Architecture students at Westsächsische Hochschule Zwickau have developed an energy-efficient and visually appealing prototype of a “chameleon wall”. The facade changes its transparency and colour intensity depending on the temperature. Its colours shine particularly brightly in summer.
It looks like a refrigerator, but is actually an incredibly efficient energy provider: Ceramic Fuel Cells GmbH’s BlueGEN generator is based on fuel-cell technology and can deliver approximately 13,000 kilowatt hours of low-emission electricity a year.
NEW LIGHTING MATERIAL
Chemists at LMU Munich have created new environmentally friendly compounds based on silicon and nitrogen. These nitridosilicates can be processed into coating material for LED lamps that makes them emit a warm-white glow rather than cold LED light.
The Solarte product range of the Nuremberg-based Belectric company does not only use sunlight to produce electricity, but also looks good too. The specialists in organic photovoltaics are using solar cells as green wall cladding with interesting designs.
