Darpa won the contract to develop ‘Water Harvesting’. Since this is a military project the details are A BIG SECRET. It’s NOT sucking moisture out of the air. That much seems clear. Or as clear as anything coming out of the Pentagon. Salt seems to be involved. Hmmm.
The claim is that a ’20 foot machine’ will yield about 600 gallons of pure, clean water a day. And the system only requires 14 percent humidity. Which is why using it in a desert works fine.
Now, those of us who aren’t militaristic by nature will realize that such as system could also be one of the methods to get clean water to people trying to survive a natural disaster. Used in combination with something like LifeStraw (R) (for example), people in real need could be helped. Are you listening, FEMA?
Here’s a PDF of more details.
