General Fusion is a Canadian company based in Burnaby, British Columbia, which is developing a fusion power device based on magnetized target fusion. The company is funded by a variety of investors.
Most MTF systems use magnets to compress a plasma. In contrast, the General Fusion fusion device under development injects a plasma mass, in the form of a compact toroid as the magnetized target, into a spinning vortex of liquid metal forming a hollow cylinder, which is then mechanically compressed to fusion-relevant densities and pressures, by anywhere from a dozen to hundreds of steam-driven pistons. As of 2017, General Fusion was developing subsystems for use in a prototype to be built in three to five years.
In 2018, the firm published several papers on a new design using a spherical tokamak as the plasma magnetized target, instead of a compact toroid. In extant references, it is unclear if this represents a major change of the original concept.
Highest paying job titles at General Fusion include Mechanical Engineer, Systems Engineer, and Engineering Design Manager
