Building a plastic 3-phase alternator for wind-turbine

We have began to explore the idea of building a low-cost alternator out of industrial plastic. This alternator should be tuned towards a wind-turbine application. The main aim is to design a turbine that can be manufactured out of cutting plastic-sheets, easily assembled and low-cost (<250 euros) so anyone can laser-cnc cut his own.

The picture below, shows the 3d rendering of our design of a single rotor and dual-stator (3-phase 9-coils each), made out of perspex. Diameter of the design is such so the parts can be cut-out of A3 plastic sheets. This particular size makes the design suitable for constructing with the abanduntly available CNC or laser cutters of A3 size. Our design aim is to achieve simplicity in construction & assembly, beauty and an acceptable efficiency (output/cost) ratio. Further, due to the nature of this open-design project we aspire that this project will generate community driven revisions to improve the initial design.

At this stage, we have finished designing a prototype and we are about to build it. I will create a project page once I have assembled the core of the prototype. Feedback or suggestions are welcome :)
