A water-harvesting jacket developed at the University of Texas can collect up to 900 millilitres a day from ambient air, but the captured moisture still has to be heated before it becomes drinkable
Reports of a Swiss materials lab's prototype jacket that harvests close to a litre of drinking water per day from ambient humidity sit on top of a decade of peer-reviewed work on passive sorbent hydrogels — including an MIT panel that produced up to 161.5 millilitres a day in Death Valley with no electricity at all.
