The “Plastiki Expedition” by environmentalist David de Rothschild is attempt to finally put all of the discarded plastic water bottles we use daily to good use. His project is to build a 60-foot boat made entirely out of recycled materials such as the bottles and then sail it across the entire Pacific Ocean! From his descriotion: “The boat will be designed as a response to the problem that plastics present. The design also aims to be completely self-contained in terms of its energy generation, fresh water creation and waste treatment.” Check out the details at the link below.
