Rocket Stove


Fiji, Cambodia & Timor-Lesté



Project Everest is keenly interested in the use of sustainable fuels in Fiji. In addition to reducing the production of greenhouse gases, more efficient fuel use for cooking and heating can reduce the cost of living and and can improve the health of those who depend on unsustainable and inefficient fuels such as firewood or oil.

Thus far, teams have identified trends in general fuel use and have begun to refine the needs of the community, have ideated and begun to develop prototypes to address the issues.


The aim of this project is to further investigate the issue at the local level, filling in any gaps, formalising the data in the form of a market analysis and continuing to test the proposed Rocket Stove Prototype.

  • Continue collecting primary data on fuel and energy use in the area of operation
  • Continue testing, researching and refining the rocket stove design
    • Quantitative data on results and performance of the stove
    • Village testing and incorporating feedback into iterations
  • Continued researching and testing of the viability of bio-waste fuel briquettes
  • Investigation into the viability of a recycling program to source materials for sustainable and low cost stove manufacture
  • Development of partnerships with potential large-scale manufacturers

The continuation of a business idea in any of the focus areas is not expected. All ideas are assessed at the conclusion of the projects and those deemed to be below the required standard will be discontinued.


The proposed rocket stove aims to reduce the required fuel required and smoke emitted (especially harmful gases such as carbon monoxide as a result from incomplete combustion). It works with all solid fuels such as wood, biomass briquettes and other combustible waste such as animal dung.

Through increasing airflow it ensures that more complete combustion can occur, increasing heat output, reducing production of harmful carbon monoxide and reducing the amount of fuel required.


The rocket stove aims to address multiple issues across health, quality of life and environmental sustainability.

Environmental Sustainability – Deforestation is an issue across the globe and residential use of wood for cooking is a large contributor to the cutting down of trees in developing countries. Removal of trees reduces the Earth’s capacity to process the carbon dioxide released from human activity. Additionally, this “stored” carbon is then released when combusted. Carbon dioxide, methane and carbon monoxide is released in the burning of wood – when inefficient combustion occurs, black carbon is emitted. Black carbon is one of the top contributors to global warming.

Health – Respiratory issues associated with cooking are estimated to result in over 4.3 million deaths per year. Current methods of burning fuels for cooking are inefficient, cause a lot of smoke and production of harmful gases.

Quality of life – The smoke from inefficient combustion also results in significant discomfort during cooking, causing itchy eyes, coughing and carbon (soot) on the walls and roof.

Project Everest is dedicated to helping realise the Sustainable Development Goals. Of these goals, Project Everest has been working on goal twelve, Responsible Consumption and Production: ensure sustainable consumption and production patterns. One component of this goal is particularly interesting to Project Everest; that which relates to consumption of fuels and generation of CO2 in the home.
