Capillary Hoop Stove - universal -

Marriage of hoop and capillary technology. This is a one of ultimate alcohol stove.
SPECIAL THANKS
This is the state-of-art alcohol stove system that is concentrated technological strength of Japan. My master JSB-san, comrade eizo-san and my idea are crammed.
Until here, of course, I've been influenced by the ideas of jonfong57-san and Fuzzy's Lil' Stove.

[@howardberry2658]

I just made one - my first can-based alcohol stove! It took about 2 hours from start to finish, including sanding off the paint. AND IT WORKS!! Many thanks Tetkoba-san. In the UK, you can get Diet Coke cans the same size as Red Bull. Next time. I'll sand the can before emptying it and drill the jet holes before fitting the top ring.

[@erich1394]

Thanks for the diet coke recommendation - hopefully I can find it in the US because Red Bull is expensive as heck and I know I"m going to mess it up a few times!

[@jerryweil7053]

Tetkoba, you and your friends have designed one of the most elegant and easy to make alcohol stoves I've seen! Thank you for your efforts and generosity!

[@kurtmcdonald7113]

This is a great design. I've been messing around with a slightly different jet pattern and size. A stove I just made yesterday is boiling 500ml of water in only 4:15. I'm using V8 tomato juice cans in 5.5oz size. The final height of the stove is 38mm. The jet pattern I'm using is 10 jets, with alternating size of 0.85 and 0.65mm. I'm using 20ml of denatured alcohol which burns for 5:00-5:30 total. The kettle I'm using is a MSR Titan 750ml titanium

[@Liberty4Ever]

I built a variety of alcohol stoves many years ago, with a fairly deep dive into engineering for simplicity and efficiency. I'm preparing to embark on a new time wasting recreation to create a fast boil stove for tea and the occasional freeze dried pouch of expensive salty disappointment, and a long burn simmer stove for pasta and rice dishes. I have a pile of 5.5 ounce V8 cans queued for the experiments. I think I'll make a Spiguyver (capillary) stove for the fast boil and my own non-penny version of the penny stove for the slow simmer stove, although I can't help trying a super simple version that's basically a squat can with eight jet holes in the side near the top.

[@Road.Tripping]

As always, your stove is a triumph of beauty and function. I would love to see a more detailed video of the forming of the creases as I'm not sure I understand teh process for making them. Well done!

[@Throughthebit2000]

Tetkoba san, your creations are fascinating to me. Using some rough numbers, it seems that this CHS universal version puts out over 1 KW (1120 W) of thermal power, and bringing to a boil 400 cc H2O required about 140 KJ of energy. So your awesome stove was around 35% thermally efficient. Better than any that I’ve seen anywhere, by a long shot. My sincere respect and admiration!

[@VinceTibo]

This is awewome, and for more than one reason. Not only the stove is an amazing piece of work, but the whole video is entertaining and enriching. The explanations are quick, efficient and clear, the music is perfectly chosen, the graphics are helpful to understand how the stove works, and there are nice tests made at the end of the video to show what to expect from the design. I cannot think of a better way this could have been made, thanks a lot!

[@winstonsmith1183]

The best. Ingenious. Should win a prize.

[@tetkoba]

Thank you for comment. I believe potential of this stove is very high. Try this if you'd like to make.

[@charlesmichaels6648]

@@tetkoba Thank you. Excellent design. So simple. How did you cut the can so perfectly???

[@ReddHerringg]

Took this stove on a 3-day hike. I've been using penny stoves/can stoves for years, using lots of different designs, and this is simplest most efficient alcohol stoves I've ever used. Now if you can only design a simmer ring for extra long burns, it'll replace all my other can stoves :)

[@somedude1566]

Your videos are a real pleasure to watch! So much excellence here!

[@paulosullivan3472]

This is very impressive, I have seen other capillary stoves but they have always had somewhat complicated builds. This is simple and effective, very clever!

[@123-v9e-s4y]

Awesome design, Beautifully crafted and great production video, so clear. I'm definitely going to have a go myself. Thank you

[@dalusa7601]

This is the excellence in your work. Congratulations! ... and thanks!

[@nj4x4fever2]

I would love to see these stoves tested outdoors on a windy day. I like all your stove designs they are fantastic.

[@hazmat983]

Tetkoba-san, You are the BEST stove builder HANDS DOWN! Your designs are innovative, technically superior and (as luca bravo wrote) exquisite. Your videos are well done and I enjoy watching them. I built a CHS today following your video and tips and it turned out perfect. I did a side-by-side comparison against the specs in your video and the weight, burn and boil times were all identical. I love this stove! Keep up the good work!

[@tetkoba]

Thank you for your trying! Yes, I think CHS has a ultimate operating principles. It is a still developing technique. I hope many people try this and evolving.

[@erich1394]

Thank you for bringing the concentrated technological strength of Japan to the world of alcohol stoves - we are all better off for it!

[@user-hi8yo3kv8r]

JBウェルドを使わないトルネードのアルコールストーブを作れないかなと思い、色々動画を見ていたので、こちらの動画はまさにドンピシャでした。 立ち上がりの早さも火力も見た目のキレイさもイメージしていた以上で素晴らしいです。 製作はかなりシビアな様ですが近々挑戦してみたいと思います。 しかし不思議なのは、完成度の高いアルコールストーブの動画はどれも日本語のコメントがとても少ない事です、海外からのコメントが圧倒的ですね。 日本人はこういう工作に興味ある人は少ないのでしょうかね、こんなに楽しいのにもったいない。

[@tetkoba]

隙間を完全になくすにはかなりの精度が求められるんで、結構難しいと思いますよ。まあ多少漏れていても充分な気化量があるんで実用には問題ないですが。ひと缶で作るeCHSのハウツー動画に、JBweldを使わない方法も紹介してるんで、そちらも参考にしてくださいな。 日本の方々は欧米の皆さんに比べて長期トレッキングの経験が少ないでしょうから、シビアな環境だったり総重量だったりの経験が足りないんでしょうね。だから良し悪しの判断もつかない。よくある逆輸入じゃないと良いと認識されない日本人的性質の表れと思ってます。

[@svriderpokey]

What is your ultimate goal? All of your stoves are amazing, sir. Thank you for sharing your genius with us all.

[@FlashGeiger]

Yay, I made one of these last night and it works well. First burn test this morning... maybe I'll do a boil test tonight. I had some problem with the small holes required... Normal drill kits don't go down this small here, and a pin isn't strong enough to go through the can at this point. Finally found some smaller drills yesterday. Success. Thanks for the elegant design, tetkoba.

[@svriderpokey]

I just finished my first alcohol stove! It was a simple soda can penny stove design, but I aimed the jets in like you do (but straight, not cyclone). The 16 jets were made with a thumb tack (maybe 1mm). My first burn was with 80mL of fuel. At 1:40 it turned from a dancing blob into a bright blue solid primary cone with a beautiful blue dancing spirit above it (no orange). The spirit began to die @ ~47:00, and the flame went out at 52:21 Thank you for your examples and inspiration, tetkoba san.

[@niltonsilvia7496]

O melhor queimador feito até hoje. Fantástico. Parabéns 👏👏👏👏👏🇧🇷🇧🇷

[@beageek2]

Again I am amazed by your skill and ingenuity. Your videos are also well put together. Keep them coming.

[@Raku777]

Thank you for sharing. The video is a very good demo of some important design improvements. I like how time till jets go on has been reduced to just 5 seconds and that they run a full 10 minutes on very little fuel. These features, combined with the ease of making them (with no JB weld! Very good), is inspiring.

[@szwow4747]

I just made one using this tutorial. It looks almost exactly the same, works great. It took me some 4 hours but it is worth it. Thank you dude!

[@getsmarthypnosis6850]

Fantastic! By far the coolest, easiest, and best flame that I have seen. Thanks from the U.S.

[@BrandonHog]

You are the master, Tetkoba! Thank you for your detailed instructions. This stove is incredible! It worked far better than another design I tried.

[@neubeginn3428]

I builded this today and gave it a try. Burns Well an Not so uncontrolled like others. But for the cost of the three needed Cans. I can nearly buy one.

[@blesseveryoneiknow]

best stove with amazing music and state of art explain, exquisite craftsmanship

[@outdoors-university]

Thank you for sharing your knowledge with all of us !!! God bless you !!!

[@dkoriss1]

Thanks for sharing, really capable little stove!!!

[@SpaceMonkieC]

Hi, thanks for spending the time and effort experimenting to create this simple and beautiful stove. Have you considered placing the capillaries at an angle and experimenting with variables of angle and smoothness of the surface by using different grit when sanding the interior components? Thanks for sharing your work.

[@BMK1957]

Another great job,will have to try this one.Thanks ,your stoves are the best

[@supersilve]

Thank you for your reply i preferred to use a little JB weld between the joint to ensure an airtight fit. It works very well, I also tried a 57mm dia can and added one more jet and also 5mm to the height. the larger version is very powerful and good for boiling 4 cups of water with 40cc fuel, I think this is your ultimate design. keep it up

[@teatowel11]

I finally made one of these using 200ml solo cans. Its not very precise but works well despite not being as beautiful as yours. Hot tip, 🔥 don't over hear the rim when annealing it to fold it over.

[@1OTDM]

tetkoba, all of your work is highly inspirational to me. I plan on building this model soon. Thank you!

[@Rantsville]

Have built several CHS-U stoves and though not so pretty as tetkoba's perfection the stoves are amazing. If not perfect each build burns at claimed burn time for amount of fuel with flawless operation. Worth the extra effort versus other builds I have tried.

[@Tula0857]

Best of the best! Great Learning and really enjoyed watch through your series of development.

[@jonfong57]

Excelent design and fantastic instructions! The evolution of this stove has been great.

[@bigoilbyebye]

Thanks so much for showing this. I always have been inspired by your craftsmanship as well as your constant development of alcohol stoves. If you have an ebay, I may just purchase one of your units! LOL!

[@bluejeans8001]

Another excellent video and your new design certainly looks like a winner. Great job!

[@raymae60]

Your video is a work of art in itself. Rather than support Red Bull, consider V8 juice, small can (or larger can if larger stove is needed). Thanks for sharing your genius.

[@tetkoba]

Yes, the V8 cans are the best. But it is difficult to get the V8 here in Japan.

[@thapana56]

tetkoba... You are the stove guru!!!!! Thanks for sharing your idea.

[@JohnZBrown]

Very slick! I like your professional presentations, no speech, just music, unlike so many of the usual crop of ditherers who drift off topic, ummm, ahhh, backtrack, or get interrupted by other irrelevant events in their workshop, or have infuriating camera-shake. You only have the key items, clearly shown, in sequence, with text where required. And it works. This is why almost all Japanese stuff works, and is reliable, just like Toyota, as it's all attention to detail. Good job, guys. :-)

[@tomjeffersonwasright2288]

+John Brown And the videographer is gracious to present an explanation in English before his own language. His manners set a high standard for all videos to follow,.

[@geraldhenrickson7472]

+John Brown... Gosh John, could you please practice at giving a compliment without insulting others or using sweeping generalizations ? Perhaps using just the first seven words above along with the last three? Lastly consider that there is NO relationship between a presentation and the quality of the product presented. either one, or both, can be bad or good. Just some things to think about...

[@barrybridge3946]

Great video, thanks for posting. I have just improved performance by using some fine copper wire taken from a dimmer switch. The copper wire slightly proud of top is heated by the flame which then heats the methylated spirits. Big flames!! 😈

[@AZN9394]

Longest video I've seen so far from you. Great burner. Will try to build one as well...

[@edreynolds2819]

Excellent! Thank you. I will use this on my sailboat at sea.

Thank you for an excellent video of a very good design.

[@geraldhenrickson7472]

Fantastic design and execution. Thanks!

[@everynamewastaken1]

Thank you for your time tetkoba-san! I look forward to trying this. Go Japan!

[@BosisofSweden]

Loved this video. It's seams to be a very effective alcohol stove that burns 30 cl alcohol in 11 minutes and boils water in 5 minutes. More efficient than the Trangia alcohol stove. Higher efficiency also means higher alcohol consumption.

[@samhain9394]

Higher efficiency means lower alcohol consumption. Faster boil times generally mean higher alcohol consumption because they're creating more heat quicker, which often also means more wasted heat alongside that. Faster boil ≠ "more efficient." Less fuel used for same temperature raise = "more efficient," despite the amount of time taken. 👍

[@GeoN0JRJ]

looks like you have a winner my friend! Very nice work. Thank you for sharing

[@Nai1216]

This is one the favorite stoves you made that I like to date, the best

[@BenedictTanShanWen]

完璧!!!! My jaw dropped when you picked it up!! I am very interested to see if you can achieve jetting with this stove design at low temperatures :)

[@konp8685]

Great video. Think I will try to make this for fun. From the videos I seen so far on alcohol stove, the best distance between water pot and jet is approximately 1 inch or 25mm. With that kind of intense heat you have on this stove, I think it can boil much faster. Good job.

[@ARCSTREAMS]

very lovely work of art master tetkoba,,,but you say only 1 oz fuel was used? seem more like several ounces in that beaker,,but i bow to your work and craftsmanship

[@guiltygearcore]

Yep this one doesnt need a weld. Nice one!

[@mustang774]

Awesome stove you have created. Thanks for posting this great video. Take care, Bluefin.

[@lighturpl3]

[@sbrescue23ut]

Best yet! Thank you for sharing your masterpiece

[@T3hJones]

Gotta be the ultimate stove.

[@tetkoba]

Yes. Power will be down when smaller center hole. But it is more effective to close the jet hole.

[@egorbiohazchem]

thanks, here I am camping with your stove on top of a small upside down stainless bowl with the bowl I cook in supported by three tent pegs in the ground surrounded by a disposable oven tray. small red bull metho stove in action I find the base you cut off the capillary tube makes a great extinguisher or dampener to slow cook too.I shall try the chs side burner next as it would seem to eliminate the need to get the distance between the pot and the cooker right

[@lastdollarfilms]

Planning to make one of these in a day or to and will change one small thing just to see what effect it will have. I'm going to angle the crease so the alcohol is being sucked up the same direction of the jets. I do not think it will make much difference but I'll post back here if anything noticeable happens.

[@tetkoba]

That's great. I'm looking forward your post.

[@rogerbeers2939]

This is one amazing looking and operating alcohol stove, congratulations!!! Don't know how you will top this!

[@charlesmichaels6648]

Thank you. Next, 1. Cap for alcohol storage (excess fuel). 2. Damper for simmer 3. Stand/windbreak. (Stable, for outside)

[@Druetty]

Excellent as always! I will be trying this one for sure.

[@tikisailor]

Very cool stove, I have made other stoves you have designed, and soon I will build one of these.

[@loldozer]

Elegant video, intelligent design. Love it.

[@AquaDogTTR]

***** Hi Tetkoba, I just have a few questions about the CHS-SB., 1.How many creases did you put in the CHS-SB? 2.Should I put 16 or 18 creases? 3.How does the number of creases affect performance? 4.IMPORTANT:After completing my CHS-SB and after folding the outer to inner I drilled my jet holes 10mm from the top of my stove and it was less far from the top of the stove as what it looked like in your video of the CHS-SB. In other words, I did what you told me but, however, there was a bigger space between the jet holes and the top on your stove then my stove. What should I do About that? Thanks Tetkoba! Keep up the great work!

[@tetkoba]

Aqua Dog's Adventures in Toontown Rewritten ! 1. Forgot.2. as you want. 3. short burn time and more power when many creases. 4. Position of the holes farther than 10mm. Meaning of "10mm" is increment value of height of top piece.

[@layneoliver8673]

Hello TetKoba, What elevation do you test your stoves at? I built a modified version of the universal hoop stove eliminating the lower hoop and inner jets I stopped the capillary tubes half way up the inner capillary section and jetted it to the outside at this point. The results were stunning 3:40 min. boil time using tap water and denatured alcohol with a burner to pot distance of 1 1/4"-- @ 4600' elev. and room temps. using a typical titanium 1 quart. backpackers pot and lid. I have since built two more of these stoves experimenting with jet height/size and have had favorable results! My background is Field testing for outdoor equipment companies and have, over 40 years+ got t use just about every type of stove and fuel source available-- this great alcohol stove simplicity and performance that we are seeing especially with your stoves, got my attention! Thankyou for all the great video's and guidance! Lightning Layne-- Professional field tester at large!

[@hotsauceislethal9430]

congratulations, you are a true genius

[@jardinesdealimento3504]

Excellent idea and execution !

[@tetkoba]

Thank you. This is easy to make and very effective design. Try it!

[@jardinesdealimento3504]

I will, in fact, I would like to tweak it so that it burns very slow… I don't know how long you can make it last. While this is awesome for cooking, an indoors alcohol based oven (your stove covered with 2 masonry pots, like I saw on a video) might also be possible to get. I think it can be very useful to warm the room cleanly and cheap. What do you think ?

[@drewparrott]

Great job on the stove. I don't know how you're going to top this one.

[@cafeaeste6219]

Beauty by simplicity...

[@1OTDM]

I made a side-burner version of this stove, only issue is that it is longer burn time with stove sitting right on can. Ultimately I feel you probably still need a stand even with a higher lip and sideburners. I will test boil times with stand and maybe see if my hypothesis is correct
