The concept that we can capture the sun’s energy is quite amazing. In Zadar, Croatia the Sun Salutation is a public art installation that uses solar cells to collect the sun’s energy, and then releases it overnight in the form of a light show that is shaped by the wave activity below. It is fascinating to see. Even more fascinating was the mood during a beautiful sunset. The lights seemed to brighten as the sun disappeared, the crowds grew louder cheering the moving art. The sun had just set but was greeting us.
