Heat Absorbing Material Produces Clean Energy

Scientists have invented a material that converts absorbed heat into energy without pollution. The average car engine wastes up to 60% of the power it produces in the form of waste heat and uses only 25% of it’s energy to actually power the car.
Dr. Joseph Heremans of Ohio State University has recently developed a thermoelectric material that outperforms the previous leader by 2:1. Entitled thallium-doped lead telluride, the material promises to make cars and other engines more efficient by capturing waste heat without the use of moving parts. Moreover, it operates best between 450 and 950 degrees Fahrenheit, which is a typical temperature range for such engines.
According to Heremans, “The material does all the work. It produces electrical power just like conventional heat engines – steam engines, gas or diesel engines – that are coupled to electrical generators, but it uses electrons as the working fluids instead of water or gases, and makes electricity directly.” “
