I'm finally back from Port Aransas! I loved the beach, but its great to be back home. I missed my friends and mainly, my dog. A six hour drive back home with my brothers was enough to make me want to walk all the way.
Recycled materials: Much of the materials used to build Earthships are recycled. For starters, the structure is built with used tires filled with dirt. There are tire dumps like the one pictured here in every country in the world. There are even places that will pay you by the tire to take them away. The walls (above the tires) are created by placing plastic and glass bottles in concrete.
