A natural gas powered container ship.

The kite thing is pretty cool.
From what I hear they aren't so much using the kite to save a ton of fuel. Its being used to go faster and save some fuel.
Above all its reducing the time and cost of international commerce.

I have been on top of wind turbines, I know all about how strong the wind gets once you get up about 150 feet off the ground. Its a gentile breeze on the ground, then you go up and its gale force, go back down to the ground, gentile breeze again.

So go tell the Ukranians to move back into Chernobyl.

Vindskip - a greener and more cost-effective future for shipping - Ship Technology

Right now, we are still in the conceptual stages. The idea is being tested in wind tunnels, optimised by computational fluid dynamics and will then be tested in a model tank until a final defined form and function is reached. The tank testing is scheduled to start in April 2015.
...
We estimate that the engineering and construction will take approximately two to three years. So, with a bit of luck, our first ship will be sailing by 2019.

I see opportunity here for slats and blown flaps as on a STOL aircraft.
