After what feels like years of concept renders and photos of the hairy David de Rothschild accompanying gushing magazine pieces about his plastic bottle boat, the Plastiki will set sail this month across the Pacific Ocean.

If you'll remember, the boat was constructed using 12,000 plastic 2-liter bottles, which have been pressurized using dry ice powder, making it buoyant enough to carry four people on the 11,000 miles from San Francisco to Sydney. It'll take 100 days they think, with the electricity coming from solar panels, wind turbines and exercise bikes that the four crewmembers will be using.

It's the ultimate eco-warrior ship, with even a small garden growing herbs and veggies included on the 60-foot boat. At least if they sink, they've got an awful lot of bottles to put messages in. [Plastiki via TG Daily]
