Both the video and the pictures are very clear, and I'm amazed by how efficient your stove obviously is; it looks a cracking compact bit of kit!
I spent an hour or so earlier on to see if I could find an explanation as to how this works and the principle behind it, but with no success; I'll have to search further and see if I can find an explanation of the science of the thing. I'm the sort of person who learns best from a written explanation of the principles involved with perhaps a diagram; there are loads for the twin-wall design but none that I can find for your design.
Thanks a lot for taking the time to do this, I love to learn new stuff and this has been an eye-opener for me
Back to the searching, then!
