Check out this fascinating BBC article on how a group of Serbian students from the University of Belgrade developed the first public solar-powered mobile charger.
It's truly an innovative concept and this short video demonstrates how it works.
As you can see below, the solar panels are the only source of energy. Since the equipment is public property anyone who needs to charge their phone can do so by connecting it to one of the 16 power chords.

| The chords used to charge cell phones. Each side has 4 chords for a total of 16. |
The tower has had almost 20,000 charges to date and there is enough energy to sustain a month of demand if the sun disappears.
Bright ideas that use bright energy: what a concept! The group of students won the European Energy Award for their work making them the youngest group to win the prestigious award.
