3D model of a wood gasification system connected to an IC motor. The gasification system creates wood gas from wood chips, tree branches or logs and uses this gas to run an internal combustion engine on. The system was inspired on the Planet Mechanics system designed by Strawbridge/Stansfield. It was improved to a large extent though, by replacing the original radiator for cooling with 2 oil tanks circulating the heated/cooled down oil. An Alpha-type stirling motor is added to also immediatelly generate electricity; making it a hybrid system, immediatelly improving efficiency by 40% (making it 70% efficient; IC-engine is 30% efficient). The cold pistons of the stirling motor are cooled by circulating water. The electricity generated can be returned to the net (via net metering). Further improvements are:

* a better sealing by using a hermetically sealable hatch
* a better wood (and charcoal) stirring; this is accomplished by 2 whisks for stirring the wood, and a rotatable grate movable by metal wires, pulled on by a seperate electric motor (so that both stirrers do not need to be used at the same time). The top grate can be taken off from the lower grate, so as to allow easy cleaning.
