Stake Holders’ Analysis 12,000 Villagers WVI Appropriate Technology Program Negative: charcoal and fuel wood merchants would be losing income (not in larger WVI community)

Three Major Components of The Solar Cooker http://ecx.images-amazon.com/images/I/61qfKWNJEYL._SL500_AA280_.gif Heat Reservoir Collector simple stove

Thermal Storage Prototype

The Benefits 6-7 hours of cooking time 24 hours day of warming / drying time Smokeless Lets operator stay indoors Lets operator Fry / Sear food instead of bake Separates operator from collector

The Game Plan Stage One Stage Two Stage Three Area Assessment. Angle of solar reflectors to maximize gain Find apprentices (20)/Meet with apprentices Stage Two Gathering raw materials : sand, clay, pumice, bricks and tiles. Procuring mirrors Stage Three Assembly Empowering apprentices Apprentices take over production

Gantt Chart

Grant Proposal : Scope Goals Objectives Create a sustainable solar cooking solution for impoverished countries Ruzizi village would provide a model Improve lives of people in the village by offering alternative to traditional cooking method Objectives Evaluate current and future solar cooking designs Work with WVI to implement solar cooking solution

Grant Proposal: Background Problems Indoor air pollution Deforestation Flooding and loss of crops Challenges TSD and collector cost Solve with available materials TSD peak temperature TSD and collector performance Solve through concept development Stakeholders’ Analysis.

Grant Proposal: Plan of Action Evaluation with decision matrices Three project implementation stages Timeline Assessment Customer satisfaction Firewood usage Indoor air quality Quality of life (time savings) Life cycle cost
