Sailing ships once carried much of the world’s cargo across the seas, until canvas sheets were replaced by low-grade “bunker” oil. Now it appears that wind power is about to make a comeback, in the form of rigid “sails” that double as solar panels. The patent-pending technology, called the Aquarius Solar and Wind Marine Power System, is being developed by a company called Eco Marine Power. The dream of a high tech, sustainable energy cargo ship has been percolating for a number of years now, but it hasn’t caught on in a big way, so let’s see if this new system is The One.

Wind Power for Cargo Ships

At first blush, wind power for today’s ultra-huge cargo ships looks like a nice idea, but just not possible. The scale alone makes it seem impractical. However, that hasn’t stopped anyone from trying. In recent years a German company has come up with a parachute-like design for cargo ships that includes sails the size of football fields, and a British company has developed a more traditionally styled, rigging-free sail system for smaller cargo ships.
