The wheel is powered by water currents and solar panels (!). It sits at the mouth of the Jones Falls where it empties into the Northwest Branch of the Patapsco River. Trash is funneled by booms to a conveyor that takes it to a dumpster where it can be hauled off and processed.
This is an exciting and innovative solution for urban waters facing trash problems. It also makes an amazing design for a cake.
