Good day!
i'm trying to create a simple simulation of electricity production and environmental usage of water and oxygen to be used on a space capsule or base.
Basically... on one side there is the fuel cell, with 2 ion engines using each LOX and LH2 and producing let's say...5 kW each (10 in total), and a 3rd ion engine outputting water to a water tank. Then, in the pressure vessel of the capsule there are 2 more ion engine, one "burning" water taken form the tank simulating drink and cooling consumption, and the other burning oxygen, to simulate breathing from crew. So the Oxygen tank will be drained both by fuel cell and crew.
Do you have any suggestion. for the momento no Vizzy is used, because i'm not good at it yet.
this is a simple scheme...

This is a really useful concept, there should be more of this
