When riding I often ride my bike on an indoor trainer (Fig. 1) , I and use a box fan plugged into an electrical outlet to keep cool. However, I'd rather not I would prefer not to use electricity to run the to fan when while the power I 'm producing produce on the bike is going goes to waste. Thus, the purpose of this project is to use the rotation of the bike trainer to drive a fan. Specifically, I want to transfer the rotation behind the real wheel of the bike to where the rider is seated at a rotational velocity approximately equal to a typical box fan, or about 500 - 800 1200 rpm.
Figure 1: The rear wheel of the bike causes a cylinder to spin via frictional force. This rotation spins the small wheel outlined in blue, which is a fan designed to cool the trainer mechanism. This wheel is where the rotational motion of the bike trainer is most accessible to be attached to the fan mechanism.
