A German builder has designed a rotating solar-powered house which follows the sun's movement. The Pond 133,000 home turns on a steel circle to attract the maximum amount of sunlight at all times. Ten families are already living in the houses designed by Ernst Osswald, from Zoltingen. He's received another 50 orders this year. The Mirror quotes resident Margarette Krafeld as saying: "I recommend everyone to live this way. It is absolutely wonderful".
