TEG Project

From The Collaboratory

Jump to: navigation, search

In a recent study, it was found that nearly 2 billion people worldwide use open cook fires for common purposes such as making food and boiling water. Women often cook using open fires every day to provide the family with food, but what they don't realize is that the harmful products of burning biomass that settles within the household due to a lack of proper ventilation has been linked to various diseases including pneumonia in children, Chronic Obstructive Pulmonary Disease, asthma and other lung and heart diseases. Unfortunately, the harmful byproducts don't stop at causing those health risks. It was found that open cook fires steal the lives of nearly 1.5 million people a year.

Because of the increased need for a proper ventilation system, we hope to use a thermoelectric generator to convert waste heat from the cook stove to electricity which can power a fan that will draw smoke from the fire through the filter in the ventilation hood. The reusable filter will be used to eliminate most of the carbon particulate from the smoke. This smoke is then extricated from the household using a duct. We hope to build a hood that is as unobtrusive as possible and is adjustable to accommodate various cook fire sizes. The TEG could be contained in a modular metal housing adaptable to various surfaces. The surface of the module should be designed to interface with a heat source whether it be coals, pots, pans, etc.


Purpose statement

"As each has received a gift, use it to serve one another, as good stewards of God's varied grace" 1 Peter 4:10

Our purpose is to use our knowledge of Thermoelectric generators to improve the quality of the environment in which families who use open cook fires can live in. Through this project, we hope to use our abilities and resources to externalize God's love for us through our service - sharing the hope of Christ.


2013-2014 Semester goals

  • Begin Construction of Initial Prototype
  • Test various heat sinks; Determine which works best
  • Experiment and develop observations on current TEG efficiency and how to improve it
  • Improve Smoke Detector Circuit
  • Develop a battery system

Year goals

  • Build a battery-operated prototype model of a Ventilation system
  • Refine design to streamline shipping
  • Keep in contact with Client and keep specifications up-to-date
  • Go to Oaxaca and implement our system

Long term goals
