WaterSeer™ condenses pure water from the air without power or chemicals. It is green, sustainable, simple, low-maintenance, easily deployed and scalable for any community. VICI-Labs worked with UC Berkeley and the National Peace Corps Association to develop a device that yields up to 37 liters of pure water a day! A WaterSeer™

Amazing if true.
Scam.
Saw a portable version of this last week.
I can condense pure water all day long on the outside of a glass of ice water. The missing part of the equation is my electric bill to make those ice cubes.
Scam. Violates the laws of thermodynamics. Even Obama couldn’t repeal them.
Here is the article I read last week about a product called Fontus: http://www.craveonline.com/design/990759-fontus-self-filling-water-bottle-scam-evidence-suggests
This works. The video says under ideal conditions 37 liters a day. Most places will not be ideal condition places. The more moisture that is in the air, and the warmer the areas are, the better your chances at hitting the ideal. Deserts will not be ideal condition places.
It says the water is not condensing from relative humidity, but simply from the difference between hot and cold.
“Hot” and “cold” cause condensation from relative humidity, so something seems amiss with their explanation.
How is it Violating the laws of thermodynamics?
Just uses wind and earth’s coolness it seems.
Dew tell.
Violates the laws of thermodynamics but, Obama can solve that with an Executive Order and create a new law...
.....but he could spend 500 million taxpayer dollars
Haha
There’s a lot of exaggeration here- “the daily minimum, 7.1 cups of water needed to survive.” A 170 pound person is supposed to drink 85 ounces of water daily to avoid dehydration.
The basic theory is one that looks sound at first glance, but doesn’t hold up under scrutiny or real-life testing.
The theory is, things that are underground tend to be a constant, cool temperature. Water condenses at cooler temperatures. Therefore, pump air underground where it’s cooler than aboveground, and the water will condense out and become usable.
The reality is, pumping air underground causes the ground in that spot to warm up, until it matches the average temperature of the air being pumped in. End result: it might condense water out of the air for the first few hours, or even a day, but then it stops working.
(It also only works if the air is warm enough and carries enough humidity.)
Parts of that design look like something I’ve been toying with that uses peltier devices to achieve the right temperature, but the ground itself will never do the trick. And even then, the one I’ve been toying with is meant as a low-power dehumidifier, not a constant water source.
Interesting concept. I suppose it’s doable in some places. Probably depends a lot on the dew point of the air.
Considering what it costs to dig a well, this could be economically viable if it produces enough.
I’m skeptical that they are able to filter the air and still maintain adequate flow and if they don’t filter it, then it’s not going to be pure - it’s certainly not the equivalent of distillation.
An alternative idea might be to put a reservoir of fluid below ground, then pump it up to a condenser which would be easier to maintain and clean above ground. Could be coupled with a fan to run when there isn’t any wind.
I also suspect that the ground might eventually warm up surrounding the device, limiting it’s effectiveness.
Just some thoughts.
Here in WV, we have plentiful water in springs and creeks, but wells are often very deep and very expensive. But the air is moist most of the year and dew in the morning is nearly always plentiful. So it might make sense if it were cost effective and you didn’t have another source on site for water.
Adaptation of the old pit-style solar still. Boy Scout Field Manual from the 60’s.
“That’s 3,285,000 people a year. Is that possible ? Sad if it is. “
It seems very high. If that was true, the arid countries without water would have no people now.
That figure is probably a combination of disease, starvation, lack of water, war, etc. Either way, the number still seems very high.
