Simple enough mod.
Using the amazing Cryogenic Engines and Planetary Base Systems together works wonders, until you find that you can't use liquid hydrogen for Sabatier reactions, or harvest hydrogen from a gas giant to refuel your nuclear engines. This allows the 1.25m and 2.5m Convert-O-Trons to compress hydrogen into liquid hydrogen, evaporate liquid hydrogen in a controlled procedure, and process hydrogen gas from ore.
