Will N52 Magnets Offset Costs vs N50 in a Piggot Wind Turbine?

AI Thread Summary
The discussion centers on the cost-effectiveness of using N52 magnets versus N50 or N35 magnets in a Piggot wind turbine project. The original poster is exploring whether the increased performance of N52 magnets justifies their higher price, as N52 magnets cost around $10 each compared to $1 for N35s. They plan to use N45 magnets instead, focusing on maximizing voltage output at lower RPMs due to their location outside the wind belt. The conversation highlights the importance of understanding magnetic properties and suggests consulting datasheets for more detailed information. Overall, the project aims to balance cost and efficiency in building a homebrew wind turbine.

I'm back in school after decades away and taking alternative energy .. just because it was interesting.
In the wind power class we talked about Hugh Piggot and the home brew HAWTs he makes and teaches. That gave me the bug to see if I can do it. I'm pretty sure I can buy a used turbine on EBay for cheaper, but that's not the point.

My question for the brains here is:
Will a N52 set of magnets generate enough extra to offset the costs vs a N50 or less.
It seems like a 50 x 20x 3 N52 runs around 10 bucks a piece but the same size N35s are around a dollar. I was tempted to get 24 of each and see the difference but $240 seems like a more expensive hobby question then I want to play with.

Also he recommends the 50mm magnets and the coils are wound to match. If I go with a smaller magnet with the same coil will it work at all or wind the coils smaller will it not generate at all?

your question is about the magnetic properties of your proposed magnets
a link to their datasheets would be the first step toward an answer.

That said, the "how to " article you linked is best one I've seen.
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
