CHAPTER 4: PROTOTYPE MODEL OF OUR PROJECT [Fig. 23 Model] [fig. 24 Mechanism of Model] 4.1 Working of the model: The working of this tank and pipe arrangement for producing electricity is very simple. There are a large amount of water stored in tank water is flow through the pipe. These water flow through numbers of pipes. The water flow with different energy like kinetic energy, potential energy, pressure energy, gravitational energy therefore whenever water flow through simple pipe lot of…

If we look a century back when there were no automobiles, factories and vehicles. The air in that era was pure and free from any kind of pollution. People liked to live in such kind of atmosphere and they enjoyed this living style. We know that nothing is important than health. If a person is healthy, he/she can enjoy the life in a best way. A sick person has no taste of life. Polluted air damages the life of the human beings in bad way. So in this paper, we will try to explore the air pollution…

The used solar air collector is a single-glazed plate, we summarise the main components as follows:  A single transparent glass cover of dimensions 4 mm thick, transmits the heat flux to the absorber plate, ensures the reduction of thermal losses due to the heat exchange by convection and radiation and protects the absorber from the outside environment.  A thin copper absorber plate with a black chrome finish on it, which was 1.5 mm thick.  A polystyrene sheet with a thickness of 40 mm,…

Climate change poses an issue for many regions. This is true especially for coastal regions below sea level. The logistics of trying to counteract the effects of climate change are seemingly ridiculous. For regions like Southern Florida, the effects of climate change are severe to the point that they cannot be mitigated with tradition methods of dealing with a rise in sea level. Some short term solutions involve creating bigger and bigger pumps to transport the water away from important areas,…

5 Main Reasons Your Solar Lights Are Not Performing as Well as New What is the lifespan of solar lights? The questions that are often asked about solar powered lights is how long it can go and how can one prolong the life of solar powered lights as well as ensure they give the best performance. Most of the time, people discover that the quality and performance of their solar lights reduces in a short period. For instance, the light emitted may not be as bright as it used to be. In addition, if…

Student ID No. 13033380 Module Code: UMSCQV-15-M Strategy analysis of Siemens Wind Power 1. Introduction Siemens Wind Power, (formerly Danregn Vindkraft A/S and Bonus Energy A/S) is a wind turbine manufacturer established in 1980 as Danregn Vindkraft. Bonus Energy was acquired by Siemens of Germany in 2004. The organisation became a separate division of Siemens in 2011, with headquarters established in Hamburg, Germany. Siemens wind power has a history of more than 30 years and is the…

There are many types of renewable energy sources in the world. We can run the world forever off of these energy sources, until something catastrophic happens to the planet. There can be a plethora of similarities and differences between the types of energy. So I am going to break down solar energy and wind energy. The most obvious and simple similarity of these two is that they create power, and lots of it. A single solar panel can create a few kilowatts (kW) to over 100. While a single wind…

Chris Burden(April 11, 1946-May 10, 2015) an American artist working on performance, sculpture and installation art. He created “Urban Light” a sculptural work consisting of 202 antique lights. This display is outside of LACMA. The antique lights are solar powered. Metropolis II, 2011. Chris Burden, United States, 1946-2015. DC motors, electronic controls and sensors, custom die-cast cars, HO-scale train sets, neodymium magnets, steel, aluminum, copper sheets, brass, plastics, assorted wood…

The Fresnel lens was first invented by French physicist Augustine Fresnel and at first were a simple, beehive resembling contraption with a light source in the middle, but then it developed into something that mirrored a bull’s eye with a more powerful beam (Fresnel Lenses). The Michigan Lighthouse Conservancy went on to explain that the Fresnel lens was created for the sole purpose of installation within lighthouses. The efficiency and power of a Fresnel lens allowed its design to emit a source…

Advances in photovoltaic module technology, inverters, system installation practices, and design standards are improving the efficiency of solar systems and have led to the solar system becoming established as a strongly competitive energy source for off-grid energy applications. Substantially reduced Photovoltaic module cost and higher module efficiency compared are playing a key role in this expansion. The…
