It may look like something out of a futuristic novel, but its the newest solar energy generator that can fuel clean energy to thousands of homes much better than solar panels.


It’s a completely round sun tracking globe – essentially a giant glass marble nuzzled into a computerized metal frame.

But this lovely clear marble captures the light of both the moon and the sun – and does it better than solar panels,… 10,000 times better; making the solar harvesting capabilities of this device 35 percent more efficient than conventional solar panel designs. 

The Science 

For the last 40 years we have tried to capture this energy with PV panels, but the earth is moving around the sun, and the fixed panel is losing its efficiency.” 

Andre Broessel’s invention may be more than just a giant marble, the German architect increased his orb-like system by combining it with a computer program which tracks the sun.

How It Works

The rotating glass orb brings in energy from the sun and concentrates it onto a small surface of tiny solar panels.

The ball lens concentrates and diffuses the light into one small focal point.

Stanford University’s associate director on energy and sustainable development Mark Thurber told the Wall Street Journal back in April, the most intriguing renewable energy technologies are those that have the most room to improve. In terms of solar, he said at the time, perhaps concentrating solar power can make significant strides as we learn from the first large installations.

The Future Of This Technology

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.

Broessel’s device is not yet available in the market. Overshooting the initial Rawlemon Solar Devices indigogo campaign of $120,000, the campaign has now exceeded $231,000.  The money is earmarked for further testing and for patent applications he’s filed in five jurisdictions.
