and go somewhere. humid air diffuses and rises. warm air rises.
we might live in a box with an open top and a cool dry air pool
near the bottom and a fountain that turns off when the air near
the bottom reaches 60% rh, using diffusion and bouyancy to advantage,
vs the usual swamp cooler mixing. that would use less energy.
how much would it improve performance?
in more humid climates, we might have a greenhouse still on the roof
concentrating a desiccant pool, with condensation dripping down into
an enclosed swamp full of plants which evaporate water and cool the
house, as humid air rises back into the greenhouse.
