Ever gone swimming in New York's East River or dipped a toe into the Gowanus canal? Let's hope not, because the waters of New York are pretty polluted and will occasionally bring some trash, a whale or a member of the mafia onto our shores. Italian brothers Massimiliano Ercolani and Emanuele Ercolani have designed some conceptual artwork for a New York City water farm. In their vision, the East River could be installed with hydroelectric generators and promote organic farming. I'm not sure why these designers of Rome's DoCK Lab are interested in our water, but it is nice that someone cares.
