Thesis Direction
Decreasing Cost
Howdo youmake it
cheaper?
• share the cost• decrease cost of materials & production• decrease cost of installation & transport• Increase the opportunity cost

Who Benefits and How?The Consumer• Reduces cost of digester• Reduces cost of waste removal• Provides clean cooking fuel• Extends duration of electricity
The Community
• Captures lost tax revenue• Improved health conditions• Cleaner more attractive city• improved access to electricity• reduced deforestation• reduced greenhouse gas
The Power Company
• Increases adoption of electricity• Gets people using more electricity• Creates a saleable commodity in the form of carbon offsets• Positions firm as an electricity broker• Reduces need to generate power
The Manufacturer• Outsources production• Concentrates on higher value activities, marketing & promotion• Partners with Power Co. • access to distribution network• Single B to B Client
