I was giving a highly conservative number since it was a pretty loose method of guessing the exact temperature. But you are right.

I checked out your site. Are you saying that you burn fuel at the rate of 3.77 ml/min? At 5 minutes, your best time for two cups of water, it takes 18.87 ml.

Most decent stoves I've seen are around 59% efficient. They boil two cups with 15ml (1/2 oz). Yours is about 47% eff at best.

Are you using a heavy pot or a light Heineken can in your 2 cup tests? That could explain the discrepency. Also, is the ground beneath the stove hot? You could be bleeding off heat that way.

The numbers on the site are conservative averages to take into account margin of error, varying cooking conditions, and to make sure that I don't over promise the capabilities of the stove. I have had tests where I boiled 2 cups starting at 70 degrees Fahrenheit in 3:30 min with 15 ml of denatured alcohol, some test went up as high as 5:30 minutes to boil 2 cups, and used 20 ml.

However the most consistent average 2 cup boil time is about 4:20 minutes, using 20 ml of denatured alcohol which burns for a total of 5:50 min.

The type of pot varied for different testing phases. The 3:30 results were obtained with a heineken type pot. The rest were either a heavy gauge aluminum tin, or Steel Pot. The ground was not hot in any of the tests. I hope that helps satisfy some curiosity.

Sorry I meant "the most consistent average 2 cup boil time is about 4:30 minutes" not 4:20. Typo.

I don't think they are making this stove anymore, they site only shows 2 pop can stoves and 2 cook kits for sale.

@bolgrats Most are.

[Jhfgsjdcd]

The heat is about 500 degrees blowtorches are 1000 degrees retards

Buy!? Looks like a can alcohol burner with a pot stand made out of washers, nuts and bent wire to me...

site now redirects to site that lacks this stove :-(

[ArmaHighVoltage]

Nice :)

[boiledrootbeer]

Nice looking stove.

[clipsesenishi]

@ninjalrt yes except for the potstand.

[EconoChallenge]

@pastprimitive Anything under a 5 minute boil time is excellent!

whats the materials: all aluminum?..
