Abstract

Economics are crucial to the success of any energy utilization system, and photovoltaic converters are no exception. At present, development of such converters is in the stage in which prices are still coming down rapidly. It is nevertheless, difficult to compare photovoltaic with other systems solely on the basis of investment cost. While photovoltaic have low operating cost, since they consume no fuel, their peak power can be only realized on a clear day, with the converter facing the sun. The average power will be less than half the peak power for sun tracking systems and less than one fourth of the peak power for nontracking systems.

Abstract

In today's competitive marketplace, the necessity for sophisticated cryogenic treating has become a reality. In addition to stress relief, today's companies are finding that controlled cryogenic treatment dramatically increases the useful life of component, perishable tooling and wear parts. Cryogenic is the ultra low temperature processing of materials to enhance their desired metallurgical and structural properties. This ultra cold temperature, below -310°F or 119 K, is greatly increase the strength and wear life of all types of vehicle components, castings and cutting tools. In addition other benefits include reduced maintenance, repairs and replacement of tools and components, reduced vibrations, rapid and more uniform heat dissipation, and improved conductivity.
