U. of Minnesota researchers demonstrate new method for direct conversion of heat to electricity

Green Car Congress

Researchers at the University of Minnesota have demonstrated a new method for the direct conversion of heat to electricity using a multiferroic alloy, Ni 45 Co 5 Mn 40 Sn 10 , which they had discovered earlier (Srivastava 2010). 2011), The Direct Conversion of Heat to Electricity Using Multiferroic Alloys. note in their paper.

New Solar Energy Conversion Process Could Boost Efficiency

Green Car Congress

Stanford engineers have developed a process—photon-enhanced thermionic emission, PETE—that simultaneously uses the light and heat of the sun to generate electricity in a way that could make solar power production more than twice as efficient as existing methods.
