1.    The results of our wind machine were good we lifted the .523 kgs. With ease. If someone else were to remake our machine I would tell them to make all the blades more even and to space them evenly. Also the more surface area the blades have the faster they  go.

2.    If I had to do an investigation like this again I would make the variable the angle of the blades. I might also see if the size of the hub made a difference.

3.    All the wind machines that I have seen have small blades, so if they made the blades a little bigger then the machines might spin faster.  The angle of the blades also makes a difference.
