Michael Reynolds is known for building net zero green buildings. He calls these buildings “Earthships.” His largest project at this time is this building he has constructed in Argentina. This structure is very different from his most common designs. He has traditionally built homes around New Mexico and Arizona, but instead this is actually a school. Each building is made from 100% sustainable material and a solar power energy source. Inside of many of the exterior wall of this building are glass bottles. This not only turns trash into a material, but also generates natural light to the house, much like traditional stained glass. He also uses used tires to create a retaining wall and many of the supports for the building. Lastly, he used many aluminum (soda) cans along with mortar to create many of the pillars the school contains for both aesthetic and structural quality. This is the first sustainable school in Argentina.
