The Solar Ski Helmet is a product from Fraunhofer IZM. The company has developed a 3D solar panel that fits along the curved surface of a ski helmet. It allows the helmet to be powered by the sun, which can then power your gadgets. By placing the panel atop the skier's head, the most amount of energy is channeled to rejuvenate everything from smartphones to music devices.
The largest challenge faced with this product was creating a slim 3D solar panel that would work with a ski helmet without becoming hazardous or aerodynamically containing. Hard work prevailed, but there is no word yet on the release date of this device. The retail pricing for the solar ski helmet is said to begin at about 300 euros.
