- NEW: Webinar: 11 July, 2020 (2:00-4:00 PDT, 9:00pm-11:00pm GMT): Cooking using a Haybox and a Battery Powered Slow Cooker - This webinar, presented by SF Innovations Ltd, will look at two different techniques of cooking using a well insulated cooking container. It will show how to cook rice, stews and even bake bread using little or no fossil fuel. Registration information...
- NEW: 1-4 September 2020: EuroSun2020 is going virtual - The conference will be now be held on a virtual platform, as a response to safety concerns surrounding Covid-19. According to the organization, "We are currently working on new registration fees that reflect the resources and support for creating the virtual conference infrastructure and presenting the conference online. We will provide more details on the registration rates in the coming weeks." The 13th Conference on Solar Energy for Buildings and Industry will offer a platform to discuss the latest developments with leading solar energy experts, policy makers, and industry representatives.

- December 2020: SWC50 – The Century of Solar - In 1970 solar research pioneers met at the first International Solar Energy Society (ISES) Conference in Melbourne Australia. ISES is commemorating this Conference with a special 50th Anniversary Conference and Display, called the Solar World Congress at 50 (SWC50). The face-to-face conference, originally scheduled for 2-4 December 2020, will be replaced by a series of eight virtual conferences over the course of the month in December 2020. It will include the same panel sessions that were planned for the in-person planned event. More information...
- September 2014: Dr. Shyam Nandwani spoke at the Promesa at Santa Ana organization, lecturing on solar energy and productive uses with solar devices and assembled Box Solar Ovens for heated/cooked meals. The objective was to learn how solar cookers and other solar devices could be used for other purposes and the sale of the end product. (For instance, heating sandwiches, making candles, drying herbs, etc., by using clean, free, and abundant fuel - the Sun.) The group now has the basic concepts and some possible uses. They plan to submit a proposal/project to get seed money (around $2,000 USD) to buy some materials and tools to start a small business, and to use part of the income to make the project sustainable.
- August 2014: Professor Shyam Nandwani was recognized by the Energy Globe Foundation for his work as Energy Globe Ambassador for Costa Rica since 2012 and awarded the Energy Globe Silver Medal of Honor.
- November 2012: Solar Ovens used to warm lunches at educational centers - Due to electric rationing imposed by the local Costarican Electricity utility company in January 1979, Shyam Nandwani made the first solar oven for his family in Feb. 1979 to warm the lunch cooked the previous night. Shyam has observed the rising demand for our solar ovens at educational institutes to warm lunches for the students at schools and colleges, etc. According to school directors, the reason for using solar ovens is to reduce the queue for using microwave ovens, as well as to reduce the electric bill for the institute and promote environmental culture for the students (and also for the parents).

- March 2012: After a roughly 16-year hiatus, the Costa Rican Solar Energy Association (Acesolar) rides again, and they want nothing less than to capture the sun. They recently held a demonstration of solar cookers at National University’s solar energy laboratory in Heredia. Much of the lab’s research is geared not toward photovoltaic production of electricity, but toward thermal solar energy – harnessing the sun’s heat that enters our atmosphere and channeling it to some productive end.

Costa Rica has a rich resource in the presence of Indian-born Shyam Nandwani, a Professor of Physics at the University Nacional in Heredia, a city near San Jose. Dr. Nandwani's personal interest and longtime demonstrations of the power of the sun for domestic purposes have been an inspiration to many, not only in Costa Rica but also around the world. He has been a speaker at numerous international conferences, including all of the world conferences on solar cooking, and has been a guest lecturer at universities in Germany and the United States, among others. He is a sparkplug in the coordination of networks of solar cookers, both in Central America and for the entire continent; almost single-handedly, he was responsible for the organization and implementation of the Second World Conference, held at his university. Surely, most Latin American solar cooks and promoters are familiar with his professional contributions.
Another outstanding contribution to the world of solar cooking is a demonstration site at the Universidad Nacional, where an outstanding collection of solar cookers and dryers of many types and varied size and scope, from household to field army, can be seen. Here one can see, touch, and thus understand the use of devices usually only seen in diagrams and pictures. Students in the university continue the research of Dr. Nandwani by working on and testing new designs, making old ones more efficient, and teaching others about the technology.
Dr. Nandwani not only demonstrates solar devices in his laboratory; his home is also a model for all who want to live lightly on the earth. He uses solar cookers (one of which has electrical backup in case of rain), solar water heaters, and even a microwave powered by a photovoltaic cell. The house is a delight to see and visit, a "must" in Costa Rica for solar cooker enthusiasts.
Another major actor on the solar cooking scene in Costa Rica was the organization called Fundacion Costaricense Sol de Vida (Sun of Life). This organization was one of those initiated in Central America by the work of an American, Bill Lankford. The network was known in the area by its Spanish name of PROCESO. More details of this work are given in the section on Guatemala, where the initial and largest project has been underway for some years.
An early activity of Sol de Vida was establishing a celebration La Fiesta del Sol (in keeping with Latin traditions of celebrations), honoring the sun and held annually. It proved to be a marvelous event for publicizing solar cooking, calling attention of many to this technology. It was not an isolated activity but rather an integral part of the larger project, Sol de Vida. In 1999, the organization was awarded the National Prize in Energy ~ Innovative Project for its work. The Ministry of Environment and Energy, the National Power and Light Company, the Chamber of Industries and the Association sponsor that award for the Investigation and Development of Energy and the Environment.
Sol de Vida also created an educational facility, EduSol, to house its promotional and teaching activity. The organization was recognized as an innovator beyond the borders of Costa Rica as well. Sol de Vida was one of the Costa Rican awardees of the Small Grant Program in 2001.
Another Costa Rica project was honored at Johannesburg by the award of the Equator Prize, offered by the same Small Grants Project program of UNDP. Associación ANAI, a local NGO in Costa Rica, promoted solar cookers that enable women to engage in income-generating activities, thus improving their living conditions and reducing the burning of fossil fuels. They reported a strong focus on encouraging women to pass on their knowledge to their children, thus promoting the use of solar cookers into the future.
