Essays on Solar Collector

Abstract

The seawater forms 97% of water of the world, and the icecaps account for 2%. The portion of water available for human consumption is barely 0.5% and that also in aquifers. The widening gap between availability and requirement of potable water especially in the Gulf countries has necessitated newer methods and technologies for production of water suitable for human consumption. This situation in the Gulf region has developed due to non- availability of surface water, high growth of population and urbanization, and water depletion. The present paper takes account of the desalinization of seawater plant established in Abu Dhabi ...

Abstract

The project deals with the problem of solar power that is an environmentally safe alternative to the currently used sources of energy, such as oil, gas and coal. It is proved that renewability, an ecological safety and a relatively constant availability of this energy sources are the main advantages of solar power. However, technological expensiveness of energy retrieving appliances, especially in the case of space-based solar power, is cited as one of the main disadvantage that prevents the USA from putting solar energy to a good use unlike Germany where state dotation and solar program flexibility allow the unrestrained installation of ...

1. Introduction Agriculture and other food products are dried for use. The agriculture grains are dried for future use or production process, in order to dry the agriculture products the sun drying has been used for many years. The sun drying dries the products in a open air condition with the help of hot sun rays. In past centuries the sun drying systems has been used. Most of the industries use mechanized drying instead of sun drying system. The mechanized drying uses boilers and fan to heat and force the air to the required part. The time taken for ...

Sun plays crucial role in the life of the Earth. The entire organic world of our planet is obliged to the Sun for its existence. It is not only the source of light and heat, but also the original source of many other types of energy (oil, coal, water, wind). Since people appeared on the Earth, they began using the sun's energy. According to archaeological data, it is known that housing preference was given to quiet places, closed from the cold winds and open to the sun's rays. Perhaps the earliest known solar system can be considered the ...

Introduction

With people becoming more conscious of the detrimental effects of fossil fuel, the demand for green sources of energy is on a rise. The Sun is the source of all the energy in this world. Even if a small percentage of solar irradiance is collected every day then all the problems related to the scarcity of sufficient energy will be solved. However, it is not very easy to collect and store solar energy in an effective way. Solar Collectors also known as Solar Thermal Collectors are designed to absorb solar energy from solar radiation which is then reduced to heat water ...

Solar Energy

Solar energy is a radiant heat and light from the sun being harnessed to provide electricity, heat, cooling, hot water, and light for domestic or industrial use. The harnessing involves a number of technologies including solar hot water, photovoltaic systems, solar electricity, daylighting and passive solar heating, and solar process heating and cooling. The invention of the solar energy dates back to 1767 when Horace-Benedict de Saussure, a Swiss scientist invented the first solar collector which became widely known as the first oven using solar energy (Foster et al. 7). Saussure’s solar collector was an insulated box having three glass layers ...

Organization chosen by us for analysis is 3M which is one of the biggest conglomerates in Australia. The company is into various segments and hence considered to be a conglomerate. 3M achieved global sales of $29.6 billion in fiscal year 2011 which is an increase of 11% in comparison to 2010. Company has increasingly expanded its global footprint across the globe.
