3.) Does Starship Flow Capacitors affect this power drain?
It says it affects things that drain power, do Polaron weapons count?
Actually, it very much seems to have an effect - I don't have the skill trained myself, but sticking a rare Flow Capacitor Mk X console on my ship (+24 to Starship Flow Capacitors) improves a Polaron weapon's power drain from 25 to 28. It does the same to Tetryon Glider, and I imagine it does the same for actual Tetryon weaponry as well.
