Spacecrafts that harvest ice are not out of the ordinary, there’s even research being conducted about steam powered spacecrafts (steampunk spaceships anyone??). But I want to engineer a ship that uses water in ALL its shapes and forms for power, not just for propulsion. With futuristic tech available like a completed fusion reactor how would this hydro powered ship make the most out of the available water including its components?
I’d like to know more about the cycle of water in the ship so I can better depict the inner workings of the spacecraft. It’ll be interesting to see a complex water cycle in a spaceship.
Edit: The ship is designed for long lasting exploration and will most likely carry passengers, or can be modified to do so. Core elements of the ship include the fusion reactor, cooling systems, turbines, a hydroponic or vertical farm and the ships electronics like the autopilot and batteries. Thanks to electrolysis hydrogen and oxygen are also available to make the most of the resource. Additional water is harvested from commets and debris but the ship should be able to recycle its water. Water circulates throughout the ship and should have as many uses as possible.
