Rolf Disch has designed a new house with a solar-collecting arrayon top that follows the Sun all day long, but the real feat ofengineering comes from the structure itself. The entire house rotateson a central axle. The front of the house is composed of triple-glazedglass to point toward that glowing ball of gas in the sky during thewinter, while a heavily insulated backside rotates around to keep theheat at bay during those warm summer months. And that balcony you seeat the top? That isn't a simple railing system; those are solar vacuumtubes for heating water and moving it throughout the house. This houseis so energy efficient it actually generates more energy than it needs.And I thought the five-star energy rating for my new home was a bigdeal. More pictures after the jump.
