Working with fellow National Geographic Explorer Dr. Luke Dollar, Chair of the Center for the Environment and Catawba College’s Department of Environment and Sustainability and his students, T.H. and Enas Culhane built a “twin dragon” Solar CITIES IBC tank digester system with floating IBC tank gas holder inside the greenhouse on campus. The system has 100 feet of pex coil in each tank connected to a propane gas water heater that circulates hot water in the system. Eventually the water heater will be switched to run on biogas.
