1. In the link I provided it shows the how to wire the coils together. You
   link the coils on the stator so it ends up being one continuous wire. Wire
   it such that if you follow the wire with your finger, as your finger
   circles around the coils it will end up alternating between counter
   clockwise and clockwise. 

2. Please let me know about the orientation of the coils. I will like to know
   how to connect all of them together to get the output current. I know you
   said you wound them in cc and acw. Say if you have one wound cc then the
   other will be acw. Thanks this was the best video of all. Your explanation
   if perfect.

3. can you further explain the barring “system” you made 

4. Hi, I am curious what wattage your system put out?

5. The original designer wanted to demonstrate electricity production without
   using the power grid. It seems ur motor runs with the power grid plugged in.

6. Hi Dexter, The answer to using trapezoidally coils is too long to answer in
   the comments. Try doing a Google search for “Design of a Lab Setup for
   testing Stator Windings in Ironless Axial Flux Machines”. The difference is
   negligible for a science project, it only matters when you really want to
   squeeze out every last bit of inefficiency.

7. where did you get the spec info about the shape of the magnets and shape of
   the coils? In the video you said the magnets should be square or
   rectangular and the coils should be trapezoid

8. The system produced a maximum of about 18 watts with the simple straight
   brass nozzle.

9. What generator did you use? Did you run a wooden dowel through the center
   so it spins freely within the PVC tubes?
