Thesis Topic Ideas: Solar Cooker Design and Efficiency Testing
🎓 Academic Journey Progression Map
✓ Why This Topic Works (Student & Parent Reassurance)
Why this topic works for Grade 8-10: Fun physical project building a working device out of recycled materials, clearly showing heat absorption and energy transformation.
1. Introduction & Problem Statement
Overview: Design, construct, and measure thermal performance of a low-cost parabolic or box-type solar cooker built using recycled cardboard, aluminum foil, and glass.
Background Context (Nepal): Solar thermal cooking offers a clean alternative to Liquefied Petroleum Gas (LPG) and firewood in sunny regions of Nepal. Hands-on construction demonstrates solar energy conversion.
2. Research Objectives
- ›Construct a box or parabolic solar cooker using cardboard, aluminum foil, and black paint
- ›Measure water heating rate and peak temperature reached during peak sunlight (11:00 AM - 2:00 PM)
- ›Compare heating efficiency with and without a glass/plastic cover sheet
- ›Calculate simple thermal efficiency percentage
3. Proposed Methodology
- Assemble cooker frame using cardboard box lined with reflective aluminum foil
- Paint internal metal container matte black to maximize solar absorption
- Expose cooker with 500 ml water to direct sunlight, recording temperature every 15 minutes using a thermometer
- Plot time-temperature heating curves in Excel
- Evaluate insulation effectiveness under varying wind conditions
$ Worked Example / Sample Scenario
Sample Scenario: A Grade 10 student builds a cardboard box solar cooker in Pokhara. In 90 minutes of noon sunlight, 500 ml of water reaches 78°C, proving thermal absorption principles for the school science exhibition.
