Hydrogen Engine Balance
Engines Are greatly welcomed. They have been fun testing, but at this point I find them more troublesome then they are worth.
Here are my thoughts on the mechanic:
1-Reduce engine capacity (1/10 of the massive tank is not even close to realistic)10,000L is sufficient, with a usage of maybe 5/10% of original (that makes worse efficiency from O2/H2 generator per power unit per kg ice, but makes it easier to use and manage)
ii-i: you could add a small H2 tank instead. tiny 1x1 or 2x2. The exact size/capacity is 3,200L per block (small blocks) , but taking into consideration realism in miniaturization, i'd say 2,500L for a 1x1 and 20,000L for a 2x2?
ii-ii: For the large, 277,777.77L/block so make a 1x1 @ 250,000?
2-Play with consumption. 1000L/s is insane. (large block, ALTHOUGH BOTH SIZES TESTED)
i: Its insane to have to use two O2/H2 generators as well to keep up effciency
ii: This kills use on nimble small ships
3-add O2 consumption (vent ability on planet, needs O2 in space)
4- Allow Engine to fill whilst offline
