There are a number of fusion threads, but no ongoing coverage of progress in the space, which continues apace. It would be useful to maintain a summary of the current efforts and the high water mark performances achieved. Afaik, the rate of gain to date suggests that performance (measured by confinement time and temperature) improves by about a factor of 10 every decade. Researchers think another factor of 100 should enable workable fusion devices. The ITER schedule is somewhat off that pace, unsurprising as it was an example of UN style management until recently, but the Wendelstein 7 is reportedly working as expected and looks promising. Hopefully some of the more expert forum participants would chime in and keep us up to date.
