The maximum power achievable by any turbine of 25 cm diameter at 6 m/s wind velocity is 3.91952882475 W. Therefore even just 1 W loss by the bearings is a significant loss for this turbine. And usually RPM is related to moment of inertia of the rotating body. The total mass (including shaft...

If you wish, then I can share the STL file with you. Make a 3D printed prototype and test it in your own way.

It's a 25 cm diameter turbine rotating with 360 RPM at 6 m/s wind velocity. That means the velocity at the periphery of this turbine is 4.71 m/s. Do you think it's a bad performance?

As I have told you before that first I have tested it by putting it on a ball point pen under a ceiling fan. And in the second time, I have tested it under the same ceiling fan after the ball bearings being attached. If I can show you the videos, the differences will become crystal clear.

With some modifications.

In that case, kindly believe my words for now.

For some unknown reason, I haven't been able to post any video. Can I send those to your inbox?

I recently have made a wind turbine based on Michael Waters basic design. It has 25 cm diameter and two bearings are attached to the shaft. At first, I have tested by putting it at the top of a ball point pen under a ceiling fan. You can see how it rotated in this video. But when I added the...

I don't want to copy this design and what I want to make doesn't need any kind of welding. My point of interest is the flexibility of the sheet so that I can be bend and shaped in a desired way.

My only intention is to know what kind of material has been used to make the blades. I can't answer those questions. Only way is to make one and find out what has been said is true or not. But in the video, you can see that the electricity generated is enough to ran a fan, which I can guess is...

A few have already asked, but the youtuber hasn't replied at all. Thanks!

After seeing this video, I have decided to make a homemade version of this machine. The axle and other parts can be taken care easily, but I want to know what kind of material is being used to make the blades of this turbine. These part is the most important part while making the turbine.

A simple market available tachometer will be enough. I have guessed it because I have tested the flow velocity from a ceiling fan with an anemometer not so long ago.

The flow velocity from a common ceiling fan is around 2.5 m/s. You can check from the first video that even at this velocity, the turbine is rotating well without the shaft and bearings. At least this shows that the power output will be sufficient at higher velocity. Though I haven't measured...
