Heliotrope: Rotating Solar Panel

Inhabitat: Look, up in the sky — it’s a bird, it’s a plane, it’s the Heliotrope! The brainchild of Architect Ralph Disch, this rotating solar home was the seed for the extraordinary Sonnenschiff Solar Development and the modern solar movement in Germany. The home takes full advantage of the sun by rotating with it, allowing daylight to course though its triple-pane windows and energize its large roof-mounted solar array and solar thermal pipes. The result is one of the first zero-energy modern homes in the world — one that actually ends up generating five times the energy it consumes.
