Swings: Those swings are pretty weird. For one afternoon I could believe it was wind at just the right angle/frequency, but long term?
Toilets:
I'm interested in permaculture and have spent some time on (kind of) self-sufficient farms, and learned about toilets there.
Shit only really stinks if it breaks down anaerobically. Hence mixing shit and water/piss is bad. Piss in one place (err, the bushes, usually
) and shit in a special bin with a carbon rich sprinkle (sawdust, mulch, grass clippings) on top, and it breaks down wonderfully with only a mild smell. After a few months it can be composted or fed to worms, and the end product is ideal fertilizer.
