Just buy American, and you can save the time building it..

Take a plywood board. Fix a rectangular (50x12 mm) wooden rod of about 600 mm length with it so that when board is horizontally placed rod is vertical.\nMake a hole in vertical rod at about 25 mm below top. Fix a small ball or roller bearing in it. Fix a small rod through bearing and mount car radiator fan blade on one side and a small tape recorder pulley on other side of it. On the side of above pulley (used in tape recorder) make a fixing arrangement (with vertical rod) below above pulley and mount a tape recorder motor on it.\nJoin pulley of motor and pulley on which radiator fan blade is fixed using belt used in tape recorder drive. Since tape recorder motor is a DC motor it acts a generator also.\nConnect wires of motor (generator) to a voltmeter/ lamp.\nPortable wind mill is ready. This is a practical working model of wind mill. It has been displayed in science exhibition.\n\nAs regards increase in output based on number of blades, you are aware that wind mill changes kinetic energy of wind into electrical energy. Kinetic energy of wind depends on velocity of wind and contact area of blades. So try and find out truth for yourself. You have to work to learn.

Actually, for this idea to work, the "windmill" would have to be mounted on the roof of the car and it could be used to recharge a battey while the car is parked.  If it was in use while the car was moving, it would increase drag and waste energy.  The car would have to be parked in a very windy location or for a long time between uses to charge the battery enough for a reasonable trip.  The battery would have to be much larger than the type used to start a car because it must store far more energy for a trip.  If you have an idea for a patent, you must file an application within one year of making a public disclosure.

We used to build a Go-Kart frame similar to the store bought and make enough room for the Engine to mount behind the Seat. IF, it not have electric start take into consideration room to use the kick starter or mount a Rope Pull maybe using a compression release. Make a rod to run where you want the hand shift and use pedals for Clutch, Brake and Gas. Good Luck, it a fun project and you should be able to use a nice size tire, look for a cost effective Tire set up.

Use marble tracks and domino's.  You can also use hot wheels on tracks to keep it cheap.

Here's someone who claims to make one.  You might e-mail them and ask where you can buy one.\n\nhttp://www.chassis-plans.com/Press/press-release-31045.htm

Please use springs, or rubber bands.

Well it is pretty easy to build a simple motor. There are instructions at this website.

How to make a simple Van de Graaff Generator\n\nITEMS:\nPlastic Tupperware (microwave oven safe)\nSome wires\nNail\nSmall DC motor \nPiece of PVC pipe (approx. 3.8 cm in diameter)\nBroad rubber band \nWooden skewer\nPlastic bag\nRoll of tape\nSoft drink can\nMineral water bottle\n2 3volt batteries\nBattery holder (optional)\n\nPutting it together:\n1) Cut a hole in the middle of the bottom of the plastic container.\n2) Glue/tape the motor to the lid, making sure the shaft is at the centre of the lid.\n3) Using a hot nail (can be heated at the stove), make two holes near each other for the wires of the motor\n4) Thread the wires through the two holes (the two wires will connect to the batteries)\n5) Cover the container with the lid. (Inverted container in this case)\n6)Make another hole, perpendicular the motor shaft\n7) Thread another wire through(this will be your ground wire) \n8) Make the appropriate measurements for cutting your PVC pipe length and grooves(where the stick will rest)\n9) To make the roller, just stick tape to your stick and go round and round and round.\n10) Place the PCV tube on the lid, perpendicular to the motor. \n11) Thread the stick thru the rubber band and place it in the grooves.\n12) Make sure both rollers are parallel to each other when you thread the bottom of the band to the other "roller"\n13) Cut the top of the soft drink can.\n14) Cut both ends of the mineral water bottle off, making sure that it isn’t shorter than the PVC pipe.\n15) Make a hole near the top of the bottle.\n16) Strip some wire, twist it, and poke it through the hole.\n17) Electrically connect the copper wire to the soft drink can.\n18) Tape everything in place.\n\nWhen you put everything together, you get a crude Van de Graaff generator. Make sure the combs (end of wires) are near the belt and rollers. Make sure that when you run it, the belt doesn't slip off. If it does, make sure both rollers are parallel to each other. Also, try to superglue the motor to the Tupperware lid.\n\nWhen you first run it try taping strips of tissue paper to the can. It should start to rise seconds after the batteries are connected. If this fails, put your finger near one of the tissue strips. The strip should be attracted to your finger.\n\nPlaces with high humidity can be a real problem for electrostatic experiments. Try working in an air conditioned room to help overcome the problem.\n\nThe last two links are the best ones and both include detailed step by step process with pictures.

How about a caterpillar? Check the crafts dept. at Wal-mart. Use stryo balls for the body, just glue five or six together in a line,  which you'll need to paint of course, add pipe cleaners for legs, just use wire cutters to cut them in thirds and just stick them in and bend them down, then use the stick-on googley eyes that they sell, and add a colored piece of paper cut for the mouth, and two toothpicks painted black and stuck in his head for antenna. Easy, and uses 5 materials

if u know how to build a cricuit i can explain you .!!!!\n\nbut if u dont know how to make a circuit... u r in wrong way ... u probably need to learn circuit making... or better yu buy a remote from a shop ;-)

You need something iron (like a nail) wrap the wire around to make an electromagnet. You could wrap the wood lengthways with some wire and then wrap another wire shortways around the assembly and hook to the battery but an iron core is much better. \n http://www.energyquest.ca.gov/projects/electromagnet.html\nBTW You do have most of the parts to make a simple radio receiver also.

Make a solar car, a small one albeit.

there are 3 ways to do this. \n1) electronic method (digital method). it wont be possible for me to show you the circuit diagram here. however its efficiency is very high!\n2) transformer - you can make a transformer in which the primary coil should be of less number of turns and secondary coil should be bo many times higher in number. i calculated it and it came to the value of 20,000 turns in secondary coil. it wont be possible for you to make such a big transformer?? even if u make one, where will you keep it? and also it consumes a lot of electricity to give a low out put. that means that its efficiency is low.\n3) motorized convertor - you need two motors. one that runs on 12V dc and the other that runs on 220Vac. dc motor should be powerful enough to rotate the ac motor. so, you can use the motor of the car ventilation system. its very-very powerful!!! it seems that you are from india. so, you can go for the motor of maruti car. now all you need to do is to connect the shaft of both motors and run dc motor. along with it, ac motor will also rotate and it will act as a dynamo and produce current. though the current produced will not be sufficient to run any heavy electrical appliance. however you can surely light a bulb.\nhope that i have answered your question. for further enquiry you can mail me at\nmangeshome1982@yahoo.co.in\n\nall the best!!
