Team Doubles Efficiency of Thermoelectric Material: Good News for Car…

Scientists at Ohio State University have taken a thermoelectric material that's been used for decades to power deep-space probes, and worked out how to double its efficiency. That's good news: thermoelectrics convert heat directly into electrical energy. By catching exhaust heat, the new material may allow car… » 7/25/08 5:24am 7/25/08 5:24am
