The woodmobile
Who needs gasoline or batteries? John Dutch’s Volvo 240 is powered by wood.
“After 2000 kilometers on woodgas everything worked properly. Top speed is 120 km/h. Cruising speed 100-110 km/h. Fuel consumption approximately 30 kilos of wood for one hundred kilometers, which is also one effective filling of the fuel bin. The back seat loaded with sacks of wood make the total range approximately 400 kilometers.”
