This video features world-famous underwater adventurer Jacques Cousteau, this time on a journey in which the treasure is on the surface of the sea. Along with Lucien Malavard and Bertrand Charrier, Cousteau invented a new kind of sailing vessel using a state-of-the-art, high-tech turbo sail. The tall, computer-controlled cylinder of metal sails the ship much like a conventional canvas sail, but is up to six times more efficient. The viewer follows Cousteau on the windship's maiden voyage from Tangier to New York, which ends in disaster when the turbosail is lost two days from the boat's destination. Cousteau then builds a second ship, the Alcyone, with two turbosails and more sophisticated controls. This time, his revolutionary boat makes the passage safely, and Cousteau and his crew sail victoriously into New York harbor.
