Luc G. Fréchette of the Columbia University Microsystem Engineering Laboratory has developed a 20W electrical generator powered by a hydrogen turbine just 4mm in diameter. For more details, read the Wired article or an older Popular Science article. The tiny generator is more efficient than any battery and is expected to find military and commercial uses including robotics.
