As some basic instructions on how to build an Elsa stove have been given at my previous post The birth of a biochar stove, now I would like just to share some insight about a very practical modification that can be applied on an already built stove or implemented during the construction of a new stove from the beginning.
It's about finding a good point where to cut the stove in two pieces... and extend it properly in order to load more biomass and so having flames that last longer.
At the moment it's just the beginning of some new experiments but I definitely think that having sets of cans exactly with the same sizes and repeating the same joining procedures... you could extend your stove at the desired height. There must be a limit but it would be very nice to discover it empirically try to add more and more extensions to see what happens.
Well, still on the search for other cans with the same sizes, I will have to test some other solutions and see how it goes. Keep checking out the next posts...
