The quantum of energy in the universe is constant. Neither can man create energy nor can he destroy it. All that he can do is to discover new source of energy that the natural has provided and make it usable for his needs by new and more efficient ways of conversion.
A solar powered refrigerator using an intermittent ammonia-water absorption system as refrigeration in remote areas where electrical energy is not available is described in this paper.


In my present paper I have made an analysis of feasibility of utilization of solar energy i ....etc

Voice controlled wheel chair is design and manufacture of intelligent machines that are programmed to perform specific tasks. These are generally designed to be a helping hand .they helps us in difficult, unsafe or boring tasks. These can be programmed to perform a variety of jobs, and they can range from simple machines to highly complex, computer- controlled intelligent system ....etc

Thermoacoustic Refrigerator



In 1987 an international group of scientists and Government Officials established the Montreal protocol, an agreement to control the use and release of CFC and to schedule a time frame for eliminating their production. This agreement is a historic step in the on going process of building consensus regarding environmental impact of CFC. Both the Montreal protocol and provisions for 1990 clean Air Act specify schedules for phasing out CFC production by year 2000.
This forced a new wave of research and developme ....etc

Environmental priorities are forcing chloro-fluorocarbons out of market place thereby creating a new demand for cooling

technologies. This paper presents an outcome of researches done to design, construct and evaluate a CFC free refrigeration

system. A prototype Thermo acoustic cooling system utilizing high amplitude sound waves in an inert gas is discussed.



Thermo Acoustic Engines

A thermo acoustic engine converts some heat from a high Temperature heat source into acoustic power rejecting waste heat

to a low temperature ....etc
