“In fifty years time people will look back at boats of the 20th Century and they’ll say “where are the wings”?” says Robert Dane, CEO of Solar Sailor. His company’s aerofoils move to help a boat take advantage of the best wind and sun conditions and just may revolutionize shipping. They’re currently being installed on Chinese freighters and Hong Kong ferries.

In this video, we board the Solar Sailor ferry in Sydney Harbor (Australia) for a tour of the boat with engineer Craig Thomsen.
