The Plastiki is a 60 foot Catamaran whose hull is made from approximately 12,000 reclaimed plastic bottles. The catamaran, and its crew of scientists, creatives, and adventurers, is sailing from San Francisco to Sydney, Australia in order to inspire creative design solutions to our environmental dilemma. The Plastiki is to be launched late 2009 from San Francisco.
The Plastiki website is really fun, interactive, and educational. You can also follow the Plastiki development and expedition at http://www.theplastiki.com/.
