“Mr. Trash Wheel” | The Inner Harbor Water Wheel

This unusual boat, nicknamed “Mr. Trash Wheel” runs along the canals and the harbor the American city of Baltimore, cleaning debris from the water. Garbage trucks is moving slowly through the water, while the water wheel pulls out all the debris from the water. All the trash left in the tanks, and the water back into the canal.

During 1.5 years of work barge managed to collect a huge amount of plastic and metal cans, plastic bags, cigarette butts, sticks and other debris. Seeing the positive trend, the barge supplemented by solar panels, helping to turn the wheel. If the work of garbage collection will continue at the current pace, then after 4 years in the channel and the harbor you can swim.
