Jun 30, 2026 - How the Super Soaker Inventor Just Killed the Steam Engine
How a Toy Inventor Built the Most Efficient Heat Engine Ever. What if all the heat your car engine, a factory, or a power plant throws away could run the grid instead? A new engine turns that waste heat into electricity, even the low-grade stuff today`s best systems struggle with. It has no moving parts, and the wild part is who built it. Dr. Lonnie Johnson, the Super Soaker inventor, dreamed up this heat engine, called the JTEC. It could one day capture clean energy from industrial exhaust, and even geothermal heat. So is the JTEC really the machine that turns waste heat into power? Or will it make a smaller splash than the Super Soaker?
