Not that hydrogen or even solar powered vehicles are bad alternatives, but they have (and had) cars that run on water; even a French company developed a car recently that runs on fuel (petrol) that can get 7,000 MPG.

Considering that the vehicle was:

-running on fuel cells
-made of a aluminum frame and fiberglass body
-fully aerodynamic
-probably never topped 20mph
-and they extrapolated the data

id have to agree with Ferris.

The vehicle is the absolute most extreme of efficiency, not practicality.

That was from the Shell Eco-Marathon and it more than likely used a weed-whacker or model airplane motor. They have been doing these marathons for years now and have very little real-world value. Like someone else mentioned, they use fiberglass and carbon-fiber bodies, super light aluminum frames, and the tiniest engines. They can barely propel one human more than 15 mph. These are not cars, they are 21st century soapbox racers.

Oh, and the 7,000 MPG is not its true fuel efficiency. They extrapolate this figure from running on one liter of fuel around a race track. There is no way in hell you would get 7,000 MPG from these things in real world conditions. There are always a few folks who see 7,000 MPG in an article and get all "OMG WTF IT'S AMAZING!"
