Trash wheel saves ocean from Baltimore’s plastic-filled rivers

The video discusses a successful invention, Mr. Trash Wheel, designed by John Kellet to tackle plastic trash in Baltimore's harbor. Inspired by the need to address trash accumulation after rain, Kellet combined a water wheel with a hay baler design. The machine, powered by the Chesapeake River's current, uses a conveyor belt to collect various debris, funneling it into a dumpster. Since its launch in 2014, Mr. Trash Wheel has intercepted over 1.5 million tons of garbage, showcasing its effectiveness.
