DIY Salt-Water Survival Bottle (Compact Desalination Kit)

Thanks to Dollar Shave Club for sponsoring. Go to → www.dollarshaveclub.com/night... to get your first Starter Set for $5. After that, the restock box ships regular-sized products at regular price.
In this video I show how to make a simple distillation kit from a water bottle that can be used to make fresh water from ocean water. Any steel container could work for this project. I almost used a small stainless steel food container, but decided a water bottle was a more practical object to carry.

I would recommend using only stainless steel parts. Copper in contact with distilled water oxidizes quickly and this oxidation contaminates the water. Another tip is to leave dolomite tablets in contact with water for a few minutes to raise the ph and recover magnesium and calcium. We also have to be careful with excess boron in desalinated sea water, sometimes the steam pressure drags the boron. I prefer to use brackish water.

[@katatoth7551]

If you use an open fire to cook while camping; you can use bar soap and splash of water to coat the outside of the cookware in a thin layer. This will allow the soot from the fire to be clean off very easily when finished.

[@DR-bp1yu]

Great tip, thank you. Another option would be to wrap the bottle in tinfoil or aluminum foil. A soda can can also be sn effective sleeve. The steel in the bottle would not stay pristine though, as the heat will induce a color change. But it will not be covered in sooth, which is much worse. Once the bottle cools enough to touch, you can use a mix of wood ash from your fire and a bit of your clean water to make a nice cleaning paste, it will scrub the bottle nicely without scratching it.

[@chloedemeter5473]

Thin layer of mud works ok too. Just enough to coat it, too thick and it'll quickly crack and fall off in big pieces when it dries.

It is important to keep the copper clean as it will oxidize along with picking up a black substance that is more dangerous. The best way to clean is use citric acid solution and then rinse well. Some will rinse with a 50/50 vinegar/water solution followed with straight water.

[@rsnell22]

Hmm. Like the oil cooler on an old 19DA where the water chemistry wasn't kept up with. I, too, would use stainless.

[@ecr1023]

Copper is used in Espresso machine boilers. Just use a standard descaler or vinegar solution.

[@whipivy]

Something to keep in mind with this, stainless steel when heated to a certain point creates chromium carbide. This is bad, when the chromium has been reduced to a certain point stainless steel begins to corrode. You'll see it when stainless steel begins to show purple bands in it, that means it's too hot to maintain it's resistance to corrosion.

[@buffplums]

Wow that’s good advice …. Wonder if there is an alternative way to make something like this ? I don’t suppose Aluminium could be used, apart from the risk of melting it but would there be a contamination risk from that also? Maybe that would be ok as we cook with aluminium pans.

[@Axel_Andersen]

@@buffplums We also cook with stainless all the time year after year. Yes this chromium corrosion is a thing but not in this contex and temperature. As long as there is water inside the bottle the temp can hardly rise above 100°C because this is not a pressure vessel. And because it is not pressure vessel corrosion is not a thing, it would only cause it to leak, not likely to cause any problems.

[@simplekindofman6265]

Would tin be better for water distillation I’d like to make one for camping long term So I don’t have to carry water

[@megastick9324]

At cooking temperatures it’s not an issue. The hexavalent becomes an issue when heated to melting, such as welding, and then it depends on the process. Stick welding releases hex. Chrome, however, tig welding keeps any release within acceptable safety margins. This from a professional welder. We never heard a thing about hex. Chrome until just around 15ish years ago. Now, when stick welding we need respirators, not so with tig. After many years of never having been told about it and God knows how much intake.

Do you happen to know if the copper releases any harmful substances as it may on alcohol distillation? I have read about copper poisoning when boiling on copper kettles, but what about steam passing through it?

[@SH1974]

A connection tube about 8-10" long or so to connect the bottle and the cooling spiral could give 2 advantages: - more distance between the cooling spiral and the heat source under the bottle - the connection tube could have a knee that brings the winding of the coil in horizontal position. Open the coil (separate the windings about 1/2 inch to each other) also helps the condensing water rinse out the tube. Tat helps keeping pressure in the boiler constant, so You'll have less "boil over".

My thoughts for improvements while I was watching it were: 1) it would be good to be able to adjust the height of the bottle to control the heat; this could be just a knot in the rope, or other device, and 2) you could stuff the damp cloth inside the coil, instead of draping it overtop. Better yet, have a vessel, like your food mug, just the right size so you can immerse the coil in it.

All I would do is make the distance between the coil and flask greater to maintain the differential or shield the coil from the heat source with anything reflective or something insulating and not too flammable like bark. I doubt, however, this would improve function by much. I'm always happy to see your videos pop up, thanks.

[@Mr3344555]

There's no purpose, if the whole concept is to be compact, your design change is going against it. It also a non functional Destin change, so no need.

[@jimphubar]

@@Mr3344555 If you would kindly reread my comment you'll find we almost agree. The 'purpose' is to desalinate water by way of distillation using a compact unit. Distillation works by creating a heat differential between the evaporator and the condenser. Therefore increasing the temperature difference will, necessarily, improve function. The inverse-square law means that a small distance further away will have a seemingly great effect on said differential. Adding an extra few centimetres after the condensing coil will hardly make this a bulky item. Equally, it would be little effort to shield the coil from radiant heat. The bit I think you missed was.."I doubt, however, this would improve function by much." J.

Heat both piece up slowly so they reach the melting temp at the same time, and then apply a little more heat until the solder "wets" and wicks up the parts, remove heat and let the joint cool on its own.

1. Try a bottle with a lid that goes all the way to the outside of the bottle, and a liner. Can remove liner and use it to catch distilled water. Place the liner back in the bottle for storing freshwater so you don't have a salty taste. 2. If enough space, can place coil between this liner and metal bottle. 3. Since the temp should not exceed boiling temp, can use plastic tubing instead of copper. 4. Use screw fitting rather than soldering - soldering can break down at high temps. 5. Use the tubing for the bend rather than a fitting to drop weight. 6. When buying fitting, also buy an endcap so it won't spill water when using for water storage and not distilling. Leave fitting on tube rather than relying on compression for easier change out. 7. Installing copper wool in the tubing increases condensation (more contact area for water droplets). 8. Burn inside of bottle thoroughly to remove any lining. 9. If hard to remove gasket, buy 2 lids - 1 for distilling without gasket, 1 with gasket for water storage.

[@1SCme]

@Tai Chi Tube They're already using copper tubing. It's fine - the amount of copper you would need to ingest to be toxic is substantial (above 10 mg a day) - to put into perspective, this is about the same as 1 inch length of 1/4" copper tubing in a month - you wouldn't lose even close to this much after continuous use for years. You would want to check the plastic type, but it is commonly used in food processing at home and at manufacturing plants. If you're searching desperately for a problem, you would note the low thermal transfer of most plastics... but concern with copper is a desperate reach.

You should start a daily vlog channel. Your bird is so interactive with you. Great job raising it. So interesting.

[@wes326]

Thanks for sharing. I saw another video where they took a pot of water about 1/3 full, put a bowl in the middle, then set a curved pot lid on top except upside down. The boiling water condensed on the lid and dripped into the bowl. Probably the simplest system I have seen.

[@williambrandondavis6897]

that's the old 90's method for iso hash. lol

[@bpwarren2930]

The information in your videos is very resourceful, too.

[@HassanDibani]

Planning a 2021 cycle trip in the Moroccan sahara, It's a good idea to take this with me as a backup. thanks for sharing.

[@harrisons6685]

So many KZbin channels start out really well, then relatively quickly sell out their quality in exchange for money or popularity. Not so with yours. I have been subscribed to you for several years now, and every video you make is just as good as the one before it. Great job man! Thank you for your constant originality and consistency. Keep it up 👍👍👍

[@papchclav3315]

Well Sir, ur a great teacher. Lots of details.

[@vieuxacadian9455]

Great design . Easy way to thwart all the little nasty things in sweet water as well .

[@EgoBruiser]

lol cute conieur. glad you added that cooling bowl, watching the steam just poor out was driving me crazy, lol. i have built a few water distillation units in the past.

[@adamhutchinson4148]

This is an AMAZING idea and I will be trying this out myself when I get the chance! Keep the good ideas rolling!

[@rsnell22]

Dad was a desalinator guy on the USS Altamaha in WWII. And I ended up working with various steam and refrigeration systems.

[@johnharper9829]

Thank you. Going to get some parts and try this

[@CC-qg8wu]

I recommend that you reroute your copper coil outlet (since it's flexible enough) to be dipped at the bottom of the beaker to avoid lost steam and efficiency. Great video.

[@DingleFlop]

[@LDR33Pyrodyne]

A short length of silicon tubing thrown inside would do, wouldn't it? Then you wouldn't have to bend the copper back and forth

[@meejmuas8686]

He could just extend the copper tubing and have it bend at an arch to a point where it can touch the beaker at the bottom

[@kieranwalker6072]

Bonus feature: you could froth up a nice latte with that steam nozzle 😂

[@SnahLhug]

This is udder nonsense! But in all seriousness, a countryside survival latte with freshly milked udder squirt is a nice touch to a good, long hike.

[@XantherBlaze]

@@SnahLhug No, a funny cow is udder nonsense...

[@uunz4435]

I’m totally gonna try this by the ocean. Sounds fun

[@drakirger4297]

Im very happy that you also spoke about the fackt that water can get to pure and how to solve it

[@suivzmoi]

successfully used a bird to make me watch a whole ad

[@realxboxnoob3348]

Right

[@heinzkitzvelvet]

It's genius, is what it is. I *HATE* ads, with extreme prejudice! It's the reason I use the KZbin Vanced App (all pre-video ads are blocked) and don't own a television. But this was lovely, I have to admit.

[@CBEnoddyy]

Only thing he sold me was a bird, there now on the extinction watch list :)

[@brucewayne-ej3cx]

That bird has jedi light saber skills. You should edit footage with the beam and sound effects.

[@carrott1168]

She actually reads our comments

[@darknightx33x81]

Great video as always. Well explained and simplistic design for ease of making. A few recommendation for improving this project is to find an alternative to the small rubber stopper, as this will most likely be easily lost due to its small size and time it takes for distillation/ long time being a loose piece. If possible i would suggest something like a simple valve attached to the elbow and before the copper line fitting. secondly having a parts list either in the video description or shown in the video will help people recreate it as they wont need to search through the whole video for where you mention the piping size or type of vessel used. lastly a small safety tip for distilling water: if the water source is contaminated with chemicals or heavy metals (you may not know in a survival situation), it is good practice to allow the still run for a potentially a few minutes before collecting water to allow volatile chemicals to escape and just dump the residual water as it would still contain the heavy metals. Yes there is the potential of not taking in enough vitamins and minerals if you are drinking only distilled water but I personally don't know the extend of how dangerous it is so I will suggest do your own research/ personal decision. An idea for another project close to this is making a portable small sand filter.

[@abbycasanova1380]

Wow! Great video! A must survival gadget for all!

[@mixz9929]

You the man bro I'm glad I found your channel

[@ServitorSkull]

Thanks for showing your practice stuff. Great video!

[@Nighthawkinlight]

Check out the new Community Video Response playlist on my channel page! I'm trying to recreate the video response feature from the early days of KZbin. Since video responses have been missing from the site it has felt a lot less like a community and more like channels are islands off by themselves. I made many friends on KZbin years ago by filming responses to their videos and vice versa, so lets try to make that happen again. If you have made any of my projects film a quick video of them and send me a link to: [e-mail]. Looking forward to seeing your videos and featuring them in the playlist!

[@MrJust2times]

You need to find a solution for the cooling down process. Making the way longer ? What i would love too see how you get the Coper spiral into another bigger diameter spiral. In the bigger spiral you could pure Water to cool it down. Do you get what i mean :D 2nd langauge and stuff :P Greetings from Germany.

[@friendlydog82]

For your survival skill and that parrot entertainment, you deserve a like for sure!

[@hharrison-parker1606]

Brilliant! And I love that little bird

[@erickinney7482]

Ill remember this, The day might never come that I need it but now if it does come I got somthing ill remember,

[@felixcat9318]

What an interesting, informative and helpful video tutorial this is, with excellent narration and video presentation. This inexpensive construction will certainly come in useful if one only has salt water at hand, and it earns its place in a kit, pack, vehicle or vessel because it works! In short, this is literally a potential life saving device! I look forward to constructing one and to see how it compares to my Katadyn Survivor 06-LL Desalinator, which I keep with a Katadyn Pocket Water Filter to give me potable water Irrespective of the supply. The narrator's voice is excellent in this tutorial, clear, easy to comprehend and with a natural flow. Subscribed.

[@ThrobbingChomboni]

Thank you! I can't wait to try and make my own!

[@t.c.b4722]

So this could also be used to clean dirty fresh water as well. That's so cool.

[@williamwestrope3001]

This is a very good improvised distillation rig. The product is pure water from whatever quality water is being processed. It could be used on contaminated fresh water or (ewww!) urine. The product would still be wholesome distilled water. I wouldn't add any of the contaminants back in except with sea water though.

[@reichrunner1]

You still have to be careful with contaminated water though, as any volatile organic compounds would evaporate right along with the water and get condensed back into your "clean" water. You could fix this with multiple steps of recondencing at different temperatures, but this isn't really going to be practical for you to carry on a hike.

[@highonsmog]

That bird made me subscribe. Now I want to see a 1 hour long ASMR type video just showing the bird and listening to it.

[@eadghe]

You, sir, are a life saver! Thanks for sharing your knowledge basically for free! Cheers!

[@diywatch5776]

Good video

[@albertknight1971]

I put my 3 large Granite cobbles on the woodburner, stick them under the bed sometimes. They work excellent as emergency pant and sock dryers. Using my own candles for pot heaters. Just watched a genius at work. THE HOMEMADE motorcycle with a car engine.

[@richarddeleon3558]

Love it dude,!!! You go into details without going into boring details,,I'm into survivor stuff, this is good material.

[@1973Saved]

Just remember, there is not a thing wrong with drinking 'straight' distilled water, I've been drinking it exclusively for about 30 years, I am very healthy & my Primary Care Physician says that my bones are "well mineralized". If you don't believe me I suggest you do some research online & find out.

[@joeydouble2693]

We do that when I was in Saudi Arabia, when ever we want to cook our homemade whisky. Like your videos by the way. It's very educational. Keep it up mate!

[@johnharper8237]

Great video! Glad I ran into your channel through the video you made about waterproofing sheets and creating buttons! I like this video for the same reason: short, informative, covers all the steps clearly, and teaches me something that could save my life. Keep it up brother!

[@TareanSmiley]

Stainless steel is perfect for this application. That is why it is used in many laboratory and production setups, even as pressure vessels. The temperature required to make chromium carbide is not reached as long as a fluid is inside the container. Another improvement would be to design the coil in such a way as to allow it to be buried in dirt, which is then moistened, to improve the cooling and collection properties. One problem with this design is that a lot of steam still escapes, and floats away. By burring the coil in wet dirt/sand it improves the collection amount by a country mile!

[@Nighthawkinlight]

Yes all stainless would be ideal
