"The fuel used to power the reactor would be the hydrogen isotopes in water – and as we have a nearly unlimited supply of water at our disposal, these reactors could run indefinitely. What's more, they produce very little in the way of waste."
However, there are clearly unacknowledged dangers. Also the magnets are so huge and powerful that it seems impossible to size them in a functional way at this point. I continue to think researching zero point energy is preferable for safety and functionality.
