Comments on: How to Get More Voltage from the PicoTurbine Windmill http://www.super-science-fair-projects.com/super-science-fair-projects-blog/fqa/picoturbine/ The Super Science Fair Projects Blog is a place to get science fair project ideas, topics and experiments - to ask questions and get answers from other parents, teachers and students.

Turns out that you cannot improve on one part of the project without improving the whole thing, stator and rotor. Which is the basis of my son's project now. Thank you to the forum group for your input, and to the group responsible for providing this great learning project. Okay,

Now, granted the magnets were probably half the width of the original ones, but they were positioned every 45 degrees and reversed polarity. My next attempt will be to add 4 more wire coils so there are double the lines of flux to generate more power. I tried using 8 magnets as I described above, but I actually got less voltage output.
