This trip to the Yonkers Pier took this science class to a very special barge. The Science Barge is a prototype sustainable urban farm developed by NY Sun Works and acquired by Groundwork Hudson Valley in October, 2008 to be operated as an environmental education center. The Science Barge greenhouse, floating on the Hudson River, grows an abundance of fresh produce including tomatoes, melons, popcorn, peppers, eggplant, and lettuce with zero net carbon emissions, zero pesticides, and zero runoff. <br><br>All of the energy needed to power the Barge is generated by solar panels, wind turbines, and biofuels while the hydroponic greenhouse is irrigated solely by collected rainwater and purified river water, thus operating completely u201Coff the grid.u201D It is the only fully functioning demonstration of renewable energy supporting sustainable food production in New York. <br><br>It was a very educational and exciting trip for the students. <br><br>Photographer: Faye Rhani
