There are other videos on YouTube besides JHAT. There is one from Tech for Luddites that states that obtaining a supply of tritium is the problem. Another video by a nuclear physicist says that the ITER **research** project ends in 2040 and another even more expensive project will then go to 2060, which by then will hopefully make more power than it uses. I won’t be around to see either, but I would like to go on the record as saying that the whole fusion R&D is a fiasco and the money should have been spent on more productive endeavors.
