A team of 6 students and one teacher put this project together, and we have decided to put it on Instructables in hopes of winning a laser cutter, or at least a t-shirt.
What follows, is a compilation of our presentation and my own personal notes. I hope you enjoy this Instructable as much as we did.
I'd also like to thank Limor Fried, creator of the MintyBoost circuit. It played an key role in our project.

Step 1: Our original intention...
However, we had a problem. To quote my team mate Nick Ciarelli,
"At first we considered using a design similar to one of those shake-up flashlights and converting it so that a runner could strap it on for a run and have energy to charge their iPod or whatever device they use. The shake-up flashlight gets its energy from the interaction of the moving magnetic field of the magnet in the flashlight and the coil of wire wrapped around the tube the magnet slides through. The moving magnetic field causes electrons in the coil to move along the wire, creating an electric current. This current is then stored in a battery, which is then available to use for the flashlight bulb/LED. However, when we calculated how much energy we would be able to get from a run, we determined that it would take a 50-mile run to get enough energy to charge one AA battery. This was unreasonable so we changed our project to the bike system."
We then decided to use a bike-mounted system instead.
