Heat Absorbing Material Produces Clean Energy

Thallium-Doped Lead Telluride

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.” “

    The US, having less than 5% of the world’s population, uses about 25% of the world’s energy production. Fortunately, it sits on the greatest concentration of untapped and steadily increasing power: a concentration which if not lessened is expected in the foreseeable future to kill us and devastate the rest of the world: The Yellowstone Caldera. Politics aside, the practical question is how to convert heat into electricity without water. Has anyone considered whether conversion via thallium-doped lead telluride or similar material is economically viable?

    This heat absorbing material can it displace heat buy a fan?
    The fan would be blowing on a flat or circuler tube type for funelling.
