Research program of U S Bureau of Ships is in final phase;literature survey and screening phases are completed;on basis of tests, fabrication studies and cost analyses most promising materials are steels 4330M and 17-4ph (H1025) with protective coatings, and 2 titanium alloys (8AL-2CB-1TA) and (6AL-4V);most promising coatings are polyurethane rubber and neoprene rubber base coatings;coated HY-100 steel is satisfactory for low performance foils;glass laminates are of particular interest as foil materials and are under study;no "off shelf" material is ideal for high speed foils.

Kowalski, T.The Author graduated from Glasgow University in 1944
then completed the three year Warship Design course at the Royal Naval College Greenwich England. He worked for the British Ship Research Association in London England from 1947–1949. After two years as Lecturer at McGill University Montreal he joined the Royal Canadian Navy in 1951 as a Constructor Officer. In 1960 he became a Research Engineer at the Davidson Laboratory of the Stevens Institute of Technology and worked in the field of ship hydrodynamics. Having obtained a Master of Science degree in Nautical Engineering from Stevens Institute of Technology he held the position of Assistant Professor at the United States Naval Academy from 1963–1965.

Towing tank experiments to determine effect of additive (polyethylene oxide) on turbulent frictional resistance of three models (mariner ship model, destroyer model, flat plate);results indicate possibility of reduction of viscous resistance in full scale flows by introduction of extremely minute amounts of so-called non-Newtonian additives into boundary layer;ship model resistance decreased by about 25% of total drag which consisted of viscous and wave making components.

T his paper anticipates a future need for welding processes in depths to 5000 meters. Arc cutting and joining processes are found to be the most suitable for depths in excess of 1500 meters because they avoid the problem of gas liquification. The underwater arcs are enhanced by constricting effects produced by the deep ocean environment, and no problem with heat generation is expected. Argon or nitrogen shielded arcs are advised for deep sea work. Their use can lead to reduced power requirements, control of penetration and metal transfer rate, and a reduction in porosity and slag inclusions. The cumbersome diving dress required to offset the cold and the problem of visibility in bottom waters is expected to produce the most serious operating difficulties for the welders. Cryogenic gas transport and experimentation in the laboratory and at sea are recommended.

This article presents a critical assessment of 40 years of research that may be brought under the umbrella of energy efficiency, spanning different aggregations anddomains—from individual producing and consuming agents to economy-wide effects to the role of innovation to the influence of policy. After 40 years of research, energy efficiency initiatives are generally perceived as highly effective. Innovation has contributed to lowering energy technology costs and increasing energy productivity. Energy efficiency programs in many cases have reduced energy use per unit of economic output and have been associated with net improvements in welfare, emission reductions, or both. Rebound effects at the macro level still warrant careful policy attention, as they may be nontrivial. Complexity of energy efficiency dynamics calls for further methodological and empirical advances, multidisciplinary approaches, and granular data at the service level for research in this field to be of greatest societal benefit.

JR. USN attended the U. S. Naval Academy Preparatory School the U. S. Coast Guard Academy and the University of Virginia where in 1939 he received the S.B. degree in Engineering and in 1940 the degree of Electrical Engineer. In 1942 he was graduated with the S.M. degree in Communication Engineering from Cruft Laboratory Harvard University and that summer completed the Navy Course in Radar Engineering at Massachusetts Institute of Technology. Subsequently for several years he was engaged in lecturing to officers of the Armed Forces assigned to the radar schools at Harvard and Princeton Universities. He has had four tours of duty in the Electronics Design and Development Division Bureau of Ships two at the U.S. Naval Research Laboratoryone at the Signal Corps Engineering Laboratories (Evans Signal Laboratory)and one at the Philadelphia Naval Shipyard. His experience includes amateur
naval and broadcasting operation. In 1951 Commander Harrison was selected for training in Advanced Science at Harvard University under sponsorship of the Office of Naval Research. This program led to the M. Eng. degree in 1952 and Ph.D. degree in Applied Physics in 1954. Commander Harrison is presently Electronics Officer on the Staff of Commander Operational Development Force. He is a member of several societies and associations including the Harvard Chapter of the Society of Sigma Xi.
