They sure do assume that. So far, there has been practically no evidence that cold fusion produces dangerous radiation. It may produce tritium, but overall I expect it will probably produce less nuclear waste than today's coal fired plants. Granted, coal put radioactive garbage mainly in places close to the plants, which are located in poor, rural districts. Whereas a cold fusion engine may leak tritium in your house. Tritium can be contained. It is contained in tritium-powered "exit" signs. - Jed
