Today's Dig This spotlights Earthship Biotecture,which has two websites with virtually the same information, laid out different ways. It's just one of the many quirks of the Taos, N.M.-based organization, which makes cool eco-houses and is located a mere seven hours from Roswell. I'm just saying.
The basic Earthship home prototype is made of recycled tires, packed with earth to the point of being "virtually indestructible." But they don't have to be made of tires -- in England they're made of tyres. Ha. Um, but really, each is custom made and tuned to the buyers' climate. Result? They "heat and cool themselves naturally via solar/thermal dynamics," to the point of being so energy efficient that residents don't have to pay any utility bills.
