It has an incinerating toilet. It collects rainwater, but also uses anything from a faucet or stream, etc. It has a system to sanitize the water, and another filter at the faucet.
It's kind of a neat little system, since the windmill will generate power at night even when the solar
is not. Apparently it doesn't come on a trailer, but has little wheels for moving around and adjusting. They are building a trailer this year to make it a towable item.
I didn't realize it had been posted before, sorry!
