Tinny use to have a stove called the SST. It was pressurized, and had a thumb screw in it. One thumb screw was to cover the opening where the alcohol went, but that same thumbscrew was directly in the path of the flame, which would transfer the heat back down into the alcohol reserves, super heating it. The thing ROARed, but was very unstable. The stove aluminum would bubble, deform, connections would warp/melt. He eventually stopped selling it for those reasons. But the performance was about the same as I see in the stove above
Here you go Jim.
