no known diamter**

Completely understnadable, I've always been an unconventional type of person, and I appreciate your assistance. Yes, the air flow is over an unlimited cross sectional area; which I'm planning to reduce down to an unknown area. So with the area reduction it will be flowing through somewhat of a...

I have the wind power. I have a big window for rotation speed so that's not at the top of the priority list. Believe me, I fully understand this is an "Engineering" matter, especially since I am an engineer. I'm just not a EE or very familiar with building alternators. I'm a MECHE that works in...

Also, I know there is going to be power loss to friction, heat, etc... And I'm not exactly using a blade, I'm going to direct the air flow so it's more of a paddle wheel type shape. (Imagine something similar to a water wheel.) I know it sounds weird, don't worry... Hahaha!

I agree and that was my plan as an approach I just wasn't quite sure what calculations to do to get there. The wind speed is set at 25 MPH and cannot change, as for everything else I'm really just trying to determine everything before I build this rather than trial and error. I've found one...

Sorry for not being clearer.

No, I mean MPH. As I was saying this is not a typical wind application, and an RPM cannot be calculated yet because I have not designed the diameter of the alternator yet. So, it will have an air velocity of 25 MPH spinning it at a currently unknown RPM.

Yes it should be interesting and I'm looking forward to building it. As for your questions, not much is set in stone, the only requirements I need to have are voltage and amperage output but here are the answers: - I was initially thinking permanent but as I was saying if this needs to change...

One-off hobby thing, for now.

Literally building it.

I understand that this question has been asked before, but I've seen so many different formulas that I'm questioning which one is applicable to my situation. What are the correct formulas I need to build an alternator to meet certain requirements? I need to meet a specific voltage and amperage...
