Could there be a variant of the cargo rocket and buggies that instead of having an inventory, they have power storage? This would, for me, be great when I go to the asteroids or to mars. I was thinking that for the crafting recipe, either a energy storage module or storage cluster could go into the slot that the chests currently go into. I think there should also be something like a cargo loader/unloader to unload the energy. Tell me you think and if you would like anything different!
