> follow up plant, DEMO [2], should produce electricity (750MW) If it will ever be built and then go online. Which is highly unlikely given the slow progress of ITER and its very difficult problems - some it even does not try to solve. Like getting enough Tritium: https://www.science.org/content/article/fusion-power-may-run-fuel-even-gets-started https://www.science.org/content/article/fusion-power-may-run... 750MW (again using thermal energy, which is probably not the future of electricity production) from such an expensive & complex device? Probably you would need pools of several fusion power plants, since it is unlikely that one fusion power plant will run for a longer periods of time. Maybe a pool of six would provide two running (just a wild guess). The technical problems will be huge and the costs gigantic. I can't imagine how this will be competitive when in production (with outputs in tens of Gigawatts, to make any impact) in 2060 or later.
