Quikchill : Thermoelectric Water Cooler, Franz Louie Chua, Brandon Ohara, Rachel Reid, Bernadette Tong
Mechanical Engineering Senior Theses
Motivated by the increasing residential energy utilization projections and the fact that water and ice dispensers consume 20% of total refrigerator energy, a thermoelectric water chiller was designed to provide a more energy efficient alternative. Implementing the chiller under the sink provides a convenient means to source cold, filtered water, thereby eliminating the need for water and nice dispensers as well as filtering pitchers. The cooling chamber design integrates thermoelectric modules (TEMs), which operate on the Peltier effect to cool filtered water down to 14 [degrees] C. The implementation of TEMs reduced current dispenser energy consumption by 82.4%, from 91 …

The goal of this project is to develop a 3U CubeSat nanosatellite bus capable of short duration technology verification experiments while providing compelling handson student education opportunities. This 3U CubeSat platform has been prototyped by the design team in order to demonstrate its capabilities. This spacecraft, the Unspecified Payload Active Attitude Control Nanosatellite (UPAACN), is designed to perform a 3-6 month technology verification experiment for a NASA test component and an SCU single-axis attitude control system (AACS) in Low Earth Orbit (LEO). This project builds upon the flight heritage of SCU's Robotic Systems Laboratory (RSL) and improves its satellite development …

Thermoelectric Cookstove, Christine Horman, Matthew Lee, Mark Wagner
Mechanical Engineering Senior Theses
A fuel efficient cookstove tailored to the needs of Nicaraguan small business owners that incorporated insulation and thermoelectric power generation was built and validated. There is a 4 inch layer of pumice rock insulation around the combustion chamber, which significantly reduces convective heat losses to the environment. The stove's ventilation system is powered by the electricity generated by thermoelectric generators. Preheated air is forced into the combustion chamber, which increases the combustion efficiency, reducing the fuel consumption and the harmful smoke produced. Through various testing methods, we found that the controlled airflow to the charcoal fuel allows the stove to …

Mechanical Engineering Senior Theses
We have constructed a quadrotor unmanned aerial vehicle (UAV) that could be used to supplement emergency response personnel, including police and military, when in the field. The SQUAD focused primarily on designing and constructing a sound structure for the UAV, as well as beginning controls work, which will be continued by another team at a later date. This quadrotor UAV has a video camera to provide a live video from its point of view to the user. It carries a global positioning system (GPS) to provide information on its location, and to navigate to waypoints in the immediate area. The …

A recumbent trike was designed and built for the ASME Human Powered Vehicle Challenge held at San Jose State University in April of 2013. The vehicle was designed to be low cost for use by commuters and as primary transportation in developing countries. The vehicle placed 11th overall in the competition out of 29 teams, and scored 8th in the innovation event, which was its best ranking out of the 5 individual events.

Mechanical Engineering Senior Theses
The purpose of this report is to detail the development process for a phase change material window shading system, which stores solar thermal energy and later releases it indoors to provide nighttime space heating. To do this, wax-filled louvers with thermally absorptive front faces were developed and outfitted with a control system, which utilized historical weather data to orient the louvers to specific solar azimuthal angles, thus maximizing the thermal absorption. The system was tested against other common window treatments in a pair of thermally comparable testing structures, and was found to provide energy savings as high as 50%.

Mechanical Engineering Senior Theses
The goal of Project ICARUS is to create an aerial videography system that is easy to set up, inexpensive, portable, and highly adaptable to any situation. This is accomplished by using a balloon mounted camera rig that is grounded by a number of winches. This system is able to obtain a higher altitude than similar systems and is much more cost effective because the system can be applied to a number of circumstances such as sporting events, disaster relief, wildlife videography, and aerial monitoring, to name a few. The ICARUS system allows the user to control the position of an …
