New Sails for Old Ships

Abstract

The world’s 100,000 cargo ships produce about as much carbon emissions as Germany. One of the ways to reduce those emissions (and slash fuel costs) is to borrow a technology from the past and harness wind power. By harnessing advanced simulation tools, engineers have developed promising fuel-saving technologies that do not necessarily resemble the tall masted ships of the past. This article shows how Europe is leading the way.
