10⁸ K — The plasma · Kairon Fusion
A star,
contained.
A compact high-field tokamak, and Solis-1: the pilot plant designed to put fusion electricity on a grid.

10⁰ — In plain language
Safe by physics, not by promise.
No chain reaction
If anything fails, the plasma cools in milliseconds and stops. Nothing runs away.
Physics · all tokamaks
Grams, not tonnes
The vessel holds about 2 g of fuel at any moment, less than a paperclip.
Solis-1 design · illustrative
Short-lived waste
Activated components decay to recyclable levels within about 100 years. No long-lived spent fuel.
Design target · forward-looking
Zero carbon at the stack
No combustion, no CO₂ from generation. Lifecycle study in progress.
Lifecycle study · In testing
10⁰ — Next step
Reserve power from the first fusion plant.
Registering is non-binding. You get quarterly program updates and first access when offtake agreements open.
