Q: Wouldn't it be better to use rare earth magnets in your PicoTurbine windmill projects?

That depends on what you mean by "better". Sure, rare earths would produce much more power. Neodymium magnets are currently the best there are, and they produce 3 to 4 times as much inductive force as the Ceramic-5 magnets we use. However, they cost 30 to 40 times as much per unit weight! If you do the math, you will find they would produce about 15 times as much power but would cost 30 times as much as Ceramic-5. Ceramic-5 magnets are also highly corrosion resistant compared to Neodymium. Neodymium magnets must be painted or plated to avoid corrosion.Let us point out that many commercial wind turbines use Neodymium or other rare earth magnets. This is because for those systems the cost of the magnets is not the over-riding cost of the whole system, and they can achieve better tower top weight and lower start up inertia by using the lighter, more powerful magnets. Engineering is all about choices and trade-offs! For a commercial wind turbine system, the magnets might be less than 5% to 10% of the whole system cost, so it could pay to use more expensive magnets and save money in other places. For something like our PicoTurbine-250 project, however, the magnets are something like 30% of the cost of the system, so we could not afford to double that cost, as that would jack up the price of the system by a large amount.In addition, super strong magnets are not safe in a classroom environment. Kids play around with stuff. If you drop 2 neodymium magnets at the same time, they will attract each other with such force that they can shatter and bits can fly off at a hundred miles per hour or more, which is plenty fast enough to blind a person. It is recommended never to handle neo magnets without wearing eye protection for this reason. That alone is a very good reason not to use neo magnets in a kit like Picoturbine which is used by school kids.So, if by "better" you mean "would produce more power" you are correct. If by "better" you mean "produce the most power per unit cost" then you would be wrong. And if you mean "better" in the sense of being good as a classroom project, the safety issue would again make you very wrong.Currently, Ceramic magnets give you the most "bang for the buck" and are far safer. If we were to use Neodymium magnets in our little PicoTurbine educational kit, the cost of the kit would increase by about $10-20 for the same amount of electric power generating capability. In addition, we'd have to include safety glasses for an even higher cost.However! If you can find a good, cheap supply of surplus Neodymium magnets that might shift the equation back in their favor, as long as you take the proper precautions with eye safety glasses. The primary supply of used and surplus rare earth magnets are computer hard drives. One supplier I have found is WonderMagnet. I am currently experimenting with a bunch of Neodymium magnets from them for testing, and I will as always post whatever results I come up with.
