Need help! I need to make a super-efficient wind mill out of paper!?
My current plan is to make the classical 4-bladed pinwheel, but I am not allowed to use a pin!
First answer that works well gets 10 points!
1.) Is there a wind mill design that creates more energy than the design that I proposed? I have a limited amount of paper and manila folder paper.
2.) What could be a plausible replacement for my pin? Remember, I am aiming for this design: http://www.thetoymaker.com/Toypages/21pinwheel/pin...
P.S. This is the generator. The fan must not be able to hit the generator, lest it slow down. http://www.sciencenc.com/Tournament_information/Ev...
Just found out I can use tape in the experiment. How can this replace the pin, and/or add efficiency to my fan?
Also, how does size affect the efficiency? Should I make it large or small?

I only have one thing to say and that is that the most efficient type is clearly the type seen in power generating windmills..
These have long 50-100m tilted parts, just make sure you stick to that and not like, and old fashioned fat one

(1): It would be better to use a three sided fan blade. it uses less paper, and is easier to make. Height matters in a fan, and shape, and sturdiness is even more important. Add more support, and make it higher. (2): A paper clip, or a magnet. Attach string to the fan, and use a strong magnetic force that pulls away from the fan, The string will keep it in place. That way no physical force will slow it down. (3): A long stick, or magnetic force would prevent the collision of the generator, and fan or you could use a longer pin, or object to separate the fan from hitting anything.
Source(s): I'm the source. Make sure to use super glue with the magnets or else they will push each other out of the way, anything works. Just use something to keep it in place. Using a strong magnetic force to spin a fan is a very good idea. It's even used in modern fans for it's efficiency, and provides no friction. - eeLv 44 years ago
a wind mill,skill milling grain by skill of making use of the wind , they have been used heavily in Holland till now technolegy arrived ,and helped the persons by skill of offering low cost potential ,no longer plenty helped the surroundings . as we communicate we use wind potential to generate electricity they are wind potential stations ,yet they are not turbines (no longer something to do with grinding wheatgrains to any extent further) the advantages of wind potential turbines are that they help the surroundings considering's an selection skill of producing electricity , we don't could burn coal (and so do no longer could mine coal) and there is not any black smoke that pours an infection into the ambience, with the very tall chimneys , it is likewise much less hard artwork in intensity and altogether an particularly sparkling way of acquiring loose potential from the wind those wind potential turbines are heavily utilized in Denmark ,they seem to be somewhat a watch sore on the horizon ,however the environmental reward out weigh that extra extra wind propellars are additionally used to pump water to the floor in remoted places in farms in (it is likewise no longer electricity yet works with apersistent shaft and gears that perform a pump)Australia ,the Americas .Africa .and doubtless everywhere else

This might help you to create your windmill. As using anything but a pen I do not know unless you use a paper towel roll.
