Students build Hydrogen Powered 1,336 MPG vehicle...

As was mentioned already, the problem is that producing the hydrogen takes more energy than the resultant hydrogen contains. Remarkably, one of the most efficient alternative "fuel" cars today is a working French design, already in small-scale production that runs on compressed air.

I've read about that..but its the same mojo. You have to use power to compress the air, unless you use windmills or hydro power.
