Cool! My son and his friends have started a project of converting an old school bus into a rolling house, and were asking me about helping them with alternative energy designs. They'd found one that set its' diesel engine up for burning vegetable oil, but were asking about hydrogen fuel, how to recycle its grey water and run the electronics. My son had already discovered the carbon filtering system for water collection. We discussed rain harvesting and I turned them on to the concept of installing wind turbines and cheap solar panels on its roof. Still working on the grey water recycling theme if anyone has any info on that, please...
