Key Benefits of Helion’s Approach

  • Magneto-Inertial Fusion: By combining the stability of steady magnetic fusion and the heating of pulsed inertial fusion, a commercially practical system has been realized that is smaller and lower cost than existing programs.

  • ¬†Modular, Distributed Power: A container sized, 50 MW module for base load power generation.

  • ¬†Self-Supplied Helium 3 Fusion: Pulsed, D-He3 fusion simplifies the engineering of a fusion power plant, lowers costs, and is even cleaner than traditional fusion.

  • Magnetic Compression: Fuel is compressed and heated purely by magnetic fields operated with modern solid state electronics. This eliminates inefficient, expensive laser, piston, or beam techniques used by other fusion approaches.

  • Direct Energy Conversion: Enabled by pulsed operation, efficient direct conversion decreases plant costs and fusion’s engineering challenges.

  • Safe: With no possibility of melt-down, or hazardous nuclear waste, fusion does not suffer the drawbacks that make fission an unattractive alternative.



The Helion

Helion is the name for the nucleus of the helium atom. In practice, Helion refers to the stable He3 nucleus, in contrast to the other stable nucleus He4, which is usually referred to as an Alpha particle.
