(introduction...)
The intent of the previous chapters was it to demonstrate that it is possible to build a cost-effective and reliable gasifier for charcoal. The basic conditions for a practical application of gasifier-engine-systems in the power range 2 - 10 kW seem to be fulfilled. What else can go wrong? Some comments to nontechnical problems, typical for situations in rural areas of developing countries, may be useful to remind of the complexity of technical co-operation.
