Have you seen this somewhere already, I wonder?! This is a new invention by a young Croat guy, a student. Very smart thing, a selfpowered bench covered with solar plates that can be used to charge four cell phones or tablets at a time, offers hotspot for internet and lights up at night. It has even more useful functions...
Those kids are on excursion, and as they are waiting for continuation of their program what else is there to do but to get some ice cream and charge your phones...
They have put those benches all over Zagreb so far, and in some cities over the world. Maybe you have seen it somewhere already?!
