Thea Energy Unveils Helios Stellarator Power Design
New Jersey-based Thea Energy on Monday unveiled a preconceptual design for Helios, a stellarator-based fusion power plant compatible with current manufacturing and maintenance infrastructure. The design uses 12 large and 324 smaller programmable planar magnets controlled by software and AI to compensate for manufacturing irregularities, and targets 1.1 GW thermal (390 MW electrical) with an 88% capacity factor. Thea plans a demonstrator Eos startup by 2030.
Key Points
- 1Introduces stellarator-based Helios design using 12 large and 324 small programmable planar magnets
- 2Claims software and AI control can compensate manufacturing defects, avoiding need for extreme magnet precision
- 3Targets 1.1 GW heat and 390 MW electricity, 88% capacity factor, aiming $60/MWh costs
Scoring Rationale
Innovative engineering and AI-enabled control provide practical path to fusion, but company-level design lacks independent verification.
