Alcyone research vessel. Aerial view of the research ship Alcyone in the brown waters of the Betsiboka estuary, Madagascar. This vessel is operated by the Cousteau Society, a foundation set up by the scuba pioneer Jacques-Yves Cousteau to promote conservation of water habitats worldwide. It uses Turbosail technology. A fan draws air into each of its two 10-metre-tall masts. This creates forward lift that surpasses that attained by a normal sail, and reduces the ship's fuel consumption by a third. The red colour of the water is due to the sediment that it carries.
