30 seconds may not seem like much, but consider that difference is between two and a half min versus three minutes... meaning the heat exchange version is around 17% faster... and if that isn't good enough then consider too how long your camping fuel tanks can run. If you save 30 seconds per cooking session then making 5 meals using the heat exchange saved enough fuel to count as a free 6th meal versus the plain cooking container. (That could mean the difference between eating nice cooked noodles on that last leg of the hike out versus eating raw crunchy noodles and drinking cold water with them!) So... I think you scored! You now have one more subscriber to your channel! Keep up the sweet videos!
That looks like the mockit rocket mk2? Have you come up with a better design? I am starting to get into the world of DIY stoves. I am going to start with the alcohols because of the ease and access to materials. I will probably make some of your designs in the future. Thanks for the info, your channel is great!
I think I found what typos RUclips ain't likeing. No space after the period,it thinks its a web address. Lame. Any way,that is a good possible reason my attempts have failed. I'm not using a thick brass. Hmmm. This is going to be a project, and lots of Coffey will be consumed. Is aluminum not good? It has a pretty high thermal conductivity from what I have studied. I doubt I need a blow torch to boil water but if I can figure out how to make it so its still fairly hot and the flame is widely distributed it could work.other option is a coil jet with heat exchanger. coil jets operate on similar principles.
+Richard Peterson I'm at about 7000 feet or 2133 meters. Water boils at a lower temp the higher you go, so it will boil sooner, and require longer cooking times due to the lower temp. I think I measured boiling water here at the house at 200 degrees F or 93 degrees C
+Richard Peterson You have some other comments that seem to have typo's that youtube thinks are external web addresses and as such they got put into spam. The heat sink fins would need to be on the pot to work, without a short and fast way to transfer the heat to the water, the fins would probably melt, or in the case of these soldered on ones, they would fall off. A SVEA type burner bell is something I have played around with in the past, it would need to be made from thick brass or copper. The thin brass of a door knob can't carry enough heat down to the vapor generator for a strong burn. I'm toying around with casting one from brass, but that's still in the "thinking" phase.
i am a welder by trade...and recently bought a jetboil...was thinking along the same lines as you about making a frying pan...my idea was to use silver instead of solder...silver has a higher melting temp...around 1100-1200 degrees if i remember right...solder is around 300...my thinking is that solder isnt as efficient as silver for transferring heat...as i have a tig welder i was also thinking about tiging stainless box tubing to the bottom of a stainless pan also...most likely even more efficient...was also thinking about angleing the tubes at about 30 degreesso the flame wouldnt go straight thru the tubes but insteadbe pushing up along the sides of the tubes...just my opinion
Yea, a frying pan would have a greater chance of the solder joints getting too hot because the lack of a volume of water in the pan. Silver would be a great conductor of heat, since you have the skill I say go for it! I did not want to waste a bunch of silver trying before I knew weather or not it would work.

Interesting video! i think 30-40 seconds is a nice and very positive difference in favor of the pot with the heat exchanger.

DIFACIL PROJECTS Thank you!

Yep, revised from the version I showed in earlier videos. Thanks!

What altitude are you at?and what difrance would high altitude make?

Also looks like mk3 on the door knob stove.
mk2 MOD 1 maybe?
