▲ 275 ▼ Engineers at MIT and in China develop desalination system which could produce freshwater that is cheaper than tap water (news.mit.edu) submitted 2 years ago by cypherpunks@lemmy.ml to c/technology@lemmy.ml 32 comments fedilink hide all child comments It looks like the paper is paywalled and not yet on scihub but i did find 38 pages of supplemental information with more details than the article.

For coastal people of impoverished or war-ridden locations with tainted or unavailable groundwater supplies, this is amazing if it becomes reality. Your normal isn't most people's reality. Clean drinking water is not ubiquitous. permalink fedilink source parent hideshow 2 child comments replies: [+] linearchaos@lemmy.world -11 points 2 years ago (1 child) Are you telling me you can't make a solar still out of a sheet of plastic a bowl and a hole in the sand at the beach? Because if you don't think that works we have no further need to communicate. permalink fedilink source parent hideshow 2 child comments replies: [–] BassTurd@lemmy.world 11 points 2 years ago (1 child) Hope much drinkable water are you generating with your sand hole and plastic? This thing can allegedly generate liters per hour. Enough to sustain a decent sized group of people. permalink fedilink source parent hideshow 2 child comments replies: [–] linearchaos@lemmy.world -2 points 2 years ago* (last edited 2 years ago) The numbers provided are qualified with "if they can scale it" up. So they don't even actually know that they'll get that rate. Edit: MythBusters did it They pulled a about a half cup an hour out of a 6-ft wide hole. Best case if you are engineering this you could put a frenzel lens in front of a pan of salt water your energy conversion would be like 99%. For using sunpower, The amount of water you're going to extract is directly related to how much energy you can collect. I'll believe their numbers when they actually bother to scale it. permalink fedilink source parent
