The phrase "heat engine" might trigger some bad memories from your introductory thermodynamics course. But don't worry, I am going to show you the coolest heat engine you could possibly image—the ...

We've already heard about hoses that get wrapped around existing hot water pipes, using heat radiated from the pipe to heat water inside the hose. A new wrap-around device, however, uses that same ...

Thermoelectric generators convert heat or cold to electricity (and vice-versa). Normally solid-state devices, they can be used in such things as power plants to convert waste heat into additional ...

The No. 1 nuisance with smartphones and smartwatches is that we need to charge them every day. As warm-blooded creatures, however, we generate heat all the time, and that heat can be converted into ...

Thermoelectric generators that can convert waste heat to clean energy could soon be as efficient as other renewable energy sources, like solar, according to a team led by Penn State scientists. Using ...

Thermoelectric generators (TEGs) use heat—or more accurately, temperature differences—and the well-known Seebeck effect to generate electricity. Their applications range from energy harvesting of ...

Combustion engines, the engines in gas-powered cars, only use a quarter of the fuel’s potential energy while the rest is lost as heat through exhaust. Now, a study published in ACS Applied Materials & ...
