Georges Mougin has long been fascinated with the potential to harvest potable water from icebergs for drought-affected regions. Roughly 20% of southern Europe faces water supply crises. Mougin has previously proposed wrapping icebergs in insulating geotextiles to reduce melting during towing. Now, he is using 3-D modeling to show how an iceberg can be towed to southern Europe using only a single tugboat.
