i was watching this show on the Science Channel and in it they talked about a new type of fusion reactor that is currently being built(construction started like 30 years ago). They said it will produce energy for entire world the same way the sun produces energy (fusing hydrogen). It's suppose to be something like 1000 times more efficient than current fusion reactors. They go on to say that water can be used to produce the energy. Will they just put water in the reactor, or will they split water to get hydrogen and put that hydrogen in the reactor? Can anyone explain how this reactor will work?
