Zero Mass’ solar panels turn air into drinking water

  1. Journos who cover science and technology topics really should have at least some background in science and technology. If you want large volumes of fresh water and nature isn't providing it, reverse osmosis desalination of sea water is by far the cheapest way to get it, even if you have to pump the water hundreds of miles inland and thousands of feet above sea level.

  2. Seems like an over-engineered solution. A simple 60sq ft rain roof with a gutter could collect 465 gallons/year or 5 liters per day of rainwater even in Arizona (much more in other places). It's just a matter of storing it when it falls. A 300-gallon water reservoir is only like $300, 60sq ft metal roofing, gutter and PVC pipe would be like $90. So for $390 you could have access to the same amount of clean renewable water, it would just take slightly more surface area. It would take out the variable of solar power as well.

  3. 👍🏼 nice. Solid tech for those of us that live off grid , in the desert where the water table is 350+ below ground, costing about $80 per ft to have drilled with casing, putting a well at 28,000$ to drill on the low end, before pump house ect, my neighbor spend close to 65k on a well, before putting the pumphouse in, so $2500 is totally reasonable under those conditions not to mention it opens up the prospect of undeveloped real estate that can be found relatively cheap. We also catch water as well, 1” of rain =.6 gallons of water, but that also gets pricy trying to design a catchment that has the surface needed for both domestic and irrigation, and the quality is always questionable without a solid filtration system that is also optimized for solar use which can easily run $500 and up. I’m guessing most folks knocking this as being “an expensive dehumidifier” have never actually tried to run a dehumidifier (or any other 750 Watt appliance) off of solar panels. You would likely need between 2-3KW array plus a sizable and expensive battery bank just to run a dehumidifier for 12 hours, so this looks Like a much more efficient way, if you were to add up the cost of upsizing your solar system to acomedate a running at least 12 hours per day. A friend has another similar system as this by a company “air to water” that plugs into a 110 volt outlet, also about the same price , both MUCH more efficient that a standard 750 watt dehumidifier, so yeah, $2500 is actually a drop in the bucket so to speak when considering the cost of developing a parcel off grid, and water is absolutely the most essential resource for off grid living.

  4. There's several ways of making water in a survival situation just using a large plastic bag. You can produce drinking water using the plastic bag where there trees or no trees. Works on the same principle this expensive system. For your home there's plenty of water purifiers and active carbon filters to provide suitable good tasting safe water for drinking/washing.
