Instructables
Picture of Savonius make one from old CDs DVDs
I felt the need to make this instructable after searching in INSTRUCTABLES and other pages of the WWW and not having satisfied my need of knowledge I decided to make one and on the way of making it, why not take pictures and make an INSTRUCTABLE as well.

Sentí la necesidad de hacer este instructivo despues de buscar en las páginas de INSTRUCTABLES y otras páginas de la WWW y no habiendo encotrado nada que satisfaciera mi necesidad de conocimiento, decidí hacer uno por mi cuenta y porque no tomar unas fotos y hacer un INSTRUCTIVO tambien.

I like it!

I am thinking of mounting this to a computer fans motor to generate Electric for a USB device.

Hi Slim, I am having trouble with my browser to the point that when I try to reply your last message it sends me to reply to your first message. Please write to me directly to mi mail

mundodigitalnic@gmail.com

I will anwser.

But trying to answer what I understood from your mail is that the computer fan got hot when you blew it with a dryer.

I have some questions

did you blow the computer fan directly with the dryer?
Was the dryer HOT?
Did you modified the computer fan so that it could generate energy?

Write to me and we talk about
thank you

Carlos Arguello
Thanks for the reply!
NO , my dryer has a cold setting, just seems the body/hub was hot.
may be normal, for all I know.
I did no modification, just reading the out leads. of a straight out the box CPU fan. hte pix I sent was of a diff attempt, wiht a fan that was out of order, tried to start from scratch.

To get the CPU fans to generate energy you must modify them, here I have a link in Portuguese but there are a lot of indications on how to do it in English

ope you enjoy this. By the way you can use one of these Fans to generate energy with the SAVONIUS as the propeller and torque

Hi Slim49,

Thank for liking my Project and hope you áre able to mount on it a fan motor to generate energy.

If you use a Computer Fan and modify it you can generate between 7 and 12 volts, it will depend on the wind speed you get.

If you do your savoniuos a Little larger tan I did you should get more torque on it.

Let me know when you finish your Project

Thank you

Carlos Arguello
Hello,
thank you for your interest.
I tried to use a CPU fan with a hair Dryer test blower. only got a volt & 1/2 dc out of that! :-( and the fans body got really hot
see pic, I then took an old fan apart & dremel ground off all the circuit traces to expose the 4 post on each comunators. tried various connections to get some output, Got ZERO_ ZIP, nada.

any ideas?

Should try to make one, it really works and is fun, I am plannung to use mine to power a small axial flux generator
COOL IDEA! I'DE USE 26 GAGE WIRE FOR 4 COILS AND FOUR, 1/2 INCH BY 1/8 INCH MAGNETS FOR EACH MAGNET ROTOR. I BET IT WILL SPIN NICELY.
