I found the MPower/TEG stove Cookstove is a stove that has been developed by Irish engineers at Trinity College, Dublin. This stove has been developed as an inexpensive low cost cookstove that can double as a charger for mobile phones, LED lights, radios ect. The stove uses biomass (twigs, sticks and corn husk) efficiently to produce the electricity using thermoelectric generator. The stove has been trialed in Malawi and the design has been adapted to better suit the Malawian people.

 

Each stoves helps to

-       reduces smoke, soot and ash

-       decreases deforestation

-       improve respiratory health

-       charge LED lights, mobiles and other small devices

 

This project is an open source project with the aims that the stoves can be constructed and sold locally. We are looking into possible of our team developing a prototype of a similar stove.

Thermoelectric generators are a fantastic idea, however a lot of work is required to improve their efficiency. Can you help us by posting ideas of ways in which we might arrive at a more efficient thermoelectric generator or thermoelectric generator array?

Hi Kristy,

This is a great idea. The July17 Fuel Team was introduced to this area by Cris Birzer who is a Senior Lecturer in Sustainable Energy Engineering from The University of Adelaide. We have looked into it's implementation on a cookstove similar to the µPower Stove. The TEG stove is a more polished design aimed at a higher economic camping market, similar to BioLite, (https://www.bioliteenergy.com), which we have also looked into.

This would be great for adding appeal to our product and utilising heat waste and reducing energy costs in village. The rocket stove design we came up with has an internal combustion chamber and insulation layer outside which could be used for a temperature differential. In Ideation, we decided not to prioritise this as an option primarily due to difficulty in implementation and low health risk mitigation.

We documented all our research and decision making and will recommend further teams consider this as an option. The open source electronics will be really valuable in that effort. We see difficulties in;
- Cooling
- Cost
- Durability (Waterproofing)
- Component replacement

We are quite interested in potential for improvement with nanotechnology and want to follow that research closely. The link for indigogo you posted is broken but I've found a new version and their Facebook page. If you or anyone finds any more information or examples of applications in rural villages please post.

Activity has died off on this thread and so we are working on slimming down ideas for the upcoming activity.
