SKY SAILS

I love it when ancient concepts circle back around and, with some ingenuity, become an integral component advancing our current technologies.

The sky sails have been recently used by shipping companies on transoceanic voyages with immense fuel savings and significant dampening of their environmental impacts. And, forward-thinking companies can get some positive PR from adopting green technologies in their inherently resource-hungry businesses.
