Abstract

Team Pure is dedicated to designing and prototyping a pedal-powered device that converts human-power into electrical-power for use in third world countries. Our target market is governments or relief organizations that would distribute the product in appropriate areas. 

The design contains two bikes (on stands) used to turn the shafts of a differential via chains and sprockets. The differential's output shaft then powers a generator.  The bicycles are removable to provide transportation for users when not producing electricity.  Key technical challenges arise in designing and fabricating stands and couplers for each component and interface, and maintaining necessary rigid geometries.   Despite these design challenges, the prototype is a feasible design and will be constructed.  Because of that, the only feasibility question is whether enough torque will be provided by the human input to drive the differential shafts.
