What is Wind Power and How Does It Work?

“The answer, my friend, is blowin’ in the wind.
The answer is blowin’ in the wind.”-- Bob Dylan

Wind Power Starts with the Sun
Wind power is actually a form of solar power, because wind is caused by heat from the sun. Solar radiation heats every part of the Earth’s surface, but not evenly or at the same speed. Different surfaces—sand, water, stone and various types of soil—absorb, retain, reflect and release heat at different rates, and the Earth generally gets warmer during daylight hours and cooler at night. As a result, the air above the Earth’s surface also warms and cools at different rates. Hot air rises, reducing the atmospheric pressure near the Earth’s surface, which draws in cooler air to replace it. That movement of air is what we call wind.

Wind Power is Versatile
When air moves, causing wind, it has kinetic energy—the energy created whenever mass is in motion. With the right technology, the wind’s kinetic energy can be captured and converted to other forms of energy such as electricity or mechanical power. That’s wind power. Just as the earliest windmills in Persia, China and Europe used wind power to pump water or grind grain, today’s utility-connected wind turbines and multi-turbine wind farms use wind power to generate clean, renewable energy to power homes and businesses.

Wind Power is Clean and Renewable
Wind power should be considered an important component of any long-term energy strategy, because wind power generation uses a natural and virtually inexhaustible source of power—the wind—to produce electricity. That is a stark contrast to traditional power plants that rely on fossil fuels. And wind power generation is clean; it doesn’t cause air, soil or water pollution. That’s an important difference between wind power and some other renewable energy sources, such as nuclear power, which produces a vast amount of hard-to-manage waste.

"I didn't really expect them to come all the way out here in northern Iowa to start a wind farm. But this is really great. Now we grow corn on the ground and generate power in the air—all on the same piece of property." —Delbert Watson, farmer near Clear Lake, Iowa, quoted in the Christian Science Monitor
The first heyday of wind power in America lasted from 1870 to 1930, when thousands of farmers used the wind to pump water and generate power. The second heyday is just beginning. Wind power is the fastest-growing energysource in the world,with annual average growth of 32 percent between 1998 and 2002. In the United States alone, nearly two billion dollars' worth of wind turbines are projected to come on line in 2003—enough to power 800,000 homes.

*After consult with Mr. KY, I have decided to changing some my ideas.

Navigation Planning

Unity is an interactive installation where users are able to interact with the projector screen by blowing and stepping. I t creates a mystical experience of blowing windmill to generate electricity. This work which is applies for multiplayer. In this work, a simple maze game to interact with users which is cooperative to achieve the common goal. A simple technical part applies that using a projector, microphone and webcam. Zone trigger will set up on the floor for user to control the movement. A microphone is for user to blow windmill which is spinning that generate electricity. The visual of the maze game is in a dark environment. Among the road have some enemy and trap that need power supply to the bulb just can see clear the road. When wind power (blow) applies to the windmill will light up the bulb. Blow harder the bulb and environment will become lighter. The road become lighter that bicycle can go along the road. This is to show users have to cooperate to go out the maze. Without either one they can’t achieve the goal like bicycle need the light to know the road. UNITY.
