Distillation of urine with solar energy was one of the things we were taught in survival school when I was on active duty in the Marine Corps. This was decades ago, so it's not a new idea.
Thanks. What I had in mind was purity of the re-condensed liquid. By
the way, did somebody take a patent on turning urine into drinking
water by using solar energy. I am thinking about caravans in equatorial
deserts. An oasis with fresh water made from the urine left by previous
visitors.
Hei, it is time to start watching the France-Italy game in Berlin.
