Keeping our myriad electronics charged while traveling can be a constant challenge. But the very clever folks at the Brooklyn-based design firm PENSA have come up with a brilliant concept to keep us all topped-up while on the move.

Aptly called Street Charge , the concept is to attach a light weight structure to existing street signs or poles and to power it with photovoltaics and batteries. Users simply plug-in their electronic gadgets and wait for enough charge to make calls, text or surf the interwebs.
