that is the most powerful energy source known to man. >> michael mckubre says he has seen that energyhan 50 times in cold fusion experiments he's doing at sri international, a respected california lab that does extensive work for the government. mckubre is an electrochemist who imagines the creation of a clean nuclear battery. >> for example, the laptop would come pre-charged with all of the energy that you would ever intend to use. you're now decoupled from your charger and the wall socket. >> automobiles? >> same. potential is for an energy source that would run your car for three, four years, for example, you take it in for servicing every four years, and they'd give you a new power supply. >> power stations? >> you can imagine a one-for-one plug-in replacement for nuclear fuel rods, and the difference only would be that at the end of the lifetime of that fuel rod, you didn't have radioactive waste that needed to be disposed of. >> mckubre showed us just how simple the experiment looks. there are only three main ingredients. first, palladium, a metal in the platinum family. second,
