Does anybody know what is the size of the box for the 3 points bonus (7f.)? I couldn't find the specifications in the Wind Power rules.

Does anyone know if we need some type of calculator for Wind Power Div. B?

The reason you couldn't find a specification for the box is that there isn't one. The box isn't a size limit - it's a container. Any box that your device fits in is suitable.

The rules tell you that you may bring calculators. You should have read them, so you should know this
(If you haven't read the rules, please read them. About the saddest thing I've seen in science olympiad is when some kid has spent ages working on what they thought was required for the event, only to discover at a competition that their teacher had told them the wrong thing.)

For Wind Power, rule 2b says that teams may bring two stand-alone calculators of any type. This doesn't guarantee that you will need a calculator for every test, but it's likely that there will be some calculation questions on the test that would benefit from the use of a calculator. I would not expect, for a B level test, to require more than a basic calculator.

I am new to being a SO coach and trying to learn quickly. I am coaching wind power. The leaders at my school are also new and have no prior experience with wind power since it has not been done for a few years. I have searched all of the information that I can find but cannot find specifics of what we need at the school so that the students can test their own device prior to the events. Do we build our own power source? Do you buy on somewhere? Could someone supply me with a list of must have supplies?

For testing at school, you'll need a box fan as the power source, a stand with a mounted CD motor, and a multimeter to measure the generated current.

Question: Are teams allowed to use a CD that does not have the shiny aluminum film on it?

The rules never mandated that the CD being used must have the shiny film on it? Can participants remove the film on the CD or purchase a clear CD that does not have any film? The rules don't have anything explicitly prohibiting this and this does not change the structure of the central disk.

In the rules manual, under wind power, Section 3, Part C is the clause I'm concerned about.

Removing the film on a CD definitely violates 3.c. in that it is a modification of the CD other than attaching rotor blades.

As far as some commercially available CD without the film, I don't think that would be permitted either. While the rules don't explicitly define what a CD is, I think most supervisors would interpret "CD" to only include stuff capable of storing data that could in turn be read using a standard laser drive, rather than just anything with an identical shape to a CD.

All that being said, yes, it is possible that a supervisor could interpret the rules differently. But I would seriously question the risk-reward tradeoff here. In the event that it is allowed, you've reduced the mass of your device by maybe 10%. In the event that it isn't, you could get a zero for the speed scores.

Hello,

At a recent invitational, the event supervisor's test stand collapsed while my blade assembly device was being tested. As a result, my blade assembly device broke as the event supervisor's test stand broke. It was not my fault, and the event supervisor also claimed responsibility for the incident. Their setup broke while my device was being tested. In such an event, what compensation should be given to the student? How should the event supervisor ensure that the competition is fair for the student whose device broke even though it was not their fault? What is the course of action to be taken if it's the event supervisor's fault that a student's device broke?
