There’s news that the team continuing the late Dr. Bussard’s work on inertial electrostatic fusion have fired up their first test machine for the first time.
There is still a long way to go towards replicating Dr. Bussard’s results — true nuclear fusion that produces net power without any residual radiation — but it will be revolutionary if they do.
Current approaches to nuclear fusion may well turn out to produce net power, but they have the nasty habit of turning all their machinery radioactive.
