Gas price control

[Shannen Durphey]

Hydrogen fuel cells are being used in electric cars right now.  Ford had a couple
on display in Boston recently.  The other way that hydrogen's being made is from
fuel reformers.  Pour in a tankfull of gas, out comes hydrogen to burn and liquid
waste to dispose of.  That's one approach that Honda's using.  Basically they
extend the life of a battery electric vehicle with a hydrogen powered generator.

Hydrogen engines are low compression engines AFAIK.  It's alky and propane that do
well with more compression.  Too much squeeze in a hydrogen engine and you've got
autoignition.
