U.S. Company Developing Radioactive Steam-Powered Car Engine. This radioactive car should give Greenpeace, et al, something to protest about. Just one gram of thorium would provide the equivalent of 7,500 gallons of gasoline, so a thorium-powered car could last for 300,000 miles or 5,000 hours of driving between fill-ups. At the current price of $0.25 per gram we can’t wait.
