Ok here ya go!\n\n In 2005, worldwide capacity of wind-powered generators was 58,982 MW, their production making up less than 1% of world-wide electricity use. Although still a relatively minor source of electricity for most countries, wind power generation more than quadrupled between 1999 and 2005.\n\nMost modern wind power is generated in the form of electricity by converting the rotation of turbine blades into electrical current by means of an electrical generator. In windmills (a much older technology) wind energy is used to turn mechanical machinery to do physical work, like crushing grain or pumping water.\n\nWind power is used in large scale wind farms for national electrical grids as well as in small individual turbines for providing electricity in isolated locations.\n\nWind energy is abundant, inexhaustible, widely distributed, clean, and mitigates the greenhouse effect.\n\nAn estimated 1 to 3 % of energy from the Sun that hits the earth is converted into wind energy. This is about 50 to 100 times more energy than is converted into biomass by all the plants on earth through photosynthesis. Most of this wind energy can be found at high altitudes where continuous wind speeds of over 160 km/h (100 mph) occur. Eventually, the wind energy is converted through friction into diffuse heat all through the earth's surface and atmosphere.\n\nThe origin of wind is simple. The earth is unevenly heated by the sun resulting in the poles receiving less energy from the sun than the equator does. Also the dry land heats up (and cools down) more quickly than the seas do. The differential heating powers a global atmospheric convection system reaching from the earth's surface to the stratosphere which acts as a virtual ceiling.\n\nThe change of seasons, change of day and night, the Coriolis effect, the irregular albedo (reflectivity) of land and water, humidity, and the friction of wind over different terrain are some of the factors which complicate the flow of wind over the surface.

How Does the Windmill Work?\n\nWind Energy\nWind is an indirect source of solar energy. It is caused by the uneven heating of the earth by the sun and the resulting redistribution of air to equalize energy in the atmosphere moving air from areas of high pressure to areas of lower pressure. The energy of the wind is transferred to the windmill’s sails where it is harnessed to perform work.\n\nThe cap of the windmill is turned with the winch attached to the bottom of the tail pole until the sails face the direction of the wind. Depending on the wind speed, wind boards are installed on the leading edge of the sails and canvas sail-cloths are unfurled across the sail-frames. The Miller climbs the sail-frame using the sail-bars like rungs of a ladder attaching the canvas to the cleats on the whip. High winds require less open sail than low wind. The Miller determines the amount of sail surface required based on wind speed and partially furls (reefs) the sails as required. The sails catch the wind and turn the wind-shaft.\n\nThe wind-shaft which is connected to the brake-wheel can be stopped with the brake which consists of a band of friction blocks encircling the brake-wheel attached to the brake lever and controlled via a rope near the tail pole attached to the brake lever. The turning brake-wheel turns the wallower connected to the upright shaft on the fifth level. A wood wheel on the fourth level is used to adjust any irregular spinning of the upright shaft.\n\nThe upright shaft is connected to a large gear called the spur-wheel on the third level. Power to run many things in the windmill is drawn from this wheel. Two stone-nuts turned by the spur-wheel drive quant shafts in turn rotating the runner stones; the top stones of the grinding stone pairs. The lower stone of the grinder is the bedstone; it remains stationary. The spur-wheel also turns a third lantern gear (trundle) to drive power transfer belts, pulleys and shafts used to operate the grain elevators, sifters, grain separator, corn sheller and a vacuum system.\n\nHow is Grain Ground into Flour?\nGrain and flour move through the system using grain elevators and gravity. Grain is carried into the windmill and poured into first level hoppers. From there it is cleaned in the basement with the corn sheller and grain separator. Grain elevators carry cleaned grain to the third level hoppers which hold it until it is dropped into the second level grinders. Corn & oats are ground in the west grinder and dropped into a ceiling mounted sifter on the first level. Wheat & rye are ground in the east grinder. The flour drops into an elevator at the ceiling of the first level, is carried back up to a hopper on the third level and dropped into the sifter on the second level. The sifted flour is stored in hoppers suspended from the ceiling on the first level.\n\nInteresting Notes\nThe windmill contains two scales; a floor scale in the windmill and a wagon scale outside the north end of the windmill. The scale inside the windmill can weigh individual bags of grain. The scale outside is used for weighing loaded and unloaded wagons.

Generally terrible for the environment, and only provides nominal power given the environmental impact, and the amount of energy put into the original project itself.\n\nI'm much more in favor of the new wind mills.  They turn slowly, so don't kill birds, and provide power about as cheaply as any coal plant can, without the pollution!

Windmills are the best solution right now for renewable energy.  Hydroelectric plants destroy the environment much more then building windmills does, solar cells are toxic to make, and degrade after a few years.  To build a 400MW natural gas power plant and 400 MW worth of windmills (roughly 200 of them) costs almost the exact same amount of money.  Once the windmills are built, they require no fuel, and minimal maintainance.  On the other hand, a natural gas power plant is only operational about 2/3s of the time due to the need to maintain the very precise and expensive turbines, boilers, etc.  \n\nwhen people say windmills are an eyesore, putting them ~ 10 miles off the coast wont ruin anyones view, at 10 miles they will look like ripples on the surface of the water.  We have miles and miles of farmland that we could use in the middle of the country (not because there's lots of space there but the flat ground right after the mountains is ideal for windmills), given the relative footprint of a windmill, it wouldn't be a huge loss.  On top of that, by placing windmill on top of skyscrapers (if any of you have stood on an observation deck its always windy - and the structure is already there - you just have to go up a little higher)  the building would generate its own electricity, as well as then provide power to the grid.  \n\nThe downside of windmills is that they aren't efficient to put everywhere, so electricty transmission can become an issue.\nI dont know how many people have actually stood next to one of the bigger windmills, I find them rather aesthetically pleasing.

how about looking at wind generators online and seeing how much power they generate.

That's an urban legend.  Windmills are generally set up to rotate in a way that makes the most out of the prevailing local wind.  If you look at windmills you will find that they do not all rotate the same way.

the above one of solar cell is gr8\nor you can make a model of a wind mill, attach it to a motor and then, artificially, rotate it to produce current in the motor and connect it to a small bulb to show it lighting

i have no clue, not sure what this competition would be anyways, might want to include the goal of what the windmil will do, what size is it going to be...\n\ni'd say research with like those windmill powerplants, they are shaped like HUGE propellers i think, i'm sure that would provide alot of torque and be efficent.\n\nthe companies making those windmill powerplants put LOTS of money into research to figure out how they can have their designs make the most electricy, so researching what they have found would probably help your project

It has to do with high and low pressure systems. Wind moves from high-pressure areas to low-pressure areas.

It is renewable; We are always going to have waves.\nIt is quiet.\nIt does not take up land.\n\nTidal Power is a distinct source in itself. (See both sites)

yeah its a great idea for kids to experiment with wind. More studying of the earth the more we can advance ourselves and who knows your child could come up with something truly amazing. Afterall we shouldn't discount childrens' research.
