We have consistently been getting 1200 mv, but when we tested it today, it went down to 700 mv. We tested 5 different turbines, and all of them went down about 300 mv... We thought the multimeter battery was low, so we replaced the battery, but the results were still 200 mv lower... Any suggestions on what the problem could be?

Were you working with the same fan? Some seem to create a stronger wind than others.

yup, exact same one

but... we got back from regionals, and got 1ST!! I guess it was a problem with our motor

What were your voltages for high and low?

What were your voltages for high and low?

1500 high, and 800 low

1500 high, and 800 low

Piggybacking off of illusionists post (I'm his partner). Our score was the highest at regionals, but I'm sure that that kind of score would be average at states. Any other Michiganders getting comparable speeds? Or any other B team for that matter.

I'm from MI and in B. I got 1200 on high and 700 on low.

What is a top voltage at state in MI or any others

Our school has achieved a combined 2725 mv with a three blade design (1700 mv on high and 1025 mv on low).

Great job, but our school's has gotten almost double that! We had a professional wind-mill builder actually come in and lecture us - it was great!

To be honest, ours is the best. And if you want to argue:

That guy looks funny... I think he has weird glasses.
