German Designer Gets the Ball Rolling For Sustainable Energy
AndrÃ© 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 2013âs shortlist. Heâs 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 âoffering âa great design that would add aesthetic value to any building.
