MIT engineers developed an atmospheric water harvester that captures water vapor and produces safe drinking water across a range of relative humidities, including dry desert air.

The system runs entirely on its own, without a power source, unlike other designs that require batteries, solar panels, or electricity from the grid.

“This is just a proof-of-concept design, and there are a lot of things we can optimize,”

My only concern with something like this is that it's still ripe for legionella pneumophila contamination (i.e. the bacteria that causes Legionnaires Disease). While the collection method seems safe, the tank is still a stagnant body of water, and I didn't catch how they managed to keep the drinking water safe when I perused the article.

Don't get me wrong, it's fantastic that they've identified a way to harvest water without electricity (which is what I think the title should have been), but you'll still have to boil the water to kill off any sort of issues related to stagnant water.

Great points you made there.

I don't know much about the bacteria that could develop in stagnant water but it certainly sounds like something to keep an eye out in relation to how this project evolves.

And I edited the title to include the no electricity part you mentionned.

Could it be chlorinated ?
