In search for alternative propulsion systems and fuels, Cadillac is developing a car with portable nuclear reactor that will use 8 grams of Thorium and will weigh approximately 500 pounds.
This car can run for about 100 years and it is eco-friendly since thorium does not cause waste. Thorium is less radioactive metal than uranium and can produce so much more power. The energy that produces in excess can be directed to other electrical devices or even your house. Charles Stevens is working on the prototype version of the reactor and hopefully we can see in the next 2-3 years. Laser powered systems is developing the reactor.
