I agree, but perhaps instead have varying types of generators? The current one would be balanced, while there could be a new one, perhaps fission that gives a lot of power but has little ability to store much charge. Then a third that gives little power generation but stores an immense charge, I don\'t know what power gen could do this though.
On a side note, I would like to see solar panels as well. Perhaps they give better energy than the basic generator but are restricted to stationary objects (as it would be \"too difficult and innefficient to use them on a ship, especially when in deep space\").
Stations could also benefit from energy storage, I actually prefer dedicated energy storage blocks vs generators that store it automatically. Makes the ship more customizable and gives the player the ability to focus on generation or storage without needing a new generator types (like I suggested at the start of this post :P).
