I keep thinking of doing this with an old vehicle, except keep
the parts down, like the old days, but use natural gas instead of
gasoline. Natural gas doesn't mind the high compression! I work in
natural gas, and with ga$oline co$t$ going up, it's looking more

Likewise, it is not that difficult to run a car engine on hydrogen. I
see all these news stories that the hydrogen economy must wait till we
get fuel cell automobiles. Not true. It is far easier to convert an
existing engine to run on hydrogen than it is to develop the practical,
low cost fuel cell.

One does have to use EGR with hydrogen to cut down on NOx emissions, but
we know how to make EGR systems!

But unless we can use the hydrogen radically more efficiently than we
do gasoline, there's no advantage to hydrogen, as it will take as much
or more energy to produce said hydrogen than we are currently directly
using in the form of gasoline or Diesel motor fuel. There are
theoretical limits to the efficiency of an IC engine that aren't
present in a fuel cell/electric motor combination. That is why
everyone is waiting for a practical fuel cell before making the switch.
(well, everyone but GWB, that is. I guess nobody's clued him in that
using H2 in an IC engine won't do a damn thing to solve our dependency
on oil.)
