Solar-Power Water Purifying Still

Solar-Power Water Purifying Still

“To make a solar still of this type, you’ll need to make a box out of plywood. You can’t see it well in the picture, but the white line at the back of the still is a door, which flips down to allow the water pans to be placed inside it. For water pans, I used two large rectangular Pyrex dishes. To accommodate them, the inside dimensions of the box are 19 inches wide by 23 inches long. I was careful about this measurement, as glass commonly comes in pieces that are 24, 36 and 48 inches. Had I made the box just a little bit bigger, I would have needed to buy a 36-inch piece of glass and waste most of it.”
