Biodiesel: Methanol Recovery Project
Jacob Munson
This project aims to make biodiesel production more sustainable and economically viable by recovering unused methanol from waste glycerin. We constructed a reflux column still to boil off, then condense, methanol from waste glycerol. Purity of the recovered methanol is critical to its reuse in biodiesel production. The remaining glycerin was tested as a fire starter and soap product. Further research and experiments will create a methodology to recovering methanol and its recycling.

Disabilities Resources Electric Tricycle Brake System Redesign
Levi Mattas, Charity Oresic
Due to their lack of strength to apply brakes, riders of the electric trike rely solely on the automated braking system. The current braking system has an unreasonable stopping distance which creates a safety issue. Focusing on three braking variables — the force, the braking surface area, and mechanical application type — we researched and then tested a number of possible solutions. From this work, we determined an effective braking solution.

Brushless DC Motor Rear Wheel Hub Integration
Peter Shenk, Timothy Stocker, Joshua Zimmerman
More efficient ways of transportation are needed for the future. The goal of our project was to integrate a highly efficient electric motor into the rear hub of a motorcycle and test it to ensure all specifications were met. Mounting a motor in a motorcycle hub requires precision machining and balancing. Custom plates and adapters were carefully made to insure that the motor would work properly.
Webcast 2009: Uniform Tricycle Frame Redesign
The Engineering IPC Presentation Webcast is in progress!
Now Playing:
Uniform Tricycle Frame Redesign
Andrew Betteridge, Brant Copen, Jonathan Hollinger
The team redesigned the tricycle frames currently manufactured in Burkina Faso. They utilized finite element analysis to compare possible frame redesigns and chose one in which the rear wheels are cantilevered, greatly reducing the frame weight. This utilizes an innovative design for the wheel support requiring additional analysis and testing. The design features more user-friendly elements, including an adjustable reclined seat, easy battery access, and interchangeability for either hand or electric power.

Electric Motorcycle Power and Battery Management via Microprocessor-based Circuitry
Matthew Ayre, Amy Bowie, Brice Farrell, Paul Gustafson
Using a microprocessor and additional circuitry, our team designed a system to monitor a new Lithium-Ion battery pack and developed an original algorithm to control the drive motor for an electric motorcycle. The custom microprocessor-based system is the main step in an upgrade to an in-hub brushless DC motor and a higher voltage power source. This, along with a lightweight Kevlar battery cradle, will increase the efficiency and improve the handling of the motorcycle.
