The global cargo shipping industry accounts for roughly 2 percent of all greenhouse emissions worldwide. That may be about to change. In a big way.

Wallenius Marine has announced the development of a prototype cargo ship that is powered by a series of massive retractable “sails” that resemble airplane wings. The ship, the OceanBird, will reportedly be able to carry the equivalent of 7,000 cars across the ocean while cutting carbon emissions by 90 percent.

When fully extended, the OceanBird’s upright, wing-like sails stand some 80 meters high, and use the power of rushing air to propel the ship forward, achieving a speed nearly matching that of ships powered by fossil fuel.
