It's a two part event. The first part is a lab about energy. You'll see the different stuff you need to know once the rules come out in a few weeks. The second part is called Alternative Energy. What you do is build a solar collector that will raise the temperature of water. Some examples of what to make it out of are: cardboard, aluminum foil, reflective fabric or material, glue, tape, mirrors, and tiles. When done, it must fit inside a 70cm cube. A 200 watt bulb will be used. According to the rules it seems like the distance from the bulb to the water will be different at every competition. The formula is: Increase in temperature + highest rate of increase in a five minute period = final score. Each part of the event is worth 50% of your final score.

This years (2009) task is to build a blade assembly that captures wind energy and generates voltage. The blades get attached to a CD. The score is based on power generated by high and low speed fans. They also have a testing part.

What's worked for me:

* The sides of styrofoam bowls. Angle them so that air leaves the CD at an angle.
* Plastic plates. Cut off the sides and use the bottom as a means to extend the CD to maximum dimensions.
* Packing tape. Take a piece of packing tape and lay it sticky side up on the table. Take another piece of tape and lay it sticky side down on the first piece. Cut and paste as needed.

Remember though: If you extend the CD to max dimensions, you add weight. Good luck!

Me and my partner are so confused and visited every site and still can't figure it out. What do you do. Do you put the blades on a C.D. and take the C.D., or do you Make the blades and then attach them to a C.D. there? We are so confused and really need some help. We have our materials and all but we are getting mad!!!!! :evil: :evil: :evil: :evil: :evil: :evil: :evil: :evil: :evil:

Step 1: Get a CD
Step 2: Attach stuff to it (I use lightweight tape for attaching. Glue seems to not work so well on CDs. Also, duct tape isn't lightweight.)

You have to provide your own CD. It should be part of your impounded final product. You do not need to provide the mount for the CD or the fan. However, you should have them for testing. The best/only way to find out what works is with trial and error.

Here's how to make the CD mount: http://soinc.org/sites/default/files/uploaded_files/PhysicalScienceLabSetup.pdf

Yeah, you glue/tape/attach the blades tha you have made PERMANANTLY to the CD, which you can cut and alter however you want as long as it is 30 cm in diameter and fits on the mount. At the competition, you will impund your CD WITH the blades attached, and then just test it at the actual event.

One more thing though. Did anyone have to shape their wings to catch a good current or did you just make a flat wing. If so how did you shape it?

What would be a good voltage to get? We believe ours is good but just to be sure we were wondering what an average and good voltage would be?
