I don't want to hear another word from a Marxist masquerading as a scientist. I'm fresh out of patience for two-trust-fund Savanarolas trying to impress some lumpen girl with a cryptkeeper complexion and a shock of underarm hair by joining ELF and burning down condos and keying elaborate station wagons. I don't want another exposition on why the world will end yesterday by a hayseed Frankenstein's monster droning through an apocalyptic PowerPoint presentation with the graphs upside down and backwards.
And I especially don't want to hear another word about hydrogen. Why? Because it's stupid, that's why.
The Queen in Lewis Carroll’s Through the Looking Glass says that she could believe “six impossible things before breakfast.” Such an attitude is necessary to discuss the hydrogen economy, since no part of it is possible. Putting aside the intractable issues of fundamental physics, hydrogen production costs, and distribution show stoppers, let us proceed to discuss the problems associated with the hydrogen cars themselves. In order for hydrogen to be used as fuel in a car, it has to be stored in the car. As at the station, this could be done either in the form of cryogenic liquid hydrogen or as highly compressed gas. In either case, we come up against serious problems caused by the low density of hydrogen. For example, if liquid hydrogen is the form employed, then storing 20 kilograms onboard (equivalent in energy content to 20 gallons of gasoline) would require an insulated cryogenic fuel tank with a volume of some 280 liters (70 gallons). This cryogenic hydrogen would always be boiling away, which would create concerns for those who have to leave their cars parked for any length of time, and which would also turn the atmospheres in underground or otherwise enclosed parking garages into explosive fuel-air mixtures. Public parking garages containing such cars could be expected to explode regularly, since hydrogen is flammable over concentrations in air ranging from 4 to 75 percent, and the minimum energy required for its ignition is about one-twentieth that required for gasoline or natural gas.
Robert Zubrin at the New Atlantis calmly eviscerates hydrogen weinies, and stomps on their bits. There will be some mathematics, and unlike the 'Reality Based' community, his numbers add up.
You want a hydrogen economy? Go to the sun, and get me some.
