During the Academy classes students learn about the history and evolution of Earthship designs and systems. The guided tours offer a chance to experience different types of Earthships first-hand. From modest, owner-built to high-end custom Earthships, students learn to identify the different structures, choices of finishes and systems evolutions. Several long-time Earthship residents open their homes to Academy students. Many students are inspired by the tours and start designing their own Earthship dream homes.
