Micro-Gasification Masterpiece Publication Out

There is a new publication out on all aspects of micro-gasification stoves, a more general name for gasfiers such as TLUDs, which have seen tremendous improvements over the last few years. Christa Roth is the author, GTZ (now GIZ) has published it, and it is really a 96 page work of art! It covers many of the commercially available stoves, and a few less familiar ones, in great detail and with lots of relevant hyperlinks - and prototype stoves that have not yet reached production are discussed as well. Even some do it yourself stoves are touched on - these may be problematic for long term use, because the plain carbon steels in found materials (obtanium) don't last long enough, but they are very useful for development and educational purposes.
