Massachusetts Institute of Technology engineers have developed a heat engine with no moving parts that is more efficient than a steam turbine. The researchers say the design could someday enable a fully decarbonized power grid. Their new demonstrations show that it converts heat to electricity with over 40 percent efficiency – a performance better than […]

A thin film of bismuth telluride (Bi2Te3) on top of gallium arsenide (GaAs) converts heat into electricity or electricity to cooling creating cooling devices for electronics or generating electricity from heat sources. For years, researchers have developed these thin films and while they knew it could be done, it was not clear how, because the […]

A New Way to Convert Heat to Electricity
July 12, 2012 | 2 Comments
Ohio State University researchers have figured out how to get the spin of electrons to create a current in non-magnetic materials, which is detected as a voltage in a semiconductor producing electrical power. The team is studying the new magnetic effect that converts heat to electricity and has discovered how to amplify it a thousand […]
