Energy / Health / Shields

My idea is there should be an Energy Capacitor block, which basically functions like a hydrogen tank, but for power. There should be an additional bar under hydrogen level to indicate how much energy is stored. This energy would be able to be directed towards shields, thrust, weapons or just saved. Directing the energy could be done with 4 block actions on the hotbar for directing energy towards each of the systems or none. If energy is directed to shields, the shield would activate, draining a set amount of energy per second. Then for every point of damage taken to the shield, would deduct e.g. 1 / 1000 * mitigation% of energy per damage from the energy level. The amount drained while the shield is just active and not taking damage does not need to scale with the size of the ship to keep things simple, as it is minimal. If energy was directed to thrust, it would act as a booster of sorts that just drained a set amount of energy per second. If energy was directed to weapons, energy would be drained per second and each shot would deduct a point of energy from the bar as well. If the energy wasn't directed to anything, it would slowly regenerate depending on the capacity of the reactors of the ship.

I think this would create a more fun interaction during ship battles in the game and make room to introduce a new block (energy capacitor) with a unique system.
