It looks like a giant, glass marble. But this globe is no game. It’s a sun-tracking, solar energy concentrator created by Barcelona-based architects Rawlemon and, according to the designers, is able to collect not just sunlight but moonlight as well.
The weatherproof sphere is designed to rotate and follow the sun across the sky. It’s so sensitive to light that at night, it can even harvest moonlight and convert it into electricity.
Andre Rawlemon, the architect and designer, says his spherical, sun-tracking glass globe is able to concentrate sunlight and moonlight up to 10,000 times and that the system is 35 percent more efficient than photovoltaic designs that track the sun. One of Rawlemon’s idea is to build these globes into the exterior walls of buildings and use them to generate electricity. For other uses and beautiful images of the globes, click here.
