Windmills served ones to grind grain, pump water and for other jobs but today windmills are mostly used to generate electricity when harnessed to electric generators and commonly referred to as wind turbines. Wind is simply Air in motion. The Earth's winds contain vast amounts of energy. Today, advanced wind turbines offer an efficient means of capturing wind energy and using it to produce electricity. A windmill is a machine that converts the kinetic energy of the wind into mechanical rotary energy by using rotating blades. Wind turbines have two or three long, light-weight blades that turn...

Solar energy has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation, along with secondary solar-powered resources such as wind and wave power, hydroelectricity and biomass, account for most of the available renewable energy on earth. Only a minuscule fraction of the available solar energy is used. Solar powered electrical generation relies on heat engines and photovoltaic cell. Solar energy's uses are limited only by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture,...

Fuel is the main factor for the economy of a country. And demand of fuel is increasing rapidly day by day. Petrol & diesel are the main fuel used in worldwide. But all of these are non-renewable sources of energy and are very harmful for our environment. Combustion of these types of fuel produces different types of toxic gases which pollute air and at the same time, sources of this type of energy are limited. So, alternative fuel must be searched to solve our energy problem and to make free our environment from pollution. For these reasons, i proposed a method for producing biodiesel from...

A robot is a software controlled mechanical device that uses sensors to guide one or more end effectors(such as tools, grippers or hands) which is end of a manipulator, through programmed motions in a work piece in order to manipulate physical objects. This book represents a design process of an industrial robot intends to perform to grip an object and to take it certain place. We have decided to build the robotic arm and base by wood. The special feature of this arm is can pick an object by given instruction and also keep it by given instruction. The aim of this project is to design and...
