"
This system could produce hydrogen anyplace that there is wastewater near sea water," said Bruce E. Logan, Kappe Professor of Environmental Engineering. "It uses no grid electricity and is completely carbon neutral. It is an inexhaustible source of energy."

Suspended Animation with Rotton Egg Gas!?!? - It may smell like rotten eggs, but it turns out H2S may be able to slow down the chain of chemical degradation that causes death in cells that are deprived of oxygen. Biologist Mark Roth can supposedly take a lab rat, stop its heart with a dose of hydrogen sulfide, and bring it back to life an hour later just by turning off the gas. Interesting...

Inspired by a recent
Wall Street Journal* article, Robert Rapier, chemical engineer, peakist, blogger, and currently chief technology officer for a bioenergy company, reviews the
pretenders,
contenders, and
niche players in the emerging field of green energy, with particular consideration of liquid fuels. Meanwhile, the boffins at Foreign Policy consider the
risks of the coming of the green energy era, and
depict the end of the oil age. (Both part of FP's extensive look at the
end of oil;
previously.)

Solar cell directly splits water for hydrogen. Thomas E. Mallouk and W. Justin Youngblood, postdoctoral fellow in chemistry, together with collaborators at Arizona State University, developed a catalyst system that, combined with a dye, can mimic the electron transfer and water oxidation processes that occur in plants during photosynthesis. They reported the results of their experiments at the annual meeting of the American Association for the Advancement of Science today in Boston.

Mike Strizki lives in the nation's first solar-hydrogen house. "The technology this civil engineer has been able to string together – solar panels, a hydrogen fuel cell, storage tanks, and a piece of equipment called an electrolyzer – provides electricity to his home year-round, even on the cloudiest of winter days.
Mr. Strizki's monthly utility bill is zero – he's off the power grid – and his system creates no carbon-dioxide emissions. Neither does the fuel-cell car parked in his garage, which runs off the hydrogen his system creates."

Is this BMW version what some were waiting for? I've heard about complaints on hybrid performance. BMW claims to be the best in performance. But did they miss the boat?

Stan Meyer invented a
water powered car that estimates showed could travel from one US coast to the other on 22 gallons of water. He shows the in car in operation in this
old news clip. So what ever happened to him? He died after eating at a restaurant on March 21, 1998. An autopsy report showed the cause of death to be
poisoning.

"A Hydrogen Atom is only about a ten millionth of a millimeter in diameter, but the proton in the middle is a hundred thousand times smaller, and the electron whizzing around the outside is a thousand times smaller than THAT. The rest of the atom is empty. I tried to picture it, and I couldn't. So I put together this page - and I still can't picture it." Awesome illustration on perspective and particles - *warning* very wide page, may be dangerous to your browser. Also, the
relative size of planets (via the always interesting
37signals blog.)

Hydrogen fuel has been
discussed many times on MeFi, but I wasn't able to find a previous link to this
video clip (Google Video warning) showing Jack Nicholson, circa
1978, showing off his hydrogen powered car. The accents of the broadcasters, in case you're wondering, are east coast Canadian, possibly
Newfoundland.

Water Power (embedded video). Inventor creates a hydrogen-powered vehicle that can run completely on water, or rather HHO. This is perhaps nothing new (or is it?), but fasinating nonetheless. Warning: annoying local news reportage.

Hydrogen Cars. I had been expecting something akin to
the Sinclair C5, but these are full production models within the Ford Focus range. The article predicts that although they'll initially appear in niche markets such as public transport, in a few years we'll all be able to drive about in them, creating a cleaner, happier world.

Michigan: Land of Alternative energy? "DTE Energy [Detroit Edison]
said Monday it has a deal to build and test a hydrogen system capable of generating more than 15,000 kilowatt-hours of electricity. The $3-million test project, funded by DTE and the U.S. Department of Energy, is to be operational in 2005. " Wayne State University is also
jumping on the bandwagon. What, if anything, is your town doing (or claiming it
will do)?

"Suckers. They're all watching the wrong cards. They're watching the borax. They're watching the fuel cell and its clean tailpipe. They should be watching the hydrogen. That's the payoff card."
Car and Driver takes issue with the
Hydrogen on Demand system used in Chrysler's
Natrium concept and billed by the
media as a possible solution to the
problem of producing, storing, and transporting hydrogen.

"If we sort out Iraq and Detroit develops a hydrogen engine,"
says a U.S. diplomat, "Saudi Arabia will go back to being a fascinating, benighted part of the world that people don't visit."

Huge hydrogen stores found below Earth's crust. "Scientists have discovered vast quantities of hydrogen gas, widely regarded as the most promising alternative to today's dwindling stocks of fossil fuels, lying beneath the Earth's crust. The discovery has stunned energy experts, who believe that it could provide virtually limitless supplies of clean fuel for cars, homes and industry." This discovery sounds too good to be true (for us energy-hungry humans that is, bad news for the bacteria.)

These guys cool and trap anti-electrons (positrons) and at the same time cool and trap anti-protons. Why? Because they want to make cold
anti-hydrogen and compare its properties with ordinary hydrogen. Pretty cool all round, really.
"Any difference between antimatter and matter would be extremely interesting since we do not yet understand why we have a universe made of matter. We would expect that the big bang that originated our universe would create equal amounts of antimatter and matter, which would then annihilate, leaving nothing. The great mystery is why enough matter was left over that we and our matter universe could exist."

HydroGen1, a fuel-cell vehicle of tomorrow The prototype's power comes from electric motor supplied with current from a fuel cell that runs on pure hydrogen. The hydrogen supply is stored in liquid form at minus 253 degrees Celsius in a special storage tank called a "Cryo tank," which is similar to a vacuum storage bottle.
I'm just imagining the fun they will have at the Insurance Institute of Highway Safety while crash testing this thing.
