Proxima Fusion

A current-free stellarator is a type of magnetic confinement device that confines a hot, ionized gas in a toroidal vacuum vessel with external magnetic field coils. If the gas is sufficiently hot, hydrogen isotopes fuse to helium cores and neutrons, releasing a total of 17.6 MeV energy per reaction. As neutrons are not confined by the magnetic field, they deposit their energy in an actively cooled wall. This drives a standard heat cycle with a turbine to generate electricity, a mature technology. Proxima Fusion is already working on an integrated modeling framework to deliver a reactor relevant and cost-competitive configuration based on the concept of a current-free stellarator. By informing the modeling framework of engineering constraints (and vice versa), Proxima Fusion can ensure that their engineering design based on the optimized configuration can be built while massively decreasing expected manufacturing costs due to optimization for higher error tolerance.
