I got asked to jump in on this post and share my thoughts... here are just a few brief ones:
1) A couple years ago I made pretty much this identical setup. Think at one point I had a video on youtube showing it, but I have come to hate youtube and pulled most of my videos I had uploaded, so cannot show how I went about it, but I used the same pot from Zelph, a custom made (shorter) stand from QiWiz, and I think just a flat sheet of Ti for putting esbit on and some Al foil for the lid.
2) It was, well, usable. I used it on a number of sub24hikes but it was just never good enough for me to make it beyond my s24h testing.
3) I think playing around with these kind of setups is fun and totally worth the time invested in the pursuit of learning SUL/XUL hiking. You learn what works and does not work for you. The awesome thing about backpacking is we all have options to use and go with different gear and use what works for us, eh!! I still have the pot and the stand somewhere, but they have never been used since I initially tested it.
4) It was just a little too little amount of water.
5) I believe that our gear, whether in the HH/UL/SUL/XUL world of hiking should be as full-proof against failure as possible. The can can too easily be squished. The stand has those little connector pieces that hold them all together that if you drop one in the sand, snow, thick forest floor, or whatever, they can be lost - I know, I lost two of them during my s24h testing. Both of these place the cook system into the 'too high of risk failure' for me.
6) If given the option of a 6 g stand that has parts that can be lost, vs an 8 gram wire mesh stand (say, one of these cut down in height) I will choose the 8 gram one. I want reliability in my gear and the reason I try to promote sub-24-hour hikes so much is because they given folks a chance to really learn what is just not going to work for them before they go out and hit the longer trails. I am not saying this setup will not work for Jeremy - not saying that by any means at all, it just did not really work out for me. So, I choose to ditch the stand and the too-small-for-me cup and bounce up to a wire mesh stand and a slightly larger pot.
7) Tealight holder. Jeremy, what is your purpose for that? Unless we know WHY you are using that, its just an unknown. (a) Are you using it in an attempt to provide efficiency to your esbit cubes? (b) Or is it to prevent esbit sludge for going all over the place? (c) Are you using it as a ground protector? If you are using it for efficiency, you can give up... its not tall enough to deflect wind, not tall enough to help focus the flame, and the material is too think to store heat transfer. If its to prevent esbit sludge, well, that I understand and that is all I ever used a teacandle holder for. (c) If it is for ground protection, sorry but that is just not enough. Even the all-too-typical .005" thick titanium that companies enjoy packaging these days as part of a 'complete kit' is not thick enough. I have almost started a few ground fires because of not having a thick enough ground protection when using esbit. I have found that one of the few things that really works is a square cut piece of carbon felt. ref. What Bob Gross wrote is dead-on right... a tealight holder is just not durability enough for the long trail. The easily get squished and after a few times the metal starts to split.
8) What BG wrote... "invert it to burn Esbit"... is actually a rather interesting idea. It would (a) raise the esbit closer to the bottom of the pot (if needed to reach the best efficiency height of esbit<->bottom of pot... which I do not remember) and it would also (b) get the esbit off the ground a little higher and thus help with lighting any pine needles or whatever might be on the ground. One thing would be... would that gap of air that would be inside of it cause efficiency issues?? Unknown to me, but others here have the knowledge of that.
9) BGET or legless BGET... oh boy, lets hope Brian Green does not hear us talking about leggless BGET's :-D Umm, I guess what we really need to address here is "does a pot of this size, with this little amount of water, really justify even worrying about efficiency?" I mean lets just be honest here, a little 4g esbit table is about all a person would need to bring this amount of water to a temperature good enough for your tea/coffee and almost warm enough to be viable at a meal rehydration without it being too cold. Go with a 4g and a 4g broken in half, so you have 6g and you can (should??) be able to reach the 200(f)+ mark with this little amount of water (have you tested this yet Jeremy??) So, anyway, my vote just goes for doing away with the teacup and/or the BGET. If the goal is to have the lightest setup possible, carrying either/both of them make no sense as they are just not going to provide a viable amount of efficiency. Lets remember, the fastest way to get water to boil, and the hottest way to get esbit, is without any of these kind of things... just the straight esbit set underneath the pot. All these kind of things (BGET/TDGC/FF14) really are designed to do is give you a longer burning time, not to give you a faster boil time.
10) DS said: "I also have one of Zelph's pots. It's small. It can be easily duped using a Blue Diamond Almond can (the short pot doesn't need ridges, IMO)". Ditto and totally agree. I bought a few different size BDA containers when I was playing around trying with this same stuff.
11) Adam said: "why not also replace your pot, so say use a cut down soda can"... I did this too. OMG did that little soda can get hot!! And stay hot too. It took almost 20 minutes for that little Al can too cool off enough to pick it up. The thinness of the Al over the thickness of a beer can surprised the heck out of me in regards to how long they stayed hot. Learned my first time using a soda can that they are not a good idea LOL.
12) BG said: "All of the ones that I have here weigh 0.4 grams." -- Dang BG you scored on your tealight holders! All the ones I have are 0.59 grams. Maybe its the green paint on mine LOL.
13) Jeremy said: "I am thinking about putting 10 or so of these setups together and selling them for 40$ or so". Uggh, I think that is kinda priced over the top Jeremy. I think the average SUL/XUL hiker is just not going to put out that kind of money for this specific setup. $20 bucks, maybe... if shipping was included. Unfortunately, and yet the reality is, this is just too small of a niche market.
14) But even more than that, I think that part of the adventure of going from UL to SUL/XUL is the exploration of testing and trials and successes and failures. Folks buying their way into SUL/XUL is just not a good thing. The idea is (and especially with XUL) to learn along the way, not buy your way in. Playing around with different setups, learning what works and does not work, for you as an individual hiker, learning where that 'point of putting myself at risk' is at -- all of these things are the type of things we should be encouraging. I admire your own exploration in having the lightest possible cook setup that you can - I did it myself and still find that quest trying to suck me back in every few months. Have fun with this, keep learning, keep experimenting, keep sharing with others -- all of that is what all of this is really all about!!
(ugg that took me an hour to write up... I gotta get back to what I was working on before I visited BPL tonight LOL)
