The idea has been floating around for several years now, but MicroGen Systems finally put the concept into creation with its new line of batteries. Instead of solar rays or lithium-ion, these revolutionary power cells are powered by vibrations.
It seems the hippies had it right the whole time -- all we needed were good vibrations! Harnessing the latent power of shaking and oscillating mechanics, these batteries are more or less carbon neutral. Less than 1 square centimeter, MicroGen System's tiny batteries work by switching on a circuit board whenever the device is disturbed or moved, allowing it to store the kinetic energy. The power cell can only produce about 200 microwatts -- powerful, considering its minuscule size.
Most batteries have to be assembled by hand, whereas MicroGen's can be widely produced on the cheap due to their compatibility with existing chipset technology. Groovy!
