Skysails

Read about this outfit in Popular Science.

Tha age of sail has returned! With the increase in energy costs, it makes a great deal of sense. A 10-15% savings in fuel costs adds up to a lot of cash. Plus, it's cool.

I understand this outfit, along with some others, is already having an impact on private yachts, and the plan is to cater to large shipping outfits and oil tankers as well.

In a (somewhat) related note, I read that the President of Panama is hoping to expand the canal to accomadate larger container ships.
