79729S Ocean currents constitute a potentially enormous renewable energy resource; however, existing technologies for capturing this energy are only in the prototype stage, are small in scale (less than 1 megawatt), and are not grid-connected. Although there is a considerable overlap in technology with the more mature field of wind energy, new robust technologies will have to be developed that ar ...

79659S As direct drive wind turbines increase in size, the diameter of their generators increases to the point where it is no longer possible to ship them as a single unit. While some companies have addressed this issue by using wound rotor generators that can be assembled on site, this approach suffers from the inherent lower efficiency and reliability of the wound rotor technology. To date, no ...

78150B The catalytic reforming of diesel fuel in Solid Oxide Fuel Cell (SOFC) systems must overcome a number of challenging issues: (1) the deactivation of the catalyst by sintering and sulfur poising; (2) the requirement for a large fuel processing system as a result of high space velocity requirements; and (3) the lack of durability of the catalysts, which require frequent replacement due to "c ...

78072S III-V nitride-based, high brightness, UV and visible light emitting diodes (LEDs) are of a great interest for general illumination, but the low light output efficiencies of current high brightness LEDs are still inadequate. A key material issue preventing the achievement of higher light output efficiency in LEDs is the poor crystalline quality of the nitride epitaxial layers that result fr ...

78276S Sources of high-peak-power millimeter-wave radiation are needed for development and testing of components and structures for a future multi-TeV electron-positron collider. A pulse compressor must generate the 200 MW pulses needed to develop structures for the CERN two-beam accelerator, or for a similar high-gradient millimeter-wave accelerator. This project will develop high-power switch ...

78728 A stand-alone 200 MW radio frequency (RF) test station is needed for developing accelerator structures and components for a future high-gradient multi-TeV collider, such as CLIC. In addition, a high-power RF window will be needed to isolate the test station from a structure element under test. This project will develop such a window for use in the frequency range 30-35 GHz, along with a h ...

78413SThe international high-energy physics community has decided to develop superconducting radio frequency (RF) technolgy to be the basis for the International Linear Collider, a 0.5 - 1.0 TeV electron-positron collider that is intended to complement the Large Hadron Collider. The 1.3 GHz RF power needed to drive this accelerator is now planned to be supplied by 600-1200, 10-MW peak power multi ...

78070S The realization of a future multi-TeV electron-positron collider rests, among other factors, upon the development of structures that can sustain high acceleration gradients. This project will develop a rectangular waveguide containing planar dielectric slabs as a high-gradient accelerator structure. This Ka-band, dielectric-loaded rectangular accelerator structure will have high shunt i ...

78600S The efficiency of solid oxide fuel cells can be increased by anode gas recycling. Therefore, in this project, a motor driven, high-temperature Anode Gas Recyle Centrifugal Blower will be designed, built, and demonstrated. A high-speed direct drive motor, combined with foil gas bearing technology, will result in a low cost, efficient, small, oil-free, and reliable blower. The approach wi ...

78363S In order to perform physics experiments with higher energy collisions, more energy and luminosity will be required. More luminosity means larger apertures and bigger magnets. In turn, the development of high field magnets will require higher performance, lower cost Nb3Sn superconductors. This project will develop and demonstrate an economical powder-in-tube (PIT) Nb3Sn process for use i ...
