It’s called the Inner Harbor Water Wheel, and though it moves slow, it has the capability to collect 50,000 pounds of trash per day. The timing for John Kellett’s solar-powered creation is crucial—hands and crab nets simply can’t keep up with the growing amount of wrappers, cigarette butts, bottles and other debris carried from storm drains into the harbor.

The current of the river provides power to turn the water wheel, which lifts trash and debris from the water and deposits it in a dumpster barge.
