Nanotechnology is quietly rewriting the rules of how small machines get their power, turning the ambient vibrations, motion and even humidity around us into usable electricity. Instead of stuffing ...
A sugar-cube-sized electric generator that feeds on environmental vibrations has been developed. It could power swarms of wireless sensors or even medical implants, researchers claim. The new ...
A hydroelectric generator produces electricity by harnessing the kinetic energy of running water. Now you can not only find stationary larger-scale hydroelectric generators but also portable micro ...
