One man’s trash is another man’s treasure, right? In Taiwan, the answer is yes: a company there called Miniwiz Sustainable Energy Development Ltd has created a boat out of trash. It’s called the Polli-boat, and it’s made up of everything from plastic bottles to old advertising banners. The flotation system uses interlocking plastic bricks that lock together with enough force to hold up under the pressure of sailing. It even has solar panels that help power the boat when there’s no wind!
