ECLSS Sabatier Loop Optimizer (2D)

A spacecraft's oxygen-recovery loop couples two real reactions: water electrolysis, which makes breathing oxygen and a hydrogen byproduct, and the Sabatier reaction, which reacts that hydrogen with the crew's exhaled CO₂ to recover water. This 2D diagram lays the loop out as an interactive flow map — gas and liquid streams animating between the scrubber, reactor, water tank and electrolysis unit — paired with live efficiency and molar-flow charts, so you can tune electrolysis current, reactor temperature and catalyst age to chase the ideal 4:1 hydrogen-to-CO₂ ratio at peak conversion efficiency, watching loop closure, vented mass and water balance respond exactly as the governing mass-balance equations dictate.
