Mr.tetkoba

He made a lot of stoves in this year.

Most favorite masterpiece is "Tornado Wick Jet Alcohol Stove"

* Sufficient firepower
* Beautiful tornado
* Rapid boot(within 7 seconds)

I'm impressed.

Sweet!

I always look forward to Yukio's stove postings here.

At first, they can be difficult to understand. But that just causes us to pay closer attention to the videos and still photos.

--B.G.--

I'd buy one if the price was right.

Yes, Yukio often has interesting items to show.

He tells you how to make it!!

I've been following our friend Yukio's alcohol burners. Then I saw one of their video clips from a 2 gram alcohol burner. You say "Two Grams? Ha!"

Well, I whipped one out. It isn't particularly neat, but I figure it would get beaten up a bit from use, anyway.

The alcohol burner weighs 1.9 grams, and the windscreen/support is another 1.9 grams. Obviously, it is not going to boil a big pot of water, nor is the support going to hold up a big pot of water. So, there is some work here to make this more practical. I boiled 6 ounces of water in a recycled aluminum bean dip can. The burner was rather slow to bloom, but once it got going, the flames filled much of the windscreen (which I had sized to support the aluminum cup). I can probably speed up the bloom by putting an insulator underneath the burner.

Anybody should be able to make one of these, and perhaps make it better. I used two aluminum tealight candle containers, plus a narrow strip of Foster's can aluminum on the inside to make the low pressure vessel, plus a few drops of JB Weld. The windscreen support is just a wide strip of Foster's can aluminum punched full of holes. You might be able to beat the weight using hardware cloth for the support.

Ordinary hand tools, a nibbling tool, a pin, and minor stuff.



Edit: If you look into the center hole, you can just barely see the low pressure wall.

Nice, Bob!
No windscreen around the pot? Who cares, at 3 grams that is a LITE stove. A piece of Aluminum foil can't add too much more weight!

Amazing!

I think, feel free to make first, and then continue to improve.

You can complete something better soon.

I have always sought to form, there is a lower form.

this is fine lower form :-)

Wow ... that guy is on a different level completely.

Take my money!!

Based on a design by James Marco. It's basically a simple chimney stove.

This design was discussed on this thread http://www.backpackinglight.com/cgi-bin/backpackinglight/forums/thread_display.html?forum_thread_id=56024

Weighs 3 grams on my scale- it's not super fragile, actually boils water... yeah...

Here is the two gram stove vid Bob is talking about.

Isn't that an amazing stove? Fabulous build quality, and is that flame pattern cool or what?

I wonder what kind of fuel consumption is needed to boil 500ml of water.

Pretty cool little stove, Bob. It's a miniature version of the stoves people build with aluminum beverage cans. How much alcohol can it hold?

"How much alcohol can it hold?"

Mine seems to fill up on about 7 or 8ml of alcohol. However, I think the optimal amount is less than that because of the way it works. Such a small amount of alcohol explains why you can't boil a great amount of water, and why you can't boil it rapidly.

wicked stove Yurio. Do you know how much it weighs?

HJ, size matters.

My burner was made out of two tealight containers plus some extra aluminum scrap. Each of these are about 1.4" in diameter, and about 0.35" tall. However, I've seen other tealights that were taller, maybe 0.5 or 0.6". So, I think that would be a good direction to head if you were trying to increase the fuel capacity.

Again, I think you are asking a lot of such a tiny burner to try to boil 500ml.

"Pretty darned cool, though."

HJ, that is not a nice thing to say about a stove. You meant to say that it was hot!

Thanks again to Yukio and our Japanese friends. I look forward to more of their ideas.

--B.G.--

Yeah, I can envision somone headed out with one of the tealights, Yukio posted about. For a single overnight, a great little set up.

Weight is Fair

Dual purpose is Excelent (remove the heat deflector on top and bottom, add a few vent holes for oxygen intakes. Use it as a cup holder/pot stand. A 4hour light at night.)

Size is excelent (you need a 4oz bottle of fuel, though.)

For XUL packing in season, it looks like a good little item.

This (tornado wick jet stove) is one of the coolest alcohol stoves. Kudos!

Many of you may be familiar with this site: http://zenstoves.net/Stoves.htm. It's a great resource for MYOG alcohol stoves.

My pressure jet stove is by far my favorite that I have made to date. True it does take priming, but is way more efficient (vs. my open jets.)



I am now in process of building a pressure jet/tornado hybrid. I'll update with the results.
