Problem
Fuel (eg. kerosene) is usually expensive or unavailable in rural areas, but people need light to do productive activities at night.

Our Approach
To design a lantern or flashlight powered by microbial fuel cells that only need free, locally available organic materials.

Benefit
• • • • • Light for cooking, economic activity, reading, etc. Low capital cost. No fuel cost. Environmentally friendly. Potentially locally-produced -> micro-enterprise opportunity

Market Scalability
• Applications for developing as well as developed countries. • Can replace more expensive forms of lighting. • Usable wherever there is dirt. • Can be mass-produced. • Portable so can be disseminated easily. • Lantern can be the first of many microbial fuel cell applications.

Goals for Summit

• Design and build prototype of either a lamp or flashlight powered by MFCs for use in villages. • Develop a comprehensive maintenance manual and user surveys. • Deploy a few samples of the prototype with IDDS participants to gather feedback. • Develop a business model for dissemination.
