I just saw this brilliant development by designer Hyun-Joong Kim & Kwang-Seok Jeong, created to gather and redirect solar energy used to charge your iPods, phones and other tiny gadgets. The lenses of these Self Energy Converting Sunglasses have dye solar cells, collecting energy and making it possible to feed power through the power jack at the back of the frame. “Infinite Energy: SIG”
The dye solar cell is described by the designers of the SIG as “cheap organic dye [used with] nano technology [providing] “cheap but high energy efficiency”. Inexpensive, light, and visible-ray penetrable. The lens turns sunlight rays, (rays that would otherwise harm the eye,) into electrical energy.
