Sergej Mahnovski, Director of the Mayor�s Office of Long-Term Planning and Sustainability, delivers remarks at a news conference aboard the world�s largest solar boat, Switzerland�s MS Turanor PlanetSolar, on June 18, 2013 at North Cove Marina in New York. PlanetSolar is in New York City as part of its DeepWater Expedition 2013 tour with scientists on board from the University of Geneva. The solar-powered boat runs exclusively on energy from the sun and eliminates the need for fueled electricity, allowing researchers to collect uncontaminated data along the Gulf Stream with high-tech instruments that track changes in ocean currents and climate. Solar panels cover more than 5,554 square feet (516 square meters) of the ship�s surface. AFP PHOTO/Don Emmert
