The ancient mariner may have been surrounded by water unfit to drink, but the U. S. Navy sees its ships as surrounded by seawater that could be converted to fuel for its fleet or aircraft. This long-time ambition is possibly being fulfilled by researchers at the U. S. Naval Research Laboratory (NRL), Materials Science and Technology Division, who recently flew a radio-controlled model airplane on seawater-derived fuel. Dr. Heather Willauer, NRL research chemist, explains, “In close collaboration with the Office of Naval Research P38 Naval Reserve program, NRL has developed a game changing technology for extracting, simultaneously, CO2 and H2 from seawater. This is the first time technology of this nature has been demonstrated with the potential for transition, from the laboratory, to full-scale commercial implementation.” The process is able to convert the recovered gases to liquid hydrocarbon fuel. Dr. Willauer’s team recently flew a replica of a WWII P-51 Mustang in the red-tail colors of the Tuskeegee Airmen. The craft’s two-stroke …
