The Plastiki is a 60-foot (18 m) catamaran made out of 12,500 reclaimed plastic bottles and other recycled PET plastic and waste products. The craft was built using cradle to cradle design philosophies and features many renewable energy systems, including solar panels, wind and trailing propeller turbines, and bicycle generators. The frame was designed by Australian naval architect Andrew Dovell. The boat’s name is a play on the 1947 Kon-Tiki raft used to sail across the Pacific by Norwegian explorer Thor Heyerdahl, and its voyage roughly followed the same route.
