The system can function in air with 20% humidity or less. But these 1,000 liter a day machines are not small, at around shipping container size.

I think technically what we call humidity is actually relative humidity, so it can go below zero. Ture humidity can't of course.

"relative humidity" is the percentage of water the air holds relative to how much it could hold, which varies by temperature. It can't go negative, though it can go over 100%.

I looked it up. It is something to do with how the sensors work. Under certain conditions they will report negative. Either way, the point was, I don't see this machine being able to do much if it needs around 20%...
