For many locations around the world where U.S. troops are deployed, one of the only ways to get electricity is through gas generators. Not only are they noisy, but they also require constant resupplies through fuel convoys, which are often a target for enemy attack. But scientists working on the problem for the Office of Naval Research say they’ve just successfully tested an alternative to generators. The whisper-quiet new fuel cell unit produces the same amount of power as a gas generator on half the fuel, and they’re looking at ways to make it even more efficient. Don Hoffman, program officer for power generation and energy storage systems at ONR, told Federal News Radio’s Jared Serbu how the technology works.
