Editor of maybe car and driver on his last editorial went rogue many years ago. Talked about this, the fisch carb (200mpg caddilac) and many others. Explained these were all bought and hidden to protect the energy industry. There was one in Cali too, half water half fuel. Tested with news in Porsche 944. All over news one night, gone the next, phone disconnected and business gone in a week. Was an Irish company, invented a magnetic motor. Worked, they went public in a big way. Company went to demonstrate, had ‘problems’ and their webpage went stagnant, never heard from them again. Many many examples.
