Rawlemon Spherical Solar Energy Generator

An interesting and beautiful solar energy collector:

From the Rawlemon website, “We’ve been through a long research and creative process, from early studies, concepts and sketches to 3D models, calculations and prototypes, loads of Ball lens studies, through to measuring the performance and the energy transmission values. Through these tests we reached the conclusion that the perfect shape of the ball lens not only has excellent energy transmission, but also the capability to concentrate diffuse light.”
