I think comments are missing the point: one of the companies listed in article, Helion, is about to switch on a machine to demo net electricity production from fusion. Why would that be possible? Because they don't go on yet another fancy way to boil water to run a steam engine. They do direct energy conversion. In a fusion reaction energy is mostly released as kinetic energy of particles. Their fusion reaction is aneutronic, ie with few neutrons. That means that the energy is released as movement of charged particles. By definition this is an electric current. This current is directly captured by induction in the coils and sent to grid. If their 2025 experiments go well, in 2028 they will start selling electricity to Microsoft which whom they have a power purchase agreement. Thanks to the simplicity of their machine, they aim at a cost of 10$/MWh, competitive with solar. Their 50MW generator is shipping container size and be built in a factory by the dozens. Ok, they may fail, they could also succeed though. Worth watching.
