Well, after further research (http://pages.erau.edu/~ericksol/projects/futurspcrft/sp/intro.html), it seems that Skylab's molecular sieve system didn't convert the CO2 back into O2 (with waste C).  It just dumped the CO2 overboard, pretty much just like ISS currently does.\r\nSince the CO2 is just dumped overboard, I've removed the \"outputResources\" and adjusted the Waste tank accordingly.  Now instead of recycling CO2 back into O2 (and basically never using any of the O2 that comes with Skylab), now all that the extractor does is remove CO2 as it's generated.  I did leave the same 105% efficiency that we previously had so we can recover from time warp inconsistencies.\r\n\r\nI've also increased the electrical requirement for the extractor.  I can't find any documentation stating how much electricity was used to run the CO2 extractor, but I have to think it would have been more than 0.01EC/s (10 watts / hour)."},"comment":{"url":"https://api.github.com/repos/KSP-RO/RealismOverhaul/issues/comments/211538504","html_url":"https://github.com/KSP-RO/RealismOverhaul/pull/1146#issuecomment-211538504","issue_url":"https://api.github.com/repos/KSP-RO/RealismOverhaul/issues/1146","id":211538504,"user":{"login":"stratochief66","id":10169695,"avatar_url":"https://avatars.githubusercontent.com/u/10169695?v=3","gravatar_id":"","url":"https://api.github.com/users/stratochief66","html_url":"https://github.com/stratochief66","followers_url":"https://api.github.com/users/stratochief66/followers","following_url":"https://api.github.com/users/stratochief66/following{/other_user}","gists_url":"https://api.github.com/users/stratochief66/gists{/gist_id}","starred_url":"https://api.github.com/users/stratochief66/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/stratochief66/subscriptions","organizations_url":"https://api.github.com/users/stratochief66/orgs","repos_url":"https://api.github.com/users/stratochief66/repos","events_url":"https://api.github.com/users/stratochief66/events{/privacy}","received_events_url":"https://api.github.com/users/stratochief66/received_events","type":"User","site_admin":false},"created_at":"2016-04-18T19:22:02Z","updated_at":"2016-04-18T19:22:02Z","body":"Ahh true facts.

For\nexample, air moisture as well are urine reprocessing.
