Bill,
this looks very promising (if it’s light weight).
what is its weight per unit area?
where are some good sources for it?
nominal approx. cost for a very small amount?thanks.
Sep 25, 2005 at 1:31 am #1341981The bad news is that most places sell the ceramic fiber on a roll 2′ wide by 25′ long. I think I saw an add from a place that sold it by the foot and will look for it later today. I will make an insulated cook pot so I can get an idea of how much it might weigh and boil some water to get an idea about boil time. I just did a bunch of boil tests so I have a lot of “before” times to compare with.

FYI, i’ve gotten dbl-posts by hitting the F5 Refresh button (or picking the Refresh menu choice).
Sep 25, 2005 at 4:04 pm #1342005Yeah I think I got the double-posts from using the back and forwads buttons. Didn’t push f5 or reload, so it wasn’t those. I think I set some sort of double post record

Nov 29, 2005 at 6:09 pm #1346180bill… that`s a great concept. another aplication would be having a pot in your emergency/survival kit just by having the foil & knowing how to use it. …slowhike
Nov 29, 2005 at 6:16 pm #1346181to go along w/ the thoughts others are sharing… i`ve worked on an idea of having something made out of foil, a little bigger than my pot to cover the pot & capture a lot of the flames & heat going up the side of the pot. just like turning a larger pot up-side-down over your pot. it`s just been a little tricky to make it colapsible/foldable, & therefore not bulky. …slowhike
Dec 3, 2005 at 10:07 pm #1346451Check out Nimblewill Nomad’s wood stove at Zen Stoves (LOTS of good stuff on this site). If made from titanium sold via thru-hiker it weights 2.7 oz (you would want the 4 – 4.5″ x5.5″ at $25. What I actually received from him from that order was five pieces as he sells the titanium for that particular stove.) The best pattern is on the Zen Stove site. That pattern shows a 6th piece that is missing in the photos. Some redrawing of the pattern may be necessary. Test on cheap stuff first.
Some weight reducing design modifications on the Nimblewill stove could include a perferated bottom and notches on the bottom edge. Titanium rod could replace the bottom. Also, I will test out two different wedge shaped versions – where the top is smaller than the bottom – to better fit my pots. I got a sheet of steel to play with before I cut up the titanium.
The wedge idea also came from a Field Stove I saw on a Japanese stove collector’s site. That stove is pictured under STOVES>OTHERS.
The Trailstove pictured below Nimblewill’s stove on the Zen site uses a blow tube instead of a fan to perk up the flame.

Dec 13, 2005 at 6:06 am #1346883Yukio,
Nice work on that stove. It reminds me of an idea I had once for a ti-wood stove… (because of the comment of two ti cups)Did you use Snowpeak Single Cups?
Dec 15, 2005 at 8:35 am #1346992試作1号ストーブでは、プラスチック製ファンが熱に弱くて失敗しました。234gでした。
この2号ストーブでは、内側の火室の下に
熱を避ける板を3枚重ねてあります。これによって
1時間の連続運転でもPC用のプラスチックファンが
溶けることは無くなりました。面白いことは
温度センサー内蔵なので、薪が燃え尽きると
回転数も格段にゆっくりに変化します。
途中で、薪は継ぎ足す必要があります。
もちろん、サイクロン燃焼です!欠点は12VDCで駆動することです。そこで9V電池2個=18Vで回転させています。ドイツの1200mAhのリチウム電池が「秋葉原」で安く買えるので、東京では幸運です。
次の予定は、1.5Vで動くモーターと金属ファンを作りたいです。300g以下で。
Dec 15, 2005 at 10:20 am #1347002Hmm… some interesting ideas…
If I understand correctly, ther are some boards / strips of metal to reflect the heat up into the can to protect the fan?
Also, you ‘cycloned’ the inner can?
Wow, there are some really neat items on that uniflame site
Thanks for the ideas, Yukio
====Translated by babelfish
Trial manufacture 1 in the stove, the plastic make fan being vulnerable to heat, it failed. It was 234g.In this 2 stove, under firebox inside
3 boards which avoid heat are piled up. With this
Even with continual driving in 1 hour the plastic fan for PC
Dissolving was gone. As for funny thing
Because it is temperature sensor built-in, when the firewood blazes
Also rpm changes markedly slowly.
It is necessary midway, for the firewood to succeed and to add.
Of course, it is cyclone combustion!As for fault it is to drive with 12 VDC. With 9 V electric battery 2 = 18 V it is turning then. Because you can buy the lithium electric battery of German 1200m Ah cheaply at “Akihabara”, in Tokyo it is fortunate.
As for the following schedule, we would like to make the motor and the metal fan which move with 1.5 V, is. Below 300g.

リチウム9V電池は、アルカリの3倍長持ちする。低温にも強い(-30℃)
しかも劣化しない。でも少し高価です。予備的な装備にも適している。
薪ストーブの電池と共用できるので、都合良いです。
LEDランプは、10000mcd * 6LED です。非常に明るく長持ちします。
Dec 19, 2005 at 8:16 am #1347195Thanks Yukio-san,
I had made a comment about my wood stove and that I used a 9V battery with it and also used the same battery for my LED. Yukio-san has posted information about a 9V Lithium that could be used to replace the standard battery I had shown in my pictures. This is a my version of his post using a computer translation for some help.
===============================
Yukio-san said:
A lithium 9V battery — Lasting up to 3 times that of a of alkali type. It’s power stays strong at low temperature and it does not weaken in the cold
(-30 degrees C). It is however somewhat expensive. It is suitable also for preliminary equipment. Since it can use with the battery of a wood stove in common, it is convenient. an LED lamp — 10000mcd * 6LED it is . It stays bright a very long time.
===============================Dec 26, 2005 at 1:20 am #1347467こんにちわ、Billさん
ご承知のように
日本では、
アルミニウムよりも熱的に弱いかもしれない
葉っぱ、とか 和紙 を 鍋(pot)に
使います。水が入っている限り、大丈夫なのです
ふふふふふ(笑)
by JSBJSBAug 18, 2009 at 3:36 pm #1521669Bill, did you ever do any more tests with this? It looks like a promising idea that could save space and weight for a low cost.

日本料理では、昔から”和紙”を使う鍋料理も行われています。
水が入っていれば、湯温度は100℃以内ですので
300℃以上の紙が燃え出す温度まで上昇しません。
実際に、焦がさない限り、数回は繰り返して使えますが
清潔好きな日本人は、あまり繰り返し使用は行いません。
かなりの耐水性を有する、3重構造の紙です。
一枚当たり、日本円では、10円から50円ぐらいです。
直径は、7インチぐらいです。
通常は、アルコールなどの弱い火の上に
形が崩れないようにバスケットを置き
特製の和紙で作られた、紙鍋を乗せて、水を入れます。
とても熱効率が良く、平均に温めることが出来ます。

Sep 1, 2009 at 12:07 am #1524148I have to agree that this wouldn't be something to thru-hike with, but as an evening project, it sure was fun. I made this by following the instructions found on this website:
http://www.origami-instructions.com/origami-star-box.html
I used heavy duty Al foil folded over to 4-ply thickness. The pot holds its shape when filled with water. It holds just under 2 cups. The product weighs approx. .9 oz, which is .6 for the pot, .2 for the underplate, and .1 for the lid.I did a few boiling tests on it. There are some problems with the Al foil, some already noted. Water finds ways to get to the bottom, which then drips into the burner. This was mitigated by adding another piece below the pot that could catch the dripping water. This eliminated the problem for a cost of an additional .2 oz. The four layers of Al foil allow water to get trapped in between layers. This isn't too serious, if you were going to use the pot at night and let it dry out overnight.
The biggest problem is the ease with which the foil tears. The appeal of using the foil is that the pot could reasonably be folded flat and packed away. I did a short folding test. By the second fold, a tear had appeared at the bottom. When I folded the pot back out, a tear had formed along one of the corners. Some of this could be mitigated by adding foil tape (I don't have any right now to see how this would work). If I had the tape, I would add it to the corners prior to ever filling the pot with water. While the walls become reinforced through folding, the corners remain 1 ply thick, so they could use more reinforcement. Even with the tear, the pot can still hold over a cup of water. In a pinch, it could still be used for boiling water, even without repair.
