307: From Super Soakers to Heat Engines with Dr. Lonnie Johnson

44 min24 juni 2026

The inventor of the Super Soaker, Dr. Lonnie Johnson, joins Matt to talk about his most ambitious project yet: the JTEC, a heat engine with no moving parts that converts low-grade waste heat straight into electricity. They get into how it actually works, why Johnson thinks it could run far more efficiently than what we use today, and the long road from a 2003 idea to the first commercial unit. Plus how a billion-dollar water gun quietly funded a quarter-century of clean-energy research.
