Hi, I'm new here, but thought someone might be interested in my build of a portable Solar Still. I live in Los Angeles, near the coast. Our fresh water supply is "iffy" at best, requires the goodwill of Northern California to send it here, and requires the grid to be up, for pumping. It's one of the more severe vulnerabilities to living in LA if something goes wrong (there are many others, too). However we do have an endless supply of sea water! So I'm now on my third revision of a small solar still. Here's the progress to date. Goals are: (1) portable (2) easily stored and/or used as its primary components, a storage tub, a cookie sheet (3) food-grade throughout. I'm purposely compromising on size (many stills are 1 square meter in size, this is only .12m in size) realizing I'd need multiples if I were to depend on desalination as a source of drinking water. At least I can work out some of the design issues in miniature if the need arises to build a larger unit. In preparation, I read about a dozen academic articles on solar stills; this one combines an Iranian design with a Jordanian design. It gets the water tray (a teflon coated cookie sheet) up high where it will be directly in the sun (tho would work best if rotated throughout the day), and it lets the distillate fall into the bin below (a busser's tray, available at Sam's Club and the like). It required a wire-frame tray holder that was surprisingly challenging to fabricate, due to a necessary tradeoff of angles. The angles of the wire frame tray holder had to be complimented by the angles of the wooden tub holders. All of this would have been much easier if the tub had 90 degree angles on it, which it doesn't. So in the photos you see (1) the angled tub holders (which should rest on a piece of plywood rather than directly on the lawn, so it can easily be turned to the sun about 3x per day). (2) the tub in place. You can't see the reflective mylar on the back inside due to the shadows in this shot, but it should help concentrate sunlight. (3) wire-frame tray holder in place. This required several angles, one of which is to not allow the wire frame to actually touch the distillate. Another angle was required to allow the cover to fit. The wire frame is holding me up. I had wanted to try the still today but the paint on the wire frame has not fully dried from two days ago (stupid Rustoleum), so would impart fumes. Must wait another day, or however long it takes. (4) Tray in place. It's medium-dark grey standard cookie sheet, and I will probably add a black cloth to the bottom of it before pouring in the brackish sea water. In the center you see a bubble level, for getting it set up. (5) The glass cover with rubber gasket has been added. Not shown are the clamps used to hold the glass cover in place. As mentioned, the still is small, .12 meter area, so expectations must be similarly scaled. Most research is done on 1-square meter stills. The tub-still idea is viable only if you'd put out multiples. However they would be easily storable (stacking design) and a failure on one would not bring down the entire still, as on a larger one. Thanks for looking.
