Could A Glass Sphere Revolutionize Solar Power?

WORLDCRUNCH (2014-02-27) A German-Spanish startup has created technology it says is so effective turning light into energy that it can also utilize moonbeams and office building windows. Looking into a glass ball has always meant looking into the future, speculating, daring to be visionary. But André Brössel, the German-born head of a Barcelona-based start-up called Rawlemon, has given the term a whole other meaning.  His firm has developed futuristic solar collectors — collectors that look very different from the usual installations. They are not flat, right-angled panels, but spheres. The role of the glass balls turns out to be much the same as that of classic collectors: to turn light into electrical current. Like large lenses, the transparent liquid-filled glass spheres collect rays of light. Depending on the diameter of the sphere, fire point increases up to 20,000 times. Photovoltaic cells and heat-driven mini-generators transform the energy into current. The light concentration resulting from this principle is so effective that Rawlemon’s collectors don’t only work when the sun is shining, but when it’s cloudy and even at night. Yes, after sundown, the balls can even gather moonlight and transform it into electrical energy.
