Just a small suggestion/request- impact shield (mainly for asteroids) but could include ship collision that gently forces two objects away from each other however, uses a significant amount of energy only when the collision is taking place. Pretty much what I'm getting at here is the shield only deploys when a collision happens, so a short burst of high energy usage (could even suck energy straight from the battery).
I'm sure at this point anyone reading this prob gets what I'm trying to describe. anyways just a suggestion :) thanks for checking it out
