I really think that these high values are being caused by the mount

The particular motor used as a generator can greatly affect the voltage produced. The input impedance of today's digital meters can range from around 10 to 300 megaohms, depending on the particular model used. Meters with different input impedance may also cause the measured voltage to differ under some conditions.

The bottom line is that you can only reliably compare measurements made with the same generator (motor) and meter combination.

if you are not using a CD motor it will affect the voltage...and just curious what are you using instead?

I have no idea what it is, it's some sort of setup for demonstrating wind power... we just had it lying around.

we got lucky, our tech coach builds a lot of the stuff they use for our regional building events we got to resue pretty much an exact copy of the blade setup for tests

[physicalsciencelab]

are they going to have wind power devices next year or will they have like geothermal and solar or what if you have an answer lease post it thanx

[fleet130]

are they going to have wind power devices next year

Since this is the first year for Wind Power, it should return next year, but there is no guarantee. If past practices are any indication, the list of events for next year should be released soon after the National Tournament. Keep checking the National Website for the latest news.

its too bad you cant make a polll without starting a new thread

but i was wondering, how many blades have other people been using

we used 3 blades


btw our team got like 5th at states so yea.......

[icyfire]

how powerful are the box fans at states

[Mr. Cool]

Our State had like a really high-powered fan.

[SSANationalTeam1]

Our State had like a really high-powered fan.

what did your fan look like?

[fmtiger124]

we used 4 blades
