Helion Energy uses fusion energy to provide pure, safe electricity. Helion's fusion generator elevates fusion (Deuterium and helium-3) fuel to ultra-high temperatures to achieve plasma conditions and directly obtains electricity with a high-efficiency pulsed approach. Magnets confine the plasma in a Field Reversed Configuration 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 100M degrees Celsius (150M already achieved). 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.
