This work of these two women inspired the formation of Solar Cookers International. A few years later, the organization, again with the technical assistance of Barbara Kerr, pioneered the introduction of a different type of cooking device, the panel cooker, a hybrid between box and parabolic. This invention was a breakthrough, as it was less expensive and thus able to serve the needs of the world's poorest inhabitants.

Coincidentally, on that day the United Nations declared that the world population had reached five billion people just 13 years after it had reached four billion. The new organization declared then that at least one billion persons could benefit from knowing how to cook with the sun. Obviously, the organization has been required to up its goals routinely, as the world's population has continued to burgeon, to well over six billion in , meaning that today the target group is over two billion.

Of some historical interest is the fact that before the founding of SCI in , a major demonstration of solar cooking was supported in the Bolivian highlands, an area where wood was already scarce. Two organizations, the then Pillsbury Corporation and a non-governmental organization called Meals for Millions, jointly sponsored demonstrations of cooking and later taught villagers how to build ovens with local materials.

In , Pillsbury, in cooperation with Foster Parents now Save the Children sponsored a similar project in Guatemala. These projects were among the early nation-to- nation projects, starting a long stream of such projects around the world that continues to flow today. Since that time, numerous other organizations have been formed to sponsor projects and promote solar cooking activity.

Their work, as known from written documentation, is detailed in the chapters, which follow. This thumbnail sketch is only a small part of the history, much unknown even to solar cooking supporters, of the many men and women who have caught a glimpse of the potential of the sun to cook food and have attempted over the centuries to spread that knowledge to others who can benefit.

The parabolic style solar cookers use parabolic surfaces, or curved mirrors, to concentrate the sunlight to a focal point. The panel style cooker involves multiple reflectors that are arranged to focus sunlight onto a pot or other device. Although there is a lot of variation between designs of solar cookers, in general they all fall under three categories: box, parabolic, and panel.

The box style is the most prolific, due to its decent efficiency, ease of use, and price. The parabolic style tends to be more effective, reaching higher temperatures and faster cook times, but is expensive and requires frequent adjustments. The panel style cooker can be very cheap and easy to build, but often are not as effective as the other models.
