Quartz reports on a weird solar and water-powered gizmo sitting in Baltimore’s Inner Harbour that is able to collect garbage floating down the river. The wheel, which even has a Twitter account, is able to collect 23 metric tonnes of garbage each day that "would otherwise have flowed through the Chesapeake Bay en route to the Atlantic Ocean."
Between May 16 and June 16, the wheel intercepted about 50 tons (46 tonnes) of trash that had drifted down to the harbor from city streets and would otherwise have flowed through the Chesapeake Bay en route to the Atlantic Ocean.
“Major cites with tightly controlled tributaries are the perfect candidates for this technology,” says Thaler. The water wheel can capture debris from an entire watershed and prevent them from flowing into the ocean if it’s placed correctly, as it has been in Baltimore.
