Hydrogen Engine Tank needs tank behaviour
Right now, while the hydrogen engine has a tank, it does not actually have all the features a tank has:
- It has no stockpile option, making refueling at say, a base, needlessly difficult, especially if that base is using up hydrogen for other things at the same time.
- It cannot refill hydrogen bottles
- It only refills while its set to "On", meaning I can't refuel my engine while its not producing power, needed or not.
It also can't supply thrusters with hydrogen, so there is still a need for a smaller hydrogen tank as well. Nor can it otherwise pass its hydrogen to any other block - once its in the engine, its there to stay.
