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.

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.

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