Georgia Tech Unveils Prototype Nanogenerator

Researchers at Georgia Institute of Technology have created a working prototype nanogenerator capable of generating as much as 4 watts per cubic centimeter of continuous direct current. The generators are green (to use), drawing power from natural motion in the surrounding environment. They are based on non-toxic chemicals and should be safe for use in biomechanical implants, but that's not their only potential use. From the article: "If you had a device like this in your shoes when you walked, you would be able to generate your own small current to power small electronics," Wang noted. "Anything that makes the nanowires move within the generator can be used for generating power. Very little force is required to move them."

Conservation of Energy

I wonder if i could generate enough energy from my hands shaking to power my espresso machine. that would be useful :)

Kinetic

Quite a few years ago I had a watch powered by the exact same principle. Merely walking around would generate the power it needed to keep itself running. Unfortunately as I got more and more into computers I found the watch holding less and less of a charge, until eventually it stopped working altogether. If I had to choose between movement and a watch or computers I would have to say I'm glad there's a clock in the bottom right corner of the screen.

Wind power generator

Somebody should attempt to coat the blades of a windmill with these.
