A rotating inside the case is attached to a relatively large gear which meshes with a very small . As the wearer moves, the pendulum turns and spins the pinion at a very high speed - up to 100,000 . This is coupled to a miniature which charges a storage device which is a (s) or a rechargeable . A typical full charge will last between two weeks and six months.

A technology capable of harvesting lightning energy would need to be able to rapidly capture the high power involved in a lightning bolt. Additionally, lightning is sporadic, and therefore energy would have to be collected and stored; it is difficult to convert high-voltage electrical power to the lower-voltage power that can be stored. In the summer of 2007, an company called Alternate Energy Holdings, Inc. (AEHI) te.
