i have to make a model of wind energy in 3D
i don’t know how to make it?
can some one help please(:
huuuuuh?
how to make it
a model people!
i want to make it!
but i dont want to use it
like blow stuff
and ppl why did yu say
fartt ahahah very funny
nott =/
and thanks for the big information(:

Get a 5 dollar desk fan to blow on a pinwheel.
The spinning pinwheel can stand for a turbine that spins the generator that makes the electricity. (In the generator is a big magnet and coils. When magnet and metal move near each other, they cause electrons to move. Moving electrons IS electricity.)
I reckon you should first know how wind turbines work so I would suggest reading this article to start with http://renewableenergyarticles.blogspot.com/2009/11/wind-turbines-things-to-know.html , and then perhaps you’ll get some idea.
I assume that you mean "use" wind energy as in "creating electricity." *Making* wind energy would just mean blowing, or plugging in a desk fan.
I’ve tried to include links to any of the terms that I’m using that you might need to look up.
This refers to a horizontal generator not a vertical generator. The generator can be hand made by you, which is electromagnetic induction (many wraps of copper wire spinning inside of a magnetic field) if you want to really build from scratch. This is very technical, though, with a lot of reasonably complicated wiring – the actual current, shunting the current down a 90 degree angle from a *moving* circuit, transporting it to what is going to use the electricity… if you want to do that, come back and ask the question, and I will be happy to help out. But to keep it simple…
In this case, I’ll use the horizontal-rotation turbine, not the vertical-rotation. The horizontal-rotation style are the ones that look like really big airplane propellers up on tall steel towers.
Start with the generator. This is the most important part. Any DC motor can be used, but surplus Ametek motors work the best (that’s what I used). They can be found all over the Internet, even places like ebay. I have included a link to build your own, if you choose to, and don’t want to come back here with a question.
Next you’ll need a hub. This can be made out of a variety of materials, ideally something easy to work with, but strong and light at the same time – aluminum works very well. Cut out a circle of the material that you choose, and machine it so that it’s as round as possible (a lathe works well, if you have access to one), and drill a hole the size of your DC motor’s axle. Mount your circle it on the axle by welding or bolting (or gluing, if you need to – just make it very stable). Be sure to drill holes to mount your turbine blades.
The turbine blades are obviously very important, because they’re what catches the potential wind energy. The blades can be made out of many materials – thin metal or plastic, light (and sturdy) wood, and even PVC pipe. The important thing is that they are angled into the wind (not flat to the wind, but at an angle, say between 30 and 60 degrees), so that when the wind strikes the blade, it pushes them to the side, which turns turns the generator. You can have as many blades as you want. Experiment with the number, because depending on your materials and construction, there will be an ideal number where you reach maximum electricity going up, and not wasting energy by turning blades that are actually sucking energy out, because they’re basically just dead weight (look at common commercial turbines, they usually only have 3 blades – you probably need more, because those blades are very technical and finely machined).
Build a tower for your turbine out of any type of pipe. I used aluminum. 2-3 inch pipe works well. Try to get it at least 12 feet high. The higher the tower, the more wind you’ll get – in the real world. If you’re just doing this in a lab, then obviously wherever you’re going to be getting your wind source will decide how tall or short your turbine should be.
Connect wires to your generator and run them down the tower. Connect them to a charge controller, and the controller to your batteries. As soon as the wind starts blowing, you’ll be charging your batteries. Now you have your "free energy," and you can start using it right away!
Good luck with the project, and remember, good links below, some very more detailed than my explanation.
A model of wind energy in 3D?
Use a hair dryer, the small portable kind, tie or tape a few lengths of sewing threads near the business end. Plug it in and turn it on (low or no heat), voila! 3D model of wind energy.

If you can find a way to connect a fan to a generator of some type letting the wind propel it then transfer the energy to do something like turn on a light bulb or power an am fm radio then you would be doing something pretty darn impressive.
The simplest form of wind energy is the motion of propellers from direct motion of the wind to a whirly gig. By turning a fan down into a large box maybe, with tiny bits of paper you can see the energy of wind against objects in a swirrly motion. like a small dirt devil in a shopping center where there is an L shaped area where wind blows against the L shaped planes of intersection and the trash paper goes around in a circular manner.
Flying a kite gives you the true forces of the wind against the pull of the kite string and the way the kite moves in the air.
The oldest form of wind energy was with the sailing ships that were completely dependent on wind energy to go place to place.
Sidewalk Surfing using a modified sail is kind of cool don’t you think?
first you put the little blowy things (the things that turn when air hits it hard enough) and then blow like the wind
