Mr Trash Wheel - Baltimore's Inner Harbor

This "contraption" lives in the water at Baltimore's Inner Harbor.  It has a water wheel that turns when there is a current and collects trash and loads it into a dumpster in the center.  If the current is not sufficient turn the wheel, the solar panel will kick in and take over.  

In February 2016, it collected 20.76 tons of trash out of the water which included 18,000 polystyrene containers, 14,000 chip bags, 13,000 plastic bottles, 11,000 grocery bags, 163,000 cigarette butts, and misc other stuff.
