www.epicphysics.com How to build a mini homemade small wind turbine generator using household materials. This simple micro wind turbine was made from scratch and was 100% made by me with materials that can be found in almost any home. I used a PC cooling fan, some 5mm plywood , some cable ties/tie wraps, scrap aluminum and some LEDs. This is no a vertical axis wind turbine, it is a miniature horizontal axis wind turbine.

Yep, this is the issue but if you actually made a propeller for a turbine you could actually turn it backwards then attach it to a good motor and the darn thing would blow a tremendous amount of wind.
With a PC fan the actual best way to do it is remove the blades and attach your own. So much more power this way.
Oh i get you now, i had no idea what was going on. Yeah it probably would work better that way, its a lot of hassle to get it of its axle though, plus the shaft the axle goes through usually doesn’t protrude all the way through if you get me so you’d have to make your own hole.
I think what they are talking about is like an airplane propeller can be used for a turbine but MUST be turned backwards due to one cuts the wind and in reverse actually grabs the wind which is what a turbine needs.
I don’t know if the propellers in the PC fan work like this but I bet so.
Guys, making your own home energy doesn’t need to be difficult (I used to feel it did). I’ll give you some advice right now. Search a alternative home energy called Xobotano Home Energy (search on google). Seriously, Xobotano Home Energy has save a large amount of my money. I probably should not even be talking about it cause I do not want a bunch of other folks out there running the same “game” but whatever, I’m in a good mood today so I will share the wealth haha.
No i didn’t change anything, all i did was take it straight out of a PC and take a few parts away so its was more aerodynamic
did you actually changed anything to the cooling fan? or you just opened it for curiosity?
Cool ill give it a try, thanks for the tip.
no not realy but you can or may get more energy out of it by putting the blade backwards
To make the electric motor run in reverse? Whats the difference though, its a DC motor so it shouldn’t matter which way its spun? Or does it?
no offence dude but for more energy put the computer blade backwardrs
everyone needs to google ” eBay Guides Not what you expect Carbon fiber wind turbine blades”
the truth about hydrogen appliances junky wind turbine blades.
Cool, i’ll go and check out some of your videos. This turbine is really easy to make ^^^
Thanks
plus I am making stuff
! it’s alwayscool to see the things you made with your own hands moving and working
