This is my wood fired dune buggy. There is a large fire box with a large dc powered centrifugal fan blowing air into the bottom of it so that the ashes and coals are burned and blown up the smoke stack. The boiler itself is of Field Tube style. that is not apparent looking at all of the insulation and sheet metal. The largest diameter tube is a schedule 40 2 1/2″ pipe about 6′ tall with fins welded onto it and wrapped with a 1/2″ black iron helical coil. The engine is a 2x2x2 Vee by Strath Steam out of Australia. I abused it a great deal and it was not damaged. Drive is by notched belt to a VW bell housing and transmission and clutch. Note the condenser on top of the roof. This is the vehicle that flunked the safety inspection at Burning Man and that is a very sensitive subject to this day.
Strath 2x2x2 Engine All Apart
These are all of the parts for a very well designed and made small steam engine. The over-hung crank has another part on the front of it so there is a shaft coming out of the front of the engine for auxiliary power. In this case it drives the water pump and alternator. This engine has piston valves and they are quite efficient. As much of the engine as possible was made from castings that were then CNC machined.
