Thermoelectric and solar power generation are two promising alternative energy  solutions for the military. Power generation devices based on these two technologies aid the military by lightening soldiers' loads and allowing them to  carry fewer batteries and more equipment. Since these technologies use renewable  energy sources, Soldiers are also spared the nuisance of having to constantly  resupply. Thermoelectric power generates electricity from any adventitious  source of heat, while solar cells employ sunlight to do the same. Both  technologies are currently subject to extensive research to improve efficiency,  utility, and cost. Although they both operate on renewable energy sources, each  technology functions at a different temperature range. Thermoelectric devices  run on low temperatures, generally below 1000 K, while solar cells require  temperatures equivalent to those of the sun. Thermoelectric and solar power  generators complement each other since they are capable of producing electricity  from disparate sources. Solar produces highly efficient power during daytime but fails in darkness. Thermoelectrics can produce electricity with lower efficiency  but dramatically more sources of heat are available for thermoelectric power generation, enabling full diurnal operation. This report discusses measurements  of the properties and efficiency of a thermoelectric device and a solar cell.

This brochure provides an overview of the challenges and successes of Boston,  MA, a 2007 Solar America City awardee, on the path toward becoming a  solar-powered community. Accomplishments, case studies, key lessons learned, and  local resource information are given. The City of Boston and its Solar America  Cities program, Solar Boston, are helping to debunk the myth that solar energy  is only feasible in the southern latitudes. Boston has some of the highest  energy prices in the country and will likely be one of the first locations where  solar power achieves grid parity with conventional energy technologies. Solar Boston is facilitating the rapid development of solar energy projects and  infrastructure in the short-term, and is preparing for the rapid market growth  that is expected with the imminent arrival of grid parity over the long-term.  Solar Boston developed the strategy for achieving Mayor Menino's goal of  installing 25 MW of solar energy throughout Boston by 2015. Through Solar  Boston, the city has developed a strategy for the installation of solar technology throughout Boston, including mapping feasible locations, preparing a permitting guide, and planning the citywide bulk purchase, financing, and installation of solar technology. The city has also worked with local organizations to maximize Boston's participation in state incentive programs and innovative financing initiatives.

A conceptual definition and performance evaluation of a 100 megawatt (MW) hybrid  photovoltaic/thermal electric power plant has been carried out. The concept  utilizes the ability of gallium arsenide photovoltaic cells to achieve high  conversion efficiency at high incident fluxes and elevated temperatures. Solar  energy is focused by a field of steerable mirrors (heliostats) onto a tower  mounted receiver whose outer surface is covered with gallium arsenide  (AlGaAs/GaAs) solar cells and whose inner surface is a water boiler. The solar  cells convert a fraction of the incident radiation into electrical energy, and  the remaining energy is extracted at approximately 200 exp 0 C and used to power  a Rankine cycle turbine generator (bottoming cycle). Water is used as the solar  cell array coolant, as the thermodynamic working fluid, and as the thermal energy storage medium. Parametric studies were conducted to select conceptual  design parameters and operational characteristics which imply the lowest  levelized busbar electric energy costs. Parameters varied were collector area, condenser surface area, fan power, ambient temperature, and electric and thermal energy storage capacities. The report describes the concept, outlines the design analysis method, summarizes the parametric study results, and defines the selected plant configuration. The lowest levelized busbar electric energy generation cost, 70 mills/kilowatt-hr., was achieved with a relatively small collector area, 0.8 x 10 exp 6 square meters, and no stored energy. A rough comparison of this combined power plant with a similar photovoltaic plant, operated at lower solar cell temperature and with no bottoming cycle, showed the busbar cost of electricity (BBEC) from the combined system to be approximately 9lower.
