The alternator design has not yet been bound any particular wind-turbine type. However, if the alternator is going to be directly driven by a wind-turbine, different types of turbines from horizontal axis (HAWT) to vertical (VAWT) and their respective variations will require various modifications to the rotor design. We've been trying to consider which design may be more appropriate using our existing construction methods. Considerations that we have taken into account is:

*the limitation of A3 sheet size, if long blades are required the turbine design should allow these to be incrementally extended to increase the turbine area.

*Laser cutting is suitable for flat material and thus designs that really depend on air-foil shape should be avoided.

A VAWT flat blade Darius type turbine is simple when it comes to mechanisms, as the wind-turbine does not need a tail construction or to rotate to point towards the wind, further they seem to be references saying that such designs are more silent. Additionally, the turbine area can be extended in a modular design that adds sets of 3 blades vertically on the pole where the turbine is mounted.

On the other hand they seem to heavily depend on air-foil blade shape in order to generate torque, or even begin to rotate for that matter.

The picture from a Darius flat-blade turbine designed by Chad Maglaque called the Jellyfish. Such a design could allow a modular expansion of the turbine.
