As mentioned, NextGenCar.com is always on the lookout for game-changing Next Generation Car engine technology. Could a Thorium-powered car be just that? Thorium is a radioactive metal named after the Norse god Thor that is said to have been a better alternative than Uranium (but we know which one won out). One gram has more energy than 7,396 gallons of gasoline and only 8 grams are needed for 100 years of fuel. Concept cars have been made by Cadillac and a company named Laser Power Systems. The LPS car uses the Thorium to power a laser that turns water into steam to drive a turbine electrical generator. Sounds like the ultimate hybrid vehicle!
