content: After seeing all the water from air "busted" videos thunderf00t and Dave have released I should be an expert on this, but, am I missing something here, or is the Government been scammed out of close to a million dollars on trialing these things.It looks as though they have been in trial for over a year now around Australia, surely they have data to prove these are a poor economic solution.Where I saw the news storyhttps://www.abc.net.au/news/2020-05-07/remote-community-trials-hydropanels-to-shore-up-water-supply/12219818https://www.abc.net.au/news/2019-02-23/murrurundi-water-hydropanels-solar-technology/10836638The project on ARENA which states"It demonstrates how renewable energy can be harnessed to produce clean, great-tasting water and provide Australians with total drinking water independence"https://arena.gov.au/projects/source-hydropanel-demonstration/

content: I assume these technically work, but that's some extremely high price for little water.https://www.zeromasswater.com/fields/wp-content/uploads/sites/3/2019/12/Technical_1-Pager_2018.pdfhas the technical datasheet.So assuming you want to install these in arid and remote destinations, I'd expect no more than 2 litres per day per panel (or even less), so one panel is not enough to support (basic life support) one person.Gov site has some nice numbers:"Average daily water use ranges from as little as 100 litres per person in some coastal areas to more than 800 litres per person in the dry inland areas. The current average daily water consumption is 340 litres per person, or 900 litres per household. In addition, an average of 150 litres of water per person is used every day in the workplace by industry and commerce, community uses such as watering of public parks and gardens, firefighting and system leakage."Since you might want to use it in regions without water readily available, and at least minimum comfort, 100 litres per person is a good value - so this adds up to at least 50 panels per person, based on official avagere overall numbers it adds up to a crazy number of 250 panels.

content: I'd like to hear your numbers - how much (drinking) water per day is a minimum for western standards? I won't imagine showering or washing with water contaminated by lead, E.coli or whatever. (Little extra reading for lockdown: "Flint Michigan water crisis".)

Heavy metals etc can be removed by various processes, but typically another source would be found/piped/trucked for use. Biologicals are generally eliminated by chemical treatments, and that is where palatability becomes an issue for consumption, but minimal effect on washing/cleaning uses. In many (not even remote places) the water tastes bad but is within acceptable limits for consumption. Europeans consistently comment on the flavour of the heavily chlorinated tap water in Australia when visiting.Daily consumption requirements are in the order of 10l/day/person:"Water requirements, impinging factors, and recommended intakes"https://aloyoun.com.sa/documentation/nutrientsindw.pdf
