German architect André Broessel, of Rawlemon, has looked into his crystal ball and seen the future of
renewable energy. In this case it’s a spherical sun-tracking solar energy-generating globe — essentially a giant glass marble on a robotic steel frame. But this marble is no toy. It 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.
André Broessel 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.
André Broessel’s latest invention looks like something out of a superhero movie. The bifrost device depicted in Thor, perhaps, or Eric Selvig’s wormhole machine in The Avengers.
In reality, though, it’s a stand-alone solar energy generator. And if nothing else, it’s much more interesting to look at than your standard photovoltaic solar panel.
But Broessel’s invention may be more than just aesthetically pleasing. According to a recent report in Fast Company, the German architect touts his orb-like system as being 35 percent more efficient than a standard panel, doing even better when combined with a tool for tracking the sun.
“For the last 40 years we have tried to capture this energy with PV panels,” Broessel says in the promotional video on his Indiegogo campaign for his company, Rawlemon. “But the earth is moving around the sun, and the fixed panel is losing its efficiency.”
The rotating glass orb, he says, brings in energy from the sun and concentrates it onto a small surface of tiny solar panels. The ball lens is able to concentrate and diffuse light on one small focal point, making it more sustainable (less material used to create solar cells, most of which are made from crystalline silicon) and more efficient. Additionally, Broessel says poor weather would not impact the device, because of a built-in weather tracking system.
