I don't think so... he has a solar panel for power, I forget what he does for gas/heat, and I believe he has a holding tank for water that can get cycled into the sink. The toilet is a composting one. That about does it for my knowledge of the specs. Again, for more detailed information you're best served by contacting Dave directly to talk about it. I'm sure he'd be happy to share what he's learned and talk about how he's created it along the way.
