Technologies Inspired by Nature: Ambient Power

I read this is Wired, but can’t find a link to it but check this out:

Super-micro power generation

Micro-power generation is generating power on a smaller, house-hold level.  This is micro-micro-micro-power generation.  Above is a small power-station that is millimeters accross and can supply power to small wifi sensors.  Why is this nature-inspired?  Nature abhors a vacuum and where there is waste, you’ll find another of natures creations taking advantage of it.  In this case human activity wastes huge amounts of heat – and there tiny little power-stations soak up waste heat and turn it into power – on a micro-scale.
