Tech companies are working hard at developing the next sustainable and energy efficient device in the most creative of ways. Sony has done it’s share with the bio battery and wind-up/spinning cameras.
One of the popular concepts being played with are solar-power backpacks because of their portable charging feature. Blue line, a Chinese company, focused on this popular theme at the 2008 CES show by attaching a solar panel to a person’s back. Unfortunately, that’s it for the design. The body harness is a bit clunky for my taste…there are better alternatives already out there like the bags from Voltaic.
