Micro-gasification: Cooking with gas from dry biomass A word of thanks This manual was initiated and supported by Dr. Marlis Kees, the manager of the sector programme for poverty-oriented basic energy services HERA, implemented by the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH. Without her and the entire HERA-team this resource on micro-gasifiers would not exist. All text unless otherwise marked or quoted was written by Christa Roth, with contributions and technical review by Paul Anderson, PhD and Hugh McLaughlin, PhD, PE, who kindly allowed me to quote from their texts without marking a passage as a quote. In that sense they can be seen as co-authors of Module 1. Kelpie Wilson (International Biochar Initiative) contributed the ‗bonus-track‘ on Biochar, found in the Annex. For the assistance in reviewing and giving helpful suggestions for improvements thanks go to Dr. Agnes Klingshirn, Gregor Kraft (BauerPauer), Kevin Mortimer, Nathaniel Mulcahy (WorldStove), Crispin Pemberton-Piggott (Newdawnengineering), Dr. André Seidel and Paal Wendelbo. Dr. Christoph Messinger and Stefanie Röder assisted me with their abilities to structure content and make text readable. They did a lot of work that would otherwise be the job of an editor. Thanks also go to Johanna Hartmann and Sabrina Cali for the efforts on sorting out some formatting issues, especially of the countless tables of Module 2. Unless another source is stated, all photos were taken by Christa Roth.

This first edition should still be considered as ‗work-in-progress‘. Regular updates are envisaged to incorporate the changes in this dynamic field of micro-gasification.
