Experts say we must maintain reactions for over a long period of time Also, devise a material structure to harness the fusion power for electricity We also need to research the tokamak and make fusion more attractive Once these issues are solved we'll have an unlimited source of energy Once these issues are solved we'll have an unlimited source of energy If we're able to solve an extremely complex set of scientific and engineering problems, fusion energy promises a green, safe, unlimited source of energy.

With the addition of tritium, the Z Machine's already neutron high upper limit will be pushed much farther, emitting 80 times the amount of neutrons. The Z Machine has long been used to provide crucial information for computer simulations that test the readiness of America's nuclear stockpile, and to recreate the conditions at stars and the cores of planets.
