By talented design team Sabine Müller and Andreas Quednau, based in Solitude palace gardens near Stuttgart in Germany. The installation features a 1 km garden hose arranged into countless loops, which forms the surface of a screen that catches the rays of the sun, thus heating the water in the hose. An uber cool eco-friendly solution!
