Spherical Glass Amplifies Solar Energy Collection

ball-lens-render-building

Solar energy collection has had some vast improvements over the last few years; however these new prototypes from German-born, Barcelona-based architect André Broessel are quite striking since his concept uses a spherical glass to amplify the sun’s rays for electricity generation. Traditionally, solar energy collection becomes effective on vast scales, especially in solar farms, where panels orient themselves optimally to gather the most light possible.
