Next challenge Street Demand provide spotlight the imaginative guys through the company Pensa. The particular essence of the challenge is to make street signs in the station for charging mobile devices. Street Charge – this is still simply a idea. Their idea is always that to the posts or even subject to any street “attach” a tiny solar panel, that will be operated from the charger to the cell phone (or more precisely, USB-outs to connect zaryadok). The thought also includes a “shelf” where you can find spot itself and the device is a cup of joe.
