Not mine but I thought this was worth sharing. Not that I would ever do it or advocate someone doing it.
Apr 23, 2010 at 10:46 pm #1601474I guess you make a stand to hang your pot from once in the woods.
May 5, 2010 at 5:13 pm #1606642that doesn't look too safe. plus it sounds like a Pocket Rocket.
May 5, 2010 at 10:40 pm #1606781I wish I could understand what that guy was saying. The thing does sound like a jet engine but it did appear to function safely. The person who made the video clearly had little concern over the safety of operating it. It looks scary to me though.

Yeah. The 'stand' looks a bit rickety, and I wouldn't fancy having that pressurized can of hot alcohol drop out on it's side and spray a highly pressurized jet of burning liquid alcohol in my direction.
"Light blue touch paper and stand well back."
The claim of boiling a litre in 4 mins is pretty impressive though. Anybody miake lightweight asbestos suits?
May 5, 2010 at 11:09 pm #1606796I am kind of siding with you and the rest here Rog. I mean pressurized alcohol stoves are cool and all but this one seems to have taken that good general concept to the point of riskiness the longer I sit and think about it.
Here you go Rog Nomex
May 5, 2010 at 11:15 pm #1606801Oh I'll be having a play with the idea. But I'll be wearing a wetted balaclava and canvas jacket, goggles and gloves when I test it. 8-)
May 5, 2010 at 11:19 pm #1606803See my clickable above Rog.
May 5, 2010 at 11:37 pm #1606806Thanks, but I'll stick with wet natural fibres.
May 6, 2010 at 12:25 am #1606811Actually … it isn't much different technically from a vortex canister stove. I found it VERY interesting that the flame was so stable. Hum ….
Cheers
May 6, 2010 at 3:58 am #1606826Regardless of safety, this is a pretty awesome idea. Well done.
May 6, 2010 at 11:34 am #1606972What language was that? Portuguese?
It seems a bit impractical as is. I mean, where do you put the pot?
But the concept. Hmmm. Very interesting. Wouldn't it be nice to have a nice lightweight alcohol stove but with a bit more power, particularly when you're in "spring conditions" where there's snow on the ground?
Got something in mind, Roger?

May 6, 2010 at 12:39 pm #1607005The stand doesn't make a lick of sense, from a safety standpoint. It seems the real requirement of the stand is to give space between the primer flame and the stove, and block the wind. I'm sure a better stand could be made to satisfy those requirements.
In terms of safety: consider that he only put a couple ounces of fuel in a 12 ounce can. there's a lot of room in that can for vapors and so forth to compress before getting to a bursting pressure load. I wouldn't be surprised if you could run that stove completely out of fuel long before getting to some danger point.
May 7, 2010 at 8:19 am #1607362The impression I got was that the video wasn't intended to present a 'finished design' for practical use, but more to demonstrate the concept of a vapour-generating pre-heat stage to generate a high-power alcohol burner. I hope no-one in their right mind would actually try to use a burner like this…
All that faffing with a syringe and filling the pre-heat burner adds to the effective time to boil…
May 7, 2010 at 9:12 pm #1607655So, any "craftsman" types want to take a crack at making this into a practical stove? Or maybe we should just send the video link to Tinny at MBD?

May 7, 2010 at 9:47 pm #1607671Tinny use to have a stove called the SST. It was pressurized, and had a thumb screw in it. One thumb screw was to cover the opening where the alcohol went, but that same thumbscrew was directly in the path of the flame, which would transfer the heat back down into the alcohol reserves, super heating it. The thing ROARed, but was very unstable. The stove aluminum would bubble, deform, connections would warp/melt. He eventually stopped selling it for those reasons. But the performance was about the same as I see in the stove above
Here you go Jim.
May 8, 2010 at 5:45 pm #1607866> Got something in mind, Roger?
No, nothing right now. But it was filed away …
Cheers
