MetroVolt.

MetroVolt is the long form of the Kronos burner — the D–³He tandem mirror stretched to grid scale for cities and data centers. Same physics as Aegis, more of it.

Cities, data centers, large baseload

MetroVolt is not a different reactor from Aegis — it is the same tandem-mirror burner built long. Because the burner's gain and neutron fraction are set by plasma conditions and do not depend on length, stretching the central cell to about 1400 m simply scales the power up to grid class: net electric of roughly +2832 MWe.

It runs the low-neutron D–³He fuel at the Mode M closing point, converting charged fusion products directly to electricity on the open ends of the mirror. That makes it a candidate for the largest continuous loads — data-center campuses and city baseload — where its size is an advantage rather than a constraint.

MetroVolt is a later product than Aegis by design. Its economics depend on an abundant, affordable helium-3 supply that does not yet exist, so Kronos treats the MetroVolt fleet as honestly gated on that fuel rather than claiming a near-term grid price.
