Atmospheric Water Harvester, Justin K. Lam, Jacob David, Jessica Mabry, Ben Brough

Mechanical Engineering

Atmospheric water harvesting uses the vapor-compression cycle to collect water from the moisture in the air. The system’s components include an evaporator, condenser, compressor, fan, and several expansion valves. Condensate from the air is then funneled into a receptacle, which determines the efficiency of the water harvesting system. For this senior project, the goal is to increase the efficiency of an existing atmospheric water harvester.

The Effect Of Biocomposite Material In A Composite Structure Under Compression Loading, Benjamin Andrew Sweeney

Master's Theses

While composite structures exhibit exceptional strength and weight saving possibilities for engineering applications, sometimes their overall cost and/or material performance can limit their usage when compared to conventional structural materials. Meanwhile ‘biocomposites’, composite structures consisting of natural fibers (i.e. bamboo fibers), display higher cost efficiency and unique structural benefits such as ‘sustainability’. This analysis will determine if the integration of these two different types of composites are beneficial to the overall structure. Specifically, the structure will consist of a one internal bamboo veneer biocomposite ply; and two external carbon fiber weave composite plies surrounding the bamboo biocomposite. To acquire results …

Database Design For The Collection And Visualization Of Sustainabilty Data, Henry A. Kozlowski, Nikhila Perugupalli

Industrial and Manufacturing Engineering

The goal of the project was to create a database that would be a repository for the high volume of sustainability data Illumina would like to collect. To couple with the database the project team’s goal was to design a system for visualizing the data graphically. Illumina required a database system that would be user-friendly, easy to add, delete, and edit data inputs, as well as a program that would allow the user to easily sort and graph data. The intent of the graphical representation of the data is to publish the graphs in a monthly report that would be …

Low-Cost Scheffler Solar Concentrator For The Developing World, Darren Sholes, Jason Morgan, Nicholas Fuller

Mechanical Engineering

This report will outline an approach to design, test, and build a low-cost Scheffler solar concentrator to be used for safer, sustainable and cost effective cooking in the developing world. The function of Scheffler concentrators and a proposed method to create one in an economic, environmentally conscious manner is summarized. If successful, the design will be presented in a way that is readily and freely available to anyone in the world. The authors have examined existing technology and researched the availability and cost of different materials. Analysis was performed in order to verify the feasibility of the different design ideas …

Swing Human Powered Generator: For The Dc House Project, Juan Vicente Avelar, Juan Jose Galindo, Juan Pramyr Ramos

Electrical Engineering

The Play Park Human Powered Generator project addresses various ways of generating power. More specifically, this project entails the design and construction of the Swing Power Generator to provide electrical power from mechanical energy. The swing generator will eventually be used as part of the human-powered generators utilized in the DC House project.

A swing generator prototype was built for this project, which demonstrates the feasibility of its use for electrical power source. Detailed design and construction of the swing generator is presented in this report along with results from hardware testing.
