I also just started to use an alky stove this past month. I wanted something lighter than my cannister when its just me using it.
I went ahead and made a few gram weenie stoves, using aluminum squirt bottles that I found at the dollar store. I went thru three, one that I crushed/deformed putting the top into the bottom, and two more working out the holes to fit my Soloist pot. With a double row of holes, the flame blossom was too large! Single row of holes brought it down to just about right, but I think I will build another with smaller diameter holes to shrink it even further.
After building the stoves, I read up on fuels on another thread, and bought Heet, and alcohol at the local ACE hardware. I then went to my kitchen stove top, and spent some time boiling water!
My results basically went like this; with 3 tsp, or roughly 1/2 oz. I was able to either boil or just about boil water in around 5-6 min on average. Details: with straight Heet, my burn time lengthed to almost 9 min, but I barely got the boil. With alcohol I had a rolling boil in the 5 minutes. With a mixture of Heet and 70% Isopropyl alcohol, I had a boil in a bit over 5 min.
In summary, the boils worked best with denatured alcohol, then the mixture, and finally Heet.
I live in Idaho, at about 2500 ft, and I used my well water, which is relatively cold.
The last trip into the high country, I used the alcohol, and with cold mountain water, was consistently boiling water with 1/2 oz on the little stove. I was really impressed that I could use this setup for all my cooking needs.
