CEO of Type One Energy and former head of General Fusion, bringing stellarator optimization and executive experience to the private fusion sector
Christofer Mowry is the chief executive officer of Type One Energy, a Madison, Wisconsin-based company developing a high-field stellarator fusion power plant. Before joining Type One, Mowry spent nearly a decade as CEO of General Fusion, one of the earliest and most prominent private fusion companies, where he led the Canadian firm through multiple funding rounds and the development of its magnetized target fusion technology.
Mowry joined General Fusion in 2011 and served as CEO through a period of significant growth. Under his leadership the company raised over $300 million, attracted investment from Jeff Bezos and other high-profile backers, and built a series of prototype compression systems at its Burnaby, British Columbia headquarters. General Fusion’s approach—compressing a magnetized plasma target using an array of pneumatically driven pistons—was mechanically unconventional and required Mowry to bridge plasma physics, precision manufacturing, and large-scale engineering disciplines.1
Mowry departed General Fusion and became CEO of Type One Energy, which is pursuing a fundamentally different magnetic confinement concept: the stellarator. Where tokamaks rely on a plasma current for part of their confining field, stellarators generate the entire confining field with external coils shaped into complex three-dimensional geometries. This eliminates the risk of plasma disruptions and enables inherently steady-state operation, advantages that have long been recognized but historically constrained by manufacturing complexity.2
Type One’s design draws on decades of stellarator optimization research, including work at the University of Wisconsin–Madison and Germany’s Wendelstein 7-X, the world’s largest operating stellarator. The company’s approach uses high-temperature superconducting (HTS) magnets fabricated with advanced manufacturing techniques to produce the intricately shaped coils that define a stellarator’s magnetic geometry. Mowry has assembled a team with deep roots in the stellarator community, including physicists and engineers who contributed to Wendelstein 7-X and the U.S. stellarator program.3
Type One Energy has raised significant private capital and secured partnerships with the U.S. Department of Energy. The company announced plans for a fusion pilot plant, positioning itself as one of the few private entrants pursuing the stellarator path alongside the more common tokamak and alternative-concept approaches. Mowry’s experience scaling a fusion startup at General Fusion, combined with the stellarator’s intrinsic advantages in steady-state operation and disruption avoidance, gives Type One a distinctive position in the private fusion landscape.4
Mowry’s career arc—from leading a mechanically novel compression scheme at General Fusion to championing an optimized stellarator at Type One—reflects the broadening diversity of approaches in private fusion and the growing willingness of experienced executives to pursue concepts that were once considered too complex for commercial development.
