Full build new super-efficient alcohol burner - DIY MYOG

[@nvalley]

Thanks Tom! One note: there's about a minute of dead space in the video at the 9:39 mark. Looks like it starts back up around 10:42

Also, I'm curious how this performs in cooler weather. Does it take longer to "bloom" with increased volume that needs to be heated to pressurize? That could be an interesting test

[@tomlovesdiy]

Strange. Thanks for pointing it out. I'll fix it.

Back from vacation and fixed it. Thanks again.

I haven't tested in cold weather. From what I've seen on KZbin, colder temps don't have much effect on alcohol burners. Might need a couple ml's more priming fuel. Could be a challenge to get valid results; lots of factors. I don't hike when tremp is going below 35F. But I will definitely try it later this year. Oh... and when I used a liquid fuel Optimus stove it burned great in 20F.

It would help to describe the original can. I think it is Cheese Wow!? Had to slow it way down.

[@tomlovesdiy]

Good catch. I've made a couple other videos about the burners. Usually mention or show the can. This is a Walmart Cheese Wow. Also used Easy Cheese. I will add a note in the description. Thanks!

How is this what’s the main difference between this one and a penny stove?

[@tomlovesdiy]

Great question. Technically it is a penny stove because, as you saw the center fill hole is covered be a metal disc. It doesn't have to be covered. I do to better manage the burn rate. Uncovered it will tend to be faster. I designed it to be optimized for fuel heat transfer with the "penny" on the hole. I haven't tested with it uncovered. Guess I'm not done. Thanks for asking.

I see you only use 8 jets... OK .... Im new at alcohol stoves, I see people punch more than 8 and then some, cool to know..

[@tomlovesdiy]

Good catch! There are a lot of burners with 12 or more jets. I've done 12 but found that 8 or 10 are best. That gives my burners a good efficiency. I actually hit on 8 because I covered 4 of 12 on a whim. Keep in mind that I use sqirt cheese cans. They are smaller diameter than standard beer cans.

You said an .0135 hole was used and you're thinking of .0125 size hole, I like how you DIY, I'm looking at perforated stainless for a multipurpose windscreen and pot stand over an Altoid perlite tin. I'm having fun, this is all new, Best

Interesting! When you finish it, please send a pic to [e-mail]. And yes, it's very fun. Thanks.
