Are there any major non-federal projects exploring fusion current? And I say "non-federal" because I believe the Federales have a vested interest in delaying any advances in the field.
All the fusion projects are either national labs or university labs. Most of the funding is Federal. Actually a fair amount of funding is international, including European and Japanese. They would all like to have this answer, but inspiration is apparently not hastened by spending more money above a certain level. What is it now? $5 billion a year? Maybe not even that.
