Great stove. I've built several for myself and for friends over the past several years. I've also tried other designs but keep finding myself using this stove. Just this past weekend, my two Photons worked great when others were having problems with their Whisperlites and Esbit stoves. They fast became "crew" gear.
Great, you timed the boil AND let the 1 oz fuel run it's course and timed that. That allows you to calculate how much fuel was used and thus the efficiency. 1 oz (240 sec/370 sec)= .65 ounces (45% efficient) Typical usage is 1/2 ounce for ~60F water which is about 59% efficient, so your water may have been colder than 60 F, the pot you used is much more massive than a Heiny pot and required more heat to elevate that, or your massive garage floor was cold and acted as a merciless heat sink.)
Made a photon stove yesterday. Fired it up today using one ounce of alcohol. Brought a pan of ICE to a boil in under 5 minutes. The kicker? It's -5 degrees here today with a -15 degree windchill. No way a penny stove is going to do that and nothing wrong with thermal transfer either. For just boiling water it's hard to beat. Don Johnston has now devised a simmer ring for the stove as well but for cozy or FBC cooking it's not needed.
hey there cool stove but I just finished building a foster's alcohol can stove that is preheated and ready with room temp fuel and it holds 1 cup of fuel wich burn close to 1 hour.
Do you know where the idea for the penny stove came from? From the photon stove. The only difference is the penny stove replaces the screw with a penny. I prefer the screw as its harder to lose. If I do lose it though I can always substitute a penny
It boils two cups of cold water reliablily in almost any conditions with one ounce of alcohol. Seems pretty effecient to me.
Preheat is a simple process and is required with the photon style design. The bad thing is the need the primer pan. The good thing is they burn hot and cook fast.
I heard some crackling early on, but otherwise its silent. Sorry
Your not used to how white gas stoves burn are you? Large flare ups until they come up to temp. Really this isnt much different as its only flaring up until it gets to full operating temp

How many holes do you have in the burner part, there is so much flame. I built mine and had alot of holes in mine.

mine has 24 holes made with a sewing needle. I have built ones with fewer and they boil slower but still while burning the same quantity of alcohol.
In my experiments, the more small holes you have the faster it will burn fuel and reach a boil

Build the penny alcohol stove, it kicks ass compared to any other design.

Flame is too loud!
It is not good to need preheat.
Thermal efficiency will be poor. JSB
