Compaq has patented a device that uses typing to charge up notebook batteries. The power generator was invented by Compaq designer Adrian Crisan and consists of a small magnet and coil on each key. When keys are pressed, the mechanical energy of that movement is turned into electrical energy and fed back into the notebook's battery. Compaq said the device could be used either to lengthen the lifespan of the notebook or to reduce the size and weight of the primary battery.
