Horizontal Axis Wind Turbine (HAWT) bearing from waterpipe

It's easy to make a set of blades, but hard to find a central bearing that is cheap, waterproof and can have an alternator integrated.

So I came up with this unit inside 90mm waterpipe.

The hub and ends are polyethylene cutting boards. Bearings and 25mm neodymium magnets can be pressed into holes cut with spade bits.

I haven't added any internal copper coils yet. Soon.
