Does anyone know of any designs for DIY passive desalinators? My mum has a house on an island that doesn't have a natural source of fresh water (except rain of course), and it just occurred to me that a desalinator would be a fun thing to build there. Normally if there's a long drought she would have to have drinking water delivered by sea.
- ratsforhorses 5y agoI'm sure you'll get better answers but I really liked the idea of ventilating greenhouses with salt water.... could be a good way to get the extra liquid needs..a quick google found me this https://www.sciencedirect.com/science/article/pii/S0011916417302400 https://www.sciencedirect.com/science/article/pii/S001191641...
- Cthulhu_ 5y agoThe most simple ones ("survival" type, but it won't produce enough water unless you scale up) is spanning clear plastic over a pool of (shallow) salt water, weigh it down with a rock in the middle, and put a collector in the center underneath so the evaporated water runs down it. But I'm sure there's commercial solutions out there.
