One of the most awesome sights in the Sidney Harbor is the fully solar-powered ferry known as the "Solar Sailor." This boat, designed by Robert Dane, uses both solar power and wind to reduce it's emissions to half of standard ferries. This Ferry uses a flexible solar sail, Which is almost like a pair of wings. When the weather is good, the solar panels on the wings can travel by the rays of the sun. Likewise, when there is a storm, the wings can "fly solo." The wind will push the ferry along.
