Parabola Solar Ovens

CSEF · 2008 Environmental Engineering

Zeke M. Lemann · Fieldbrook Elementary School, Arcata, Humboldt County

Overview

Objectives/Goals My project was to determine what kind of mirrored parabola produces the most heat. Methods/Materials Three solar ovens were constructed each using a different parabola. One parabola was deep, one parabola was shallow, and one was in between deep and shallow. They all had the same amount of mylar surface area. Results The solar oven that was in between deep and shallow produced higher temperatures more quickly. Conclusions/Discussion My conclusion is that the middle oven did better because it had a focus that was more sheltered than that of the shallow oven and it had more solar collecting area than the deep oven.

Summary statement

My project is about comparing different parabolic solar reflectors for heating efficiency.

Help received

My mother typed parts of my log. My father helped me build the ovens. My classmates helped me take temperature readings. Got advice from Humboldt State University professor about validity.
