FUp-to: geek.

There are two kinds of car that seem to be surging ahead right now.

There is the fuel-cell type, and the hydrogen type (which may also be
fuelcell, but whatever.)

Fuel-cells typically use hydrocarbons (ie, gasoline (but cleaned up),
alcohol/wood alcohol, whatever burns basically) and an redox reaction
with a catalyst to directly produce an electron flow. Essentially
they're a battery, where the working chemicals need to and can be
replaced as an ongoing process. the relationship between burning stuff
in one of these and in a fire/explosion as an IC engine uses is
something like the relationship between how our cells burn sugar and
how a fire burns sugar. Much more controlled, and much cleaner.

The hydrogen cars that I've seen use a metal alloy to store hydrogen
gas (which releases hydrogen when it warms and captures it when it
cools), which is then burned for a very hot flame (exhaust being hot
water only, literally), which is placed right next to a lot of solar
cells. The solar cells sitting right next to a 2000K heat source put
out a lot more than regular solar cells, of course.

Regular electric (lead-acid-battery-powered) cars are up to being
charged in one hour or so, but I don't see them catching on until
refilling is a lot easier, faster, etc.


The problem with hydrogen cars is where do you get the hydrogen?
Generally, you'll get it by electrolysing water into hydrogen and
oxygen, or by a chemical reaction from petrochemicals.
