Soon your car will be able to run off the noise around it.
Self-powered devices possible, says researcher | Science Blog
But wait! If the cars are quiet then we need to have noise makers to power our cars but then our cars don't need to be quiet so...(cue smoke from brain):tongue:
Self-powered devices possible, says researcher | Science Blog
Imagine a self-powering cell phone that never needs to be charged because it converts sound waves produced by the user into the energy it needs to keep running. ...
Utilizing materials known in scientific circles as "piezoelectrics," Cagin, whose research focuses on nanotechnology, has made a significant discovery in the area of power harvesting – a field that aims to develop self-powered devices that do not require replaceable power supplies, such as batteries.
