[@tomcornwell4688]

+IClausius For those looking for plans, here are a couple. The first, I remember from when I subscribed in 1974: www.motherearthnews.com/renewable-energy/solar-still-zmaz74sozraw.aspx?PageId=2 www.motherearthnews.com/diy/home/how-to-make-a-solar-still-ze0z1209zsch.aspx For those concerned about the lack of minerals (not sure how you are monitoring for the presence and amount in your current drinking water, but...), consider adding a colloidal mineral to your final distilled product, if you feel that you are missing out. We use a product called Concentrace. Finally, it is my understanding that certain solvents in the water will boil off before the water due to a lower boiling temp. For this reason a cheap carbon filtration device should be added to the out-going line, prior to hitting the collection bottle. Obviously, this filter should be changed frequently.

I have noted up to the first 100ml may contain hydrocarbons from gasoline, or other contaminates which are heavier than water and come out first when condensed. Throw out the first 100 ml and then you should be good for that load of water you added to clean up to drink

[@AdrepKeith]

To the good fortune poster who said regular water has minerals that the body needs, thus those minerals are "food"......... I disagree!!! Number one our bodies get all the minerals we need from the food we eat (that is if we eat properly). Second there are scholars who say when we drink regular water with all those minerals in it, our kidneys have to work harder to filter junk that could cause health problems like calcium buildups in the arteries, or kidney stones etc. etc. Again there are those that believe drinking distilled water is much more natural than drinking water filtered through rocks and sand. Their thinking is rainwater is actually distilled water to begin with, and it's the water plants thrive on so it should be good for us humans as well. I subscibe to that theory.

[@kazadthebad9995]

I tend to agree with you but think even though rainwater has been naturally distilled it has to fall back through our polluted skies to us and will inadvertently gather whatever that is.

A system like this was built by Americans in South America ( Chile?)I the 1900s, It provided hundreds of liters a day for the local residents , I can't understand why these stills aren't built in every poor country.

[@didanhtennis]

Good question, I was wondering about that too. My guess is yes. But I haven't tested yet. Have you got any answer?

[@nerapsnart]

A barrel isn't necessarily the best tool for the job, but it will work in a pinch. The design shown in the video is more productive for distilling water because the area for condensation is greater and at an angle to naturally create more coverage for evaporated water to cling to for collection. The water is closer to the 1st stage of collection and depending on the area and size of the glass you use, it might be a lot of water you could be collecting.

[@rdeepika3254]

May I know where this process is implementing?

Once the cup fills, you have a cup of warm, but drinkable, water...

[@The0ldg0at]

Those are single chamber solar still. Do you have two chambers (evaporation chamber + condensation chamber) solar still models?

[@kosherpork3034]

The idea is simple, but you don't find any company making it. Unless it's air tight, bacteria might get into the condensed water. A simpler approach might be to have a larger glass jar containing a smaller glass jar, using the large one as the condensation collector. It must be airtight, and using an upside down glass to prop up the smaller jar to the view of the sun, and bury the condensation collection part under the shade.

[@fajile5109]

Even if it gets bacteria without nutrients it wont have any growth. The only one i cant think is botulism but the requires rusty metal. You could turn pee into water using this. Perhaps more dangerous would be a fungi. As it could just live in the tank and spore into the distilled water. Besides this water is mostly pure its good for cooking but id probably run it through a second solar distiller thats only running once distilled water so it should stay extremely clean.

[@srofficial06]

Ty professor for sharing this . Would it also be true that if the water bottle you were using were kept in a significantly cooler environment " out of the sun" so to speak that the difference in tempurature would cause the water to condense and or collect into the bottle or bottles that much more easier ?

hah, you beat me to it.

[@Pharesm]

@ You're missing a relevant detail: Glass is easier to come by and cheaper than Plexiglas. Generally, Plexiglas is used either out of laziness by the crafter or, because they need to bend it and are only doing a one-off. Maybe to reduce risk of shattering. but neither of those is an issue / requirement for a still. So I'll call their use of Plexiglas gratuitous... You can actually make pretty good stills with just some bamboo, sand or even mud. Enough examples on YT. Watch some of those vids, those guys kick ass in helping themselves. Its not like everybody outside the first world is brain-dead and incapable... its more like western manipulations cause a constant and intended state of chaos and poverty they can't overcome.

Yes it can. You can make a solar still by digging a hole in the ground, lining the hole with plant water, waste water, etc., And capturing it with a tarp. You need a rock at the center of the tarp, and a cup and tube to drink from as water drips below the rock. You'll need 6 or more of these per person.

[@WTF_BBQ]

Actually, direct sunlight kills bacteria and virus. I don't know about fungi, but most fungi likes to grow in dark moist areas.

Also bacteria need to feed off something. Distilled water is not suitable for bacteria to grow in because it provides no food for the bacteria.

so boiling is not necessary for pure water or it does boil technically?

Boiling the water only kills living threats, the water will still be contaminated with chemicals, pharmaceuticals, heavy metals, etc Also I think a solar distiller does technically boil the water because it turns it into a gas.

Thanks for sharing! Calcium and lime kill evaporative coolers... I'm in Las Cruces, interested in installing a distillation unit to feed my 3 ton evaporative cooler. Assuming 15 gals per hour, that's 360 gals per day, requiring 720 square meters of glass (a 27m square). That's a 88ft square or 7750 sqft. Not very reasonable for a 1400 sqft home, as it would take up the whole plot of land. What can be done to make the distillation process more efficient?

I have been watching videos about distilling water for some time. The points I have heard are that most minerals that are removed from the body through urination while drinking distilled water are either excess minerals or non organic forms of these minerals your body does not utilize anyway. That a 1/4 teaspoon Himalayan salt per gallon of water will add mineral nutrients you need.

[@Milosz_Ostrow]

gconol Water bottles used by drinking water services such as Alhambra and Arrowhead are made of polycarbonate, and so are bubble canopies on jet fighters. The stuff is quite stable in sunlight.

[@WTF_BBQ]

***** On a macroscopic level? Yes, they are stable. But in a microscopic level, they do break down and it dissolves into the water. The plastics that are floating in the ocean have been degrading because of sun exposure. They've become so tiny now that smaller fish are eating them. It's one thing to drink water with a little bit of plastic dissolved in it during an emergency, but on a daily basis that's going to kill you.

[@Milosz_Ostrow]

gconol Considering that we've been exposed to plastics for over three generations and people don't have three eyes or horns growing out of their foreheads yet, I'd say the risk is very, very low. I'm not worried.

[@1971SuperLead]

Always throw away the first ounce of water from each batch as some chemicals evaporate and condense like water. Don't drink the last ounce either. The difference being that chemicals evaporate at different temps than water and so they make their appearance at the beginning and end of a distillation. You could also just throw away the first ounce and stop the distillation process before all the water is gone.

[@falsehoodbasher7240]

Why don’t you just don’t condense for 5 min then start condensing after The 5 minutes is up. In addition to stop evaporating before water empties,

[@melreslor2114]

One square meter distiller can produce maybe 1 gallon (4 litres) on a summer day with full sun. Over one year, figure 2 litres average per day with no down time, winter much less than summer, for a distiller this size. The presenter Kenny Stevens said a 2-sq. meter distiller can produce the water needs for a family of 4. In reality this is not accurate. It would in ideal conditions output 2 gallons of distilled water on a summer day, just enough for drinking, leaving nothing for cooking or a sponge bath.

[@jasonnyc2006]

Does this work for chemically dirty water?

[@grayhand9676]

Most organic chemicals including gasoline have a higher evaporation rate than water. If there's chemical contaminants they usually discard the first cup to liter of water. If there's still some in the water just run the same water back through the system and repeat the process discarding the first water produced. The bigger problem tends to be with water with strong odors. Those can be tough to remove but lightweight chemicals are less of a problem. He didn't show it but usually you do a prefilter with something like an old piece of cotton cloth like an old t-shirt. You want as much of the solids and organic matter as possible removed from the water. Sea water can be one of the easiest and the left over brine can be cooked down into salt. If you want to improve efficiency make sure there's good airflow across the surface of the glass. The temperature difference between the inside and outside of the glass is causing the condensation. You can even put a wet towel across the top. The water evaporating will cool the glass increasing output.

[@jasonnyc2006]

Cary Howe Thank you so much for the detailed breakdown. I have been doing more research on this & what you say is confirmation of it :).

[@grayhand9676]

Just glad it helped clarify the situation. Some of the simplest systems can be the most confusing especially when you can't look over it for yourself. I saw a video on a really nice rocket stove and heated bench set up and based on the video I couldn't tell where the outlet pipe connected to the reburn chamber. After watching it three or four times I finally caught a glimpse of it the corner of a shot. Details matter. The first time I saw this system of biochar burners I did a little head scratching until realized the weight of the drum and wood was creating a seal and the back pressure kept the oxygen from entering. Good luck with everything and glad I could help.

[@GEAUXFRUGAL]

Could you speed up the process and increase the output using evaporated tubes? Doing so would also negate the need for a see thru membrane? All that matters is the collector be food grade material that will not break down with the levels of UV and heat it should experience? My logic behind increased production is some days you will have clouds this could reduce your production so you want to cooking with grease so to speak? I have purchased smaller evaporated tube for less ~$10 each their volume was just 20 oz but in under 45 min that 20 oz was boiling without a collector add a collector 15 min boil.

You can and the water will be fine (I actually a science project that proved this!) .However, if this is your sole water source, your urine becomes thick and you get very little water out of doing this.

[@shaunfogarty3020]

well, you can drink urine, so sure

[@HoboInASuit4Tune]

Not true. Water is full of all sorts of minerals, and thus water is a source of 'food' as well, in a way.

I took great plans from Avasva . It help me a lot with my own solars.

[@McStrugs]

yes

[@shannonnunn]

make those for california

[@kennystevens3448]

You're right. Sorry. Go to solaqua.com for some really good ideas. You can buy the completed unit or get plans. Think about about a bathtub with a piece of glass on top of it. Just don't make the bathtub out of anything that you wouldn't want in your water. Bathtub plus inclined piece of glass = solar still. Write me back if this doesn't make sense.

Will this filter out cyanides in mining water too?

[@momocitoes]

when water evaporates i, it will leave everything behind. its a really basic day one science stuff right there.

Why in the world would this video show up when you search for "large scale solar water still" first of all there is nothing large about it. It has a size limit, and you are seeing it. It can only be small, it produces very little water, and cost to make enough water to provide for all of a households water needs is out of the question, as well as maintaining the multiple stills. It is old tech, and highly limited in use and size. The answer is out there, but this version is not the answer.

the principle of solar distilling remains the same. with a decent design it works, simple , elegant.

"Here are two magic boxes that purify water with sunlight; but, I won't show you how they're built, how bad water goes into them, nor how the bad stuff is removed from them." Fail.
