Re: I had a big pollytunnel

Yeah, it's just different trade off for yield and space used vs materials cost and the conditions they work in. With the electric condensers you can move the solar element wherever makes sense, the condensers can be more vertical, and the ground underneath could still be used for other purposes(garden, car park, whatever). But if the conditions are right, even planting trees can pull enough water out of the air to start surface streams flowing at lower altitudes.

I expect that as this takes off that the higher efficiencies they are shooting for will be realized by approaches that leverage both powered and passive elements(much like the cooling towers on the old power plants) and minimize land use.
