The possibility of a nuclear-powered vehicle is not an idea reserved for only science fiction as it seems. A US company has stated it will have ready a nuclear-powered prototype vehicle on the road within the next two years.
A Connecticut company, Laser Power Systems claims to be developing a propulsion method in which thorium is used as fuel to produce electricity to power engines. Thorium is a super-dense element with the potential to produce large amounts of heat. According to LPS, one gram of this element can produce more energy than over 7900 gallons of petrol — 8 grams would be more than enough to outlast the vehicle itself.
The way thorium works is it uses small pieces to generate heat to produce a thorium laser. The laser would then heat water to power mini-turbines. It basically is a super-potent steam engine.
If thorium in fact replaces oil as the next source of energy for the planet, Australia is going to become the global energy giant as it holds 17% of the Earths thorium with 333,690 tonnes.
