Warren Buffet invests in trains: http://www.cnbc.com/id/20519680/ http://www.cnbc.com/id/20519680/ Freight ship with parachute-like sail: http://www.shippingtim

  Interesting idea, but that sail looks tiny for that size ship. I can't imagine it does much.

    the gas savings outweighed the cost of the parachute or they wouldn't have done it. 1% savings on a ship that size is significant money.

    The sails in the picture are being winched in. Normally, they fly like a kite, about 200 m above the ship, and tow it forwards. The winds are much stronger up there. It also looks like the kite has been partially furled - the picture on Wikipedia looks much bigger: http://en.wikipedia.org/wiki/MS_Beluga_Skysails http://en.wikipedia.org/wiki/MS_Beluga_Skysails
