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 100 berths for the big stuff.

Low Power, Deep in R&D

Still very early, and extremely low power, but it WORKS!
