|Solar Cookers International and the International Solar Energy Society began the process of creating an open-source solar cooker testing program called the Performance Evaluation Process (PEP) under the direction of Dr. Alan Bigelow. The project involves establishing a uniform method of testing, and then providing information for interested parties to build their own testing station.|

- April 2018: Solar cooking in Puerto Rico after Hurricane Maria - In February and March, MSA Renewtech Foundation (India) and the United Clergy Task Force (UCTF) (US) responded to requests from ten faith-based communities in rural Puerto Rico for community-sized solar cookers. With private funding, coordination by UCTF, training by Mr. Pranav Gadhia of MSA Renewtech, and bilingual technical instructions, curriculum, and survey tools from Solar Cookers International (SCI), ten faith congregations of more than 100 people each are being trained in the assembly and use of the PRINCE-40 parabolic dish solar cooker in rural Puerto Rico. In late April, Ms. Anne Patterson, an SCI Global Advisor, will deploy 25+ Solavore solar ovens from Punta Santiago to the Toro Negro rain forest and Morovis. Most of these places are still largely without power and families spend a lot of money on fuel for generators. Monitoring and evaluation are incorporated into this project to track results. The evaluation tools used in these projects can be downloaded from http://www.solarcookers.org. Also available in Spanish from SCI.

- June 2017: Solar Cookers International (SCI) launches pilot solar cooker testing centers in California and New York - The purpose of this pilot project is to check the repeatability, reliability, and reproducibility of results from SCI Performance Evaluation Process (PEP) testing stations for solar cookers, irrespective of location. SCI’s pilot testing centers are located at different latitudes and at different elevations. The two locations also experience different weather conditions. The solar cookers, the cookware, and the testing instrumentation, however, are the same at both locations. This pilot project is testing sets of three types of solar cookers: reflective-panel cookers, box ovens and parabolic reflectors. The PEP results provide cooking power measured in Watts, which is only one of many ways to evaluate solar cooker performance. In June, weather conditions at SCI’s pilot testing centers are well suited for testing solar cookers according to the ASABE S580.1 protocol for Testing and Reporting Solar Cooker Performance. This protocol requires that outdoor ambient temperature must be between 20 - 35 °C (68 - 95 °F). This temperature range is generally available at both SCI pilot testing centers between the vernal (spring) equinox and the autumnal (fall) equinox. Testing days within the required temperature range should also be clear days with consistent solar energy. SCI welcomes others to join this pilot solar cooker testing project to validate the reproducibility of the SCI PEP testing stations. By using the same instrumentation, results have a consistent format for data comparison. Potential project partners can access the assembly manual for the SCI PEP testing station, available as open-source content online at SCI’s PEP web page. To join SCI's pilot solar cookers testing project, email firstname.lastname@example.org

- June 2015: Solar cooking meets the tech community - Chef José Andrés invited Kirk Smith, a Professor of Environmental Health Sciences, at UC Berkeley, USA, to join him at a panel discussion for environmentalists challenging the tech community held in Silicon Valley, California. Dr. Kirk has discounted solar cooking in the past, but now feels it is a viable part of the clean cooking solution to help preserve the environment and improve the health of the many cooks cooking over open fires. Dr. Smith and Andrés called on the audience to go back to their employers – the technology companies of the Bay Area – and apply as much innovative thinking to clean cooking as has been applied to electric cars and evolving the jet engine. Delicious solar-cooked mushroom tacos were prepared on the grounds outside of the conference. More information

No precise numbers are available, but estimates suggest that perhaps as many as 10,000 Americans use solar cookers regularly. The electrical utility of the Sacramento, CA area, the Sacramento Municipal Utility District (SMUD), has been a strong supporter of solar energy usage. SMUD serves an area of more than a million people. Under earlier leadership, it pioneered the development of cleaner electricity generation, including building the first solar-powered generating station in the United States. It has offered rebates for replacing old appliances with energy-efficient equipment, and it cooperated in planting trees to lower the cost of air conditioning to consumers, as examples. For purposes of this report, it is important to note the strong support of SMUD for solar cooking education, including outreach to schools and community organizations. They have placed solar cookers with Scout troops, offered workshops in 65 schools of the area, and made available plans to build cookers to customers throughout their service area. In 1991, SMUD even produced a solar cooking cookbook. Reducing the use of electricity is in everyone's interest; this interesting example of a public utility's contribution to solar cooking as one contribution to solving the problem was noteworthy.
The late George Lof, a former director of the Industrial Research Institute at the University of Denver, Colorado, was an early pioneer of solar-powered technology, including solar cooking. In the fifties, he experimented with a parabolic solar cooker design that he dubbed the "Umbroiler" because of its umbrella-like structure. He marketed the design, but it was a commercial failure for the times.
Considerable activity can also be found in the state of Arizona, probably the sunniest of the U.S. fifty states. The most important solar cooking fact about Arizona is that the late Barbara Kerr, the foremost expert on solar cooking in the U.S., lived in a small community in this state. She created and lived in the Kerr-Cole Sustainable Living Center, which demonstrates a wide range of ways to live lightly, rather than destructively, on the earth. Barbara is the author of several books (The full text of one is here) and articles on solar cooking, the creator and marketer (with her colleague, Sherry Cole) of a cardboard box cooker, the refiner of the CooKit as the first inexpensive but efficient solar cooker, and a never-ending source of information to those who seek her knowledge on the internet. A visit to Taylor, Arizona, is a trip to an important piece of solar cooking history.
Solar devices are also manufactured in this area. Early pioneers, the late Bob Larson and his wife Heather Larson, produced cookbooks and plans for solar dryers until their untimely deaths. Jay Campbell, a New Mexican engineer, has invented a range of cooking devices that won prizes for ingenuity and efficiency, though he is not a manufacturer but rather an idea person. One firm, Zone Works, makes and sells parabolics out of Albuquerque, NM.
Unlikely as it may sound, the state of Minnesota has also made contributions to the development of solar cooking. Mike and Martha Port, founders of the Solar Oven Society, have worked in a variety of Central American and Caribbean nations on various projects. Recently, they completed research and development of a new cooker, manufactured from recycled soda bottles; the device will help to fill the gap between the very inexpensive (but not so long lasting) CooKit and the more expensive box or parabolic cookers. With the assistance of a small business development grant from the State of Minnesota, charitable contributions from a range of churches and organizations, and the dedicated volunteer labor of the Ports over many years, they have recently been able to begin the sale and marketing, both in the U.S. and abroad, of the Sport. A collectivity of Minnesota churches made possible the shipment of 400 unassembled cookers to Afghanistan for sale at a subsidized price to people whose need for cooking energy is great.
The Sacramento, California NGO Solar Cookers International, the sponsor of this Wiki, has worked since 1989 to promote solar cooking around the world.
