We really don't suffer from a shortage of energy. We suffer from an inability to capture it. Which is why little inventions like this are so very cool. Steve Beeby of the University of South Hampton was in charge of developing the device, which is pretty much just a couple of magnets allowed to wobble near a coil of copper wires. But all together, it harvests power from vibrations.
In optimal situations, the device can capture about 30% of vibration energy and turn it into electricity. That electricity can in turn power a wide range of small devices. The article at New Scientist lists accelerometers for monitoring bridge stress as a near-term use, and continually charging pace-makers for the long term, but I've got some ideas of my own.
First, never charge your remote control again. The vibrations of lifting, tossing, and jostling it around amongst couch cushions is power enough! Wrist watches, of course, would be a perfect application as well as cell phones, as component voltages get lower and lower.
Anywhere there's movement and a little bit of power is needed, look no further than the micro-generators of the future.
