Solar Air Conditioner or Solar AC refers to an Air Conditioner where the energy for the air conditioning is dervided from solar energy.There are 3 types of Solar Air Conditioning namely passive solar AC,solar thermal and PV Solar Air conditioning.Solar Air Conditioners though a niche area are expected to grow strongly in the future in hot areas like India where Air Conditioning is consuming huge amounts of energy and where there is sufficient sun light to generate big amounts of solar energy as well.
Assemblies of solar cells form solar panels. The raw material in solar cell- silicon in its purest form makes an ideal neutral platform for the transmission of electrons. Silicon also has some atomic-level properties which make it even more attractive for the./ creation of solar panels. Solar panels receive sunlight and actively convert that energy into electricity. The solar cells have a large area p-n junction diode which convert the energy from sunlight into usable electrical energy. The basic principle behind the procedure is Photovoltaic Effect, photo = light, voltaic = electricity ie. conversion of sunlight into electrical energy
The Indian economy has performed strongly over the last few years, regularly hitting 8% and above growth rates . This rapid economic growth has led to a significant increase in demand for crude oil and natural gas, to the extent that India is currently the sixth largest consumer of oil and gas. India is one of the biggest importers of crude oil and natural gas as it has to import 2/3rd of its requirements of Oil. Upstream activity in India has rapidly grown post liberalization with 42 active offshore rigs and several seismic vessels engaged in operations offshore on the east and west coasts. Several significant discoveries have been announced since the New Exploration and Licensing Policy (NELP) was introduced. The commercial discovery of the Dhirubhai field by Reliance in the deepwater Krishna Godavari basin has demonstrated the existence of significant reserves in the basins of India. As India imports about two-thirds of its crude oil requirement, Exploration and production of oil and gas is critical for India’s energy security and economic growth. Over the years the E&P industry has registered significant growth, primarily due to spiraling crude oil and gas prices.
Multijunction Solar Cell Concept
The basic principle on which solar cells work is Photovoltaic ie. they convert the photons from the sunlight into usable electricity. However, in this process neither is all the light absorbed nor does all the photons get converted into electricity. High energy blue light photons do not have all of their energy converted into electricity, some is wasted as heat & low energy red light photons are not absorbed at all. Sunlight is made up of a broad spectrum and depending upon these various wavelengths, photons of light also have different energy levels.Hence, to minimize this wastage & to enhance the efficiency of solar cells, scientists came up with the concept of multijunction solar cells.
The hair care industry has grown a lot in the recent years. The reason can be attributed to the fact that a large portion of our Indian population is using higher quality branded products. Of the estimated Rs.1, 611 billion FMCG market in India, hair care products make up approximately Rs.91.5 billion, or 8%, of the total according the Nielsen Retail Audit Report. The 14% growth rate in the hair care industry is also slightly higher than the overall industry average of 13.4%. Shampoo and hair oils, including coconut oils, continue to be the key components of this segment. The marketing startegy of rural distribution campaigns adopted by the hair oil manufacturers and dealers have helped to greatly expand the geographic coverage of hair oil products into the rural parts of the country. In addition, average prices for hair oil products have risen from Rs. 22.25 per 100 ml in 2008 to Rs.23.74 per 100 ml in 2009 according to the Nielsen Retail Audit Report.
Education is a critical requirements for India today as it lags behind other Asian countries in education indices with vast swathes of its population being illiterate.India’s hopes of becoming a major power will remain a pipedream till most of its labor force is educated and productive. As the country strives to become an economic superpower, need for high-quality education, at all levels, will increase. Not only is India deficient in providing primary eduction but due to the higher education costs, many students give up their decisions of pursuing higher studies. But, the emergence of education companies in India has led to a significant change in the scenario. They provide need based education solutions to facilitate the process of interaction between students, teachers and parents. These companies are coming up with technology based educational solutions to meet the educational needs of schools and colleges. These contents can be accessed from any part of India and other countries by interested individuals. They offer digitized content which can be disseminated through 3G spectrum mobile phones, broadband and other sources.
