Maybe you’ve heard of David de Rothschild, British banking heir, and his plan to sail his catamaran (named Plastiki!) which is made from various kinds of trash. Trash floats it. Next month de Rothschild plans to sail from San Francisco to a huge floating garbage patch in the Pacific, and from there, to Australia. His objective is to publicize environment ills. Nearly 12,000 two-liter bottles buoy up the Plastiki. As you may have guessed, the structure of the boat is made from recycled plastic. The drawing below looks like a toy boat, but actually it is huge. That’s a cabin on top, made from Styrofoam cups.
