Merle Haggard once wrote a song called Rainbow Stew. One line went, "When they find out how to burn water, and the gasoline power is gone, when an airplane flies without any fuel and the sunlight heats our home, one of these days when the air clears up and the sun comes shining through, I'll be drinking free bubbalub and eating that rainbow stew.
Well maybe the Japanese have invented a car that runs on water if this is not a hoax. I wonder how long it will take the oil barons to find a way to keep this off the market if true.
