Piezoelectrics Promise To Create Energy from Everything

What if your house could generate electricity from the noise of the cars on the road? Or if the waste heat generated by your air conditioner could help put a dent in that expensive summer electric bill? As the demand for cheaper and more renewable energy sources increases, piezoelectrics - a class of material that produces an electric potential when mechanically deformed - may hold the key to unlocking the energy flowing all around us. There are applications of this technology already in place - certain dance clubs in Europe utilize dance floors with piezoelectrics to help power the lights. What would really be useful to the consumer, however, would be small piezoelectric systems that could assist in powering personal electronic devices. Read More.
