The objective of this paper is tof provide a method for cost evaluation of low grade thermal energy conversion by Nitinol power plants. To accomplish this objective Nitinol power plant costs are subdivided int those which can be obtained through conventional cost analysis, and those which are associated with the Nitino heat engine and are not subject to conventional analysis. Analytic expressions are provided for the Nitinol heat engine capital costs and Nitinol replacement costs in terms of Nitinol performance, heat engine configuration, plant operating factors, material costs, and the cost of capital. Nitinol working material factors are identified that require further definition before firm and reliable costs can be determined. Where data are lacking, plausible assumptions and estimates are utilized tof perform a first-cut analysis. It is found that the Nitinol heat engine capital costs per unit power generating capacity are approximately $0.15/W, and that the cost of produced energy for the Nitinol heat engine portion of the power plant is approximately 0.74 /kWh, includin operation, maintenance, Nitinol replacements and the cost of capital for the heat engine. It is concluded tha Nitinol power plants for the conversion of low grade thermal energy may have a significant economical advantage over conventionally fueled power plants.
