One small step

I don't have much to say about it, but there's an interesting article in the Guardian about the possible harvesting of tiny energy sources, such as footsteps or vibration induced by passing trains.

It's difficult to guess whether this is the same variety of media-driven sci-fi as predicted personal hover cars by 2001, but it sounds as if it has great potential. I doubt piezoelectric conversion would be enough for domestic heating or lighting, but it could be adequate for energy-efficient personal electronic devices and collective possibilities are impressive.


You know what's always confused me? Why no-one's had the idea to put a piezoelectric charger and gyroscope thingies into wireless mice and keyboards. It wouldn't power them completely, but it would extend the life of the battery, surely?
