Editor's Note: A team of Rensselaer Polytechnic Institute students was traveling up New York's Hudson River this week on the New Clermont , a 6.7-meter boat outfitted with a pair of 2.2-kilowatt hydrogen fuel cells to power the boat's motors. Their journey began September 21 from Manhattan's Pier 84 and was to cover 240 kilometers (at a projected speed of 8 kilometers per hour). After making several stops along the way, the crew originally expected to arrive back at Rensselaer Polytech's campus in Troy, N.Y., on September 25. This is the fourth of Scientific American.com's blogs chronicling this expedition, called the New Clermont Project . [More]
