Coal and wood to gas
One of the most important technical developments in history was the discovery of gas production from dry-distillation (carbonising/pyrolysing/heating) of coal and wood.
The technology meant not only a revolution to lightening with gas and heating technology, but it was in the 1860s also the basis for the chemistry of artifical colours produced from tar liquids.

Coal and wood to gas
The discovery of combustible gas was furthermore the main driving force for the development of gas-blown combustion engines (called explosion engines at that time (imukaasumoottori)).
Nomenclature like "gas pedal" and "step on the gas" remember to this historical relation.

Coal and wood for fuel engine
Italian Garuffa built a gas generator, in which he used as fuel wood. Initially the engine power was about 12 horse power, but soon they learned to build a large and heavy for hundreds of horse power engines, began to improve relations against the steam machines.

Coal and wood to gas
Early 1920s in Finland has been made first tests with wood gas.
France and in the 1930s, including Germany, the state has actively supported the development of wood gas-using cars owned by various tax breaks.

The most significant developer of wood gas generator was Franco- German chemical engineer Georges Imbert (1884-1950).

In Sweden has been two pioneers:
Axel Svedlund
In 1920 he installed coal gasifier to his car. 1945 had prepared a total of about 35 000 Svedlunds patented coal gasifiers.
Torsten Källe
He designed the 1941 passenger cars, meaning a light carbon gasifier (Kalle-generator (Kallekaasutin)). Peculiar structure, it started much faster than others ready to produce carbon monoxide gas. Kalle-generator was highly successful in Sweden.
