Aiming to create a miniature motor capable of 1 million revolutions per minute, electronics researchers at
ETH Life in Zurich are half-way to their goal.
The gas turbine-powered device produces force equivalent to 100 watts and is 95 percent fuel efficient, and gets 10 hours of operation out of the tank.
Though there's a raft of problems in increasing the power-output of such miniaturized motors, designed as they are to operate close to their components' frictional and inertial tolerances, Gizmag reports on the many uses these pint-sized powerhouses could offer. An yet, somehow, they forgot the obvious one.
