🧠 Project Overview

This project was part of the Engineers Without Borders (EWB) Challenge 2023, which aimed to develop sustainable solutions for the Dawul Wuru Aboriginal Corporation. Our group designed a solar-powered trailer that delivers clean, reliable, and transportable energy to remote Yirrganydji community sites in Far North Queensland. The project emphasized cultural sensitivity, sustainability, and real-world engineering application.

🔧 How It Works

• • The trailer is equipped with solar panels mounted on a metal chassis, supported by off-road tires for rural terrain.
• • Solar energy is captured and stored in onboard batteries, providing consistent power throughout the day and night.
• • The design is modular and compact, allowing it to be easily transported using vehicles with tow bars.
• • The panels can fold down for mobility and tilt at an angle to maximize sun exposure during use.
• • The system is intended for individual ownership and can be deployed in various Dawul Wuru community locations.

💡 Why This Project?

• • To address the need for clean, scalable, and mobile energy in communities with short land tenures.
• • To design an energy solution that respects cultural values and minimizes environmental impact.
• • To apply engineering skills in prototyping, community consultation, and sustainable design thinking.

🔍 Design Process

• • We explored multiple renewable options including wind, hydro, ocean, geothermal, and solar energy.
• • A decision matrix was used to assess seasonality, transportability, cost, and environmental impact.
• • Solar was selected for its affordability, low maintenance, and high compatibility with the local climate.
• • A 3D printed prototype was created to test structure, scale, and mobility features.

📦 Key Features

• • 9x5 ft trailer with collapsible, angle-adjustable solar panels.
• • Durable off-road wheels suitable for rural and wet terrain.
• • Onboard battery storage for continuous energy supply.
• • Designed to be low-maintenance and long-lasting (10+ years).

🌱 Community Impact

• • Provides clean, independent energy to remote Dawul Wuru sites.
• • Enhances quality of life by supporting lighting, education, and healthcare access.
• • Reduces environmental damage and supports cultural connection to land and sea.
• • Offers long-term cost savings and promotes community self-sufficiency.
