They built 500 Mile per Gallon engines then vanished — what Big Oil and the energy elite don’t want you to know.   They built real engines that claimed 200–500 miles per gallon—then vanished under layers of secrecy. This investigation exposes the hidden history of suppressed energy inventions, from Tom Ogle’s vapor car to Stanley Meyer’s water fuel cell, magnetic motors, and battery breakthroughs buried by governments and corporations.   🔍 In this episode: • The Invention Secrecy Act of 1951—how 5,000+ energy patents remain classified. • Inventors who disappeared after creating working prototypes. • How fuel efficiency threatens the global oil economy. • Why EVs didn’t free us—they repackaged the system. • What “free energy” really means—and why it’s still dangerous to those in power.   If one working 500 MPG engine ever hit the market, the oil economy would collapse. This isn’t conspiracy—it’s a cover-up story.
