Sometimes a solution to a problem comes along that is simple and elegant and deserves to be promoted. This is one of those situations. The Inner Harbor of Baltimore, MD, is fed by the Jones Falls river watershed to the north. People carelessly leave trash on the ground and in the streets instead of in proper receptacles. When it rains, this trash is washed into the river and then into the Inner Harbor. It is ugly and unhealthy. Clean-up has been an ongoing chore for the city.
Since May 2014, the job of trash removal from the river has been made much easier with the use of a current-driven and solar-powered water wheel. Current flows from right to left. This perspective view shows two floating orange booms which guide the trash into the device. The device brings the trash up a conveyor and dumps it into a dumpster. If you are interested is seeing a screenshot of the 2014 trash totals by category, monthly precipitation, tonnage and volume, follow this link. The wheel continues to operate during the winter months.
