Gentlemen, Boot Your Engines

How would you power electronic devices if you’re ‘off the grid’, like a soldier or aid worker? Batteries are cumbersome and wasteful, and solar panels aren’t very portable yet. Researchers at MIT believe the answer may be a tiny gas turbine engine, made from etched silicon wafers in the same manner as microchips. This is still conceptual vapourware at the moment, but MIT are nororious for building incredible projects, and the promised utility of this little device should ensure investment interest.
