I might be missing something, but the Carbon extractor and the Water Purifier are producing less than it tells in description.
I haven't checked the bigger ones, but the small ones are only converting at about 1% of the stated rate.
Fresh Install with only TacLS and its dependencies and Mechjeb2. Craft with no crew, water and oxygen tank, small Water Purifier and Carbon extractor, EC, and the storage of the converters full with CO2 and Waste Water. On Launchpad activate the Converters and warp for a day. 1.13 Oxygen and 0.01 water created - there should be a hundred times that.
Am I missing something?
