Swimming pools provide a great way toexercise and beat the summer heat. Buildingand maintaining a pool, however, alsomeans relatively high costs added to yourhousehold’s budget. There are severalways that you can reduce operating andmaintenance costs, lower water consumption,and conserve heat if you heat yourpool. Many people heat their pools toextend the swimming season and/or tokeep it at a temperature that they are personallycomfortable with. This lets themenjoy the full value from their pool. Solarpool heaters are an option ....etc

Abstract:
The oil shocks of 1970s led to spiraling crude oil prices in the world market which prompted planners to view energy security as an issue of national strategic importance. Energy security has an important bearing on achieving national economic development goals and improving the quality of life of the people. World’s dependence on crude oil will continue for most part of the 21st century but the continued dependence on crude oil is loaded against it with inherent price volatility linked to finite global ....etc

ABSTRACT
A solar cell is a semiconductor device that converts solar energy into electricity by the photovoltaic effect, representing the fundamental power conversion unit of a photovoltaic system ,works under the principle of a P-N junction that absorbs light , releases electrons and holes , creating a voltage in the cell , which is then applied to load; being environmentally aware, and with the price of living rising at an alarming rate, solar power, generating energy from the natural resources of the sun, has in recent times become quite a ....etc

SOLAR CAR
Abstract
A solar car is a light weight, low power vehicle designed and built with a single purpose in mind - racing or raycing, a combination of race and ray from the sun. It has limited seating (one or two people) and cargo capacity, can only be driven during the day and does not represent a practical means of transportation. It does, however, offer an excellent opportunity to develop future technologies that can be applied to practical applications.
