This report summarizes the results of research and economic analysis on a biological water-gas shift process for the production of hydrogen. The organism Rubrivivax gelatinosus CBS is a photosynthetic bacteria which can perform the water-gas shift reaction under anaerobic conditions. The report describes some of the technical issues regarding the process, addresses some claimed benefits of the process and presents some results from economic studies of different process configurations.

This report updates the 1999 economic analysis of NREL's photobiological hydrogen production from Chlamydomonas reinhardtii. The previous study had looked mainly at incident light intensities, batch cycles and light adsorption without directly attempting to model the saturation effects seen in algal cultures. This study takes a more detailed look at the effects that cell density, light adsorption and light saturation have on algal hydrogen production. Performance estimates based on actual solar data are also included in this study. Based on this analysis, the estimated future selling price of hydrogen produced from algae ranges $0.57/kg to $13.53/kg.

The Department of Energy (DOE)/National Nuclear Security Administration (NNSA) Nuclear Explosion Monitoring Research and Engineering (NEM R&E) Program is dedicated to providing knowledge, technical expertise, and products to US agencies responsible for monitoring nuclear explosions in all environments and is successful in turning scientific breakthroughs into tools for use by operational monitoring agencies. To effectively address the rapidly evolving state of affairs, the NNSA NEM R&E program is structured around three program elements described within this strategic plan: Integration of New Monitoring Assets, Advanced Event Characterization, and Next-Generation Monitoring Systems. How the Program fits into the National effort and historical accomplishments are also addressed.

The National Museum of the Pacific War presents an interview with Fred Chupp. Chupp volunteered in the Civilian Conservation Corps in 1940 and worked in Iowa. He was drafted into the Army in 1942 and trained in coast artillery. He landed at Normandy on D-Day in the afternoon with the 197th Antiaircraft Artillery Automatic Weapons Battalion. Chupp describes several combat experiences he had while in France.

The National Museum of the Pacific War presents an interview with James Eckert. Eckert joined the Army Air Forces in February of 1943. He completed aircraft welding school at Kelly Field, and served with the 40th Air Depot Repair Squadron. They traveled aboard the USS Hermitage (AP-54) to Freemantle, Australia and landed at Bombay, India in December of 1943. His squadron was assigned to Calcutta, and they repaired airplanes at Dum Dum Air Field. They also worked on Guam and Okinawa, where they arrived 3 days before the war ended. Eckert returned to the US and was discharged in 1946.

This report provides an overview of the current state of electrolytic hydrogen production technologies and an economic analysis of the processes and systems available as of December 2003. The operating specifications of commercially available electrolyzers from five manufacturers, i.e., Stuart, Teledyne, Proton, Norsk Hydro, and Avalence, are summarized. Detailed economic analyses of three systems for which cost and economic data were available were completed. The contributions of the cost of electricity, system efficiency, and capital costs to the total cost of electrolysis are discussed.

This Clean Cities final report provides information concerning different school bus types, school bus populations, school bus miles and fuel use, school bus emissions, alternative fuel school buses, and potential for alternative fuel school bus use through 2010. It is intended to provide general information concerning the size of the school bus market in the U.S., as well as to provide some quantification of the potential for alternative fuel use in school buses in the U.S., and what that might mean for petroleum displacement and emissions reductions.

This Clean Cities final report provides a general idea of the potential economic impacts of choosing alternative fuels for school bus fleets. It provides information on different school bus types, as well as analysis of the three main types of alternative fuel used in school bus fleets today (natural gas, propane, and biodiesel).

This report summarizes the results of a lifecycle assessment of a renewable hydrogen production process employing wind/electrolysis. Resource consumption, energy requirements, and emissions were determined in a cradle-to-grave manner on the operations required to transform raw materials into useful products, including the material production processes required to construct the wind turbines, electrolyzer, and hydrogen storage tanks.

The National Museum of the Pacific War presents an interview with Ludwig Matzat. Matzat joined the Army in 1944. In January of 1945 he joined the 128th Regiment, Company B, 1st Battalion, 32nd Infantry Division, at New Guinea as a replacement. Matzat served as a rifleman. His outfit also participated in the Battle of Luzon, moving the Japanese back into the Caraballo Mountains. He shares details of his combat experiences, being the sole survivor on one mission, and receiving a shell fragment wound to his back. Matzat was discharged in April of 1946.

The National Museum of the Pacific War presents an oral interview with Harlan E. McLean. McLean was born in Burlington, Iowa on 6 June 1924 and entered the Army Air Forces in December 1942. McLean took basic at Scott Field, Missouri and was sent to Michigan State University for enrollment in a college training detachment. He describes his life while taking classes in preparation for cadet training. Upon completion of the college courses, he was sent to Vernon, Texas for primary flight training, then to Enid, Oklahoma and Victoria, Texas for secondary flight training. He graduated and was commissioned 27 February 1944. His first assignment was at Chatham Field, Savannah, Georgia where he trained in B-24s. After completion of the transitional training he went to Mitchell Field, New York, to await an overseas assignment. After arrival in England, he was assigned to the 351st Bomb Group, 508th Bomb Squadron as a B-17 co-pilot. He flew 24 combat missions and describes several. After Germany surrendered, McLean’s group transported Frenchmen, who had been prisoners of the Germans, back to France and comments on their physical condition. He returned to the United States during June 1945 and went into the Reserves. He recalls …

In a ''green roof,'' a layer of vegetation (e.g., a roof garden) covers the surface of a roof to provide shade, cooler indoor and outdoor temperatures, and effective storm-water management to reduce runoff. The main components are waterproofing, soil, and plants. There are two basic kinds: intensive and extensive. An intensive green roof often features large shrubs and trees, and it can be expensive to install and maintain. An extensive green roof features shallow soil and low-growing, horizontally spreading plants that can thrive in the alpine conditions of many rooftops. These plants do not require a lot of water or soil, and they can tolerate a significant amount of exposure to the sun and wind. This Federal Technology Alert focuses on the benefits, design, and implementation of extensive green roofs and includes criteria for their use on federal facilities.

The National Museum of the Pacific War presents an interview with Bryce Taylor. After finishing high school in 1942, Taylor joined the Marine Corps and had basic training at San Diego. After basic, Taylor was assigned to the base band in San Diego. He arrived at Pearl Harbor in February, 1944 and was part of the base band there for two years. Taylor recalls playing Taps in the evening several times on the USS Arizona (BB-39). His band also played regularly at the hospital at Aiea. After a while, he was recruited by Bob Crosby to tour parts of the Pacific and play concerts: Saipan, Guam, Iwo Jima. He returned home and was discharged in 1946.
