A Stylish Solar Charger for Your Gadgets

A few years ago, the company Rawlemon designed a spherical lens solar generator, which works better to capture solar energy than a regular solar panel array, and looks much better. The original Rawlemon spherical lens solar generator was created by a Barcelona designer and architect André Broessel of Beta Torics. The system basically uses a large glass ball that is filled with water to concentrate the sun’s energy onto a PV panel. In this way the suns energy is concentrated by up to 10,000 times. The ball can also be rotated and includes a tracking system, meaning that energy collection is maximized throughout the day. However, the design has some serious drawbacks, such as weight of the water-filled ball, which can’t really be supported by most roofs. Another drawback is the problem of producing the glass balls of sufficient quality and size.

A team of researchers at the University of Michigan has successfully developed a prototype of a semi-transparent photovoltaic solar cell, which they hope will make solar arrays more attractive to consumers and lead to a more widespread adoption. Existing solar panels are far from aesthetically pleasing, but this new invention could be used to cover the sides of buildings, window shades and even billboards without obscuring what lies beneath.
