When he applied his passion to find alternatives, he looked into the sun. Helitrope house produced is a powerful concept that uses incredible energy thanks to solar for kinetic design. Mounted on a pole, the house is a time to rotate 180 degrees during the day, following the sun song. The 6.6 kWH solar panels on top to produce more than enough energy to make a positive net energy homes. A unique hand railing system on the roof of the tube serves as a solar hot water heating homes and radiators. See, in the sky – bird, that plane, that’s kind of flowers! The idea of the Architect Ralph Disch, solar home this was the seed for the rotating Diesel Development Sonnenschiff extraordinary and modern solar movement in Germany. home takes full advantage of the sun by rotating with it, so the daytime program despite the triple-pane windows and large energy roof-mounted solar array and solar hot pipe. The result is one of the first modern house in the world of zero-energy – which really ended by producing five times the energy consumed.
