See the Composting Toilet Systems Book and Humanure > Handbook for more information. Composting toilets actually have a bit of trouble dealing with urine, especially the small self contained units. Too much liquid drowns them and makes them go anerobic instead of aerobic. This is why most of them have electric heaters in them... the non heated ones that only have a vent fan to aid in evaporation can handle a much lower loading than the ones with heaters. Now.. there is no reason that you couldn't use a solar thermal system to aid in the heating and evaporation instead of an electric heater... but I know that too much liquid can be a problem. I still think that a bidet would be good to avoid using so much paper. In africa I used a little tea pot of water, and it was fine. For my current situation, in the winter the outhouse is well below freezing most of the time, so it might get a bit frozen up..... but perhaps I could think of a way to incorporate a solar thermal system on there too...
