The world will need 2× more electricity by 2050 — but today's clean sources are intermittent, land-hungry, and can't deliver firm, always-on baseload at civilizational scale.
AI datacenters, electrification & industry drive relentless load growth.
Annual CO₂ emissions still climbing despite a decade of renewables.
No scalable, dispatchable, zero-carbon source exists at grid scale — yet.
ASTER builds compact fusion reactors the size of a shipping container — delivering firm, carbon-free, gigawatt-class power anywhere it's needed. No fuel scarcity. No meltdown risk. No emissions.
Hover each stage of the confinement cycle.
Deuterium–tritium fuel heated to 150 million °C forms a plasma where fusion occurs.
High-temperature superconductors cut reactor size & cost by 10×.
Real-time plasma stabilization now solvable with ML in microseconds.
2022–24 milestones showed net-energy fusion is physically real.
>$7B private fusion funding validates the emerging market.
Long-term PPAs with utilities & hyperscalers — recurring $/MWh revenue.
License the HTS + AI-control core to regional energy partners.
High-margin maintenance, monitoring & fuel supply contracts.
Blended target gross margin >60% at fleet scale, with capital costs falling 18% per doubling of installed units.
