Directory:Vibration Energy Scavenging -- VIBES
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.
- http://www.perpetuum.co.uk/ - PMG Perpetuum’s vibration energy-harvesting microgenerators are an enabling technology, making wireless, battery-free sensors a reality.
- http://www.vibes.ecs.soton.ac.uk/ - "The project is concerned with the development of Microsystems for the scavenging of electrical energy from environmental vibrations and movements."
- On July 16, 2007 from noon - 12:55 pm Pacific, Sterling D. Allan will be conducting a live interview with Steve Beeby, Ph.D., as part of the Free Energy Now radio series.

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!
