In time for the upcoming fall semester, Ben-Gurion University of the Negev in Beersheba installed a number of cellphone charging stations where passersby will be able to boost their mobile devices by means of solar energy.Each stand can charge up to 12 phones, allowing those in need of battery power to plug in their USB cables and sit on a bench in a shaded area while waiting, the university said.The project is part of the larger Green Campus initiative that also includes the placement of 39 new recycling facilities for bottles and cans and two electronic waste bins.
