Stupid question time, why not expose the sea water over a larger area and expose to sunshine? There's plenty of room in the UAE for this, somebody is even building a wall that could hold the water which could be dual purpose and act as cooling via evaporation...
- djent 3y agoLarger area than the oceans?
- SillyUsername 3y agoWe'll no but a super long wall facing south might do the trick...
- barelyauser 3y agoSearch for OTEC (Ocean Thermal Energy Conversion). Not necessary to build wall, just a big enough pipe to collect cold water from the depth. Then a special contraption will yield pure water from evaporation. Can be done virtually everywhere there is a deep enough ocean.
- 0xbadcafebee 3y agoI mean basically you're describing a solar pond (https://en.wikipedia.org/wiki/Solar_pond https://en.wikipedia.org/wiki/Solar_pond) or salt evaporation pond (https://en.wikipedia.org/wiki/Salt_evaporation_pond https://en.wikipedia.org/wiki/Salt_evaporation_pond). There isn't an easy way to recover the evaporated water from that process; you would effectively have to build an artificial enclosed environment and it wouldn't work as fast as exposure to the elements. Basically you would need a still (as in for alcohol) the size of 20 football fields. But sun power wouldn't be enough to power it fast enough to be practical. Maybe if you moved it into outer space...
- justsomehnguy 3y agoThis is how it is solved everywhere... but now you need to ship all this desalinetad water. And surprise! it's the second the most expensive part in the process.
