what are some ideas i can use to make a windmill project?

Are you looking for something like this, a homemade wind turbine to generate electricity?\n\nhttp://www.otherpower.com/17page1.html

These links should do it for you.  Good luck with your project.

You can make a tornado tube, and this website tells you exactly how to do it:\nhttp://ns.isp.nsc.ru/l24/mamont/climate/tornado.htm

You can make any simple machine having fulcrum, load and effort or u can even make a pulley.(These r very cheap and easy to make)\n\nFor ur project on universe u can get information from any encyclopedia or search in net.

Spears, boomerangs, fire.\n\nGoogle "how to make a boomerang"

Good Project:\n\nThere have been different attempts all need to be developed yet.\n\nThe attempts include:\n1.Solar energy through silicon cells.\nThis is of more importance in hot regions with maximum sun shine.\n\n2.Ethanol by way of combustion.\nStill an economical method is to be discovered for extracting ethnol from sugarcane.\n\n3.Hydrogen by combustion.\nHydrogen is to be obtained by decomposition of water.\n\n4. Nuclear energy at small scale.\nSo far techniques on domastic production have not been successful.

I've seen them made out of wooden matchsticks, and they were pretty nice. If you use tin cans, you would need a pair of tin snips and you'd need to cut into the sides of the can to bring out the blades of the fan on the windmill. I've posted some links to different tin can crafts sites for you. Good luck!

http://www.howstuffworks.com\nThey may have a link.\nThey did for building a wind powered generator.

All of these seem to have good starts for ideas,\n\nhttp://yahooligans.yahoo.com/Science_and_Nature/Experiments_and_Activities/Science_Fairs/\nhttp://www.ipl.org/div/kidspace/projectguide/\nhttp://school.discovery.com/sciencefaircentral/\nhttp://www.scifair.org/\nhttp://www.cdli.ca/sciencefairs/\nhttp://www.isd77.k12.mn.us/resources/cf/ideas.html\nhttp://staff.washington.edu/chudler/fair.html

I think I would go with windmills, solar panels might be too much technology for an Amish technology.

I was a preschool teacher for a few years\nRead them a book about wind,\n1. then make wind socks\n2. have them paint by making their own wind.  Give them straws and have them blow the paint\n3. Make kites\n4. give them grocery bags (plastic) and have them "catch wind"  they will run with the bag, the bag will fill up with air.\n5. make a wind chime.  Use the long tube pasta, or ask the parents to bring in items that could be used for a wind chime.\n6. blow bubbles\n7. make paper air planes and take them outside and let the wind blow them.\n8.  throw grass in the air, see which way it blows.

You could try lots of things, like:\nbeads\nfoam balls with pieces of wood to hold the sides together\npaper mache \nclay \n\nReally anything that you can mold or put together would work.

And just how do you propose I put a diagram on Y!A?\n\nNonetheless, electricity can be used to generate electricity, as mentioned.  Put three magnets around a rotating shaft & you get 3Φ electricity.\n\nMagnets work in compasses to help a person find direction.\n\nMagnets can be used to hold cabinet doors closed.\n\nMagnets can be used to lift things (like in a junkyard to move vehicles to a compactor), or to remotely move magnetic items (like if you can't reach your car keys, you could retrieve them with a strong enough magnet).

Electricity may be generated directly from solar panels (using the photo-electric effect) or from providing rotational force to an electric generator (just  wires moving across a magnetic field). \n\nAny form of energy that creates movement can be used for the generator -\n1. Apply heat to water to make steam to turn a turbine to turn a generator). The heat could be provided by fossil fuels, nuclear power, geothermal sources (eg hot springs), solar radiation.\n2. Use wind or water power to turn the generator (windmills & hydroelectric dams) \n3. Tidal power again to rotate a generator.\n\nAll these forms of electrcity generation require major capital expenditure that perhaps would be difficult for Ghana to afford. However, the windmills & solar panels are probably the easiest to implement since they could be implemented by an incremental approach. The disadvantage is the inability to match supply to demand.

Since this is a school project, your teacher probably wants to you to learn more than just how to build one.  \n\nLearn to use the library.  Learn to use internet search engines.  Learn to spell what you want to build.  Learn to be self reliant.

check the attached website out help give you some ideas.  I hope this helps

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
