Good box stove design ideas for coal

Here is a box stove design that has some really nice features that could be applicable to building a similarly styled coal box stove. This guy has done some thinking and really nice work. I wish someone could translate it into English.

Obviously, some of the ideas might only work for wood, but I see several things that could make for a nice coal box stove design, especially if KingCoal’s base heater design could be worked in as well.
