-The system itself is pretty simple: A very small 4-stroke gas engine with 25ccm and about 0.7kW/1HP output power drives a brushless motor that is acting as a generator and converts mechanical energy from the motor's shaft into electricity by rotating strong neodymium magnets around coils. At the time being the APU will be fueled with gasoline but the final goal should be a complete conversion to a mini wood-gas block cogeneration plant, combusting biogas to get 350W peak power output and warm water as well. And of course, it's a nice hacking platform for 4-stroke engine designs, to see which fuel solutions might also be usable.
