John here.To live in an ecologically minded, sustainable way, as much thought has to go into your consumables after they've been consumed, as went into their preparation. Let's be clear here: I'm talking about excrement. The fact that the topic is shied away from in polite culture is part of the problem with how we deal with it, or rather, don't deal with it. We simply flush it down toilets with perfectly good drinking water and send it to a central location to be treated, along with everyone else's leftovers, by an array of organisms and chemicals, out of sight and out of mind. There are plenty of problems with our waste management practices, which don't need to be delved into right here. Let it be enough to say that we have decided, for various reasons, to seek an alternate, and more direct method to manage our byproducts.
Introducing: the composting toilet.
This is usually the part where someone, enviously listening to our plans and dreams, starts to furrow their brow and mentally take a step or two back. Granted, crapping into a bucket sounds like a great place to draw the line between environmentally-minded home builders and back-woods-creating-a-bunker-for-the-up-coming-apocalypse nutsos. The truth is, modern composting toilets (and even some well designed buckets) are truly eloquent, ingenious solutions to a wide-spread problem. Ours arrived a couple days ago.
It's a Sun Mar Excel AC/DC. It has a high enough capacity to handle the two of us and guests full time, and will eventually be the permanent (and only) toilet in our house. The finished compost has no smell, looks like really nice soil and can be used to fertilize flowers and trees. The unit pulls a small amount of electricity to run a fan and heating unit, and can run on direct current in a privy until the house is built.

We built the privy earlier out of someone's deconstructed deck, three different houses' siding scraps, some corrugated tin and, for a touch of true class, someone else's left over bamboo flooring. Earthwise again. It's situated between the Yome and the future site of our shop, shaded by some green alders, and lit at night with a battery-powered LED. We were pretty excited to bring the toilet out and hook it up.
As it turns out, we were unprepared. Really unprepared. A 12 volt fan, I've since learned, will not run off of a 12 volt battery. To run the fan enough for aerobic composting (the kind that doesn't smell), we actually need a deep cycle battery and a 10 volt solar panel, neither of which we brought with us or had a source for in Kingston. We decided to set up everything else in the meantime, and quickly found that we had left our battery powered drill in Seattle and had no way of installing the vent. We sat under the maple, had a glass of whiskey and left.
