... Optimization of thermodynamic cycles is important for the efficient utilization of energy sources; indeed it is more crucial for the cycles utilizing low grade heat sources where the cycle efficiencies are smaller compared to high temperature power cycles. This paper presents the optimization...

... Improving the efficiency of thermodynamic cycles plays a fundamental role in reducing the cost of solar power plants. These plants work normally with Rankine cycles which present some disadvantages due to the thermodynamic behavior of steam at low pressures. These disadvantages can be reduced...

... the chosen methodology of accruing fuel cost. The exergy equations coupled with appropriate cost provide a valuable insight into areas of potential improvement of the Combined Water and Power Plant (CWPP). Various combinations (Combined cycle power plant (CCPP) with stand alone MSF, MED and RO; CCPP with MSF...

... for supplying supplemental power for dismounted soldiers. This STO effort resulted in the development of four proof-of-concept Heel Strike Units where each unit is essentially a small electric generator that utilizes piezoelectric elements to convert mechanical motion into electrical power in the form factor...

... frequency to improve conversion efficiency. The energy harvester is simple, compact, and insensitive to excitation frequency. Initial prototypes have demonstrated power densities and specific powers many multiples greater than the best-performing, commercial vibration harvester. We have also developed...
