sometimes (but not always!) the pretension is to make the small daily most important things work better... or at least it looks like. In this case the design is made by Claesson Koivisto Rune.
But some questions aren't avoidable: is it made available for the people...? Are we in front of an open source design? What will be the social cost of this alien design? Wouldn't it be better to invest in promoting other sustainable fuel sources instead of reinforcing the unsustainable use of charcoal and wood?
The diversity of this kind of devices is enormous... all them with a long tradition.
(see for example the Kenia ceramic jiko)...
