I was reading on the Reuters.com website that researchers are working on a new material that converts heat into electricity. The hope is that using this material will help cars get more miles to the gallon. According to the article, only about 25% of the energy produced by a typical gasoline powered engine is used to move the vehicle, and the rest escapes through the exhaust pipe. The researchers are hoping that this new material will enable the car to recycle some of that escaped heat into energy that will power the car. That would be awesome!
