A US company has announced it's developing a radioactive steam-powered car engine. According to the company, the engine would be a turbine powered with steam heated by lasers powered by the mildly radioactive element thorium. According to the company the engine would go decades between refuelings, and be perfectly safe.

According to me it sounds like a load of hooey, but I do wish whichever venture capitalists that are under-writing this venture loads of luck. I have a feeling they're going to need it.
