Episode 4 - Tracking the Sun

In this episode, we explore how the sun moves across the sky during the day and why it changes its path so dramatically from season to season.  We'll then look into how engineers are designing systems that will track the sun as it passes through the sky so that photovoltaic systems can maximize their energy generation potential.  Finally we'll catch up with Dr. Bill Diong and a team of students that are looking into a whole new revolutionary way to track the sun.  So sit back and enjoy the show.
