or a garden. Wood chips are easy to spread, and they stop weeds and hold water. The photo at left shows a wood chips around the shrubs, and a particularly poor use of wood chips around the trees. For shrubs, trees, or a garden, I suggest you put down 1 to 2 inches of wood chips. Surround a young tree at that depth to the diameter of the branches. Do not build a “chip volcano,” as this lazy landscaper has done.

Consider that, covering 500 ft2 of area to a depth of 1.5 inches will take about 60 cubic feet of wood chips. That will cost about $35 dollars at the local Home Depot. This is enough to hold about 1.25″ or rainwater, That’s about 100 ft3 or water or 800 gallons. The chips prevent excess evaporation while preventing weeds and slowly releasing the water to your garden. You do no work. The chips take almost no work to spread, and will keep on working for years, with no fear of frost-damage. A as the chips stop working, they biocompost slowly into fertilizer. That’s a win.

There is a worst option too, called a rain garden. This is often pushed by environmental-gooders. You dig a hole near your downspout, perhaps ten feet in diameter, by two feet deep, and plant native grasses (weeds). When it rains, the hole fills with water creating a mini wetland that will soon smell like the swamp that it is. If you are not lucky, the water will find a way to leak into your basement. If that’s your problem look here. If you are luckier, your mini-swamp will become the home of mosquitos, frogs, and snakes. The plants will grow, then die, and rot, and look awful. It is very hard to maintain native grasses. That’s why people drain swamps and grow trees or turf or vegetables. If you want to see a well-maintained rain garden, they have two on the campus of Lawrence Tech. A wetland isn’t bad, but you want drainage, Make a bioswale or muir.

Robert Buxbaum, May 31, 2023. I ran for water commissioner some years back.

Right to work is a right.

In 26 states you can work in a unionized industry without joining a union. You can even cross a union strike line if you like. It’s called “right to work.” Michigan allowed it up till last month, but no longer. Immediately following the Democrats’ taking majority of the MI legislature, they voted to make non-union membership illegal. The claim was that those who do not want to be represented by the state-acknowledged union is misguided, or worse.

The argument for making union membership mandatory is presented in the poster at right. It notes that states that banned right to work are richer, with workers getting higher pay and benefits. These include California, New York, NJ, Washington, Alaska,.. See the map below. Although these states, on average have higher yearly wages, they also have higher taxes, higher costs of living, and more high-tech jobs. The cause and effect implied by this poster is erroneous, I think: The claim is that if you are forced to join a union you will be paid more with more benefits. I strongly suspect that the reality is that these states have high wages and high benefits and a lot of people working in safe fields, programming for example. They then force workers to work for one union so they’ll be easier managed, not because they want a strong opposition.

Another thing, even if you could guarantee higher wages by forced union membership, and you could avoid the high taxes and high cost of living that you find in NY and California, no person should be forced to accept representation by a group that they don’t get to choose, or who supports social goals that the worker doesn’t support. I don’t believe this is fair, or moral, but that’s how it is. It’s the law in most every state with a Democrat as governor and where Democrats control the legislature.

Right to work as of last month, before Michigan forced unionism.

Union membership had been declining in Michigan for years, but it took a particular nose dive in 2016 when the unions spent heavily for Clinton while blue collar workers supported Trump. It was 14% or workers before the law changed. Workers claimed that their unions were working against them, and complained about how their dues were spent. It also came out that some of the Michigan union bosses had stolen money from their funds to build fancy private houses — using non-union labor to do it. When the union bosses tried to show their muscle by calling strikes, the strikes accomplished little, or went on for months. The results were two-tier salaries, layoffs, and business failures. The working for the local newspapers teamsters struck, and one newspaper collapsed. The other chose non-union drivers. The teamsters are still on strike, 10 years later. I’d think a worker should be able to leave a union like this.

I’m a fan of unions, but think the worker should be able to choose. I’m a particular fan of craft unions that work to improve the quality of their work along with the quality of their workers lives. This helps everyone. I suspect that unions should not be able to support political parties too. See my thoughts on unions, here.

Michigan has a particularly strong history of crooked union bosses. When Jimmy Hoffa challenged the Teamster bosses over how the retirement fund was spent, he vanished. The union’s bosses seem to have had him killed. The last place where he was seen alive is an Andiamo Restaurant near my home. He was picked up by someone he knew, perhaps his nephew. No one’s talking and his remains were never found. In Michigan you used to be able to choose your union just as you chose your political club and your own lawyer, or you could choose none at all. Nowadays, the law says otherwise. Maybe you don’t like this law. Maybe you don’t like the union boss or how he’s spending. Maybe you’d like to visit with Jimmy Hoffa.

Robert Buxbaum May 19, 2023. Aside from everything else, you have a right to have a state that isn’t high-wage, high-tax, even if you could prove people were happier in such states. Freedom is a good, in and of itself.

Abortion and Childbirth in the US vs China

There are a lot of abortions in China, and not many births. Last year, there were about 9.7 million abortions in the major clinics and almost 12 million live births. That’s about 8.5 live births per 1000 Chinese population and 79.7 abortions per 100 live births. If you include the minor clinics and the abortion pill, it’s likely that there are more abortions than live births in China. It’s the preferred method of birth control. In the US, the ratio of abortions to births has grown but we have only about 1/4 as many abortions as births.

Births and abortions per year in China to 2020, from The Economist, 2023. The biggest change is decreased births, not increased abortions.

The birthrate in China is low and decreasing. China had pushed for one-child families as a cure for overpopulation and a route to a richer China with abortion promoted as a safe, painless way to end an unwanted pregnancy. Billboard ads continue to show happy women who are leading their best life now that they’ve had an abortion. Of course, during the one-child years, if you had that extra baby, the state might take your baby him or her. Condom ads were forbidden, and remain so to this day.

China seems to have succeeded too well. The population has leveled out, and has began to decline this year — likely too fast. Meanwhile the economy has grown by an average of 10% per year for 40 years, so that China is now, likely the second largest economy on the planet, but has such an old population that this is unlikely to continue. One down-side of the heavy reliance on abortion is that it’s produced a severe sex imbalance. The Chinese chose to abort mostly girls. It’s also resulted in an active sex trade. I’ve claimed it will lead to war, famine, or an economic collapse in the next ten years.

Add for a Chinese abortion clinic. See how happy the lady is. Chinese ads have English because it’s cool — it suggests that this clinic serves Americans and British too.

In the US, there were 3,664,000 births in 2022, 12.012 births per 1000 people. That’s 1.5 times the birth rate of China, and a 1% increase from 2020, but significantly below the birthrate of the boomer generation. In the last year, there were 928,000 abortions, see graph below, or 25.3 abortions per 100 live births. Our population is as old as China’s, but the additional children suggests that our society will continue longer.

In America, the case for abortion is that it’s a woman’s right, see ad below. Anti-abortion is presented as slavery and a Republican plot for male domination. Politically, this has been a winning argument for Democrats; helping them win big in elections. They made good on the argument and amended the Michigan constitution to allow abortion till birth with the father having no say. The legal and religious establishment has gone along. They may want some limitations, but there is no consensus on what the limitation should be.

Abortions per year, US, Guttmacher Inst. report, 2022.

It’s been suggested that a good way to lower the abortion rate would be higher taxes to provide more healthcare and child benefits. That may be, though I’m not sure it’s the direct, sure route. China has free healthcare and benefits. I suspect that the preachers should do more personally to deal with the vulnerable. Another thought is to promote is rural living. In the US and China, rural areas have higher birth rates, while the cities have low birth rates and high abortion rates. The highest abortion rate in the US is in Washington DC.

In the US, abortion is presented as a right, and as a Republican anti-woman plot.

My overall sense is that Children are good: Admittedly, they are expensive hobbies, but they are worth it, for the parents, for the nation, and in particular for the child. Children are a beautiful part of life and a beautiful part of any environment, IMHO. They like to grow amid sunshine and fresh air.

Our Jail Minimums are Huge, or non-existent

The United States has more people in prison, per-capita, than any other developed nation, see graph below. Our rate is double Russia’s, and barely below Cuba’s. About 38% of our prisoners are black. That’s a sign of cultural differences or systemic racism; perhaps both.

A major reason for our high prison rate is our huge minimum sentences. In Michigan, as most states, if you possess a firearm when committing a felony or an attempted felony, two years minimum are added to your sentence. The judge’s only allowed input is to add time, or to drop the felony charge. By law, two years minimum have to be added before (not during) the sentence for the underlying felony. It increases to 5 years minimum if you have a prior conviction, and 10 years if you have two or more prior convictions – on top of whatever the Judge decides for the crime. Typically, for a repeat offender, the judge will sentence zero for the felony, because 10 years is enough. Or he will drop the felony charge. The standard penalty, is either the huge minimum, or zero. About 25% of those in Michigan prison, are serving this minimum. Many others who should have gotten a month, or a year, were let go with nothing to avoid giving the minimum -crazy.

Countries with the highest prison population per 100,000 as of January 2023 (from statistica). No country in Europe makes this chart, Russia included.

These laws are specific to guns. No other deadly weapon is treated this way. A knife assailant serves the sentence for the assault only with adding 2 to 10 years minimum. We could go a long way to reduce the prison population if this add-on were moved or severely shortened. I’d like it shortened to 3 months, and broadened to all deadly weapons.

Minimums serve a purpose, I think, preventing violent felons from going free with a good sob-story. But our minimums too long to prevent crime and now only prevent rehabilitation. After ten years in prison, released felons have no life to return to, and no family. The only life they have is crime. It’s been speculated that our huge minimums make felons more violent. Saint Thomas Moore theorized this in the 1500s: A criminal facing a long prison sentence might as well kill the witnesses and hope to escape.

The Michigan State shooter,who killed 3 last week was a felon whose charge was dropped to avoid sending a mentally unstable black man to prison for 2 years. Anthony McRae, had a history as “a hell-raiser,” and was known to be mentally unstable. He had been shooting his gun outdoors near his home, and upon arrest was in possession of a concealed, loaded gun with no permit. These could be changed as firearm felonies, punished by 2 years minimum, or the Judge could drop the case, leaving McRae with his gun. The judge dropped the case, and returned the gun. McRae went on to kill with it. If the minimum were lower, 3 months say, I believe the judge would have convicted Mr McRae’s to that minimum, and taken his gun.

As it was, the judge was faced with the choice of ordering 2 years or nothing.

Our drug sentencing minimums are too high too, especially for “bad drugs.” These carry a 5 to 10 year minimum sentence with no chance for parole. But “dad drugs” are often the ones black people take: LSD, Crack, Heroin, and Methamphetamine. The drugs white politicians take are treated leniently, e.g. mayor Ford of Toronto, or Hunter Biden. I think we’d do everyone a favor by reducing drug minimums, even for bad drugs; for this, too, 2-3 month minimums should do with the judge having discretion to add.

There should be a maximum sentence too, I think, to stop hanging judges. And there should be rehabilitation, but it’s not clear we can manage that. The unions have opposed work-rehabilitation, calling it slave labor. Leader Dogs for the Blind allow prisoners to train guide dogs; it does wonderfully, but something bigger is needed. Lacking good rehabilitation, the smallest sentence that serves as a deterrent is what we should aim for.

Robert Buxbaum February 22, 2023. The original design of Sing-sing included work-rehabilitation in many crafts. The unions complained, and rehabilitation was stopped. Sentencing is a tough balancing act.

My home-made brandy and still.

MY home-made still, and messy lab. Note the masking tape seal and the nylon hoses. Nylon is cheaper than copper. The yellow item behind the burner is the cooling water circulation pump. The wire at top and left is the thermocouple.

I have an apple tree, a peach tree, and some grape vines. They’re not big trees, but they give too much fruit to eat. The squirrels get some, and we give some away. As for the rest, I began making wine and apple jack a few years back, but there’s still more fruit than I can use. Being a chemical engineer, I decided to make brandy this year, so far only with pears and apples.

The first steps were the simplest: I collected fruit in a 5 gallon, Ace bucket, and mashed it using a 2×4. I then added some sugar and water and some yeast and let it sit with a cover for a week or two. Bread yeast worked fine for this, and gives a warm flavor, IMHO. A week or so later, I put the mush into a press I had fro grapes, shown below, and extracted the fermented juice. I used a cheesecloth bag with one squeezing, no bag with the other. The bag helped, making cleanup easier.

The fruit press, used to extract liquid. A cheese cloth bag helps.

I did a second fermentation with both batches of fermented mash. This was done in a pot over a hot-plate on warm. I added more sugar and some more yeast and let it ferment for a few more days at about 78°F. To avoid bad yeasts, I washed out the pot and the ace bucket with dilute iodine before using them– I have lots of dilute iodine around from the COVID years. The product went into the aluminum “corn-cooker” shown above, 5 or 6 gallon size, that serves as the still boiler. The aluminum cover of the pot was drilled with a 1″ hole; I then screwed in a 10″ length of 3/4″ galvanized pipe, added a reducing elbow, and screwed that into a flat-plate heat exchanger, shown below. The heat exchanger serves as the condenser, while the 3/4″ pipe is like the cap on a moonshiner still. Its purpose is to keep the foam and splatter from getting in the condenser.

I put the pot on the propane burner stand shown, sealed the lid with masking tape (it worked better than duct tape), hooked up the heat exchanger to a water flow, and started cooking. If you don’t feel like making a still this way, you can buy one at Home Depot for about $150. Whatever route you go, get a good heat exchanger/ condenser. The one on the Home-depot still looks awful. You need to be able to take heat out as fast as the fire puts heat in, and you’ll need minimal pressure drop or the lid won’t seal. The Home Depot still has too little area and too much back-pressure, IMHO. Also, get a good thermometer and put it in the head-space of the pot. I used a thermocouple. Temperature is the only reasonable way to keep track of the progress and avoid toxic distillate.

A flat-plate heat exchanger, used as a condenser.

The extra weight of the heat exchanger and pipe helps hold the lid down, by the way, but it would not be enough if there was a lot of back pressure in the heat exchanger-condenser. If your lid doesn’t seal, you’ll lose your product. If you have problems, get a better heat exchanger. I made sure that the distillate flows down as it condenses. Up-flow adds back pressure and reduces condenser efficiency. I cooled the condenser with water circulated to a bucket with the cooling water flowing up, counter current to the distillate flow. I could have used tap water via a hose with proper fittings for cooling, but was afraid of major leaks all over the floor.

With the system shown, and the propane on high, it took about 20 minutes to raise the temperature to near boiling. To avoid splatter, I turned down the heater as the temperature approached 150°F. The first distillate came out at 165°F, a temperature that indicated it was not alcohol or anything you’d want to drink. I threw away the first 2-3 oz of this product. You can sniff or sip a tiny amount to convince yourself that this this is really nasty, acetone, I suspect, plus ethyl acetate, and maybe some ether and methanol. Throw it away!

After the first 2-3 ounces, I collected everything to 211°F. Product started coming in earnest at about 172°F. I ended distillation at 211°F when I’d collected nearly 3 quarts. For my first run, my electronic thermometer was off and I stopped too early — you need a good thermometer. The material I collected and was OK in taste, especially when diluted a bit. To test the strength, I set some on fire, the classic “100% proof test”, and diluted till it to about 70% beyond. This is 70% proof, by the classic method. I also tried a refractometer, comparing the results to whiskey. I was aiming for 60-80 proof (30-40%).

I tried distilling a second time to improve the flavor. The result was stronger, but much worse tasting with a loss of fruit flavor. By contrast, a much better resulted from putting some distillate (one pass) in an oak barrel we had used for wine. Just one day in the barrel helped a lot. I’ve also seen success putting charred wood cubes set into a glass bottle of distillate. Note: my barrel, as purchased, had leaks. I sealed them with wood glue before use.

I only looked up distilling law after my runs. It varies state to state. In Michigan, making spirits for consumption, either 1 gal or 60,000 gal/year, requires a “Distilling, Rectifying, Blending and/or Bottling Spirits” Permit, from the ATF Tax and Trade Bureau (“TTB”) plus a Small Distiller license from Michigan. Based on the sale of stills at Home Depot and a call to the ATF, it appears there is little interest in pursuing home distillers who do not sell, despite the activity being illegal. This appears similar to state of affairs with personal use marijuana growers in the state. Your state’s laws may be different, and your revenuers may be more enthusiastic. If you decide to distill, here’s some music, the Dukes of Hazard theme song.

A new, higher efficiency propeller

Elytron biplane, perhaps an inspiration.

Sharrow Marine introduced a new ship propeller design two years ago, at the Miami International Boat show. Unlike traditional propellers, there are no ends on the blades. Instead, each blade is a connecting ribbon with the outer edge behaving like a connecting winglet. The blade pairs provide low-speed lift-efficiency gains, as seen on a biplane, while the winglets provide high speed gains. The efficiency gain is 9-30% over a wide range of speeds, as shown below, a tremendous improvement. I suspect that this design will become standard over the next 10-20 years, as winglets have become standard on airplanes today.

The high speed efficiency advantage of the closed ends of the blades, and of the curved up winglets on modern airplanes is based on avoiding losses from air (or water) going around the end from the high pressure bottom to the low-pressure top. Between the biplane advantage and the wingtip advantage, Sharrow propellers provide improved miles per gallon at every speed except the highest, 32+ mph, plus a drastic decrease in vibration and noise, see photo.

The propeller design was developed with paid research at the University of Michigan. It was clearly innovative and granted design patent protection in most of the developed world. To the extent that the patents are respected and protected by law, Sharrow should be able to recoup the cost of their research and development. They should make a profit too. As an inventor myself, I believe they deserve to recoup their costs and make a profit. Not all inventions lead to a great product. Besides, I don’t think they charge too much. The current price is $2000-$5000 per propeller for standard sizes, a price that seems reasonable, based on the price of a boat and the advantage of more speed, more range, plus less fuel use and less vibration. This year Sharrow formed an agreement with Yamaha to manufacture the propellers under license, so supply should not be an issue.

Vastly less turbulence follows the Sharrow propeller.

China tends to copy our best products, and often steals the technology to make them, employing engineers and academics as spys. Obama/Biden have typically allowed China to benefit for the sales of copies and the theft of intellectual property, allowing the import of fakes to the US with little or no interference. Would you like a fake Rolex or Fendi, you can buy on-line from China. Would you like fake Disney, ditto. So far, I have not seen Chinese copies of the Sharrow in the US, but I expect to see them soon. Perhaps Biden’s Justice Department will do something this time, but I doubt it. By our justice department turning a blind eye to copies, they rob our innovators, and rob American workers. His protectionism is one thing I liked about Donald Trump.

The Sharrow Propeller gives improved mpg values at every speed except the very highest.

The delta variant is no big deal if you’re young or vaccinated.

The toll of COVID-19 has been terrible: 660,000 dead by my count, based on excess deaths, graph below, or 620,000 according to the CDC based on hospital records. Death rates appear to have returned to pre-pandemic levels, more or less*, but folks are still getting very sick and going to the hospital, mostly for “the delta variant.”

Weekly US death rates since October 2015.

As the following chart shows, severe symptoms of COVID are now almost entirely in the old, and unvaccinated. The risk to the young and middle aged is low, but even there, vaccination helps. According to the CDC, 72.2% of the adult US population is vaccinated with at least one shot. The vaccination, doesn’t prevent you from getting the delta variant nor from spreading it; it just protects from the most serious consequences of the disease. It seems a previous infection has the same effect, though less so.

Vaccination helps prevent hospitalization – at all ages (Israeli data)

If you’re over 60 and unvaccinated, I recommend getting vaccinated with at least one shot; the inconvenience and side-effects are few, and the benefit is large. The second shot seemswothshile too, and for all I know a third will too. Sooner or later there is a diminishing return. The benefit of masks seems is smaller, as I judge things. I notice that the disease is spreading at about the same rate in masked and unmasked states, and that the death numbers are as high, or higher in heavily masked, blue states as in red. New York and NJ are the top COVID death states, with Michigan not far behind. Masks seem to help, just not very much.

For those who want further advice, I can suggest dilute iodine gargle. I did this when I got a sore throat, I also suggest got a pneumonia vaccination, and take and adult aspirin every other day for COVID and heart-attack prevention. I also take a vitamin D tablet every few days.

If you wish to check my analysis, go here to get the raw data: https://gis.cdc.gov/grasp/fluview/mortality.html. Then, to calculate the COVID effect, I subtracted the weekly death rates in 2020 and 2021 from the corresponding week rates in 2019, correcting the deaths by 1%/year for population growth and aging. *I find that there are about 500 excess deaths per week, and I assume those are among the unvaccinated. If you are vaccinated, I’d worry about something else besides COVID-delta: heart attack, cancer, suicide, or Afghanistan.

Saving the Mini, Resurrecting my MacBook.

Our company books are done on a Mac mini 2014 that was getting slower and slower for reasons that I mis-diagnosed. I thought it was out of space on the hard drive even though the computer said there was plenty. Then my MacBook started misbehaving too, slowing to a crawl with large web-pages (Facebook) and having trouble backing up. I feared a bug of some sort. Then, 3 weeks ago, the MacBook died. It would not boot up. When I turned it on, it showed a file folder with a question mark. It was dead, but now it’s back thanks to the folks at TechBench on Woodward Ave. I lost some data, but not that much.

As it turns out, the problem was not lack of space on the hard drive, but the hard drive itself. The spinning, magnetic disc that stores my data wore out. I should have seen the problem and replaced the hard drive, but I didn’t realize you could, or should. I replaced the hard drive with a solid state memory bigger than the original, and replaced the battery too. The computer is back, faster than before, and went on to replace the hard drive on the Mini too for good measure. That was 3 weeks ago and everything is working fine.

MacBook hard drive, 120 GB. I replaced it with a solid state stick that had three times the memory and was less than half the size.

I could have bought two new computers, and I have decided to replace the 2011 desktop Mac at work, but I’m happy to have revivified these two machines. A new MacBook would have cost about $1200 while fixing this one cost should have cost $250 — $120 for the hard drive cost and $135 for the fellow who replaced it and recovered as much data as possible. Replacing the battery added another $150 with labor. I saved 2/3 the price of a new MacBook, got more hard disc, and my old programs run faster than before. Fixing up the Mini cost me $250 (no battery), and everything works fine. Because the processor is unchanged, I can still use my legacy programs (Word, pagemaker, photoshop, Quickbooks) and my music.

I’d considered trying to do the same with a 2011 Mini, but Miles at the service center said it was not worth it for a 2011 machine. I have an idea to remove the mechanism and turn this into an external, bootable drive, while transferring the data elsewhere. I’ve done this with old drives before.

In retrospect, I should have made more of an effort to backup data as soon as there was any indication that there was a problems. It was getting slower, and I needed to reboot every other day. As the disc drive wore out, data was being read less and less reliably. Data correction ate up cpu time. The fact is that I forgot I had a spinning disc-drive that could wear out. At least I learned something: hard drives wear out and need replacing. When things break, you might as well learn something. Another thing I learned is about Apple; the computers may cost more than PCs but they last. In the case of my lap book, 2014- 2021 so far.

Robert Buxbaum, March 8, 2021. This isn’t that high tech but it seems useful. As a high tech thought. It strikes me that, just as my laptop battery wore out in 7 years, an electric car battery is also likely to wear out in 7 years. Expect that to be a multi-thousand dollar replacement.
