the swamp cooler panel seems more durable than rotating blades, maybe*. If i were going to desal it'd be with solar; which seems inefficient but one could precipitate "CO2" out of the water as calcium carbonate during the same process. Emergency water supply for tropical weather aftermath, during the quiet season park upstream from a coral reef that's in danger.

*edit: although window and wall unit HVAC use the blades to fling water around so the condenser gets the coolest possible air
