Baltimore Water Wheel: efficient and green

Baltimore resident John Kellett developed a big water wheel that collects floating trash from the city's Inner Harbor.

"I started out thinking, 'Maybe we could bale it like a hay baler.' And then I said, 'Well, that's not necessary; maybe we can make it even simpler - we can just use the power of the runoff that brings it to collect it,'" explains John Kellett, the inventor of the mechanism.

The tentacles really look like soft coral, and round the edge of the jellyfish's umbrella like bell there is a deep blue line punctuated every twenty centimetres or so with a tiny dot, a sensory statocyst," Slater tells the Cornish Guardian.
