the design for a new solar desalination system that takes in saltwater and heats it with natural sunlight.
The configuration of the device allows water to circulate in swirling eddies, in a manner similar to the much larger “thermohaline” circulation of the ocean. This circulation, combined with the sun’s heat, drives water to evaporate, leaving salt behind. The resulting water vapor can then be condensed and collected as pure, drinkable water. In the meantime, the leftover salt continues to circulate through and out of the device, rather than accumulating and clogging the system.
Neat.
The team envisions a scaled-up device could passively produce enough drinking water to meet the daily requirements of a small family.
Hmm.
The last paragraph is cool too though. A single device for a household that produces enough water would be big for many communities. The only real question here is how complex and expensive the device is.
I wonder whether that’s safe enough considered there much shit in salty water than just salt but judging by the fact it’s condensing I guess that’d mean yes?
Most of the shit will remain down with the salt, as they’re too dense to flow upwards with the water vapor.
Btw, that’s pretty much distilled water, right? While drinkable, it’ll be lacking some needed minerals, no?
No. You can get those minerals from your food. It is safe to drink distilled water. But there is a lot of misinformation about distilled water, I have even had people tell me it can kill them! Water is water. Get your minerals from food.
