"Armor Regeneration"
- stores unlimited points,adding "value 2" amount everycombat turn.
- at the end of every combat turn SE4 scans through the component list, and repairs any damaged component with fewer hitpoints than the currently stored amount (subtracting from the storage as it repairs)
- if all copies of ANY component with armor regen ability are destroyed, all "armor regeneration" on the entire ship is disabled until the end of combat

RE: Crewquarters repair ability.
I meant using the "once per game turn" repair,not the armor regen ability. In P&N, the lifesupport given by the "Living Ships" racialtrait does 1 physical (ie. "repair bay" style) repair per month.
If you want to describe it as "memory metals", and make it so that the ship can "pull itself together" no matter which components happen to be destroyed, then add the component repair ability to vehiclesize.txt

RE: energy sappers.
how about making a reload increasing damage weapon, give it a +500% accuracy bonus, -1000 supplies used, and a balancing reload time. You'd be draining power from their weapons, and would hit 99% of the time, avoid the "get supplies out of empty space when you miss" thing.
