Dead battery in Belgrade? Head to the city's Obrenovac district, where a group of students has developed the world's first public charging station powered entirely by solar energy. Known as the Strawberry Tree, the structure's 16 ports support a variety of handhelds, allowing pedestrians to juice up their cell phones in just ten to 15 minutes, at no charge. Its built-in batteries can also store up to a month's worth of back-up energy, enabling the station to hum along at night, or even during Serbia's less sunny seasons. In the first 40 days following its November launch, the Strawberry Tree logged some 10,000 charging sessions -- or about ten charges per hour. Creator Milos? Milisavljevic was just 17 years old when he came up with the idea, and now, at the ripe old age of 22, is looking to plant new stations across other Serbian cities, through his Strawberry Energy NGO. He says these installations won't generate much revenue from consumers, but that's not really the idea:"Energy from the sun is free, and it would be unethical to charge people to use the Strawberry Tree...We are trying to inspire young people to think about the source of the energy they use, and behave and act responsibly."
