After an experiment inside a small insulated wheely bin (practical for loading and unloading..) this is a second experiment with a chest freezer, to have a well done insulation and a more "square" mass of compost so it keeps itself warm easier than a thin bin.
It goes up to 44C° inside (Edit : 49 C° the day after, with more aeration) After few days, a well done aerobic compost can even go up to 70C° !
The challenge here is to get this heat for the longer time possible, in the smaller possible container so it can fit inside a small flat or house, and doesn't need more complicated heat exchanging piping that is otherwised needed when the device is outside.
 I used here water diped freshly cut grass, to push out the bugs. Otherwise a good bunch of them tries to escape in the bathroom where i put the "stove", with nowhere to go..
I used the already made bottom hole in the freezed to connect a pipe to push air inside with a aquarium pump with a timer.
The next step is to make a evacuation pipe for the gases to go out the room via the bathroom chemney, like i did whith the wheely bin model, the pipe acting as a radiator and an condensator for the water to go back into the system so it can't dry.
Tell me if you've got some ideas for improvements.
