As long as its energy positive and cheap, this is where tokamak fails (ungodly expensive). If DPF fusion only manages a source-to-gird net energy of 110% its will still be worth its as long as its producing a few megawatts per cheap reactor. Tokamak is predicted to be producing 1MW per $25 million in its construction and research, coal power plants is at $1.3 million per MW (not include the price of coal) and if its works as claimed DPF could do $.2 million or less per MW! but yes monkeys could help.
