The Bottsand class oil recovery ships cruise just like any other vessel, until they reach an oil spill. Then, they open like Pac-Man, transforming into a machine that can clean the oil from 140 cubic metres of water per hour.
Created by the Deutsche Marine - the German Navy - the Bottsand-class opens in half, creating an area to trap water to process in its 790 cubic metre tank. Obviously, one is not enough to clean BP's oilpocalypse in the Gulf of Mexico, but at this point in this huge disaster, anything can help. [Gcaptain]
