Transcript: Presentated by Bruce and Greg Wind Power Overview Overview key concept and thesis statement Wind power or wind energy describes the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water), or can be converted into electricity by a generator. In this presentation we will introduce the mechanism of wind power and analye its possitive outcome and drawbacks, which will eventually come to a conclusion. The power of wind The power of wind what is wind power How wind are form How wind are form Typically, this begins with the sun’s radiation, which is absorbed differently on the earth’s surface. The earth's surface is heated differently because of scenarios like cloud cover, mountains, valleys, water bodies, vegetation and desert lands. As a result of this uneven heating, there are bound to be earth surfaces that vary a lot in temperature. Air on surfaces with higher temperatures will then begin to rise because it is lighter (less dense). As the air rises, it creates low atmospheric pressure. Air on surfaces with cooler temperatures sink (do not rise). The sinking creates higher atmospheric pressure. This behaviour or warm gases or liquids moving upward and being replaced by cooler particles is called Convection. The energy moving during convection is called convectional current Map Map China China India India United State United State Europe Europe history history Text Text 1st century AD: For the first time in known history, a machine that powered by wind had been created by a Greek engineer, Heron of Alexandria. 1887: Scotland built the first known wind turbine used to produce electricity. The wind turbine is created by Professor James Blyth. This 10 m high, cloth-sailed wind turbine was installed in the garden of his holiday cottage, it was used to charge accumulators, power the lighting in the cottage, thus making it the first house in the world to have its electricity supplied by wind power. 1891: A Danish scientist, Poul la Cour, develops an electricity-generating wind turbine. In 1895 Poul la Cour converts this windmill into a prototype electrical power plant and used to provide electricity for lighting for a village. By 1900, there’s approximately 2,500 windmills are being used across Denmark for mechanical purposes, such as grinding grains and pumping water. 1975: The first US wind farm is put into use, producing enough power for up to 4,149 homes. 1991: The first offshore wind farm in the world is constructed in southern Denmark. 2010: Global wind power capacity reaches 197,039 megawatts. Timeline Timeline Timeline 1th century AD the first wind turbine that produce electricity 1887 1891 1991 The first wind-powered machine was built development of windmill the first WInd farm in The US Mechanism Mechanism how does it work how does it work Wind energy have been harnessed for hundreds of years. From old Holland to farms in the United States, windmills have been used for pumping water or grinding grain. Today, the windmill modern equivalent - a wind turbine - can use the windenergy to generate electricity. Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind. Turbines catch the wind energy with their propeller-like blades. Usually, two or three blades are mounted on a shaft to form a rotor. A blade acts much like an airplane wing. When the wind blows, a pocket of low- pressure air forms on the downwind side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift. The force of the lift is actually much stronger than the wind force against the front side of the blade, which is called drag. The combination of lift and drag causes the rotor to spin like a propeller, and the turning shaft spins a generator to make electricity. Wind turbines can be used as stand-alone applications, or they can be connected to a utility power grid. For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant. ( Possitive Outcome Possitive Outcome 1. This is an renewable resources 2. Environmental friendly Wind is a clean source of renewable energy that produces no air or water pollution. And since the wind is free, operational costs are nearly zero once a turbine is erected. Mass production and technology advances are making turbines cheaper, and many governments offer tax incentives to spur wind-energy development.

Efficiency Tremendous installation space required Location requirement for installations Green Impact Description of the technology Pros and Cons Potential competitive advantage or benefit(s) derived from implementation What Is Solar Power? How Does It Work? Solar panels (PV) production do create a small amount of CO2, but over the life of a solar installation it produces on average of 30 times less CO2 than coal power. This study looks at 3 countries and compares the amount of CO2 emissions for electricity consumption. Compared to coal and gas, solar PV can be considered as a greener option for the environment.

Solar panels are made up of silicon wafers cut from silicon crystals. When light hits the silicon, photons move in a predictable direction. The solar panel collects the moving photons in the form of electricity. An array of many panels aggregates the electricity and it is converted into a useable for with inverters changing DC current into the AC current which is used in homes and businesses. Do you know where is the biggest solar hotel in the world?? Disadvantages “Green Hotel” is a nickname created for hotels which use solar power and other natural resources to create energy. Around the world, there are not many Green Hotels, Because of the limitation, these hotels become so special and unique. Green hotels use solar power to build a good image for marketing purposes. It proves to the guests that the property uses renewable resources to sustain the environment and support the ecosystem. A lot of people travels around the world and a Green hotel can show them how they can give a step forward to help the ecosystem. Good advertisement is needed so they can let regular hotels have an idea of how much energy they are using every year. Therefore people who wish to give part of their responsibility to our ecosystem will know which to choose and know which hotels are giving part of their own to help the world.

Transcript: My Technology Template Investigation Criteria A Problem The problem we have is that PYP students need to learn about simple cams. How can we make our presentation clear so that the PYP student learn clearly. Students also need to know about CAD/CAM Guiding Questions How can we use CAD/CAM to provide a more interesting experience? How can we make this a fun and interactive experience? How can we help PYP students learn about cams, levers linkages and pendulums? AOI Cams have been used by humans and we are using them everyday. Human Ingenuity Design Brief I am going to solve this problem by conducting the following The research I will do is search the internet to find information about CAD/CAM and cams The creation I intend to make is a PowerPoint presentation or movie to teach them about CAD/CAM and to guide them to make a cams model This will help the ISM community because it prepare PYP students for MYP Primary Research I asked the following questions 1 What are cams? 2 What is Cad/Cam? 3 Where are cams used in daily bases? 4 What wouldn't we have if we didn't have cams 5 How can we make cams or an example of a cam? 6 What types are there? 7 Why are cams useful? 8 How does CAD/CAM work 9 What website can use? 10 How can we teach people about Secondary Research Circular cams, also known as eccentric cams, are circle-shaped and fitted off-center onto the driving shaft. These cams move very smoothly and are used to generate a wave-like motion in the follower. They are often used in mechanical toys to produce a smooth, recurring motion. Pear-shaped cams are actually egg shaped. The follower is level for most of the cam’s rotation, then is suddenly pushed up at regular intervals. These are used in car engines to control the flow of air/fuel and exhaust in the engine. Heart-shaped cams allow the follower to move at a constant velocity and therefore provide a very steady motion. They are used in sewing machines to wind thread onto the bobbin. Drop-cams are shaped like a snail shell. These cams lift the follower gradually, then drop it suddenly. The crank and slider is a special type of cam that you can find on the wheels of steam engines. It consists of a piston (the slider) that is attached to a circular cam (the crank) by a rod. The rod is offset from the cam’s axle. As the piston moves back and forth, it pushes and pulls on the rod, which turns the cam around. In a steam engine, the wheel is the cam! (this has been copied to help me learn) A cam converts rotary movements in to reciprocating movement. As the cam turns, driven by the circular movement, the cam follower traces the surface of the cam transmitting its motion to the required mechanism. Cam follower design is important in the way the profile of the cam is followed. A fine pointed follower will more accurately trace the outline of the cam. This more accurate movement is at the expense of the strength of the cam follower. As the cam turns it has a tendency to push the cam follower to one side. To overcome this a separate cam follower and push rod can be used as in this mechanism. Here the cam follower drags over the cam surface, accurately tracing the surface of the cam. Any movement of the cam follower is transferred directly to the push rod (this has been copied to help me learn) This information will be helpful because it will teach me and the PYP students about cams These pictures will help me by Creating the model cams Criterion B Design Design 1 We will use the changeable cam model and put a motor on it. We will also put a cow on the top nodding it’s head to show the movement of different cams. We will take two models and combine them. We will get the design from robives then import it robo master then covert it to an outline. The the machine will cut the design. We will use card, glue. We might add a motor to our model. These are the two models. We are going to use The cow The interchangeable cam Design 2 Making a short a short movie to show what are cams and Cad/Cams and how they work and make a model to show one. We will make the movie on movie maker. We will use a video camera to film how a cam works The design shows different movements of the cams can make and it fun to make, look at and to learn about them. Making a video, PowerPoint, Prezi or a poster to show how the craft Robo works. This will be easier and more clear to the primary. Final design We liked to first design because it will be easier and better way to explain to the P5/6 how Cams work. Criteria C Plan These charts are connected This will help me to be more organize with my work Criteria D Create Creation Evidence These are some photos to show us making the model Testing of designs against specification Design Specification To make sure my designs and final creation have worked I will make a questionnaire based on my specification Were the lessons fun? Have you learned a lot? Would you
