No Exhaust

Technology Review says gasoline fuel cells may be coming soon (via Technabob):

If you want to take an electric car on a long drive, you need a gas-powered generator, like the one in the Chevrolet Volt, to extend its range. The problem is that when it’s running on the generator, it’s no more efficient than a conventional car. In fact, it’s even less efficient, because it has a heavy battery pack to lug around.

Now researchers at the University of Maryland have made a fuel cell that could provide a far more efficient alternative to a gasoline generator. Like all fuel cells, it generates electricity through a chemical reaction, rather than by burning fuel, and can be twice as efficient at generating electricity as a generator that uses combustion.

Burning fuel, lol.
