Re: Slightly off topic H2 (very little Alfa content)



You have let the enviro-whako's dirty little secret out of the bag, here. Almost none of the alternative-to-gasoline fuels are in any way practical. As you say, hydrogen requires more energy to make than it stores. Enough alcohol to replace gasoline would require that every acre of arable land on the planet be given over to the growth of corn, sugar beets or sugar cane from which to make the fuel-grade alcohol. Batteries, of course, just shift the point of pollution to a central location- the power plant, and that infrastructure would have to be enlarged a thousandfold if everyone were to buy an electric car. Since we Americans let our enviro-alarmists kill-off nuclear power in this country, the idea of thousands more coal and oil fired power plants built solely to recharge people's automobiles overnight, is just too terrible to contemplate. Fuel cells have the same problems as burning hydrogen, because its essentially reverse electrolysis. And again, fuel cells produce far less energy than it takes to make the hydrogen that they require (the oxygen required, ostensibly, could come from the air). The best alternative technology at the moment is the hybrid-electric/diesel car. These work like the current Toyota Prius or the little Honda two-seater (the one with the fender skirts in the rear), except they would use diesel engines instead of gasoline. So it looks like we will be able to run our gasoline-powered Alfas for many years to come, because there ain't no practical alternative to gasoline anywhere on the horizon.

Uh, before you get excited about hydrogen power, ask where it will come
from in volumes sufficient to power the world.

Water? Takes more energy to split it than you get out of it, and where is
the energy to split it?
Various forms of alternate electricity (hydro, thermal, air....)- not
enough supply to generate the H2 requirements of the world.

Right now, the best source is natural gas, but that generates CO2, which
puts us right back were we started.

Does anyone know if you can patent ideas?....

One better idea is a gasoline powered fuel cell- as soon as you get to 25%
average efficiency, you are better than an IC engine (on an average
drive). Theoretically possible, heck yes!

Personally, I still don't see a realistic threat to the gasoline powered IC
engine. Gas has the highest specific energy, its easy to make, we have
control of its serious pollution problems. Most importantly, for an equal
of a 100hp 4 cyl cheap motor, it costs somewhere between 20-50 TIMES as
much. Wanna spend $50k on an Escort.
