Cool, how do you do that? It is certainly easier to do in an armchair. What 
about the residual tar content with even the best gasifiers? Then there is the 
water and dissolved organics which will acidify the engine oil and eat up the 
bearings? 
An interesting thought is that the tar content of the gas is somewhat 
dependent upon the efficiency of the combustion process within the gasifier. Complete 
combustion of the solid fuel results in zero tars-right? However, this is not 
gasification, but combustion. Gasification is a step toward combustion, being 
  between complete combustion and mere whatever else say pyrolysis.
