A quantum of water

It was pointed out to me that drinking water is becoming a more finite resource globally. My initial reaction (from living in Ireland, where it literally falls from the sky almost every day) was “not around here it isn’t”. But then I was reminded that there’s wide scale pollution of the water tables, problems with existing drinking water delivery systems and while it hasn’t seemed likely for the last few years, every once in a while, a drought could cause serious problems. This is exacerbated by the fact that we do little as a nation to store rain water for non-drinking purposes.

So I was interested to see news of this device. I wonder how it would compare on John’s power consumption table. While it would be a great solution in countries where there is little water in the air, Ireland has plenty of it. I’m sure there is more discussion related to this.
