Or maybe he took an old wood stove and just lined the inside with masonry or ceramic and insulation so the metal wouldnt go molten on him and used that as his firebox.
This is a batch box design built by Adiel Shnior and Shilo Kinarty in Israel. As far as I know they use custom doors for their builds.

You need to skip through the initial start, building a simple rocket cookstove and a demonstration model. Mark however, how everybody is convinced when seeing the double vortex forming.
