K'NEX WIND TURBINE

A simple K'nex wind turbine and can be used to power your latest project.

Edit: Came back 5 years later and cleaned up my horrible grammar. Unfortunately I don't own K'nex anymore so I'm stuck with the bad photos.

Design and beautiful
Thank you for this design
good job making the rotors
gear belts are the most effecient method of getting from the turbine to the generator. an old electric typewritter had gearbelt drives and 110 volve mini motors not sure if there induction motors or the kind that can serve as generator when turned. magnetic motors are they called? anyway we used these on several prototype centrifuges so they work great on samall projects may be smaller motors on r c controled cars or some thing. erector sets had those pully wheels and a ruberband this things prototype it's about the ideas it generates isn't it. it's generating right now ideas!!!

I can't see the 'blue connector to rod' piece.

Motor PLEASE?
to add a generator all you need is a small DC motor from a toy or something. hook it up however (that part is easy) then if you spin it, it acts as a generator and produces a small amount of electricity.
i used this technique with a wind turbine of my own, however the outcome was a puny 0.3v with strong wind. but its a start.

I really appreciated this design. However, I need to know how to add a motor. Please provide me with instructions at holler141415@netzero.net.
Thanks!

How do you plan to connect it to a generator?

Check your spelling, there are some bad mistakes in there - yoused should be used, for instance.

I would attach a motor/generator by using a K'nex motor and K'nex gears. Or I would use the white 8-way connector and green connector pegs to make my own gears. Then if I didn't have a K'nex motor I would use epoxy or super-glue to attach a motor of my own to one of the white "gears". Another method is to attach the motor directly to the shaft. You could do this by using epoxy to attach it to one end. Or if you are so compelled, you could drill a hole in the end of the K'nex shaft and super-glue the motor shaft into the hole. Voila!! You would then have a generating station made of children's toys and various electronic equipment. Of course somebody would have to figure out all of the circuitry that comes after the generator in order to make it charge batteries or run laptops, for example.

i have a knex moter but how do i put it on and how will it make electricity??? cause wont the knex moter just make it go so plz tel how

can u show me how to put in a moter i built 1 different than yours after i put a moter in it ill put it on youtube so u can see it

ok i want to make this thing produce power... how do i do this.... how does a wind mill make power basicly.
hook up a geared dc motor so that one turn of the windmill equals a high amount of the motor shaft this will give you electricity through the motors terminals. I tested this by putting a motor in a vice and putting the shaft in the chuck of a drill. spin it up and sure enough you should get power. its just a matter of getting the right gear ratios and torque
thanx

I tried to make one..didn't turn out so well..I tried to make a tide turbine..same princible as a windmill, but it faces one direction and the "wings" are more in length that widith. -_ -_ -_ -_ -_ -_ -_ -_ sorta like that..pleh, hard to show with text.
I'd like to see this in action. Pretty sweet.

thats a great idea
arrow shot6 years ago
its cool, but its use for energy is low. id use it to power, mm...maybe a knex contraction that i dont feel like using batteries for.
THIS is what i think you need
LOL
I would like some pictures, but it's a nice idea.

Put the motor on because it is cool now but it would be way cooler when it generates electricity. I voting on it
