Wind Turbine Tour

That was pretty cool. I've always wondered what is up in the housing.

I like the newer wind turbine generators which use neodymium magnets.  No gear box, the generator is directly driven by the propeller right on the axle.  The trade-off is much more expensive generator, but, no drive transmission mechanical parts to break down over the years.

Notice the shape of the generator housing.  A direct shaft.  Though, this design is new and it's only beginning to gain adoption.
