Using a car alternator for a DIY wind turbine anyone tried this?

[ecospinsolutions163]

I've been playing around with renewable energy and lately got really interested in the idea of building a small wind turbine. I came across an old car alternator lying around and thought it could work as the generator for the turbine. Now, I'm no expert on wind power, so I'd love to hear if anyone has tried this or has any tips on whether it's a good idea

My aim is to produce enough power to boost my off-grid solar system, particularly during those cloudy days. I'd really appreciate any insights on blade size, RPM requirements, or if I should look into different types of motors

Car alternators are a terrible choice for wind turbines, they need way too many RPMs to generate decent power, and people waste time trying to modify them. You're better off using a proper permanent magnet alternator from the start, it saves frustration long-term

I've heard about permanent magnet alternators, but are there specific types or brands that work best for DIY wind setups? And do they need any special controllers or wiring compared to a car alternator?

I completely agree with @Spartan_1 here that getting okay output takes way more wind than you think when you use car alternators. I'm also vouching for permanent magnet alternators if you're serious since they spin up easier and actually give you usable power. Far as I know @NotoriousNapper59 no special anything needed.

Guys, the whole point of a DIY project is for people to do it themselves and try new things. Yeah, the alternator wouldn't be my first choice either, but with some pulleys, anyone can make it work which is enough to at least test it how it works
