Knowing the way APUG discussions go, I can't wait until we start talking about the best mixture of heads, hearts and tails.....

I never said it would be cost effective at least for my first year. I just like contructing a thing like that. It's just fascinating how simple many devices are. I'm that boy that deconstructed his Christmas toys a week after he got them, LOL. I guess that's why alt. proc. seems like old home week even though its totally new to me.

I've made a continuous lighting light stand out of PVC pipe, some of those metal bowl reflector things with light sockets in the center (I cant remember what they're called) and some CF bulbs. I've also constructed some reflectors out of various materials. Although I only use those things when photographing still lifes and such, they're delightfully simple to make, easy to use, and (most importantly) they work.
If you can figure out how to make a still, go ahead. Post some pictures and instructions on how you did it. I'm actually kinda curious about it now :)
OK - you don't want to try and make a rectifying/fractionating still. But how about something like this:
GE Profile Reverse Osmosis Filtration System, Model PXRQ15F only $279.00/EA Each at Home Depot. Similar to the Millipore system that was mentioned above. It should work just fine.
Santaria rituals, hey, it might help!Quote:

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.)
A large stock pot sat on an electric hotplate; through the lid of the stockpot a 1/4 copper tube fed water in through a float-operated valve built out of carburetor parts. The "worm" was closely wound copper tubing inside the one-inch brass standpipe from a toilet. Well water went in and out of the brass pipe from bottom to top, so that the warmest water left where the steam was coming in. I don't recall what we used to seal the worm (condenser tube) to the brass pipe, but it was probably either brass washers or discs made out of flattened copper tubing, all soldered together.
This was it, basically. If memory serves, production was about a gallon per hour of not exceptionally good water. It turns out that unless a still is pretty well designed, a fair amount of water gets carried out in the form of droplets; for Mom's steam iron or making up developer, it was fine, but I wouldn't put this rig up against anything made by Barnstead or Corning.
A few details have been lost from memory, such as how we sealed the penetrations for water feed and steam removal to the lid of the pot. But if I were going to do it over again, a few minutes in the MSC, McMaster-Carr, or Grainger catalogs would locate things like bulkhead fittings and float valves. If your water is really hard, and you want a lot of water, first buy stock in your local energy supplier and then rig an overflow so that there is a constant wastage of water from the boiler, to carry off the concentrated salts. Even then, you will probably have to de-grunge the boiler fairly often, since the ever-present calcium and magnesium will make a scale that insulates the bottom and spoils heat transfer from the hotplate.
There. Now aren't you glad that you asked?
As long as this thread isn't dead yet, I'll apologize for my obscure post above. I expected that amongst the over-educated here, there would be some who understood what heads, hearts and tails were, and we would have an insider's laugh. Let me clear up the mystery
When you distill a fermented liquid, various fractions boil off in a sequence. If you have a good thermometer, you can watch the progression. The first ones, heads, are rather paint-thinner like, and are discarded. Then comes the good stuff, the hearts, followed by the tails. It's the distiller's art to know how much of the tails to include.
If you'd like to elliminate those spits of water droplets, you might try Raschig rings, or build what the moonshiners would call a 'doubler' or 'thumper' - run the discharge steam down a tube inside a sealed container (big Mason jar) partially filled with 'product' (distilled water, of course). The steam will condense and then reboil. Vent the container so that the reboiled steam passes through your worm, and what you collect will be much purer than the first boil-off.
