Here’s a real and operating environmental solution that combines solar power with simple automation to remove up to 20 tons of trash a day from Baltimore’s Inner Harbor.

Part of the problem with big ongoing cleanups is manpower, cost of labor, and the sheer overflowing volume of trash created by humans. Automated methods don’t get tired, don’t need raises and don’t need health benefits.

This technology hopefully will end up deployed on more waterways around the world.
