Assessment of Energy Production Potential from Tidal Streams in the United States

Description: Tidal stream energy is one of the alternative energy sources that are renewable and clean. With the constantly increasing effort in promoting alternative energy, tidal streams have become one of the more promising energy sources due to their continuous, predictable and spatially-concentrated characteristics. However, the present lack of a full spatial-temporal assessment of tidal currents for the U.S. coastline down to the scale of individual devices is a barrier to the comprehensive developmen… more

Overview of the geothermal energy development program at the Lawrence Livermore Laboratory

Description: The program consists generally of development of advanced conversion systems, with strong emphasis on a systems approach to find solutions of the problems of scale formation, corrosion/erosion of materials, spent brine disposal and solids handling, and development of reliable, efficient energy conversion systems with strong emphasis on development of the total flow concept. The status of the various parts of this program is reviewed briefly. (MHR)

The Status of Thermophotovoltaic Energy Conversion Technology at Lockheed Martin Corporation

Description: In a thermophotovoltaic (TPV) energy conversion system, a heated surface radiates in the mid-infrared range onto photocells which are sensitive at these energies. Part of the absorbed energy is converted into electric output. Conversion efficiency is maximized by reducing the absorption of non-convertible energy with some form of spectral control. In a TPV system, many technology options exist. Our development efforts have concentrated on flat-plate geometries with greybody radiators, front sur… more

Optical Coatings for Thermophotovoltaic Spectral Control

Description: The efficiency of thermophotovoltaic (TPV) energy conversion is dependent on efficient spectral control. An edge pass filter (short pass) in series with a highly doped, epitaxially grown layer has achieved the highest performance of TPV spectral control. Front surface, tandem filters have achieved the highest spectral efficiency and represent the best prospect for even higher spectral efficiency for TPV energy conversion systems. Specifically, improvements in the physical vapor deposition proce… more

Lawrence Livermore Laboratory heavy ion fusion program

Description: In the large fusion program at Livermore we are actively doing research in most areas of inertial confinement fusion. The areas in which we are funded for research specific to heavy ion fusion are: (1) target design; (2) energy conversion chamber design and (3) ion beam propagation in the combustion chamber. There are two main thrusts to the target design effort: (1) development of targets which are optimally suited to heavy ion fusion power production and (2) fundamental studies of the beam-ta… more

Thermophotovoltaic Array Optimization

Description: A systematic approach to thermophotovoltaic (TPV) array design and fabrication was used to optimize the performance of a 192-cell TPV array. The systematic approach began with cell selection criteria that ranked cells and then matched cell characteristics to maximize power output. Following cell selection, optimization continued with an array packaging design and fabrication techniques that introduced negligible electrical interconnect resistance and minimal parasitic losses while maintaining o… more

Novel Nuclear Powered Photocatalytic Energy Conversion

Description: The University of Massachusetts Lowell Radiation Laboratory (UMLRL) is involved in a comprehensive project to investigate a unique radiation sensing and energy conversion technology with applications for in-situ monitoring of spent nuclear fuel (SNF) during cask transport and storage. The technology makes use of the gamma photons emitted from the SNF as an inherent power source for driving a GPS-class transceiver that has the ability to verify the position and contents of the SNF cask. The powe… more
