AT&T has deployed 25 solar charging stations around New York's five boroughs in a pilot program in partnership with the city. These 12-feet tall charging stations, designed by Brooklyn firm Pensa, are located in public spaces like parks, plazas, and beaches for anyone to use, regardless of cell carrier. Each station gets its power from three 15-watt solar panels, though they are also equipped with a 168Whr battery to charge devices in the evenings or days without sunshine. Users can plug into one of six USB ports or the attached Apple 30-pin and 8-pin connectors, charging a phone in around two hours. The project is estimated to cost up to half a million dollars, and AT&T may bring it to other cities if it's considered successful. Pensa had pitched its Street Charge design last year, and the firm was also responsible for the novel wire-bending CNC machine, DIWIRE.
