This Car Runs For 100 Years Without Refuelling – The Thorium Car – Science Vibe

"Science is a way of thinking." Carl Sagan Share Us. If you have a car that is powered by Thorium, you would never need to refuel it, because the vehicle would probably burn out long before the chemical did. The Thorium can last for so long, in fact, that it would probably outlive you. A company called Laser Power Systems has created a concept for a Thorium-powered car engine. Thorium is a radioactive element, and the team uses bits of it to build a laser beam that can heat water, produce steam, and then power an energy-producing turbine. It’s one of the densest materials on the planet and just a small sample of it packs 20 million times more energy than a similarly-sized samp ... | Read more at
