Nowadays, I am more interested in making my own copy of a wood fire stove to prevent any impact on nature similar to this stove:

Exactly.
I use something very similar to the Churchill river stove, but a much simpler (and cheaper!) design. Essentially just a bunch of steel plates hinged together with wire (the simplest possible hinge: Make a hole, thread a wire, twist). It gets the work done.
