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.
