Desalination system could produce freshwater that is cheaper than tap water
news.mit.edu
A new solar desalination system takes in saltwater and heats it with natural sunlight. The system flushes out accumulated salt, so replacement parts aren’t needed often, meaning the system could potentially produce drinking water that is cheaper than tap water.

    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.

      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.

        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.
