studies have shown that in the presence of fluoride, aluminum leaches out of cookware. Boiling fluoridated tap water in an aluminum pan leached almost 200 parts per million (ppm) of aluminum into the water in 10 minutes.

Leaching of up to 600 PPM occurred with prolonged boiling.

recyclers will pay you money for your aluminum pots and pans.

then you can use that money along with all the money you will
save on future medical bill to buy yourself a set of stainless
steel pots and pans.

if you are planning to build a water distiller for yourself
to provide yourself with safe drinking and cooking water then
you should research the possibility of using a stainless steel pressure cooker as your boiler vs an aluminum pressure cooker.

It shouldn't matter on the distiller whether you use Aluminium or stainless steel, as your interest is in the steam that boils off, and I doubt fluoride and Aluminium can become volatile and boil over. They are salts which are left behind when the water evaporates. They will build up and cause residues which will interfere with heating evenly, and should be removed periodically. But they don't boil over with water.

that's what I always thought myself , but I recently read that
toxins ( the article I read didn't specify which toxins ) were
carried in the water vapor inside a distiller , the toxins are
only removed when the vapors are further heated in the process
causing the water vapor to become a dry steam.

this further process of heating occurs in the tubes that lead from the boiler and in the condenser where the steam condenses
back into water.

my thoughts are less toxins (aluminum) forming on the walls of a distillers pipes / tubes equates to a cleaner distiller and cleaner distilled water.

While I realize that Paul is truly concerned about the problems of fluoride and aluminum in driking water I think he is much more concerned than is warranted. As far as fluoride is concerned the hazards are much lower than the benefits. The use of fluoride in drinking water has led to a vast improvement in dental health. This has been attested in study after study. It is not clear that there is a significant hazard, at the level maintained in city water systems.

I also sometime in the past year saw a report that many children are having dental health problems because they are drinking bottled water instead of city water. The city water is better for their health, unless the city has an extremely poor water system. Then the hazards are from other things than the fluoride.

As far as aluminum is concerned. I just checked Aluminum Toxicity at Medscape. There is a long article about aluminum toxicity. The overall thing that I came away with is that almost all aluminum toxicity cases occur in people with impaired renal capacity. Mostly it appears that they get the aluminum from various procedures involving injections. One of the main ones is dialysis with a media that includes aluminum. I think most sources of dialysis materials are aware of this now provide aluminum free materials. Orally ingested aluminum is normally rejected by the intestines. So concerns about aluminum in water are probably much overstated.

I just don't like the idea of drinking toxic waste
when I drink water.

I also don't like getting aluminum mixed in with the water when I boil water tainted with toxic fluoride on the stove
in a aluminum pot.

or when I make a pot of coffee or ice tea or cook some
grits or when I cook anything that contains water in a
can because canned foods almost always contain city
water that also has the toxic fluorine chemicals delivered
in the can.

I don't use aluminum pots.

to reduce my chances of toxin uptake , I drain the can
of all the water in it.

then I add distilled water to the pot to cook with.

the PH level of my distilled water is around 5.5 - 5.8
this is a acidic level.

city water has a PH level of around 7.0 neutral.

I add a small amount of baking soda to the distilled water
to bring the PH level of the water to around
7.0 which is neutral.

city water pipes aren't the cleanest things in the world
if you ever get a chance to look inside one , take a barf
bag with you , you should also get to smell it , for the
full effect.

heres a picture of what your homes city water supply
looks like when heated in your water heater.

what is all of that?



makes you wonder if washing dishes in hot water is still
a good idea...

here are the recommended daily intake levels of
vitamins and minerals.

I couldn't find aluminum.

http://www.lenntech.com/recommended-daily-intake.htm

I did find this.

Quote:
average aluminum intake for humans is 10 mg/day.


10 mg/l = 10 ppm

https://www.ncbi.nlm.nih.gov/pubmed/12089908

Quote:
studies have shown that in the presence of fluoride, aluminum leaches out of cookware. Boiling fluoridated tap water in an aluminum pan leached almost 200 parts per million (ppm) of aluminum into the water in 10 minutes.

Leaching of up to 600 PPM occurred with prolonged boiling.


200 - 600 ppm for 1 pot of coffee in the morning
would equal 20 - 60 times the daily average intake
of aluminum.

"Average aluminum intake for humans is 10 mg." Is that the amount absorbed or the amount ingested? The link I gave above says that very little aluminum is absorbed from the digestive system, so that would make a big difference in the actual amount that we capture in our bodies.

As I said it seems that most of the people who are suffering from aluminum toxicity are those who got it injected in some way during medical procedures. Actually ingesting the stuff with our food and drink doesn't seem to be much of a problem.

One thing I kind of question about the information in the link is that there is no dietary requirement for aluminum. That is, in my opinion, possibly a bit quick. They keep finding new things that we need in our diet, but the need is so small that we don't notice it. Aluminum may be in that category. And that is simply my opinion, there is absolutely no data about it one way or the other, so don't pay a lot of attention to this paragraph.

10 mg/l a day is the average intake from all normal sources.

its not the amount absorbed.

Im wondering if aluminum can be absorbed subliminally.

If 10 mg/day is not the amount absorbed into the body then it depends on just how much is absorbed on how much is a problem. And as the link indicated the absorption from the intestines is very low.

the absorption rate per day is important , but how much
stays in the body , how fast the body can rid itself of
the aluminum is also important.

suppose the amount of absorbed aluminum per day is
only .001 mg per day when the intake is 10 mg/l per day.

by increasing the intake of aluminum from 10mg/l per day
to 200mg/l per day this would equate to an absorption of
.020 mg per day.

and if the body can only rid itself of .010 mg per day then
an accumulation of aluminum will occur in the body.

Paul, this isn't really a reply to your post, for that I suggest you look at the link I gave. This is just a question. Up above you suggested using a stainless steel pressure cooker to make a still. All at once I realized that I don't know why you would need to use a pressure cooker at all. I wouldn't think you would need high pressure in a still. After all the outlet is open to the atmosphere, or at least I assume it is. Unless you are emptying it into a pressurized system. So, why do you need a pressure cooker?

because they have a lid that will seal.

and they have 2 holes that can be modified for the tubes
that lead to the pressure cooker as a feed tube and as
a steam tube going to the condenser.

but your right I dont need a pressure cooker , it just seems
the right choice because the holes are already there / drilled.

stainless steel is really hard to drill through.

If you think it would be hard to drill you could use something else that already had good sized hole in it and use a cork to stop the hole. A cork would be much easier to drill. If you didn't need a lot of capacity you could even use a tea kettle. I expect there are other things that could be used.

I have seen a still that was set up with glass laboratory vessels and tubing. That might get a bit more expensive. I'd have to go wander around the hardware store and see what I could find to make a still out of.

The hardest thing might turn out to be coiling copper tubing into a good tight spiral without collapsing it.

I have already bought a 50 ft roll of 3/8 th inch copper
tubing , but Im wondering if stainless steel tubing would be better.

I have already built a distiller out of a aluminum pressure
cooker and the copper tube that I used for the condenser was
not long enough (11 ft) to allow time to fully condensate the steam
so , that's why I bought the 50 ft roll. LOL

ie... mostly steam came out of the tube...

my next attempt will be with a stainless steel pressure cooker.

I have looked at a stainless steel tea pot , but I decided
it would require to much modification.

I also have plans to build a distiller that does not have any type of container that holds any large volume of water.

it will be a pressure connection to the city water supply and
will drip water into a coiled stainless steel tube !!! that is heated using electricity or gas.

I currently buy apx 8 gallons of distilled water a week.

I expect to save a good bit of money and feel better about
what I drink.

I don't think I would want to use any cork as cork would
allow bacteria to become a problem.

I have seen the glass distillers that are for lab use
and they are expensive and they just look fragile , I want something that will be sturdy but I also want it to be effective.

you can coil copper tubing by filling it with sand
before you coil it , but you still have to be careful
about collapsing it.

I expect that there are about a million ways to build a still. I recall one that was on sale some time back. It was a pan with an upside down cone over it. The steam from the boiling water condensed on the inside of the cone and was caught by a pan under the boiler. I don't think it was particularly efficient and had a pretty low output.
