In this age of high fuel prices and concern with continuing availability of oil, scientists are working on a number of approaches to alternate fuel sources. These concerns may provoke interest in how some people in gas-starved Europe dealt with such problems throughout the war years, 1939-1945. One of the most successful innovations, were the so-called "gas producer" vehicles that utilized the by-products of solid fuel combustion, employing such solids as coal, charcoal, turf, and wood to produce fuel gas for a standard internal combustion engine. This book provides an overview of such vehicles, including those used by the Wehrmacht. Schematics of operating systems and the regulations concerning their use are also included, along with a translated German illustratedoperators manual.
