The feasibility of modifying an aqueous naoh solution to provide a higher lift and less corrosive absorbent for use in absorption cycles is examined. the properties that are projected (and in some cases already confirmed) for the modified absorbent have long been sought by researchers in the… More

Typically, a cogeneration system designer must choose between a reciprocating engine, which yields excellent electrical efficiency but low useful thermal output or a gasturbine, which yields a large thermal output but less electricity. the proposed improvement, when applied to a reciprocating engine… More

75990-Waste heat streams represent an enormous untapped energy resource. The smaller the quantity and temperature of the waste heat, the more difficult it is to convert it to power. Yet, the smaller waste heat streams are available in greatest number. This project will develop a new absorption… More

79186S Fresh water is growing scarcer and costlier. Power production is the second largest user of fresh water, accounting for 130 billion gallons daily. Unfortunately, current approaches to reducing the water used in power production increase the cost of power and reduce the efficiency. Cycle… More

As DoD develops more complex weapons, electronics and computer platforms there is an increasing demand for both power and cooling. This highlights the urgent need for innovative designs in environmental control and electric generation. Electric generation releases waste heat. Heat-activated… More

Fresh water is growing scarcer and costlier. Power production is the second largest user of fresh water, consuming about 25 gallons per kilowatt-hour in coal-fired plants. In particular, steam power plants, which use air-cooling to reduce water usage, suffer large economic and efficiency… More

As the Department of Defense develops more complex weapons, electronics and computer platforms, there is an increasing demand for both power and cooling. Existing portable means for providing power and cooling in a battlefield environment are too heavy, too noisy, and too fuel-inefficient. A… More

It is proposed to improve the logistics of providing utilities (electricity and chilling) to battlefield military units. The goal is to provide 30% savings in fuel, generator capacity, and system weight for meeting a representative demand of a forward operating unit. The key savings are from using… More

It is proposed develop an efficient, light weight heat actuated cooling system (HACS) for military applications. The goal is to provide 30% savings in fuel and system weight for meeting a representative demand of a forward operating unit. The key savings are from using generator waste heat to supply… More
