An anonymous reader writes "Thorium, an abundant and radioactive rare earth mineral, could be used in conjunction with a laser and mini turbines to easily produce enough electricity to power a vehicle. When thorium is heated, it generates further heat surges, allowing it to be coupled with mini turbines to produce steam that can then be used to generate electricity. Combining a laser, radioactive material, and mini-turbines might sound like a complicated alternative solution to filling your gas tank, but there's one feature that sells it as a great alternative solution: 1 gram of thorium produces the equivalent energy of 7,500 gallons of gasoline."
