Jet-powered cellphones?
p2pnet.net News:- Chip-based micro-jets could provide enough energy to power a cellphone.
“The key advantage of microengines is that they pack in at least 10 times more energy per volume of fuel than conventional lithium batteries, take up less space and work more smoothly than much-touted fuel cells,” says a New Scientist story reporting on work undertaken by David Arnold and Mark Allen of the Georgia Institute of Technology
By spinning a tiny magnet above a mesh of interleaved coils etched into a wafer, Arnold and Allen, “have built the first silicon-compatible device capable of converting mechanical energy – produced by a rotating microturbine – into usable amounts of electrical energy,” says the story, going on:
