Helix-0 Test Stand
First in-house REBCO coil sustained at 20 T, full operating field, with active quench detection — validating the confinement geometry the compact reactor design depends on.
Overview
Wherever there's a gradient, there's power.
Segal Energy runs four coupled programs — fusion, geothermal, bio, and resources — on one simulation stack and one rule: return more energy than you spend, and more matter than you consume. The star, the mantle, and the rainforest's own chemistry, engineered into firm, carbon-free electrons.
Every program is optimized for energy returned on energy invested — confinement efficiency, capacity factor, drawdown, fuel and mineral recovery. A source that needs more energy, or more scarce matter, than it makes is not a source.

Capabilities
FUSION
Segal Fusion
Magnetic-confinement fusion. Plasma simulation compiled to real-time control, disruption prediction inside the latency budget, 20 T REBCO magnets — driving toward repeatable net-positive gain, not a single demonstration shot.
GEOTHERMAL
Segal Geothermal
Deep and supercritical geothermal. Closed loops where rock allows, engineered reservoirs where it doesn't, and directed-energy drilling research toward depths where one well does the work of dozens.
BIO
Segal Bio
Algae biohydrogen and carbon drawdown. Photosynthesis run at industrial density in closed photobioreactors — hydrogen straight from sunlight and water, with measured CO₂ removal.
RESOURCES
Segal Resources
The connective tissue. Recovers fuel, lithium, materials, and carbon across fusion, geothermal, and bio — so every program returns more matter than it consumes.
Case Studies
Closed-Loop Thermal Bore
Closed-loop conductive heat harvest demonstrated, with measured output matched to the Subsurface Twin's prediction — firm heat with no fracturing.
Bench Biohydrogen
Measured hydrogen evolution from an engineered strain against a control culture — biophotolysis demonstrated, yield characterized.
Direct Lithium Extraction Pilot
A DLE skid on geothermal production brine measuring selectivity and uptime at temperature — by-product minerals recovered, not mined.
