I have finally cracked the nut on an alcohol stove that I actually like! The penny stove (http://www.csun.edu/~mjurey/waite_instruct.html) has consistently boiled 24 oz of water on 1 oz of fuel with lots of left over burn using an MSR titan kettle. I have found the 16 oz constraint that most stoves seem to have frustrating to say the least... considering that I'm a bit of a tea addict morning and evening.

What really got me going was that it boiled (and I mean a solid rolling boil with pleny of burn left) 2 full quarts on 2 oz.

Fuel used: 50/50 blend of standard s-l-x denatured and 91% isopropyl alchy. I'm also sold on this blend if for no other reason than you can see the flames.

Water temps +/- 45 degrees.

Air temps - mid50's

I modified the stove by drilling the jets in the center ring of the burner to concentrate the flame under the center of the pot... so far so good...

I "geeked out" on DIY alcohol stoves and built probably 50 over 2 years.

The Penny performs well but in my tests it only beat an openjet Pepsi can stove by 30-35 seconds. I also played with burner location on several of these.

I ended up using JB Weld to get a perfect seal.

I consider the Penny to be among the easiest of these stoves to build so first timers would do well to start with one.

In field use I find it tricker to light than an openjet design, even with a primer pan.
