“Hi Ryan
1- I like the concept of this simple stove system like Jetboil.
I ordered several Beer can stove systems through this site. for me and my friends.
However,,, I can not find 750ml Beer can in Japan !
Would you sell 750ml Beer cans ?
2 – And why will not anyone make kinda universal heat sink atachment like Frux ring as used in Jetboil ?
Maybe it will be effective for low output stove system like this.”

Konnichi wa Hajime-san. Watakushi wa Biru desu. Doozo yoroshiku.
1- Your first question about a 750ml Beer Can. Since this is an Australian Beer have you thought about contacting the Australian Embassy and asking them if they know of a place in Japan where you could buy Fosters Beer in the 25oz size. If NO, next ask if any of their staff ever gets it sent to them or ever bring it back from Australia. I would explain why you are asking and that you are looking for a few empty cans for a backpacking cook pot. Maybe show them a picture or send them the web site showing how the empty can is being used. They might be able to help you.
I also found that the Snow Peak Titanium French Press is very close to the width of the Fosters Beer Can.

The Snow Peak item is 3.25″ wide and the Beer Can is about the same size. The Snow Peak French Press costs a lot compared to a beer can but it also can make coffee. Snow Peak also has many small cups and mugs but I can’t find a size for them.
2- When the JetBoil was first shown last year I called them and asked if they would privide or sell just the Flex Ring part to someone for research. I explained I would like to see if it could be adapted to other stoves types. They said NO. So without having seen one yet I made my own version of a Flex Ring. I really made two. The first one had Aluminum Fins with a Stainless Steel top part.






The second one had thin Brass Fins and a Titanium Top part. The Brass/Ti one was much lighter.


I wanted to see if the my Flex Ring version would work with my Brasslite alcohol stove. It didn’t.
(Added) I should have said I wanted to see if the Flex Ring would make my Brasslite Stove boil water faster – it didn’t.
The alcohol stove didn’t generate enough flame velocity to drawl the flame up and through all the fins. It did work a little but did not boil water any faster than without the Flex Ring thing. I though about adding a small computer fan to help blow the flame but the added weight didn’t seem to be worth it.
I had to decide at what point the stove got to heavy for me to carry vs other light stoves that will boil water as fast or about as fast. When I care less about weight I carry a light canister stove.
