This instructable is missing vital, or rather deadly information:https://www.instructables.com/id/Drink-Your-Own-Pee---survival-guide/i posted a comment on it, but i doubt anybody will read it. if it is already contained in the instructable, and i haven't seen it, please forgive me.: HeLLO!!!!! I lnow i am VERY late with this post, and i hope someone still reads it.NEVER DRINK URINE! EVER! WhY? well, for one, fresh urine contains no bacteria, unless you suffer from bad kidney disease, in which case, you probably couldn't pee anymore.so why not drink it? because ALL TOXIC WAIST of your body leaks into your urine. those remain inside this primitive distillation device on the soil ,as mineral salts, the water being evaporated and recondesed on the foil, thus recuperated. so, this thing is basically a sun powered water distillation thingie. in emergency situations, you can distilate your urine by other means too, to drink water out of it. just DON'T DRINK URINE, NOT EVEN BOILED. ESPECIALLY NOT BOILED. the water getting evaporated by boiling, the urine increases the concentration of toxines. you can only boil it up to collect the steams, which condense into water. that's what you wanna drink.
