New Way Found to Turn Heat Directly Into Electricity
Ohio State University scientists have figured out how to capture heat and turn it into electricity. The discovery could create more efficient energy generation from heat in things like car exhaust, interplanetary space probes and industrial processes using a thermoelectric generator.
The discovery, published last week in the journal Science Advances, could create more efficient energy generation from heat in things like car exhaust, interplanetary space probes and industrial processes.
Study co-author Joseph Heremans, professor of mechanical and aerospace engineering and Ohio Eminent Scholar in Nanotechnology at The Ohio State University said, “Because of this discovery, we should be able to make more electrical energy out of heat than we do today. It’s something that, until now, nobody thought was possible.”
The discovery is based on tiny particles called paramagnons – bits that are not quite magnets, but that 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.
Heremans offered a background, “The conventional wisdom was once that, if you have a paramagnet and you heat it up, nothing happens. And we found that that is not true. What we found is a new way of designing thermoelectric semiconductors – materials that convert heat to electricity. Conventional thermoelectrics that we’ve had over the last 20 years or so are too inefficient and give us too little energy, so they are not really in widespread use. This changes that understanding.”
Magnets are a crucial part of collecting energy from heat: When one side of a magnet is heated, the other side – the cold side – gets more magnetic, producing spin, which pushes the electrons in the magnet and creates electricity.
The paradox, though, is that when magnets get heated up, they lose most of their magnetic properties, turning them into paramagnets – “almost-but-not-quite magnets,” Heremans calls them. That means that, until this discovery, nobody thought of using paramagnets to harvest heat because scientists thought paramagnets weren’t capable of collecting energy.
What the research team found, though, is that the paramagnons push the electrons only for a billionth of a millionth of a second – long enough to make paramagnets viable energy-harvesters.
The research team – an international group of scientists from Ohio State, North Carolina State University and the Chinese Academy of Sciences (all are equal authors on this journal article) – started testing paramagnons to see if they could, under the right circumstances, produce the necessary spin.
What they found, Heremans 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.
Ohio State graduate student Yuanhua Zheng is also an author on this work. The research was conducted in partnership with additional researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory and was supported by the National Science Foundation, the Air Force Office of Scientific Research and the U.S. Department of Energy.
Congratulations are in order here. This is a job well done – looking deeper and more thoroughly than those looking in the past. While not quite engineering ready, its close, and we hope a press release makes it out to let us know how the first generation of devices show their efficiency.

There are and have been, much easier and less cumbersome ways of getting electrical energy for nothing. There is an ABUNDANCE of electrical energy all around us and Tesla figured out how to harness it. (look up “Zero Point Energy”) However, at that time, Edison was a rival of Tesla and was funded by the elite banker JP Morgan who ultimately funded Edison because Tesla was interested in giving the world FREE energy. Free energy would have prevented the mass money hoarders Morgan, Rockefeller and the like from fleecing this world of its hard earned money. Free energy for the world would have completely changed the world for the (much) better.
