Helion Energy uses fusion energy to provide pure, safe electricity. Helion's fusion generator elevates fusion (Deuterium and helium-3) fuel to temperatures greater than 100 million degrees Celsius to achieve plasma conditions and directly obtains electricity with a high-efficiency pulsed approach. Magnets confine the plasma in a Field Reversed Configuration (FRC) and speed up two FRCs to 1 million mph from opposite ends of the generator. When the FRCs collide in the center of the system, they are further compressed by a strong magnetic field until they reach fusion temperatures greater than 100 million degrees Celsius (9 keV). At this temperature, the deuterium and helium-3 ions are moving fast enough to surpass the forces that would otherwise keep them apart, and they fuse. This emits more energy than is consumed by the fusion process. As new fusion energy is generated, the plasma enlarges.
