My main project idea is to design an new Stirling Engine configuration, similar to a normal beta-type Stirling Engine.
A Stirling Engine is an engine that essentially converts a temperature difference into mechanical energy. Such an engine requires a heat source, a heat sink, and a sealed amount of air. The heat source causes that air to expand, and the cooling source helps it contract. The alternation between these two phases moves a piston. This is a very simplified explanation of the topic.
I found an article describing researchers working on a project very similar to mine, and therefore was forced to change my project. I am now working on a project investigating the incidence of radiation hormesis in bacteria. For more information on this topic, see my introduction and literature review.
The final version of my research paper (excluding title page and table of contents) can be found here. In addition, I created a brief technical manual. explaining the basics of culturing bacteria.
After science fair, students are paired into groups of approximately four students to engineer an assistive technology for a disabled individual. My group's product website can be found here.
