The Low-Neutron Direct-Conversion Burner
A D–³He tandem mirror that makes electricity directly — low-neutron, disruption-free, modular.

Combining a low-neutron fuel (D–³He, 5.44% neutrons) with a linear tandem-mirror geometry and direct energy conversion (0.70) is a distinctive package: clean electricity without a steam cycle, no disruptions, and a length that scales to the job (55 m/440 m/1400 m).
It is a deliberately different bet from the mainstream single D–T tokamak.
Common questions
It runs D–³He in a linear tandem mirror, so it is disruption-free, converts energy directly at ~0.70, and scales by length into three product housings from one physics core.
Its net power is requirement-class: it depends on the plug reaching a density ratio near 16. Kronos labels it as such rather than quoting net power unconditionally.
