Solar powered telephone. Roadside emergency telephone powered by photovoltaic cells fixed on top of the telephone's pole. The cells charge batteries providing an independent power source to boost the signal used to carry the call. The system is ideal for remote sections of the telecommunications network where it would be costly to set up power lines. Photographed in Maui, Hawaii, USA.
