Had you ever thought of storing the solar thermal power without any expensive solar storage devices? .Can‘t we generate solar thermal energy in the form of low grade heat of 70-80.c with 20.c ambient temp .Yes this paper suggests a solution of storing the solar energy only by constructing a simple pool of salt water ,isn‘t it amazing?. Thus a solar pond is a pool of salt water which serves as the solar energy collection and sensible heat storage. The solar ponds made a tremendous progress in the last thirty years . This paper also mainly reviews the basic principles of the solar pond and the problems encountered in its operation and its maintenance. Here we also discuss the factors that enhance the heat storing capacities and also the factors that influence the technical and the economical viability of the solar ponds.

The depth of the problems that Nikolic procedures in his movies arise from the specific subject matter that was unlike some other arts, above all literature, in this field of aesthetic expression in the unique cultural and conceptual framework of former Yugoslavia, less prevalent. Although it is difficult to talk about their polyphonic or polymorphic characteristics, the clear and dramatic functional narratological structure of his movie stories should be pointed out, so much more since Nikolic never dealt with esoteric subjects and vain speculations, but he tried to rise the narrative statement to a level of absolute recognition, especially when he the anthropological discourse embodied in traditional norms, mystical and theological dogmas were involved. In such an approach, abstracting straight guided plot lines and extensive exposures, we can undoubtedly speak of full compliance and permeation of all the expressive constituents of the diegetic structure in Nikolic's movies. A strongly emphasised demystification of ultra-traditional interpretation of eros and simultaneously its relationship with ethos, the constant confrontation with extreme ethical views and distorted visions, as well as his persistence in debunking the dominant and burdensome taboos, are particularly important in Nikolic's narrative. Thus comprehended Eros together with so-called "forbidden topics" and their hidden and often ambivalent meanings, including possible deviations from their essence, often take precedence over other thematic elements in the dramaturgical structure of Nikolic's movies.

This paper proposes an approach for the hybrid solar photovoltaic and wind power system in Battery management for stand-alone applications with Artificial Intelligence. In general, Solar and wind energy are utilized as leading sources of energy and battery unit is considered as storage element to meet out the load demand. Loads are considered based on the priority. Ratings of hybrid energy system components such as solar PV, wind generator, battery unit, power electronic converter, etc., are optimally selected based on the rating of load. Fuzzy logic and Neural network are the tools being used here to obtain the maximum utilization of battery. A simulation model with MATLAB/Simulink for the hybrid power system has been developed. Considering power supply variation in Solar and Wind Hybrid Power system (SWHP) caused due to disturbed power supply from wind turbine generator and solar cells, fuzzy-PID-NN control is brought into it. The main components model of SWHP is established and simulation of fuzzy-PID-NN control is being presented, analyzed and compared. The final result of simulation indicates an effective utilization of battery.
