New stellarator design to boost fusion research, stays on all the time
Instead of relying on plasma currents like tokamaks, stellarators confine the plasma by specially shaped 3D magnetic fields.
In contrast, tokamaks and stellarators, which are doughnut-shaped devices, magnetically levitate hot ionized gases (plasmas) and heat them to temperatures hotter than the sun. The company maintains that with unique High Temperature Superconducting (HTS) magnets and liquid metal shields, it brings stellarators out of the lab and onto the grid. Another advantage is that stellarators can stay “on” all the time, whereas high-power lasers are pulsed and have low repetition rates, claimed Renaissance Fusion.
