SkySails Start Sailing to Save Fuel

Football field sized sails are finally hitting the waves, last year we mentioned SkySails initiative to sell their sails to large tanker fleets. December will see the first ship equipped with the extra-large sails head out on its maiden voyage.

The SkySails system consists of a towing kite with rope, a launch and recovery system and a control system for the whole operation. The control system acts like the autopitot systems on an aircraft, the company says. Autopilot software sends and receives data about the sail etc to make sure the sail is set at its optimal position.

The company also says it provides an optional weather routing system so that ships can sail into optimal wind conditions.The kites typically fly at about 1,000 feet above sea level, thereby tapping winds that can be almost 50% stronger than at the surface.

Old World Ways for New World Bays

I have to admit that whenever I read about “new” ideas that are really improved old ideas that we forgot in this modern age I can’t help but think there is a wealth of historical knowledge we have yet to improve upon. We are learning from the past and combining it with the future though! Take for example the ingenious idea of using a sail on a boat, or a “new” approach to gathering energy (wind). Indeed these new approaches do improve on the original idea and do so while being cheaper than the current finite resource-based approach to energy. They also tend to combine different sources of renewable energy.

A true triumphant of old world techniques like sailing and new technology is floating on the coast of Australia. A boat that has sails that also function as solar panels.

The concept is the brainchild of Robert Dane, an Australian doctor from the small fishing town of Ulladulla in New South Wales. A keen sailor and rower, Dane was watching a solar-powered boat race in Canberra in 1996 and noted that the winning boat used a solar panel inclined towards the sun. The only problem was that as the wind grew stronger the panel became a hazard and had to be pulled down.

“It intrigued me, and I started wondering how one could combine sun and wind to power a modern, seaworthy boat,” Dane says. “And then one day six months later, I woke up one morning and realized that I could use a wing sail that was at the same time a solar collector.

Wind Powered Boats

It looks like the more things change the more they stay the same. A German company, SkySails, is going to start selling a new style of sail to help large freighters move through the ocean faster.

“SkySails’ system consists of an enormous towing kite and navigation software that can map the best route between two points for maximum wind efficiency. In development for more than four years, the system costs from roughly $380,000 to $3.2 million, depending on the size of the ship it’s pulling. SkySails claims it will save one third of fuel costs.”
