German architect André Broessel, of Rawlemon [1], has presented new invention which is future of renewable energy. The invention is  a spherical sun-tracking solar energy-generating globe -- essentially a giant glass marble on a robotic steel frame. This invention  concentrates both sunlight and moonlight up to 10,000 times -- making its solar harvesting capabilities 35 percent more efficient than conventional dual-axis photovoltaic designs.

The inventor was a finalist in the World Technology Network Award 2013 with the globe's design and afterward produced this latest version, called Betaray, which can concentrate diffuse light such as that from a cloudy day.
