Hélène Dubé and her partner Alain Neveu from Es-Cargo (http://www.es-cargo.qc.ca/) have lived off-grid in Quebec, Canada for 11 years in a self-built earthship style home made of recycled tires filled with earth and large south-facing windows. Their water is gravity fed from a spring-filled cistern placed up the hill from their home, their power comes from solar energy, and they use a composting outhouse toilet. For heat they have a homemade rocket stove that is an efficient way to burn wood, and they also use it as a cooktop in the winter.
