Video: Kite-powered ships in action

We mentioned the SkySails system a few months ago.

Hank at EcoGeek picked up on this video of the kite-powered ships in action. (Ta Hank). He says:

Per square foot of sail, it’s 3x more effective than traditional sails. It does not require extensive training to deal with, and there’s no need for maintenance during travel. The sail literally unfolds and folds itself at the touch of a button. While deployment isn’t particularly fast, it is extremely simple and entirely automated. Seeing this thing in action is really fantastic, and I can’t imagine that, within the next five years, these won’t be being installed on thousands of ships of all shapes and sizes. And, of course, this will reduce emissions from the shipping industry as much as 20% per ton shipped.
