This article reads like a freshman essay. Autonomous boats! Self assembly! 3D printing! Ignores the big issues: * For large boats, fuel is expensive. The person operating the boat is a tiny fraction of the cost. * Maybe electricity is the idea? The article doesn't say. * Shifting city garbage to the night? Collecting aggregate garbage isn't really the problem. The problem is getting it from the alley to the truck. No boat is going to help here, unless you're in Venice. This article doesn't make a lot of sense to me. Even the model doesn't accurately represent the dreams of the article; it clearly is not a 2x4m hull.
