The idea is for a tumber composter, turned by a Stirling engine driven by the difference in ambient temperature and the heat given off by the compost itself.
I think it would have the advantage of being self-regulating, if it were designed right, though some seasonal adjustments might be necessary.

Great idea. Endless configurations. + |

I like the idea of a self-rotating, ambiently powered composter very much. The turning time will be so slow you have lots of flexibility in power sources. |

My choice would be a tiny toy propeller, geared WAY WAY down to spin the barrel every month or so using wind power. |

Or some sort of waterwheel-esque rain catcher that rotated half a turn each time the top bucket fills? Might need a crude flap valve lid for each bucket to let water in but prevent evaporation. |

Tremendous. Now build it, ride the "lazy-but-green-at-heart" wave and make yourself rich. |

My limited understanding of compost is that it needs to be warm but not too warm; hence a Stirling which turns it when it gets too warm, thus cooling it slightly, would provide the necessary feedback mechanism. Excellent. |

What's with all these sensible ideas lately? great + |
