Zack and I are sitting around right now chatting about alternative energy sources and passive solar heating. We've been discussing different ideas for heating systems that work to both heat the house and produce hot water- things like a system which works off a tiny fireplace, channels the heat and carbon through the water heater, then into an algae container to process the carbon.
I've also thought about doing a composter that takes advantage of solar heat to reach high temperatures, then passing the water through a coil inside the composter and then though the rest of the house. That way, you get hot water and heat for the house, as well as a way of processing organic waste.
