Thesis Topic Ideas: Solar Cooker Design and Efficiency Testing

✓ 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

1. Assemble cooker frame using cardboard box lined with reflective aluminum foil
2. Paint internal metal container matte black to maximize solar absorption
3. Expose cooker with 500 ml water to direct sunlight, recording temperature every 15 minutes using a thermometer
4. Plot time-temperature heating curves in Excel
5. 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.
