I bought a new can of fuel for my butane stove (posted previously):

I bought a can of Ronson Isobutane at Home Depot. It lists the contents as Isobutane CAS #75-28-5 and lists contents as 5.82 oz or 165 grams. It costs $2.99. I weighed the can without the cap and it weighs 7.5 oz or 213 grams. With cap it weighs 7.6 oz or 217 grams.
I understand that standard butane canisters designed for backpacking stoves include some propane since butane does not vaporize well near or below 32F or 0C. I can also see that the canisters are much larger in diameter which makes them more stable and may help fuel vaporize better due to less exterior surface area (not sure on that one). They also have threaded nipples so interfacing to a stove is much more secure and easier to build.
I am wondering, however, if the butane can may be a better base for a lightweight stove (as long as cold weather performance is not an issue). The cans are made of aluminum (used cans can be recycled into alcohol stoves
). The gas canisters appear to be a light steel (a bit heavier). Also, the Ronson cans are available in many places where cigarette (and lighters) are sold like drug stores and convenience stores. The canisters need a camping or sporting goods store. I can easily find 70gram and 165gram cans and they both work with my stove.

I see someone in Japan has tried this:

Anyone else considered trying to build this can into a stove design?
