electrical energy that can be used for power.” The German physicist Albert Betz calculated in 1919 the possible maximum amount of energy that can be extracted out of wind energy. He came to the result of 59.3% that can be extracted and named this calculation Betz’ law. Further the extracted energy is converted into electricity with an efficiency of 70% and would give all together a total efficiency of 41%. Observing the world’s physical supply of wind energy you will come to the result that 200-times

and flight system technologies‚ these being within NASA’s area of research responsibility” (p. 16). When one hears the name NASA‚ they only think about their involvement in space exploration‚ but NASA is also doing research and development in aerodynamics and aviation technology which led to better flight control and deicing systems (Hamilton‚ 2011‚ pp. 17-18). Although NASA is responsible for these technological advances‚ they have to report all findings to the FAA to get the changes incorporated

Solar car design Originally published on Solar Love. Generally speaking‚ I don’t think solar-powered cars are very practical. They are fun and do highlight how far we’ve come. They may help to advance certain electric car technologies and designs. However‚ except for certain niche situations (like a hospital car for rural Zimbabwe)‚ they have serious limitations. For one‚ solar panels aren’t cheap — risking their destruction or damage in a car accident doesn’t seem wise. Secondly‚ the sun

Imagine a time when being cool meant long hair‚ a slick car‚ and tickets to the weekend double feature at the drive-in. The 1960s made this dream the goal of teenage boys; near the end of the 2010s‚ if a person has similar things‚ they can still be considered cool‚ hip‚ and with the times‚ excluding the drive-in. Drive-ins are nearly extinct‚ so maybe just a normal movie. With its share of similarities‚ the 1960s did have profound differences in many categories. Some of these categories include

to the potential energy that can be extracted. Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the calculations required to simulate the interaction of liquids and gases with surfaces defined by boundary condition. In this paper‚ CFD analysis of wind turbine blade‚ a complete drawing‚ and details of sub-system are carried out. INTRODUCTION: WIND turbine
