Toyola Energy Limited has been making efficient charcoal burning stoves, and selling theme in markets and door-to-door by Toyola “evangelists”, individuals who record each sale in a notebook and then are paid on commission. With 50,000 stoves projected to be sold this year and double that possible in 2010, the paper records are becoming increasingly difficult to maintain. Over the past six months Michael has been working with Toyola and E+Co, a US-based non-profit investment company investing in Toyola, to develop an SMS-based recordkeeping system for their stove sales.

CO/CO2 Ratio in the Charcoal Stoves Tested at Aprovecho (pdf)
Dean Still, Aprovecho Research Center, June 23, 2006

The following graph plots the levels of CO and CO2 during one test each of the charcoal burning rocket stove and Jiko-type charcoal stove from Ghana. A higher level of CO2 suggests a higher burn rate of fuel.

It can be seen that even though the CO level for the rocket drops below 10 ppm, the CO2 level remains high suggesting a high firepower continues. The Ghana charcoal stove has a lower level of CO2 with a considerably higher level of CO.

Comparing the Charcoal Burning Rocket and Jiko Stoves (pdf)
Dean Still and Nordica MacCarty, Aprovecho Research Center, June 22nd, 2006

The charcoal Rocket Stove was compared to the Jiko-type charcoal stove sent from Ghana. 600 grams of Kingsford charcoal was placed in the stoves under the Aprovecho emissions hood. One test was performed on each stove for preliminary studies. The stoves are compared in the following graph for carbon monoxide emissions during a cooking task (to boil 5L of water and simmer 30 minutes).

Practical Action Boilng Point Issue 50 2005

Please read the whole article for the details. Every tips has great detail that will save you hours of work.

The premise: in creating a successful stoves scale up - you need to create a supply chain of successful stoves manufacturers and retail businesses, as well as people who will be able to maintain and fix the stoves (even when they are imported from elsewhere).

the tips:

  • Don't tell the customer that you are from an NGO
  • Know your customers and their habits
  • Copy good ideas from the private sector - e.g. manufacturing, branding and marketing tips
  • Give the stove status and style
  • Balance demand creation with supply
  • Pay attention to quality control
  • Treat your retailers well
  • Pay your sales agents on a commission basis
  • Beware of projects bearing your stoves as gifts. This undercuts your hardworking retail outlets
  • Use your stove on a regular basis, using your stove to cook on will help you educate your customers and improve your stoves
