Carbon negative cooking slightly oversized

Some days ago I tried to cook (successfully at the end) using the big Elsa stove that I had previously put together. Not having any adjustable frame handy I decided to hang a pot from above and just give it a try, regulating the height with the length of the rope.

Indeed it worked but... ehm... looks like I needed a much wider pot or an Elsa with a smaller mouth. That's way too powerful! Check out the short video clip at the end of the post you'll see how strong it is...
Some good percent of the flame escaped on the sides, but indeed it reached boiling in very short time (apologies for not timing it, while doing real cooking it was a bit too much). Some shots are really impressive! I had minimal to close-to-zero smoke and perfect charcoal production at the end.
Indeed it's been a very successful test... and very tasty pumpkin soup!!!
