Plastiki

These guys are building a catamaran out of reused plastic bottles (!!) and sailing to the Garbage Patch in the Pacific to raise awareness of waste/plastic in the oceans. Their site is incredibly beautiful and well done:  www.theplastiki.com

It's put on by David de Rothschild with big sponsors, what kind of budget I wonder??  They used dry ice in the plastic bottles for stiffness and used some fancy tech to make the 60ft catamaran sea worthy.

I particularly liked the exercise bikes on the stern of the boat that can generate electricity and keep the crew fit, while looking down at the fish... I always thought having a hot tub on the boat would be the ultimate luxury but now I have to reconsider...
