Helical Fusion is developing helical-type fusion stellarator reactor. Their helical design keeps incredibly hot ionized gas contained steadily by itself, eliminating the need for external electrical power and allowing operations to run longer than with rival technologies. The company has finished testing a superconducting magnet that could work on a commercial scale. This marks the first time a commercial-scale coil has operated successfully under such conditions. The company plans to construct demonstration equipment by the decade's end. During the 2030s, Helical Fusion aims to launch its first pilot facility operating continuously while generating more power than it uses.
