I am building a passive solar "caveman" still, and once it is completed, I will provide more information.

Basically, it is a circuit of copper pipes which "pre-heat" water which is dropped onto a track (rain gutter with a short lip) within a larger black PVC pipe. The water on the track evaporates and condenses within the black PVC, where it accumulates and drops into a holding tank or bucket.

The only power requirement would be tying into a 12v system with an RV water pump, which can be accomplished with the use of PV cells, or water can be fed by gravity.

I also have ceramic filters, and of course, charcoal can be used in various stages of purification.

Of primary importance is access to water.

I would gladly lay aside the use of arms and settle matters by negotiation, but unless the whole will, the matter ends, and I take up my battle rifle, and thank God that He has put it within my grasp.

Audit Fort Knox!
