A spherical glass solar energy generator, which even has potential to harvest lunar energy for producing electricity is center of attraction these days. This innovation by Barcelona-based German Architect André Broessel is called ß.torics system. This device looks like a giant transparent marble, has a fully rotational weatherproof device with ability to track sun, concentrates sunlight or moonlight up to 10000 times. The ball lens and specific geometrical structure is 35% more efficient than existing photo-voltaic designs.
"Design for a social world - Let's create energy where we use it - in our cities" says the slogan at André's site Rawlemon. They also claim exceptional module transparency and highest diffuse light ratio compared with other optical systems:
Rawlemon's ultratransmission Ball lens concept of optical tracking with low-cost industrial white glass and a refractive index of 1.53 provides a very small focal point, concentrating diffuse light.
Application of ß.torics system include embedding it as windows on the walls, while generating electricity at the same time. Imminent exhaustion of fossil fuels and need to address environmental issues requires implementation of clean and green energy. This beautiful innovation, generating electricity in a substantially efficient manner, may very well prove as a self-sustainable clean and green energy source for urban population.
