Esbit burner testing

[Eric Blumensaadt]

So I’m still wondering: with these new ESBIT stoves, using the most efficient pot are any of them as efficient as a Caldera Cone, mating pot and BGET burner??

 

[DAN-Y]

Robert, view this video to see the type pot support I had used in my first test:

Eric, yes the 2 aluminum pot system is as efficient as a caldera cone system, maybe even better. The BGET is far better than the Trail Designs Graham Cracker. The 12 cm Imusa Mug aluminum windscreen can be used to hold a freezer bag full of mountain House while you pour water from the 3 cup 10 cm Imusa cup. The 10 cm cup nests completely inside the 12 cm windscreen/pot and can be covered with a plastic lid for storage.  Using this new set-up I’ll be able to boil 3 cups of water with 1 large Esbit cube. A 3 wire hanging system can be added, can’t do that with a TD system. This new system supports the pot and adds protection from the wind  just as the TD system does.

Great video, thanks! I’ve not seen Imusa before, by the way. I think you rolled ridgeline is a fantastic detail, especially for holding the pot in a cone. An elegant solution.

If I had an Asahi, I would roll it to produce a more robust windsheild with reinforced holes for the wire suspension. I have too many projects on the table to go further on this project. I do know for sure that the BGET is the most efficient way to burn Esbit. It has great possibilities to create very lightweight water heating systems. It’s an easy Do It Yourself item. Can easily be purchased also ;-)

Even Eric will agree the BGET is the way to go.

[DAN-Y]

Here is a set-up that would lend it’s self nicely to be used with esbit and to be suspended. Fully enclosed.

[DAN-Y]

Robert, this pot support design might be of interest to you and others for an esbit stove. I found the photos on another forum. Design is by “birdbrain”

I like the opposing triangles ;-)

[rmeurant]

Intriguing configuration, Dan. I wonder what kind of boiling time it delivers for a standard bowling ball with 2 Esbit tabs? I presume the interior is hollowed out for the water – how large do you suppose the chamber is? I can see enormous potential for the vessel, at least downhill, on a cold day…

[Roger Caffin]

Looks like a bomb to me …

Interesting – it’s not really triangulated, it depends on the stiffness of the apex folds, and the cylinders holding the ends preventing them deflecting too much. Though it is triangulated in plan. Folding structures (usually much larger scale) are of particular interest.

Which reminds me, the Esbit shields ought to have a simple aircontrol mechanism, to open and close the vents, to adjust the heat. I’m aware of your sliding lid to the tray, but I mean on a cylindrical shield, some simple over-cylinder waste-coat that reveals or partially or totally closes the vent-holes. Just part of the design mix of the PERFECT Esbit shield/burner v.3743, revision IIX.(viii).3cx.

The <span style=”text-decoration: underline;”>Bowl</span>ing Ball ;) reminds me of some very helpful Esbit information given to us by Aaron Sorensen.

On page 3-4 in this thread Aaron Sorensen got really good boil results using a bowl instead of a straight walled pot.

https://backpackinglight.com/forums/topic/101822/page/4/#comments

I had purchased some aluminum bowls to do some testing but got side tracked and never completed the testing. The bowl shape has got to have some positive influence on Aarons great boil times.

Bob Gross said he uses the same bowl also.

More testing of bowls versus straight walled pots needs to be on our winter agendas.

Interesting, the shape of modern day crucibles for melting metals. Why the bowl shape bottoms and tapering sides. Because they are more efficient at heating the contents?????

[Jerry Adams]

I like that thought process, yeah, good question

Maybe time for a test?

An interesting Q. I suspect but cannot prove that the ‘bowl’ or crucible design may go back a few thousand years. Primitive clay work.

Ah well, guess I’ll stick to my 3 cup anodized aluminum pot and TD Sidewinder ti stove with the BGET burner. My last longer trip with it was in Nov. of ’17,  the grand Canyon, N. Rim to S. Rim. Worked like a champ for both boiling water and true cooking.

That setup or the optional Inferno gassifier wood burner insert kit for wood has done well for me for several years in all seasons and temperatures. The Inferno insert is great for melting snow which is a “fuel intensive” procedure. That Inferno gassifier setup is hot!

When I use my handleless, ceramic lined “one egg skillet” I sit it on the two ti stakes that run thru about 3/4″ below the top of my outer stove. Love to fry omelettes and meat in it. (I’m a carnivore.)

P.S. Dan,

“WE DON’T NEED NO STINKIN’ HANDLES! ;o) Because I use a light pot gripper for the pot and skillet (and often for stuffing wood into the Inferno insert).

Eric, the closest thing I could find to a 3 cup hard anodized pot is the  OLICAMP Hard Anodized Light Pot, 1 L

Do you know of another aluminum 3 cup pot?

[Eric Blumensaadt]

Dan, My 3 cup pot is from Open Country, as I recall. It came with the Sidewinder. I dunno if they are still available.

My pot is lower and wider than the Olicamp pot you linked to. The “wider-than-tall” pot shape is tested to be more efficient – probably not by much.

I appreciate your continued testing of ESBIT stoves. We ESBIT fans read every bit of your postings and the replies. Fascinating stuff. Love the videos.

However I’m STILL waiting for that “detuned” solid rocket fuel tablet that will fit in some kind of flame controllable Ti stove (to withstand the heat). ;o) A boy can dream…

BTW, does ESBIT burn hotter than the old (and noxious) US military Trioxane fuel tablets?

 

[DAN-Y]

Eric, your pot has no handles. My experience shows a pot must have handles. Further research today shows I’m not in the minority. Many others have indicated the same thing…handles are a must. We all know the ole saying ;) Hike Your Own Hike. I prefer the KISS principle in design of kits and stove building. “Keep It Super Simple” I don’t like extra pieces :-)

I don’t recall if the Trioxane burns hotter.

[Roger Caffin]

Hi Dan

Well, you have to be able to pick the pot up, but most of my pots have no handles. Instead I use an MSR LiteLifter
https://www.msrgear.com/cookware/litelifter
Very stable and secure, and very light. Also featured in our review at
https://backpackinglight.com/msr_titan_pots_spotlite_review/

Cheers

[DAN-Y]

I keep the foil lid in place by leaving the MSR LiteLifter on top of it – that way I know where the LiteLifter is as well!

It’s just another piece to keep track of and a piece to fit into the pot for storage. But… I can see you need to stabilize your 2 person pot when stirring because the pot did not come with handles. Your other pot to the right has handles. ;) You had to “make it work” so enter the pot lifter.

Since your review in 2006, we’ve come a long way with pot designs:

[rmeurant]

Surely the idea is to use wisdom tech. In the first instance, by using telekinesis to move the pot, then when adequate mind control over matter is reached, to use mind control to directly excite the water molecules to heat them, thus obviating the need for physical fuel.
P.S. I always assumed MSR was an acronym for Metaphysical Synergetic Resonance..?

[Roger Caffin]

Hi Dan

You know, 2006 is a long time ago! Oh well.
These days I just take the large pot and leave the kettle behind. Less weight. Ditto for clear plastic soup bowls: left behind.

I am slightly puzzled about the pricing on the Toaks pots though. First 1.35 L pot $52.95; second one $54.95. Assuming I have interpreted the diagram correctly, why the difference?
On the other hand, pot 5, 1.6 L, $49.95: cheaper than the smaller pot.
Weird stuff.

Cheers

@rmeurant, hey Robert. I’m liking your idea more and more everyday.

I used a 12cm pot as a windscreen and pot coozie/cozy/insulator. I left the handle on it so I can pick up the 10cm pot that contains the 1 cup of boiled water that 1 cup of freeze dried food has been added to rehydrate. The 12 cm windscreen remains hot for a nice length of time to keep the 10cm pot hot while the contents rehydrates. Once the food is ready, I pick up the 2 pots and start eating. I use a 3″ diameter carbon felt disc to pick it up, the handle is still hot. The BGET and ultra light pot support are still under the 10cm pot while I’m eating the pots contents. Once I’m finished eating, I wash the pot and place the BGET inside it along with other items for storage. The 10cm pot then goes back inside the 12cm for storage. It fits a little below the top rim of the 12cm pot. The pot support is opened wide and stays inside against the wall of the12cm windscreen. Makes for a nice nesting, compact kit. Place it inside a stuff sack and I’m ready to go.

Top View. No flames come out from under the pot using a large Esbit cube inside a Titanium BGET.

And it can be supported by 3 wires when necessary ;)

Glad to read of it, Dan.With my system, no vent holes, the assemblage can be placed on ignitable debris (forest floor), and not set fire to it (though nevertheless, I watch it carefully).

[DAN-Y]

Robert. I can see your set-up has a shallow container to allow oxygen to enter around your pot and down to the esbit. My outer container is robust and can be used as a stand alone storage unit for everything and also be the windscreen. I don’t use an iPhone or gps unit to text while hiking so the extra weight of the kit is acceptable. ;)

If I were wealthy, I would purchase light weight titanium pots to make the kit.

I like multipurpose items :-) I like options! I like modifying. I like how esbit burns but dislike the stench. I let it burn till it’s completely consumed so as not to have to blow it out and have a cloud of stinky, noxious whatever it is fill the air.
