Күн бұрынGet You Own PaleoHikerMD Patches HERE!: www.etsy.com/s... Personally I have always seemed to HEAR that the sweet spot for the fancy feast cat can stove is 1 inch. That's 1 inch from the top of the carbon felt to the bottom of the pot. Well, is that correct??
In today's video we do standard two cup boil tests on stoves with 1/2 inch, 3/4 inch, 1 inch, and 1 1/4 inch heights...which will be best?!

Dividing the burn-times by the boil-times the 3/4 inch is the most efficient stove then. To boil 2cups (470ml) it needs 16.3g of fuel, compared to 18.3g with the more effective 1 1/4 inch stove. Or, comparing these 2 stoves: you can save 4,25 g/l using the 3/4 inch. Speaking to ultralight enthusiasts: being on a 5 day-hike, boiling two hot drinks of 0.3l each and a dehydrated meal needing 0.4l a day, you save about 21g of fuel. To all the others: I suggest to blow your nose one more time per day, in order to get rid of the additional grams.

Alternatively, you can just carry the 1" height and use some rolled foil sheeting as a "simmer ring" around the outside of the stove. Just cut the sheet height to about 1/2" shorter than the whole stove itself, then use a paperclip to form it into a 3" cylinder around the outside of the stove. Hiram had a good video a while back illustrating better than I can.

My cat can stove has been bullet proof for years, and I first saw it on this channel. Some mods I made: - used mini-vienna sausage can rather than cat can because it's a little taller and can hold more fuel. - cut off the wider rim and used it as a base for better stability. - use Rock wool tamped down between the cans rather than carbon felt. Never shrinks and stays secure. Glass fiber insulation might work as well. - use 100% ethanol ventless fireplace fuel rather than Heat so I don't have to worry about trans dermal toxicity of the fuel. About $7/liter but worth it for me. Thank you for introducing me to these stoves!

I realize that this is an old video but lately I have been thinking on this subject of boil time vs burner to pot distance. I am thinking that there may be another variable that is not discussed or tested in burner to pot (b2p) perfect distance testing. That variable is pot diameter. I am going to hypothesize that a wider pot *may* have a shorter b2p distance sweet spot than a narrower pot. I am going to guess that this "sweet spot" distance may be even more critical with a burner like the fancy feast which has a wider heat pattern along with a lack of direct heating to pot center. I am going to guess that there *may* not be as variable a "sweet spot" distance with a burner with a center heat source such as the Minibull Designs Gnome Turbo. Of course you do not need to, however if you are looking for more stove testing options, the hypothesis that I laid out here might be an option for further testing.

I have a 1" cat can stove and get fastest boil times when I use a pot stand where the pot is ~1.5" from the top-most part of the cat can stove. For example, using something like a Solo Stove Lite as a the pot stand can produce very good boil times, as the bottom of the pot is over an inch above the top of the stove.

I didn't read the other comments. Hope I'm not repeating something already said. Most who have watched a million hours of Hiram and experimented a little know that 1 1/4-1 1/2 Will give fastest boil BUT 1" is sweet spot because it gives you BOTH a fast boil time and a guaranteed 3 plus minute boil length to make sure you have killed anything if not using filtered water. There are other stoves that will give you even faster boil with same once of fuel but burn out is so fast you would not have safe drinking water after 30 second to minute boil. Hope that makes sense when others read this. Great video. Looking forward to your ideas to make wickless titanium clone blum faster.
@mildcamper5429 4 жыл бұрын
Exactly my thoughts also. If you do have all your water needs with you, then 'piping hot' will suffice using as little as 15ml (0.51oz) for ≈2 cups at a mug burn height of 1" (750ml titanium mug used). To Add: As PaleoHiker's first test showed, the lower height would actually be good for an extended rolling boil on less fuel at the expense of a longer boil waiting time. Good for real wilderness hikers.

I did see this with Hiram but still learning from this one as well. What I found interesting is the 1/2 inch. It took roughly 9.5 minutes to boil the water and lasted almost another 10 minutes. That tells me you can get 2 boils from the same amount of fuel (or... possibly boil twice the amount of water for the same amount of fuel - many factors start to come into play, pot size and shape, etc). Boil time is obviously much longer so if your hiking around the back country and need a quick cup-o-joe that's fine. In a survival situation, where you are conserving resources and boiling water to drink, I would prefer the 1/2 inch. Plus its more compact. Thoughts? More experimentation?

The sweet spot depends partially on the stove and the diameter of the pot.
@robertcwillifordii2630 Жыл бұрын
"the sweet spot" is most commonly associated with the personal preference choice between boil time and run time. The height of the gap plays the largest weighted role in determining that. There are other factors that contribute to overall fuel efficiency of alcohol burners besides ambient temp, what your pot is made from, or the water's starting temp. The most obvious factors are the use of a windscreen (or not), and a pot lid (or not), for heat conservation. A lesser known factor is the use of priming fuel, lit around the burner (not that fancy feast stoves or capillary hoop stoves need that, but all others do).

Just a suggestion: for a little more effort you can measure the energy efficiency of the stoves. Weigh both the the pan of water and fuelled stove before and after boiling. Energy efficiency is 'energy out' / 'energy in'. 'Energy in' is the mass of fuel used (from the change in stove weight) multiplied by the heat of combustion (27kJ/g for ethanol). 'Energy out' is the sum of two parts: 1) the heat to bring the water up to boiling from ambient = change in temperature * mass of water * specific heat capacity (4.186 J/g°C) 2) the energy to evaporate the water = change in pan weight * energy of evaporation (2257 J/g) Alternatively, substitute fuel energy with fuel cost.

I learned this before I knew who Hiram Cook was (2003). I kept raising the pot and found that, after a boil was achieved, it was much more furious as I raised it higher - to 1.5" and a bit more. It's all about air supply. Give fuel more, and it will burn hotter (and faster). I use sit-on-top, side burner stoves with large holes (Supercat). More holes draw in more oxygen and let more burning vapor out, the fuel brings water to a boil quickly, but then goes out quickly. Fewer holes, it takes longer to achieve a boil, but the stove burn time is longer. Here's my SECRET to achieve a quick boil AND longer simmer time in Supercat stove: Put an empty tealight candle tin inside the stove, fill it to overflowing, pour more alcohol in, and light. The alcohol will burn off more quickly around the tealight candle tin until it is gone, then, with less surface area to boil off, the candle holder becomes, in essence, a smaller stove within the stove, and it will burn cooler, allowing you to simmer for a few minutes. Filling just the tealight candle tin after everything is burned and cooled, will give you a very long simmer.

Your test was pretty much spot on. Hiram Cook had suggested 1-1/4” max but it was at the edge of wasting fuel. Had you used a shield that was about 1 inch diameter larger than the pot extending halfway up the pot or more the boil time would be reduced as much as 20%. The actual reduction in boil time depends on the size of the pot, the height of the shield, the gap between the the pot and shield, and the intake area dimensions at the bottom. The main reason it works is the heat is contained against the side of the pot. The height affects it because of the amount of surface the water is exposed to. Taller pots of the same volume work better because the heat is contained against the surface longer. It is particularly important if there is any wind that would otherwise carry the heat away from the pot. In reducing the boil time by concentrating the heat output, fuel is conserved. I use a shield on my Docooler (collapsible Solo gasifier knockoff) as well, not to conserve fuel but to reduce boil time.

There is a carbon felt (1/4 inch thick ) wrapped around the tomato paste can and 1/8 th inch above the Vienna sausage cans edge. The pot sits on the top of the Vargo Hexagon Titanium stove. If you were to set a pot on the tomato paste can it's 7/8 of an inch above the edge of the Vienna sausage can.

Use distilled water to get more accurate test results. From what I gather most people use the 16 ounce metal cups (think Stanley Adventure). I have great trouble finding the inner cans. Can you test again with using copper for inner can? I suspect more heat transfer when you use the taller can. Next testing - tuna can stove! It looks like a ratio there. Whatever the boil time then multiply that by 2 and that is about the run time. Different fuels will result in different numbers too. How about using lamp oil?

Efficiency = boil time vs fuel used. Faster boil times will obviously use more fuel to do the job. It takes a finite amount of energy to raise the temperature of a given amount of water to the boiling point. Much of the efficiency losses can be attributed to heat losses (conduction, heat running up the sides of the container, convection, etc). Too many variables to calculate the true efficiency other than to compare the boil time to the amount of fuel used.
@TimeSurfer206 Жыл бұрын
I think we're missing one of the most obvious reasons for the differing burn/boil times: The surface area of the inner can that's being exposed to heat. The taller the inner can is, compared to the outer, the more of its surface area is being exposed to heat. More heat is transferred to the Alcohol in the can, making it evaporate faster. More alcohol vapors means a bigger fire...

Just made one if these using a cut-off regular baked bean can bottom for the outer part and the bottom of a 330ml coke can for the interior with the bottom 'dimple' cut out (creating the top for the cup to rest on). I used a strip of cotton T-shirt to make the wick between the two. It works nicely, have to say. Once fuel was in it I tilted the thing and turned it around to let the alcohol inside soak up the wick to help it start. I cut it all with a knife so the cuts are pretty ragged but works fine all the same... Only issue is I get is two larger, yellow flames jetting out of the two breather holes in the interior can. I used a larger can, putting it over the top of the whole thing to put it out.

well you could use these results to your benefit.... one and a quarter inch to boil water, another lower one to simmer your food as it cook's. obviously the half inch isn't throwing out the same BTU's. less chance to burn your food as it cooks. 👍👍👍👍

I'm having a hard time understanding why the height of the tomato paste can affects the output of the stove?

this may seek like a dumb question. but how do you transport your alcohol stove? doesn't it leak out the remaining fuel? does the fuel burn off enough NOT to produce a smell in your pack??? i really do not know... thanks.
@mattmcguire1577 2 жыл бұрын
You need to burn off all the fuel. After a while you get good at judging how much you need. They cool quickly so if you don't have enough you can add more. Generally they don't smell after the fuel is used up. But if that is a concern, it is easily fixed with a snap lock bag or a container.

Hiram is still alive and well. He has a Facebook page and was still posting on there as of yesterday 04/26/2020. He just quit posting videos on KZfaq. My guess would be that he basically tested and tried everything there was to try at the time, and honestly nothing really different has really been made since then.

You should clarify what “1” cup is. Technically one cup of fluid is 8oz however if you use a measuring cup that would use for dry goods such as flour those are only like 6oz

Now see if the width of the pot, relative to the burn height, makes a difference. Like a Jetboil, a bigger flame can wrap more or less on the walls of the pot.
@JeepnHeel 2 жыл бұрын
As a general rule, the smaller the pot diameter (less efficient to heat), the more that lowering the height down from 1" is a net improvement. This is a compromise that hurts speed, but once you have a small enough pot the amount of "lost" heat escaping starts to outweigh any boil time concern. As an example, 1/2" heats my Toaks 550ml slightly faster, despite 1" heating all larger pots much faster.

Can you redo this test with the same size holes drilled in the sides? I feel like that has a lot to do with this. if they're much smaller holes then it seems like it would be limiting the amount of oxygen meaning limiting the amount of combustion happening I assume that would reduce the amount of fuel being used, and decrease the boil times. Please let me know if I'm wrong. This is just an observation.
@Sokol10 2 жыл бұрын
The combustion use oxygen from outside, the hole in upper part is just a safety measure for keep the internal/external pressure equalized, for when using a pot with flat bottom the internal pressure don't cause fuel overflow.

I'd think that the longer flame height would be more subject to wind caused heat dispersion.

OK this is interesting.Of course questions arise as they should with any experiment. Do any of the following factors affect the result : width of wick/size of pot/type of stove/type of fuel/wicking material/air or fuel temperature? (and probably several more questions) 👍
@JeepnHeel 2 жыл бұрын
The short answer is yes. =) The longer answer is that, in my experience, windscreen/wind outweighs most other factors. Second would be pot diameter -- the narrower the pot gets (less efficient to heat), the closer it should be to the flame source, even at the expense of boil times, due to the amount of heat lost around the sides. Wicking seems to have the least effect, as long as you don't go crazy in any direction. In most cases, I also found stoves to be most efficient with 1fl oz of fuel, so there is a case for overfilling & recovering if your stove allows for it.

5:38 "so here we go our last round with our 1.25 inch if if we can use a little bit of DEDUCTIVE REASONING I think that our boil time will start to get longer ..." Did you mean INDUCTIVE REASONING?
