Obscure technologies, part 4

I just found this Wired story about a futuristic train, made out of aluminum and driven by a airplane style propeller at the rear. The Schienenzeppelin was actually a railcar rather than a train (i.e. it was a single unit, not a set of cars propelled by a locomotive), and made it’s first test run in 1930. In 1931 it set a railway speed record of 230.2 km/hr. That record was not beaten until 1954 and, according to Wikipedia, still has not been beaten by any gasoline-powered rail vehicle.

There were a number of issues with the Schienenzepplin that stopped it from ever going into production, one of the most important of which was the safety of an open propeller at passenger stations. The one prototype was scrapped just before World War II.

Incidently, the Schienenzeppelin was not the first attempt to use aircraft propulsion on a rail vehicle: the Soviet Aerowagon was built as early as 1921, but it crashed on it’s second trip, killing all aboard.

Did you ever wonder…

when a railroad locomotive goes off the track, how do you get it back on? The thing weighs about 170 tons, but if you thought that it required a big crane, you were wrong.

I think I picked the wrong specialty

I should have chosen this one. Now that’s what I call experimental archeology!

Mammoth carving

According to this press release, a carving of a mammoth was incised on a bone fragment discovered at an archaeological site in Florida. This is an exciting discovery, and the first such image found on a bone in the Americas. However it is a little extreme to claim, as the press release does, that this is the only known image of a proboscidean (aka animals with trunks – elephant relatives) found in the Americans. There are at least three petroglyphs in Utah that appear to depict mammoths or mastodons, one of which I blogged about a while back.

Still, Pleistocene-era art in the Americas is extremely rare, and this is a remarkable find.

Chemistry FAIL

I though everyone who paid attention in high school science knew how electrolysis works. It’s not that complicated. And it’s one of the more common chemical processes used in industry. So I guess that the engineers who designed the U.S. Navy’s newest combat ship were not among those paying attention. Neither, it appears, were the people who approved the design on behalf of the Navy. That’s the only conclusion I can draw from the discovery that the ship, the USS Independence (LCS-2), is dissolving away.

Honestly, how do you get a job designing ships without understanding the effects of immersing different kinds of metal in salt water?

City life can drive you crazy

It looks like neuroscientists have discovered what social scientists and epidemiologists have know for a long time. It’s been well established that urban populations suffer from certain mental illnesses, including schizophrenia, at a higher rate than rural populations. Now a German team has used MRI scanning to investigate differences in brain activity between urban and rural dwellers. In short, college students from the city showed a significantly greater response to social stress than kids from the country.

The finding were published in Nature, and also reported on the journal’s web site.

Technology

I sure it won’t be a shock to regular readers of this blog that I am fascinated by the development of technology. One of the ways humanity is different from every other species on Earth is that tools and their use profoundly shape nearly every aspect of our lives. And not just in recent times: the very first anatomically modern humans already possessed a sophisticated tool kit that helped them acquire and process food, manufacture clothing and adornment, build shelters, and perform all the various tasks of daily life. We are the species that interacts with our environment through technology.

That’s one of the reasons that I find the archaeology of the American West so fascinating. It was a time of very rapid change, in technology as well as in many other aspects of culture. The technology of mining and milling advanced rapidly in the second half of the nineteenth century, with many of the new techniques being invented in Nevada and California. During that same period, developments in transportation and mechanization transformed a society largely made up of independent farmers into one of widespread wage labor.

At the same time, indigenous cultures were also undergoing profound technological changes. American Indians adopted many Euro-American technologies, but did not necessarily employ them in the same ways that white Americans did. At times, old and new technologies were blended as, for example, in the use of glass telegraph insulators as a material for making projectile points.

Both Indians and white Americans at times adopted new technologies without fully understanding their ramifications – both positive and negative. Both Indians and white Americans sometimes made technological choices that were, in hindsight, unwise. And during the nineteenth and early twentieth centuries, new technologies helped produce profound changes in both Indian and white American cultures.

Anthropology quote of the day

Guilt may be good for contemporary American souls; but guilt, as much as pride, is a way of asserting one’s own version of history. The current liberal preoccupation with the conquest of America as a scenario of the triumph of white greed over red innocence too often serves merely to cast the Indian as a straw man of defeated virtue. One does not have to learn about the Indian himself; it is enough to find out that our grandfathers killed him and then go off to feel sorry for it. – Stefan Jovanovich (From the introduction to Adolf Bandelier’s The Delight Makers.)

Last roll out

Over at the NASA web site there is a wonderful picture of a very sad event – Atlantis being moved to the pad for the last launch ever of a space shuttle. I call this event sad rather than bittersweet only because there is no replacement vehicle. I can’t deny that the shuttle needs to be retired; it has served honorably, for far longer than anybody had a right to expect. It really should have been taken out of service twenty years ago. But twenty years ago, NASA didn’t have anything to use in its place. Sadly, they still don’t.

Let them eat poop

Straight out of your favorite overpopulated science fiction dystopia, a process developed by a Japanese researcher allows human feces to be reprocessed into meat. This is nothing new, of course. Natural decay processes use human and animal waste to feed the next generation of plants and animals. Nearly everything we eat is made, at least in part, of reprocessed feces.

And yet, even though I know this, I don’t think I’d want to eat one of Dr. Ikeda’s poo burgers.
