German Designer Gets the Ball Rolling For Sustainable Energy
André Broessel, of a company called Rawlemon, says the new solar energy harvesting system is 35 percent more efficient than conventional dual-axis photovoltaic designs. The design has won Rawlemon a nomination in the World Technology Network Award 2013’s shortlist. He’s also produced a version called Betaray which can capture and concentrate sunlight even on cloudy days.
Instead of silicon cells, the sphere is filled with a transparent liquid. One of the advantages of the Rawlemon design is its spherical, transparent shape which combines a concentrator lens and emitter.
The system incorporates a rotational weatherproof natural optical tracking device that makes it suitable for any surface. A modular collector system enables it to charge and store energy day and night and it can be expanded with a Stirling engine to generate surplus electricity.
Like all new technologies, it needs to be tried and tested but it adds diversity to solar power technologies, besides offering a great design that would add aesthetic value to any building.
