Solar Cooking
Last edited: 10 November 2020      

Leéiyen teaches the use of solar panel cookers and the SODIS method as well as water pasteurization in Cameroon, November 2014.

Engineers Without Borders - Sweden is being represented by Stefan Karnebäck, an engineer and former educator at KTH in Stockholm, Sweden. He has developed a water disinfection project in Cameroon. Two main methods are being presented, water pasteurization and SODIS, They have partnered with the Afoni Children of Hope Foundation (Acohof) in Tatum setting up a small-scale development and information center, DevICe, in the northwest region of Cameroon.

They have an interest in the development of standards for the testing of the performance of solar cookers. The ASAE S580 from ASABE will be used at DevICe in Cameroon.

Engineers Without Borders - Sweden is running projects in many countries on a voluntary basis. The projects are organised in different technical focus groups. One of these are named "Sustainable Food Production and Processing". The diffusion of integrated solar cooking is of prime interest for this group and a number of activities will take place in the near future.


  • June 2021: Pete Schwartz presents at an Engineers Without Borders- Sweden hosted conversation

Insulated Solar Electric Cooking with Thermal Storage, EWB Sweden, Pete Schwartz, Cal Poly Physics-2

Pete Schwartz presents his team's latest findings, as they develop different approaches to insulated solar electric cooking. He predicts an eventual decline in the use of phase change materials (PCMs) to retain the heat for cooking, as batteries become a more efficient and less expensive way to store energy. This may happen in the next ten years. In the meantime, a solid block of aluminum is showing promise as a simpler way to store heat compared with PCMs.

  • November 2018: Kitchen Facility with Rocket Stoves in Ghana - Engineers Without Borders are constructing a new kitchen at Wulugu Senior High School in Ghana. With the new kitchen solution through the use of multiple Rocket Stoves, teachers, workers and children at the school will be able to continue their everyday life without inhaling any smoke that causes health problems.
  • February 2016. DevICe is moved to Acohof Family Farm School (FFS), still in Tatum. The staff contains old members, teachers at the school and some journalists at Acohof Community Radio. In this way the students at the school will be involved and te message can be spread on regular Radio Broadcasts.Several schools in Tatum have started to practice SODIS.
  • February 2015: A Development and Information Center, DevICe, has been established in Tatum, Kumbo, north of Bamenda in Cameroon. After two weeks of training, the staff continues to test different types of solar ovens, provide information about water hygiene, and help with simple water quality analysis. They will also look into solar cooking. The center is run by voluntary work with a small budget. However, they are able to use a professional pyranometer from Kipp & Zonen. The project is run in partnership with Engineers Without Borders - Sweden, and sponsorship by Inpsecta, a technical consulting company in Sweden.
  • February 2013: Engineers Without Borders - Sweden did an evaluation of a solar cooking project that the group had implemented in a refugee camp in Tunisia in 2011. They found that there had been no significant uptake of the technology and that the refugees mostly cooked with LPG. More information... - (English version)
