John Kellett, the former director of Baltimore’s Maritime Museum, used to cross a footbridge over Jones Falls, the largest tributary feeding into Baltimore’s Inner Harbor, every day on his way to work. “When it rained, there was a river of trash flowing down,” he told me. He had spent twenty years working on the harbor, primarily in environmental education and shipbuilding, and had a deep knowledge of its hydrodynamics and history. City officials, he told me, “said they were open to ideas, so I started sketching.” He drew plans for a machine powered by an old-fashioned water wheel—a technology that had once been a staple throughout the city—designed to intercept trash at the mouth of Jones Falls, which is the main source of harbor pollution. A prototype was installed in 2008. By 2014, Kellett’s invention was reborn as Mr. Trash Wheel—a fifty-foot-long machine, weighing nearly a hundred thousand pounds, that resembles a friendly mollusk, with giant, googly eyes and its own Twitter account.
Five years later, Mr. Trash Wheel has spawned three replicas around Baltimore—Professor Trash Wheel, Captain Trash Wheel, and another that was announced last week but has yet to be named or installed in the water. Continue reading
If Mr. Trashy has a silly ring to it, so be it. The medium is the message:
The Inner Harbor Water Wheel, or “Mr. Trash Wheel” to locals, combines old and new technology to harness the power of water and sunlight to collect litter and debris flowing down the Jones Falls River.
The river’s current provides power to turn the water wheel, which lifts trash and debris from the water and deposits it into a dumpster barge. When there isn’t enough water current, a solar panel array provides additional power to keep the machine running. When the dumpster is full, it’s towed away by boat, and a new dumpster is put in place. Voilà!
Thank you, Mr. Trash Wheel.
