piezoelectric

You drink. You dance. You generate power. All the shaking-for-nothing floors of London’s nightclubs are one step behind the city’s most eco-friendly nightclub. San Francisco has got one, and so does Rotterdam. Basically, the whole idea behind this concept is to generate electricity from the shaking dance floor, electricity which would largely power the dancers’ music and lights. It’s like “pedal for electricity”, but more fun.

The general idea is that we can 'capture' energy that's used to store for later use. The sources are as diverse as electricity already in use (like a large appliance) to physical motion from our own bodily activities (like exercising or pushing a stroller.)

For example, while a vacuum cleaner is running, the back-and-forth motion and vibrations can generate small amounts of piezoelectric or hydraulic energy that powers an on-board emergency flashlight.
