Back in 1978, Jack Nicholson was ahead of his time.

Last week, Genepax Co demonstrated a car that it says runs on water. Video of the demonstration is here.

If hydrogen-cell cars are no good, how about hydrogen-cell motorbikes!

Is solar-powered flight getting any nearer? As noted previously on Metafilter, solar powered aviation has travelled a long way since the heady days of the Gossamer Penguin. But could it actually one day power commerical flight?

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.

All these worlds are yours, save Europa. Attempt no landings he...llo! What the hell is wrong with you!? Did you just nuke Jupiter?

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.

With gas prices rising, SUV sales (16-20 mpg city) have been declining. What are some alternatives for urban commuters? Prius (56 mpg) and other hybrid vehicles. SmartCar (50 mpg city; available in Canada, but not the US) and other microcars. Electric motor scooters and bicycles. Electric cars like the General Motors EV1 seem to be stalled, although people are working on a battery-powered SmartCar. What about hydrogen vehicles? In the medium term, MIT's Laboratory for Energy and the Environment doesn't think they'll outperform hybrids (full report). A comparison of fuel-cell and battery electric vehicles gets into some of the details of how they work.

Smaller than a DVD player - small enough to sit comfortably under the hood of any truck or car - it could be big enough to solve the world's greenhouse gas emission problems, at least for the near future. In fact, it could make the Kyoto protocol obsolete.

Around the world on 8 litres of fuel? I'd be more excited about this if the automotive industry hadn't been teasing us with cool, feature laden concept cars for years, and then actually producing boring combustion engine sedans.

Larry's U.S. Navy Airship Picture Book. No longer available in paper, but still with us in bits. Lawrence F. Rodrigues served in the Navy, in Airship Squadron 3, out of Lakehurst NAS, beginning in 1953. This website presents photos and memories of his service days. It's fascinating.

As a bonus, you may wish to read up on the Details of Modern Airship Construction, ca. 1927, or to return to Dannysoar's site to observe the plans for a twelve-foot model helium-lofted rubber-band powered flying stick-and-tissue dirigible (scroll down a bit).

Up Ship!

didn't someone end a post with those words this year? Google didn't raise hide nor hair of it for me...

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.

We're now one step closer to making fuel cell cars. It was announced a few days ago that Quantum Technologies' Hydrogen Storage Tank capable of powering current fuel cell cars up to 300 miles has received the highest rating from a German auto safety commission. This is part of the previously discussed billion dollar effort by GM to bring fuel cell cars to the market. Seems like we're getting one step closer to finally saying goodbye to fossil fuel powered cars.

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.)

Iceland moves to become the first country to replace fossil fuels with hydrogen for all its energy needs. I find it fitting that a society descended from Vikings will become the world's first hydrogen society.

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.
