Since we all understand that you are not into this for economy (the energy cost per gallon for a simple still is pretty high, and reverse osmosis wastes a lot of water) I can in good conscience tell how the one we built back in the '60s worked. (This was North Alabama on TVA electricity, really cheap at least back then, and we had our own well so the condenser water was not a big issue.)
There. Now aren't you glad that you asked?
The science is still the same, but TVA is no longer cheap.
