In today’s world, the amount of unstructured data collected is humungous. This unstructured data is of no use if it is not properly processed, analyzed and evaluated. Using this data for the betterment of mankind is what most of the largest companies like Google, Facebook, Amazon, Netflix and much more are targeting. Big data is a term for datasets which are so large and complex that traditional database systems such as MS SQL, MySQL, etc., are incapable of handling them. It is not the amount of
means combination of two or more than two. A device that combines a silicon solar cell with a triboelectric generator that can harvest wind energy is known as Hybrid Power System. Basically these devices are powered by the renewable energy sources like sun and wind. . Solar energy enters from the rooftops and fom the windows. However, a large amount of wind still gets wasted in cities—normal wind turbines are not suited to urban areas because of their size. Instead of depending on the wind to spin a rotor
is derived from the rays of the sun, as is evident from its name itself. Solar energy has numerous benefits for users. However, until recent years, this source of energy could be used only during the day. Presently though, the current technology enables individuals to effectively store and use solar power, even during the night. We would be discussing some of the major benefits of solar energy in this article. While it has always been customary to depend on the sun for heat and warmth, generation
interconnected by power, communication and transportation. In the beginning, humans would have to rely on themselves and the sun for power and light, respectively. Additionally, humans were limited to the number and strength to accomplish tasks such as hunting, building homes, and providing other necessities for themselves and their families.
cars -- those that run solely on electricity -- are the cleanest and least expensive to operate” (Hirsch). Since an electric car has less moving parts than a conventional car, there is less wear and tear on the engines. Customers don’t have to worry about gas charges, engine oil, and engine parts. “...Electric and hybrid vehicles exceeded $600 billion last year, nearly equivalent to the United States defense budget" says the article “Climate Deal Is Signal for Industry to Go Green.”(Krauss and Bradsher)
panels, generates electricity from sunlight. It is a device that converts light energy into electrical energy. There are four types of concentrated solar plant technologies: Parabolic Trough, Compact Linear Fresnel Reflector, Power Towers, and a Dish-Engine. As Solar Energy Industries Association explains, “Parabolic trough systems use curved mirrors to focus the sun’s energy onto a receiver tube that runs down the center of a trough. In the receiver tube, a high-temperature heat transfer fluid (such
Where would the world be without energy? Well, the answer is nowhere, the earth wouldn’t exist because there would be no nuclear fission of hydrogen occurring on the sun and the earth the earth would freeze over and fall into darkness. Where would we be if there was no energy? We wouldn’t exist, energy is vital to us it provides us with heat and gives us food to eat, and oxygen to breathe. To be more specific no life would exist without energy, energy is a vital resource to the survival of mankind
Proponents of a world-scale hydrogen economy argue that hydrogen can be an environmentally cleaner source of energy to end-users, particularly in transportation applications, without the release of pollutants like particulate matter and carbon dioxide. However hydrogen continues to have technical obstacles associated with it, including storage issues, due to the fact that hydrogen has a high energy density by weight, but has a low energy density by volume when not highly compressed or liquefied.
Susquehanna Steam Electric Station, a nuclear power plant. A combined cycle natural gas power plant near Orem, Utah. All turbines are driven by a fluid acting as an intermediate energy carrier. Many of the heat engines just mentioned are turbines. Other types of turbines can be driven by wind or falling water. Sources include: Steam - Water is boiled by: Nuclear fission, The burning of fossil fuels (coal, natural gas, or petroleum). In hot gas (gas turbine)
Solar ENERGY The form of electromagnetic energy emitted from the sun and generated by means of a fusion reaction within the sun. There are little terms regarding the solar energy. A valuable source of terms is the ISO 9488:1999 standard, which gives the solar energy into three languages:- Absorber Component of a solar collector that collects and retains as much of the radiation from the sun as possible. A heat transfer fluid flows through the absorber or conduits attached to the absorber. Absorptance:
