Thorium lasers: The thoroughly plausible idea for nuclear cars

Some proposed technological innovations seem so far out that they are easy to reject out of hand. But sometimes, a new idea has a kernel of plausibility. Such is the case with a new project to develop a thorium laser power generation system that its creator says could provide electricity for the grid, stand-alone power applications and even cars.

Charles Stevens, an inventor and entrepreneur, recently revealed that his Massachusetts-based R&D firm, Laser Power Systems (LPS), is working on a turbine/electric generator system that is powered by ?an accelerator-driven thorium-based laser.? The thorium laser does not produce a beam of coherent light like conventional lasers, but instead merely heats up and gives off energy.

Thorium, a silvery-white metal, is a mildly radioactive element (with an atomic weight of 90) that is as abundant as lead. It is present in large quantities in India and is a much-touted stand in for uranium in nuclear reactors because its fission is not self-sustaining, a type of reaction called ?sub-critical.?

The idea has energized the small but active thorium community, which holds that it is the answer to our clean energy needs because it could, effectively, power a car forever. The new technology ?would be totally emissions-free,? Stevens said, ?with no need for recharging.? [Read More...]
