£1.50 Preview RemoveThe Power of Wind
Abstract The concept of a device to harness the power of wind is not a recent breakthrough, early designs can be traced to Persia between 500-900 AD, early vertical axis wind machines could also be traced to China, the development of such machines came to be from pure necessity to automate difficult tasks (Telosnet 2015). The primary purpose of these windmills and machines that harnessed the natural resource of wind was to either grind grains or pump water, in the Netherlands large amounts of land could be reclaimed for agricultural or industrial purposes, the broader benefits of this helped the development of the Netherlands into the first world European nature we know today. The challenges of a modern world has expedited the development of the modern turbine, particular the pressure of fossil fuel scarcity and global climate change. Power generation from wind turbines has drastically changed both the physical landscape of the world and the market landscape of power production, what is considered conventional power production has been challenged and changed. Recent important innovations in the modern wind turbines has drastically improved the cost, weight, maintainability and performance of the wind turbine. The overall improved feasibility of the wind turbine has contributed to important moments in power generation, on a sunny windy day in Germany - a leading industrialized country, it is often the case that the power required is created entirely from renewable sources.

This experimental lab report investigates one of the most important parts of the solar energy system called solar photovoltaic water pumping system (SPVWPS). It is one of the most interesting energy powers for the conventional pumping system and a cost effective application which is has been developed in the last two decades. This energy system is significant useful for remote off-grid areas. It uses photovoltaic cells in order to convert sunlight in to DC electrical power and then drive the pump by sunlight energy which converted to useful mechanical energy to drive the water pump. Nowadays, the combination of sunlight energy and water pump play an important role in agricultural production and domestic sectors purpose because it is less cost and they did not produce any harmful by product. New approaches has been investigated in order to develop high quality solar cells to improve the performance of the cells and bring down the cost of the system as much as possible which makes the system more usable and feasible in future. Although, the solar panel includes 80% of the cost of the pump system. The size of the PV system directly depends on the size of the pump, the amount of water needed and the intensity of the sun's radiation. For two reasons, the controller is used. First, the power output required by the pump is equal to the input power of the solar panels. Second, the controller usually generates a low voltage protection, in which case the system turns off. This causes the pump life to increase and reduces the need for maintenance. In this experiment we will briefly investigate and analyse the performance of solar array water pumping system efficiency under different condition.

Find the ratio (Fe/Fg) of the Coulomb electrical force Fe, to the gravitational force, Fg, between two electrons separated by distance r (a) (b) (c) (d) 5. Two identical balls, carrying equal charge each of mass 0.10g, are suspended freely by two threads of equal length repelled each other so that each thread make angle 300 with vertical line. At equilibrium, calculate the tension in one of the threads.
