What the title says, effecfively a mini-TEG, which accepts plasma and turns it into power, based on some stuff ( KPA, Heat , Contaminants ) Cold gas = Less power, longe lifetime, Hot gas = More power, longer lifetime.
Tritium version would rival 35 core AMES
They also explode with the force of a pre-nerf charon if destroyed while having plasma/trit gas in them.
Trituum version would likely be close to the explosive force of a Nuclear Option ( although nerfed. )
A neat way to power atmos ships, without the supreme nerd shit like the TEG or Supermatter.
