Someone commented that bacteria would still be in the resulting purified water. I can't see that. Wouldn't the bacteria in that case have to be reduced to vapor to be lifted up and co-mingle with the water droplets trickling down from the plastic?
BRAVO, Very Cool! I live where there is plenty of sunlight (Florida) and can hardly wait to try this! BTW, where did you get this idea? Or did you come up with it yourself?
Very cool idea when in the hands of conscientious people who are careful never to allow the resulting plastic string to wind up in a waterway or mingled with the topsoil somewhere. Earth is choking and good planets are hard to find!
Biogas Plant Using Kitchen and Food Waste
Sandy 1949, the smaller gas holding tank has had its top cut off and is inserted into the bottom tank upside down (so the full-diameter hole is at the bottom). The methane is lighter than air so it simply rises into the void of the upper floating tank. Awesome Instructable, Antonira! Having several semi-tropical acres of uncontrollable weeds, I'm imagining what I could accomplish with the combined gas produced by a dozen units like this!
