Using research from the Ohio labs of the old Standard Oil of Ohio (Sohio), now a division of BP, Lee has a solid oxide cell that can be configured to run on natural gas, soy oil or farm wastes.
Another is to use powerful solar cells to collect sunlight in conjunction with an efficient solid oxide fuel cell.
ENGADGET: Marines eye solar energy to eliminate dependency on fuel generators (video)
That's when the MIT duo decided to miniaturize a solid-oxide fuel cell instead.
Lilliputian's engineering miracle was in designing a tiny solid-oxide fuel cell that instead of melting everything in its vicinity is merely warm to the touch.
On the contrary, start-up companies like Westwood, MA-based Acumentrics are similarly pursuing a solid-oxide fuel cell technology tailored to the needs of the military.
FORBES: Lockheed Gambles On Green Generators For U.S. Military
The Tennessee Valley Authority (nyse: TVC - news - people ), a big Chattanooga employer, is taking the output from the 5-kilowatt solid oxide fuel cell that the center is experimenting with.
Bethesda, Maryland, is developing solid oxide fuel cell generators that will replace reliance on traditional battlefield power solutions and potentially reduce the fuel required for tactical generation of electric power by half or more.

Frankly, I believe that solid oxide fuel cells are the better technology in the long run, but Fuel Cell Energy owns 43% of the shares of VERSA Power that also makes solid oxide fuel cells.
Dr Kamat and his team covered the surface of an experimental cell made of cadmium sulphide, zinc oxide and titanium dioxide with nanotubes, so that the tubes stuck up from the surface like hairs.
There are two dominant flavors of fuel cell: proton-exchange membrane (PEM) and solid oxide.
