It has been shown that a reasonable amount of power can be realised from a generator using recycled magnets from the dumpsites

7.4 Cost involved in the design

The overall cost of assembling this wind generator system will be very cost effective since all the materials are recycled from the village, and the entire system will be assembled by local artisans.

7.5 Validity of this thesis

Small power that can turn on small lamps will really be appreciated in this village as children will be able to study after sunset. This will clearly have a wide range of positive developmental benefits on this community.

Chapter 8. Recommendations

Based on the above conclusions, the following recommendations were drawn:

1. For a more accurate recyclable wind turbine design, all its components such as the drum, the tower, rotor disk and cables must be explored in depth. The following must be considered:

· Investigate how to extract maximum power from the wind using the drum, and how to prevent the drum from over spinning.

· How to use other irregular recyclable magnets in the village in the generator design.

2. Investigate how a permanent magnet generator topology can be changed or re-designed to accommodate the design of a generator with the shape of the loudspeaker magnets.

3. Look in to how the magnets can be removed from the speakers, since very strong clue is used to mount them, how this can be done in a cost effective way.

4. The axial flux permanent magnet topology should also be looked into to compare it to the radial flux type.

5. The exact costs of assembling and maintaining the recycled wind turbine should also be incorporated in the design procedure.

6. With the little output power generated in this thesis, this project must definitely be taken further to alleviate the electricity problems in South Africa.
