Is it possible? Well, some certainly think so. Mougin has been working with French design firm, Dassault Systèmes, to use 3D simulations and modeling to create real-world scenarios, including fuel supply, the melt rate of the berg, ocean currents and other weather conditions the tugboat and attached berg may encounter on their journey. They figure that by selecting an iceberg of the right size and shape -- not too big to pull but not too small that it melts quickly, and nice and flat on the top to minimize drag -- then it would make sense to pull it to a location where the water is needed. Theoretically, anyway.
