  1. We also have much cheaper and much safer ways to use nuclear fission. These have been ignored but companies like Moltex and Thorcon are proving it can be done. Moltex is building a plant that will be fuelled with nuclear waste at a cost cheaper than natural gas. Grid connection expected before 2030. The designs are proven. The delays are purely regulatory.

  2. Nuclear fusion makes huge amounts of gamma rays. That will create tons of nuclear waste it’s also so difficult to contain the high pressures that there is no useful power remaining after the plant has fed its own needs. It’s nothing more than a means to extract government research money.

  3. Why are fusion engineers using a toriod shape chamber? If must be a nightmare to keep cool. How are we going to get enough tritium? It’s in seawater but at incredibly dilute ratios. Why do we insist on using fission reactors with a solid fuel and a pressurised core? That design works when you need irradiated fuel to build a nuclear bomb. It’s a curse when all you want is heat. It’s that curse which caused all of the accidents we have had to date. Alvin Weinburg designer of pressurised water reactors always said they were unsafe for scaling up. The accidents and ridiculous costs to mitigate the risks proved him right. Weinberg also invented the molten salt nuclear reactor. It has a core at atmospheric pressure, does not need powered emergency cooling and produces almost no radioactive waste. Proponents of fusion conveniently forget that fusion releases ionising radiation so it will also create some radioactive waste.

  4.  @Muonium1  how do they solve the energy demands of simply keeping the plasma contained? In short they can’t and when the supercooled magnets shut down the whole thing has to stop.
