I was thinking about those glass propane patio heaters the other day (tower of flame shooting up a glass cylinder or pyramid), and was wondering if a similar setup could replace the (upper part of the) riser on a rocket stove. You obviously wouldn't want it running as hot as a typical rocket stove (maybe a large excess of secondary/tertiary air, maybe even a setup where the gases from the combustion chamber are actually sheathed in the added air?), any other design considerations that come to mind? I know this wouldn't be running at top efficiency, but that's not always why we do things . . .
