Mirrors

Almost a decade after they installed the first solar photovoltaic (PV) panels on the rooftops of the university buildings, engineers at the Ateneo de Davao University explore tapping another power from the sun: heat captured in this parabolic dish of the concentrated solar thermal power facility in Bangkal campus. Unlike PV cell that converts light into electricity, CSP uses mirrors to concentrate sunlight into its receiver to produce heat--which is then used to spin a turbine or power an engine to generate electricity.
