The Heat Engine With No Moving Parts, Explained

What if the heat we throw away could power the country? Dr. Lonnie Johnson, the engineer who invented the Super Soaker, joins Matt to explain the JTEC, a heat engine with no moving parts. It uses hydrogen and an electrochemical membrane to turn low-grade heat straight into electricity, no pistons or turbines. Johnson says roughly 20% of America's abandoned oil wells could cover all US power needs, and he pegs untapped waste heat at $190 billion a year in electricity. So is direct heat-to-power finally within reach? Or is the lab still a long way from your grid?
