Everyday DIY

You can pull half a liter of clean drinking water out of thin air overnight — for $12 in parts.

Mesh, PVC pipe, zip ties, a gutter section. Tilt the frame 15–30° into the wind. As the air cools overnight and hits the dew point, water condenses on the mesh, rolls down by gravity, and drips into the trough.

People in coastal Chile, the mountains of Morocco, and rural Ethiopia have done this for generations. The Incas built stone structures specifically to catch fog. The atmosphere holds roughly 37 quadrillion gallons of fresh water at any given moment — more than every river on Earth combined.

Half a liter is what I got on an average night. In humid or coastal climates, the same setup pulls 1–2 liters. Scale it up and you're covering a family's drinking water. No grid, no bills, no permission needed.

Old knowledge, $12, one afternoon.
