The Simple Survival Earthship is designed to provide comfortable shelter, clean water, contained sewage and basic solar power for lights and charging small electronics at a very low price. This building uses simple systems developed for the earthquake-relief demonstration project in Haiti. The Simple Survival Earthship may be built with one or more rooms and has evolved to include Vaulted Concrete and Wood Roof options. The concept has been applied to numerous disaster-relief and humanitarian builds around the world.
