Water Collector/Water Vapor gas

Water vapor is not visible, but it exists in your ship and it can stack up REALLY high. I think it stacks a bit like smoke, and smoke takes a lot of time to clear out.

If you have a serious backlog of water vapor, the reclaimers will be stuck at 5.0 drain for a LONG time. They drain a LOT of energy but they basically transmute energy rods into water, which is great. I recommend investing in a few solar panels to save resources in the long run.
