  1. Any chance we could see a detailed diagram with material list? This is a nice video but it lacks the details people would need to safely build these. You use the wrong materials and you could be drinking heavily chemicalized water (aka stuff that can evaporate with or even BEFORE water will)

  2. If you just want a fun little thing, you can take a bowl, a cup, a small weight (rock), and a piece of syran wrap, put 1-2 inches of water in the bowl, then put the cup in the water so that the cup does not fill with water from the bowl (right side up), put the syran wrap across the top, and the weight directly over the cup. Once the cup fills, you have a cup of warm, but drinkable, water…

  3. 2 square Meters is a huge panel .I guess that would have to ideally be mounted on a roof or something out of the way and not of glass .

  4. use it for couple years and then you will get lots of healthy problem because of calcium, magnesium, iron and etc deficiency( especially if you dont have a good Feeding regime)

  5. Distilled water takes away the INorganic (stones) minerals from your body while leaving all the organic minerals unaffected.
    You are supposed to get your minerals from alkaline FOOD which provides them in the ORGANIC state —the ONLY ONE usable by human physiology—, and drink distilled water to get rid of inorganic minerals (stones).
    Look it up. Invistigating the matter thoroughly before expressing yourself thru “bro-science” would have been a wise choice.

  6. I tried it: placed a glass bowl inside a food grade plastic bucket, covered it with saran wrap – did the rock thing…placed it in a very sunny area (west exposure). After 3 days I got one cup of distilled water, and it tasted really BITTER! I was disappointed and stopped the experiment..What could be the reason?

  7. Plastic is not good for you, but it is better than drinking the fluoridated water that is laced with drugs that comes out of your tap at home. Glass is the way to go if you can.

  8. Not sure I would use wood since they are chemically treated to keep it from rotting and bug & fire proofing unless you cut your own tree down, I would stay away from it.

  9. not that I know of…I just took 2 seperate systems and combined…you could go to "ABOUTSOLARCELLS.COMXA.COM" and get ideas…thats where all mine come from.

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

  11. 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.

  12. 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.

  13. Good advice. A still cleans itself but it takes time…sometime. Unless you have some pretty horrible stuff the taste test works well.

  14. YouTube is amazing and has good ideas. Go to solaqua.com for plans and DIY

  15. solaqua.com or think about a bathtub with a piece of glass on top. Don't make your bathtub out of anyting that you wouldn't want in our water.

  16. My guess would be the plastic bucket and the saran wrap. Don't put anything into your system that you don't want to drink. Try the experiment again and see if it is better the second time around

  17. Great question. Plastics can be a problem. Always check the temperature and outgassing problems with the plastic you are using. Polycarbonate has shown itself to be the most friendly material. If you can taste it, then it is a problem

  18. I'm with you! Any dillution effect from distilled water is minimal compared to what you take in from food. Proven over and over

  19. are there instructions on the site? not clear how water gets into the unit.

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

  21. That is not what I'm saying at all, lol. I am informing you that minerals (vitamins and nutrients) also exist in drinking water. I'll tell you something else: If you drink pure water, with NOTHING else than H2O in it, it's actually toxic for the human body. 😉

    I'm not saying we should only drink water at all. You're jumping to conclusions.

  22. in reply to Gunzshow 55312
    PLEASE tell me you're joking about this guy not being an American. New Mexico is the big space west of Texas and east of Arizona. It's the 47th State (January 1912), and has the oldest continuously-ocupied capital in the United States (Santa Fe). We got our first European settlers (Spanish, under Don Juan de Onate) in 1598, well before most all the rest of the area that became the USA. And, we were the first place in the world to be nuked (Trinity Site, near Alamogordo, 1945).  

  23. Hi, nice video! I'm trying to design one of these on a large scale as a permanent primary water source for a small village of 27 people. Can you just clarify how the inside of the 'tool box' looks? On that angle, how does the water evaporate and not fall back into the original water stock? Is there a wall separating the two water bodies? cheers  

  24. 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.

  25. Thanks for the video I can't build that can u tell where I could buy a good filter. Many people spend thousands on cloths n material things and forget their health we need more of u in this world I'm Jamaican and want a better safe water to brink please advice where I can buy a good filter

  26. is it safe to drink after being distilled or does it need another process?

  27. Sure need to find some people who already know how to do this to show me, hands on; I can't figure out anything from this video, except a general idea that it is possible.  But, I think it is massively important to know — there don't seem to be any clean water sources left anywhere in the Western world anymore.  Pollution everywhere.

  28. What's the point if you don't give some details on the innards or the construction?

  29. One concern I have with this system: How do you prevent bacterial/fungal growth? After a few days I would think you might want to boil any water that comes out of there.

  30. 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 ?

  31. What kind of chemicals are in the poly carbonate plastics though .. We all know no plastics are full of carcinogens .

  32. Not sure about the polycarbonate cover.  If i remember correctly,  plastics break down in direct sunlight. I think glass is the best choice.

  33. cool device, you need a squeegee mounted on a track like a drawer inside the box to
    push the droplets off faster

  34. want to know if it satisfies the mineral requirements needed for water to become 'drinking' water.  What i would like to know is how to make it a more permanent solution for coastal communities who are suffering from saline intrusion in their drinking water.  This would help.  My initial hunch is that As IS it can be prescribed to communities during disasters as a temporary solution to their drinking water crisis.

  35. 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.

  36. Great video. Can you please tell me how to actually build the one on the left with the glass. I have all the materials, I just need to know how. Thanks

  37. very inefficient, you probably need to do something based on Fresnel Lens.

  38. OK, better than nothing. But removing weight chemicals as in heavy oil parts are a big problem. Isnt it What else is heavywight? Heavy metals? Large molecule stuff? In another video a guy did put food colorant in it and it was in the destilled water too! This is not very promissing and let me not feel safe.

  39. yes, I know it sounds gross, I'm not trying to be funny, but in a survival situation, could you distill urine? I would think you could..

  40. Too much plastic being used. You're making clean water, but running it through plastic.

  41. 5 Gal Home Brew Distiller,Stainless Moonshine Alcohol Still/Spirits Boiler.If you are interested,you can view it


  42. 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

  43. Using plexiglass defeats the purpose as does the chemical leeching plastic storage container you are using to collect the end product. No plastics and no aluminium or zinc products should be used for this.

  44. Gravity induced vacuum distillation will do what you want faster and if you add a steam turbine you can make electricity. Water boils in a vacuum at room temperatures 75 degrees F . You can make a cheap vacuum system capable of a hard vacuum of 30 inches of mercury with piping in a vertical direction 12 meters inside an open topped pipe length 10 meters. The inside pipe has valves at the top and bottom, the inside pipe is filled with seawater to the top then close top valve and open the bottom valve gravity will pull the water down leaving 2 meters worth of hard vacuum as it fills up the 10-meter outer pipe.
    Now how do we get the fresh water out? We set up another vacuum pipe connect them with a condenser coil cooled with sea water and shaded from the sun taking the vaporized water from Vac A to Vac B where being a lower temp condenses to be removed at the bottom valve of Vac B. To make the system flow continuously add a spray nozzle to the top of Vac A spraying in seawater warmed by the sun after cooling the condenser coil of Vac B the spray increase the surface area making instant steam in Vac A creating fresh water as fast as in can condense in Vac B.

  45. Lets build massive industrial sized distillers on the Sahara desert, and start turing sea water into a massive agricultural zone. Lower the sea level, and combat climate change.

  46. 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.

  47. This is a great guideline gives you all the information you need regarding building a home solar electrical power system [Awesome Plan Here >>>https://t.co/z2HakYxvSR ]. In plain language it tells you what you need to know. And how to put it together with common sense applications.

  48. you should only use stainless steel and glass. plastic has deadly bpa and leaches into water. repeat no plastic ever or you will die

  49. Thank a lot for the information, I have a question, the water got is destilated or it have enough minerals to be drunk?

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

  51. 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.

  52. Hi, does any have construction idea of this project? i.e. how to construct this correctly

  53. this is one reason why the government is actively spraying the skies to block out the sun.

  54. Can't believe anyone would use Plexiglas or any plastic material as a condensation surface for a still.
    You'd think everyone would have known by now, that the sun causes molecules to move from the plastic into the water. If neighborhood dentists know about it, this fact should have reached just about everywhere?

    One of the reasons to avoid water that comes in plastic bottles… Solar stills should be made from stainless, glass and as little else as possible.

  55. Congratulations ????
    God bless you for it!!!
    Please I have a question:

    Using that process Can I make dirty water become clean water to drink?
    Please sorry for my bad english and thank you very much professor

  56. 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 hear intermittently spurting water on the glass helps.

  57. I remembered that pre urine water drinking in waterworld so i was wondering how to actually avoid that.
