I'm thinking something that could be set up using trekking poles or sticks maybe... <br> <br> I'm toying with the idea of a there-and-back desert trip to the ocean, and it would be nice if I could carry half of the water I need for the whole trip, and purify enough seawater for the return trip while I'm near the ocean. But it seems like a long shot to end up with surplus water out of this thing without waiting around for days. <br> <br> I've googled some stills that can produce about a gallon a day, so the question is whether I could get comparable production with something really lightweight. tag:ask.metafilter.com,2008:site.92445 Mon, 26 May 2008 21:47:14 -0800 backpacking desert hiking solarstill water Dr. Send
