Wind Turbine Design: High Output for Low Wind Speeds

[Ac12992]

please excuse the writing in some of these messages as I am typing this from my phone, but I am looking to build a high output wind turbine. I have a few questions. I am a high-school senior and have a large understanding in physics.
my idea involves a 12 wing rotor as wind speeds are low in my area. so to make this have a high output I am looking at strong magnets and a 500 foot coil.
the design has the cylindrical magnets with 1/4 pre bored holes the magnets have a n48 strength 1.42 Tesla I think, these magnets are 1 inch long and I'm looking at using like 10 of them stacked in nnssnnssnn fashion to increase their strength. a PVC sleeve will be slipped over the magnets with a 500foot copper coil wrapped around that PVC. the shaft will be held by 2 pillow block bearings. how does the design of it sound so far? I've never really seen one like this.

To have a high output you need a high input, either strong winds or big diameter blades or both, worry about the generator magnets when you've sorted those two out.

I agree. The mechanical engineering part is the clincher. People who want to build a wind turbine system often buy / acquire the alternator as it would require some serious manufacturing skills if needed to be anything like optimal. The tower and blades are non-trivial, too. I wouldn't rest easy in my bed with something I'd thrown together, rotating at full speed outside my bedroom window.

Hello,

I am glad to hear that you are interested in building a high output wind turbine. It is great that you have a strong understanding of physics, as that will be very helpful in the design process.

Your idea of using a 12 wing rotor is a good one, as it will help capture more wind energy in low wind speeds. However, I do have some concerns about the use of strong magnets and a 500-foot coil. While these components may increase the output of the turbine, they may also make the design more complex and expensive.

I would suggest doing some research on the most efficient and cost-effective materials for wind turbines. For example, some companies use carbon fiber blades and permanent magnet generators to increase efficiency and reduce costs.

Additionally, I would recommend consulting with experts in the field of wind turbine design to get their input on your design. They may have valuable insights and suggestions for improving your design.

Overall, your design sounds innovative, but I would suggest considering the practicality and cost-effectiveness of your components before proceeding. Best of luck with your project!
