During the raffle, some may have noticed a faint odor emanating from the out house, at least I think that's what it was and where it was coming from! A fact of life with a setup like that and no big deal, BUT sitting there I eyeballed the vent stack at 8", and it occurred to me I had in my shop a 8" rotary turbine vent, the kind you see on industrial buildings, the slightest breeze (jeweled bearings) starts them spinning and they create airflow, venting whatever they are hooked to in a much more positive manner then passive venting. It also turns out the campground host is the brother of an old hang gliding buddy and we had met before. Anyway, Monday morning I took the vent to the UPS store and JC will have it today, complete with mounting screws. Moving more air speeds the "process" in an outhouse, and can increase it's capacity, speed the process, and lessen the odor.
Another trick is to paint the vent stack black, and build a box around it with the front pointing south and glazed. Now, when the sun is out, you have a solar heater that starts a strong airflow in the desired direction. A last trick is an automatically controlled fan that starts when the seat is lifted that further assures proper airflow. I build a temporary setup like this years when moving onto my first property, using all these tricks, and had the user input area(toilet seat) inside the 5 th wheel trailer, basically a hi-tech inside outhouse. No hole in the ground, everything went to a ground level slab with 2' high cinderblock sides. Two years later when I built my house (I had to get the Kitfox flying first, priorities) and regular septic system, I got to see how effective the process was as I took it all apart. It worked GREAT, these are called composting toilets I believe, and with a few upgrades an older style outhouse can vastly improve it's performance. Another system utilizing a 12" PTO tractor post hole auger and a lawn chair with the bottom cut out, can be usefull for short periods, but you didn't hear that from me
