An Earthship, in case you’ve never heard of it, is a kind of house made from natural and upcycled materials – like, say, empty beer and soda cans. In fact, that’s what the very first Earthship was made from, which is rather astounding, when you see just how spiffy it looked (middle image). That original Earthship was built in Taos, New Mexico in 1971, and we can thank visionary architect Michael Reynolds for its existence. The Earthship community is still going strong, and building zero-waste, passive solar homes in over 20 countries around the world. Aesthetically speaking, the houses are wildly varied, and should you care to see more, you might like to take a peek at this article on the topic from Altas Obscura, or pop over to the official Earthship website.
