Concentrar la energía del sol.

spherical glass solar energy generator by andre rawlemon

german born, barcelona-based architect andré broessel has sent us images of his latest development of a spherical glass

solar energy generator. the project uses the advantageous strategy of implementing a ball lens and specific geometrical
structure to improve energy efficiency by 35%. in contrast to its traditional photo-voltaic 'dual-axis' counterparts,
the device incorporates a fully rotational weatherproof natural optical tracking device that is adequate for functioning
on inclined surfaces and curtain walls, empowering any building surface. the new solar generating concept has
capabilities that concentrate diffused daylight or moonlight for a more effective site context application.
