Photovoltaic Cooking In The Developing World, Tyler Watkins, Christopher O'Day, Omar Arriaga
Photovoltaic Cooking In The Developing World, Tyler Watkins, Christopher O'Day, Omar Arriaga
Mechanical Engineering
The challenge of clean cooking is faced by hundreds of millions of people worldwide. We present a cooking technology consisting of a solar panel directly connected to an electric heater in a well-insulated chamber. Assuming continued decrease in solar panel prices, we anticipate that in a few decades Solar Electric Cooking technologies will be the most common cooking technology for the poor. Appropriate use of insulation reduces the power demand making low-power Insulated Solar Electric Cooking systems already cost competitive.
Solar Generation's Impact On Fault Current, Kody Heppner
Solar Generation's Impact On Fault Current, Kody Heppner
Electrical Engineering
California is paving the road for other states with the capacity of solar installations for residential and commercial entities. The added capacity of solar generation to the state's electric grid has an impact on power flow and fault currents. This project looks at the impact of solar installations on fault currents. Feeders with added residential rooftop solar and larger commercial solar installations may impact the system differently than a large, utility-sized solar installation. This project looks at the impact of both cases on the magnitude of fault current during many different fault types and locations that can occur within a …
Solar-Powered Hot Tub, Jonathan Peterson, Anthony Zepeda
Solar-Powered Hot Tub, Jonathan Peterson, Anthony Zepeda
Electrical Engineering
This paper discusses the design and implementation of a solar-powered hot tub. The concept of this project was to design an independently-operated hot tub powered by a 12V rechargeable battery, charged during the day by a single 400W solar panel. For this purpose, a twenty-year-old name-brand hot tub was purchased, in used condition. The plumbing, AC electrical wiring, and mechanical pumps were all removed and replaced with new components to meet our design specifications. Additionally, a solar water-heater was designed and integrated into the system to directly apply the sun’s heat to water pumped in and out of the tub, …
