Technologies advancing very quickly nowadays and new technical solutions seem detached from Sci Fi movies, electric cars, cars with engines on water (whose development is blocked because it would destroy the whole industry based on gas and crude oil) and lately the thorium car, which could result in a autonomy up to 100 years of use without refuel the car …
A company called Laser Power Systems has created a concept whose engine operates on the basis of thorium. Being radioactive, the team used very small pieces to build a laser that heats the water and produces steam. This steam is converted into energy by means of a turbine.
A single gram (0.03 ounces) of thorium produces more energy than 28000 liters (7400 gallons) of fuel, while an amount of 8 grams (0.3 ounces) would be sufficient to propel a car for 100 years.
