Wood There are many variations to the windmill design used by William Kamkwamba and refined throughout this&nbsp;section. However, there are some variations that are commonly used and have a negative impact on performance. One of these examples is using wood as the material to create blades - if . If avoidable , wood is a poor choice is it is a more heavy substance and requires more energy to begin rotation and achieve more frequent rotations.
uneven blade shapes&nbsp;
<br>  placing Also, It is very important that blades too low, must are evenly shaped as this can cause a wobble to occur. The wobble will result in reduced performance and will shorten the windmill's life based on additional vibrations. The windmill blades should also be placed high above all other obstructions in order to obtain a more powerful and consistent wind stream. A good rule of thumb is to place the turbine twice as high as the tops of any nearby houses or placed far enough away to not be affected by the boundary layer  <br>  <br>  <br>  obstructions.<br>
