That is pretty amazing. I never thought we would see wind powered commercial sailing ships again.
It will be interesting to see if it proves viable over time.

I don't think that style of sail is the answer --it seems very vulnerable, *particularly* in the north Atlantic routes. But maybe in the Pacific routes (Calif-Hawaii, comes to mind).
The tubular turbine-like sails might prove to be worthwhile, though.
