A person pedaling a bicycle can accelerate to a speed and maintain it comfortably up to a point. Beyond this point of energy expenditure by the rider, the amount of energy (kinetic and heat) generated by that person rapidly drops off. This is because the amount of energy needed to keep RPM's(rotations per minute) of the crank shaft up have exceeded the amount of energy the rider can actually produce and expend. <ref name="Perry">http://users.frii.com/katana/biketext.html</ref> | |||

Background
A Bicycle Rodeo, or Bike Rodeo, is a bicycle safety event for children, generally ages 6-14. Events can include lectures, workshops, inspections, demonstrations, and generally a practice course. Several rodeos are held each year by Humboldt County, California health organizations.
Opportunity Definition
As an attraction for these events, workshop coordinator Brian Olson, of Rio Dell Community Resource Center for the St. Joseph Health System, has teamed up with Robert Camacho and Eric Recchia of Humboldt State University’s Engineering 305 class on Appropriate Technology to create a bicycle blender. A bicycle blender uses human pedal power to operate a blender. The blender will be used by kids attending the event to demonstrate the uses of pedal power and allow them to make their own smoothies.
