i made and tested my first alcohol stove yesterday, as per instructions i found here:

http://www.jureystudio.com/pennystove/stoveinstruct.html

so far im very impressed with the performance of the stove, and kind of disappointed that i hadnt heard of it sooner. For most of my camping life, ive tried to come up with some alternative to 1lb propane tanks and stoves, some have been coffee can wood stoves like the penny wood stove on that same site, but lately ive been using sterno, which doesnt perform that well for the weight.

the question i have now, is there a limit to the effective size of the stove? the one i made, as well as the ones ive seen online, are about 1.5" tall. can they be made taller to hold more fuel and burn longer?
