« on: 08/04/2021 23:14:28 »Another idea: you tether flying fridges in the desert. Fridges are solar powered, and are obviously open, so the ice can drop down. You fly them using anything: kites, airships, hot air balloons. Everything is tethered to the ground. If the fridges make too much ice, they will become too heavy for the kites/airships. As a result things start going down, allowing the ice to melt. Once the ice is gone, the kites/airships will go up again, and the cycle repeats itself.
How do you get the water into the refrigerators so that they can make ice?
I don't know how fridge work, but doesn't a cold surface (drops on a cold coke can for example) collect water from the air?
