  9. Requirements

  10. Market Survey (from Score Project 2007) Nepal survey (results confirmed in Kenya) Yangalot village in Hagam Husband see chart on next page Wife better cooking position low smoke better education for children Business case Household: 70p per month saved on kerosene for lighting, Score pays back in < 3 years Village shop sells and maintains score to offset kerosene sales. Country carbon credits cascade manufacturing. Now 2- 4x

  11. Market Survey (from Score Project) • Typical Nepalese house • Target cost* • Between £20 and £60 • In large quantities enables • 1.2 B to 60 M people • BUT………………………….. * 2007 prices

  12. Affordability • Cheapest solution is not the most affordable • The right packaged solution makes it more attractive. • Stop using kerosene for lighting. • Torches etc. mean kerosene use > zero • Typical kerosene cost = £15 to £30 pa • Use of LED lights, low maintenance, • cost decreasing due to learner curve. • Need easy-to-use way to monitor electricity • So that carbon credits can be claimed. • Low cost entry point uses low capacity battery. • Many devices (mobile phones) can be charged during cooking • Total Package now aimed at £100, with micro finance

  13. Generating stove goals • Reduce • Wood consumption • Smoke inhalation • Improve • Health • Reduced smoke • improved understanding of modern medicine • Preservation of prescription drugs (cooling) • Education, by means of electricity • light at night • access to knowledge through mobile phone and computer • Radio and TV • Wealth • Better education • Access to improved farming methods and commodity prices • Business opportunities (sales and maintenance, selling electricity)

  14. How to make it happen

  15. Strategy Score Centres Malaysia, NepalBangladesh, Jaipur, Kenya, Uganda Local community engagement Score Core Team Researchdisseminationcommercialisation Score Community 21 Collaboration agreements Score Partner organisations Intellectual property given free to developing countries, in return for Score owning improvements. Licenses available for developed world

  16. Is Score useful? • Simulated Score Stove • 35 houses in Nepal and Kenya • 10 – 20 W electrical • No smoke, less wood • Satisfaction • 100% used electricity for lightinghelping education, social • 80% used for radio • 33% mobile phone charging • 16% sold electricity • Interest from Developed world • KTP with Warrior Stoves (UK) awarded • CHP Benefit can be gained from as little as 15We, longer term 100We targeted.

  17. Technology options • There is no doubt that a reliable smoke-free cooking stove that generates electricity, reduces fuel consumption and is affordable, will sell in the 100’s millions and give great benefit. • What technologies can meet these requirements? • Erikson cycle • Stirling engine • Steam engine • Solar plus clean cooking stove • Thermo-Acoustic • Thermo-Electric (Thermopile)

  18. Score Status April 2012 Thermo-Acoustic technology chosen Research phase and dissemination completed Additional awards made (totalling £0.5M) KTS, KTP, centre establishment, Follow on funds. Significant free support (people’s time) Score Community running since 2008. City University achieved record of 23We for wood burning TAE. 37W on rig Scientific (instrumented) rigs built Leicester and Queen Mary University of London 10 demonstrators built, 6 on order Cost reduction plan One off demonstrators £2500 in UK, £750 with low labour cost, In 100k pa volume £150 RR audit, £60 with manufacturing improvements More research needed to hit £20 target

  19. Social requirements

  20. Key social findings Smoke repels insects, if it is removed, they return There is a belief that termites will eat their house Local knowledge is essential when designing Some people like to make illicit alcohol, if the still does not fit, the stove will be rejected. If there is no-one to fix a broken stove, it stays broken Respect the village hierarchy Asking the question the right way from the right person is essential to getting the right answer. Do you want to cook in squatting position or stood up? An electrical generating stove gives incentive to change to the whole family.

  21. Business requirements

  22. Business Case model • Available on memory stick is an Excel™ model • The model shows a business case at 3 levels • The Household • Village Store, or shop • Country or large region • Pico Hydro • Is cheapest solution, where available • Falls behind at regional level as coverage is limited • PV solar • Needs to operate in monsoon season (reduced light) • Needs smoke free stove as well • Assumptions • Can be varied to benchmark different scenarios and technologies • Are designed to show consistency across different options • Feedback from your technology area is welcome

  31. Score Objectives Contribute to increasing wealth and education and improving health in developing countries by investigating appropriate and affordable novel technology to meet the energy needs of isolated rural communities in developing countries. This technology is designated, SCORE, the Stove for Cooking, Refrigeration and Electricity supply. Develop a Project Network, comprising academics from both the research team and local universities acting as knowledge hubs in the target countries, charities and non-government organisations, government representative and the local communities themselves. Exchange and focus the scientific, technological and social knowledge required by SCORE. Promote SCORE worldwide and provide a database of end-user requirements and product applications Plan and create the mechanisms for implementation of SCORE by identifying barriers to implementation and proposing solutions, forming collaborations within the developing countries, developing training strategy and suitable training materials, encouraging the acquisition of matching funding, promoting the building of local manufacturing capacity, and highlighting the wider business opportunities of SCORE in developing countries. Capture and evaluate the underpinning scientific knowledge of thermoacoustic technologies and devise a new engineering concept combining the thermoacoustic engine, electrical generation and refrigeration. Integrate these in a technology demonstrator. Study heat transfer processes in combustion and thermoacoustic systems and devise a high-efficiency, integrated combustor/heat exchanger/stove unit, capable of fulfilling its cooking function and providing the energy to the thermoacoustic element. Evaluate its performance by experimentation and integrate it into a technology demonstrator. Devise through interdisciplinary research an inexpensive method to convert acoustic energy into electricity that could be easily mass produced and evaluate its performance. Study the manufacturability, cost and the potential of using indigenous materials and local skills and based on the technology demonstrator, to design feasible SCORE prototypes, which could be field tested at selected locations. Build and demonstrate the prototypes in selected rural communities. Benchmark the design against other technologies and recommend future development paths, research and applications.
