Researchers One Step Closer To New Kind Of Thermoelectric 'Heat Engine'

Researchers who are studying a new magnetic effect that converts heat to electricity have discovered how to amplify it a thousand times over - a first step in making the technology more practical. In the so-called spin Seebeck effect, the spin of electrons creates a current in magnetic materials, which is detected as a voltage in an adjacent metal. Ohio State University researchers have figured out how to create a similar effect in a non-magnetic semiconductor while producing more electrical power. They've named the amplified effect the "giant spin-Seebeck" effect.
