Scientists develop a cleaner fuel for cruise ships & other large vessels from ingredients in detergents, medicines. Scientists describe development of a new fuel mixture to ease the major air pollution and cost problems facing cruise ships, oil tankers and container ships which tend to burn the cheapest and most highly polluting form of diesel fuel. Their report was part of the 244th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society, being held here this week. George N. Harakas, Ph.D. and colleagues from the Maine Maritime Academy and SeaChange Group LLC developed a fuel by adding two ingredients to low-sulfur diesel to produce "Bunker GreenTM" fuel, a member of the Eco-HybridTM family of fuels.
