About Capturing Heat and Turning it into Electricity

ScienceDaily reports about a new discovery according to which more efficient energy can be created from heat.

The discovery is based on tiny particles called paramagnons — bits that are not quite magnets, but carry some magnetic flux. This is important, because magnets, when heated, lose their magnetic force and become what is called paramagnetic. A flux of magnetism — what scientists call “spins” — creates a type of energy called magnon-drag thermoelectricity, something that, until this discovery, could not be used to collect energy at room temperature.

The research team started testing paramagnons to see if they could, under the right circumstances, produce the necessary spin.

What they found, Joseph Heremans, professor of mechanical and aerospace engineering at The Ohio State University said, is that paramagnons do, in fact, produce the kind of spin that pushes electrons.

And that, he said, could make it possible to collect energy.
