Researchers at the University of Southampton, UK, have developed a sugar-cube-sized (7 x 7 x 8.5 mm) electric generator that feeds on environmental vibrations. They say it is the most efficient micro-generator yet developed -- ten times more powerful than any other similar device -- converting 30% of environmental kinetic energy into electrical power.
The micro-generator harvests power electromagnetically by exploiting the wobbling of several magnets attached to a millimetre-sized cantilever.
The technology has a potential to eventually power small, low-power devices without batteries, such as wireless sensors or medical implants.

Nice but Insignificant

Compared to global energy needs, this is insignificant
though a nice device. Even if it becomes the cell
phone charger of the future, it won't get us off the
oil habit. Let's leave the Congress:Top 100 Technologies -- RD for the big
stuff.
