What Kind of Money does a Wind turbine technician make?

Quistion for anyone in the wind industry.?

I will be graduating from a wind turbine technician training program in may 2013. Do you believe there will be a lot of job openings than? What should I expect for an average starting wage? And what do you think about going into the cell tower industry instead? Thankyou!

Are there any reasons why a larger number of blades would be more efficient ona wind turbine rather than less?

For science, we did an experiment to determine whether 3, 5 or 7 blades were more efficient on a wind turbine. Our results showed that seven blades produced a higher voltage, and three the least.However, now we ahve to find theoretical background which would support this, and everything I find on theinternet says three is better than more. does anyone know any benefits of having more blades?

Thank you.

What motor should I use for a DIY Mini Wind Turbine?

I read that stepper motors from old tape drives or dot-matrix printers are low rpm and good for making wind turbines, but I can’t find either of those for the life of me. Are there any other common household items that would have a suitable motor to use as a wind power generator?
