Collecting leaking energy

Definitely cooler than Tesla coils and wireless DC. New power source: wall vibrations

Imagine using a computer that runs on energy generated from your building's wall and window vibrations. Masayuki Miyazaki, a senior researcher at Hitachi Co. Ltd.'s central lab in Tokyo, is trying to do just that.

He recently made a tiny generator that converts building movements into electricity, creating enough energy to run a temperature or light sensor once an hour. Though the output is small right now, only about 10 microwatts, scientists predict the generator's potential could be huge in coming decades - possibly used in battery-free computing systems.
