I've seen this photo, and can't see where it goes either. Maybe a crank of proper size will achieve required torque, I don't know. PUR06 pump is harder to press than a small bicycle pump. Wind must be strong and tripod anchored pretty well to sustain it. >Pretty big contraption for > a kayak. Rube Goldberg would be proud. This is one of his "double use" ideas. Tripod looks like fishing poles (or spare compostie rods from foldable kayak), anyway something that can be completely dismantled. Doesn't appeal to me when I move my camp everyday, but OK for a 2-days stopover. > When I looked into automating desalination (none too seriously), my > back-of-the-envelope calculations told me I couldn't power it with a > reasonable sized solar panel and battery combo. I don't think reasonalby sized solar panels and battery will be enough. 12V electrified PUR35 needs a lot of current according to specs, and PUR06 will still need a lot. After I've got an old discounted 06, I thought to get an old 35 (without electric drive) - 1 hour of daily pumping with 35 is.. well... acceptable on the last week of 3-weeks trip without any freshwater nearby, or on unexpected delay caused by the weather or anything else. (2 weeks water supply can be carried in Drom bags). But 3.5 hours with PUR06 - not to my liking, thanks :-). So I just try to keep it down to 2 weeks (or paddle closer to freshwater sources, which is often feasible in my area).
