After we left the still for 2 days, we check the water level in both trays. The water evaporated out ~ 1 cm height(~0.8 L). So the rate is about 0.5 cm per day (~0.4 L/day). Our target is about 3L/day, so if we can’t increase the evaporation rate, we would need to increase the…
Solar still: Add the output pipe and glass
We used PPR pipe for the drain tube, cut it in half with a hand grinder then sanded it clean. We drilled a hole in the side to insert the pipe through. then we screwed the wood to support PPR pipe. The pipe needs to slope down to make sure that water will not get…
Solar still : continue assembly
We painted the outside with weatherproof paint, inside with black to absorb heat. After we left it for a day to dry, we added a bolt lock and EPDM (the black foam stripon the last image) for sealing the lid.
Assembling the Solar Still
Today we screwed the wood parts together. We used EPDM insulated rubber (Link) for the base insulation:
Building a Solar Still
We stumbled across this page on Mother Earth News: https://www.motherearthnews.com/diy/home/how-to-make-a-solar-still-ze0z1209zsch So we decided to give it a try. We get a lot of sun here on the land… Today we cut all the wood parts
