Open question

What has the technology itself been shown to do, at what scale and under what conditions?

  • Not established in reviewed sources: Any demonstration of electricity recovered from fusion on Polaris
  • Not established in reviewed sources: Any measured energy gain (Q) figure from Polaris
  • Not established in reviewed sources: Operation on deuterium-helium-3, the fuel Helion says it will use commercially
  • Not established in reviewed sources: Independent replication of the February 2026 Polaris results

Evidence detail

Target: field demonstration reported, Date not disclosed

Polaris goal restated as 'electricity from fusion' (part of the fusion energy recovered onto its capacitor bank), no longer 'net electricity'; no date given; as claimed by Helion

A stated target, not something that has happened. It does not set a state. Targets can move; earlier and later ones are both kept.

“Today, we prefer to direct focus to the more concrete goal of Polaris: to demonstrate electricity from fusion, where we show we made fusion energy and converted a portion of it to electricity on the capacitor bank.”

What this does and does not establish

An exact passage match shows the source says this. It does not prove the underlying claim is true.
