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.

Manufacturing Of Single Solid Oxide Fuel Cells, Jonathan Torres-Caceres

Electronic Theses and Dissertations

Solid oxide fuel cells (SOFCs) are devices that convert chemical energy into electrical energy and have the potential to become a reliable renewable energy source that can be used on a large scale. SOFCs have 3 main components; the electrolyte, the anode, and the cathode. Typically, SOFCs work by reducing oxygen at the cathode into O2- ions which are then transported via the electrolyte to the anode to combine with a fuel such as hydrogen to produce electricity. Research into better materials and manufacturing methods is necessary to reduce costs and improve efficiency to make the technology commercially viable. The …
