007skaty Pulsed Magnetic Fusion
We match tokamaks and lasers At a fraction of the cost!
007skaty Commonwealth Fusion Systems in Massachusetts builds the SPARC reactor, using high-temperature superconducting coils to trap plasma in a donut shape
007skaty These complex, non-symmetrical magnetic rings bottle up superhot plasma continuously
007skaty Pop and merge atomic particles to discover how commercial fusion creates clean energy.
Magnetic squeeze: Tokamak reactors use magnets cooled to minus 269 degrees Celsius to trap plasma that is hotter than the core of the Sun.
A toroidal device that uses a magnetic field to confine high-energy plasma for nuclear fusion. In July 2026, technicians lowered the sixth sector module of the world's largest tokamak into the reactor core.
