Cargo Ship Propelled by… A Kite?

Last week the MS Beluga Skysails launched from Bremerhaven, Germany on a trip across the Atlantic Ocean. Upon its arrival, the locals in Venezuela noticed that something was amiss. The 140 meter long cargo ship was being pulled across the water by a giant kite. But then again, a new free/green secondary propulsion system would alarm even the most salted of sea dogs.

Even though it’s not completely relying on the kite as its main source of propulsion it is estimated to reduce fuel costs by 10 – 35%, which in turn means less carbon emissions. The kite itself is shaped like an aircraft wing and it is able to adjust with different air conditions.

Operating range for the kite is about 100m – 300m above the surface. Higher altitudes have stronger winds that also remain stable and consistent. It can be flown in a variety of wind conditions and has the ability to be positioned in other areas around the ship to maximize efficiencies.

I’ve been power kiting for a little less than a year now, so naturally I wanted some specs on this massive kite. To give you an idea, I’m 6′3″ at 190lbs and a 5.5 meter power kite can lift me plain off the ground on a windy day. That ship weighs a slight bit more; to compensate they’ll be using a kite that is a massive 160sqm in size.

A kite that size, in the right weather, would have the ability to pull over 200 people directly into the clouds without blinking. Now that’s power.
