Water Wheel operating in a rain storm (Baltimore, MD)

Early last month, theWaterfront Partnershipof Baltimore; Constellation, the renewable-energy arm ofExelon Corp.; and the Maryland Port Administration together launched the Inner Harbor Water Wheel, an amazing new trash removal system that is capable of picking up 50,000 pounds of trash every day. The automated system, designed by John Kellett and Clearwater Mills, brilliantly combines old and new technology. It uses solar power and water current to turn a giant spinning wheel — much like a traditional mill wheel — that scoops garbage flowing down the Jones Falls stream and deposits it into a dumpster for disposal. The garbage it collects is towed to a nearby waste-to-energy plant where it can be put to productive use.
