Recent News and Developments

Beginning at ancient times, Israel has a history of developing solar heating, with a law to have solar heat collectors for hot water on every building. In fact more than 83% of houses are with solar water heating installed on the roofs. Luz, one of the largest solar heating companies in the world in the late 80's until 1999, and today two of the largest solar heating energy companies in the world, are both located near the city of Beit Shemesh (meaning in Hebrew: The House of the Sun): Sollel and Luz II. Also a large portion of the Weitzman institute consists of one of the largest solar collector tower and basin in the world.

Solar cooking has recently become quite common, but in some places like the city of Eilat, there is no need to do anything, and frequently every summer, when temperatures reach 40 degrees celsius and more, the news show how people fry an egg on a car's roof.

In recent years solar cooking has become more prevalent, and in almost all Hebrew and English forums that deal with sustainable systems, there are requests and sharing of information, with new blogs and websites dedicated to the subject. Climatic circumstances are near ideal, and various initiatives including government sponsored advertising. Call (in Hebrew) for Israeli citizens to use solar ovens.</ref> and NGOs have been advancing solar cooking. Rachel Andres the Bronfman prize winner and originator of the solar cooking initiative in Darpur, was closely followed by Israeli media, with this project involving many Jewish communities worldwide. The images in the Israeli media, as well as the article content, left the impression that this was an Israeli project...

It seems that the invention of using a car sun-screen as solar cooker originates from Israel Hebrew site, possibly the original source of this idea, but the site may have been translated. There are no names listed. .

National holiday public festivals are now having public solar cooking as a standard activity, summer camp solar cooking activities are prevalent, with news reaching the media about a young man inventing a new type of solar cooker (see Reports section).

Various companies and research laboratories are still looking into improving solar ovens. (See Research section)

Research

The National Physical Laboratory of Israel (NPLI) in 1996 experimented with the building of a solar concentrating type cooker. The design and materials used created an efficient cooker.

The promoting group was initially operating on the assumption that any solar cooker should lend itself to construction in local villages, largely around cost issues - that is, the intent was to serve the poor of the nation. That goal put considerable constraint on the venture, leading Harry Tabor, author of an article in the proceedings of the Varese Conference (1999), to suggest that while the appliance could be made or assembled locally, the critical elements could only be made in central shops (or even overseas). The NPLI research was limited to parabolic cookers, but the article argues that the principle pertains to box cookers as well. As example, glass cut to appropriate size(s), reliable and weather resistant hinges, bright aluminum in sheets, etc. could be prepared in regional workshops, while the insulation materials, wood, paint could be purchased locally.

Several companies and universities are continuing research on improving the solar oven, notably among them are the famed Weizmann Institute and Schatz Laboratories for Solar Energy Development.

The History of Solar Cooking in Israel

Solar cooking has been mentioned in Jewish holy scripts of the Mishna (compiled approx 200 BC to 100 AD) Hebrew reference to the Mishnaic and Talmud discussions on solar cooking on the Sabbath day (Saturday), stating that cooking done by the sun is permitted on the Sabbath, and are "produce of the Sun, not produce of man-made fire". Today orthodox Jewish ritual discusses this at length, and certain orthodox Ashkenazi Jews many times use the sun as a solution for warming lunch at noon, which otherwise would be prohibited according to their customs. This is only for dry foods, and only if directly from the sun rays and not by passing the warmth from some other material (such as warm sand).

A recent Canadian visitor to Israel, Randy Shulman, lived in a southern remote kibbutz for some months, where she attempted to introduce solar cooking to her hosts. The work is only recently concluded and no word has been received of results.State of the Art of Solar Cooking by Dr. Barbara Knudson.]

The turning point may have been widespread advertising in all newspapers of a family in Netanya, who learned solar cooking from Swiss friends around the year 2003. Israeli solar cooking family in Israeli news. Possibly the turning point for widespread solar cooking in Israel

It is now quite common to see solar cooking at many settings in Israel. (See recent developments, above)

Jewish and Arab cooperation in solar cooking

In Israel there have been several joint initiatives, for learning and practicing solar cooking, especially notable was the northern Israeli religious Jewish Kaditha village solar cooking outing, with Arab teachers from Gallilee, and Palestinian teachers from the Palestinian National Authority studying and then successfully taking it to their communities.

An initiative to bring solar cooking to Bedouins (nomad Arab tribes in southern Israel), was started by Devora BrousFounder of Bustan NGO, angry at Israeli government attitude and actions towards the Bedouins. These Bedouin tribes are at a dispute with the Israeli government and Jewish establishment on land ownership in the Negev desert area. Bustan a grass-roots NGO is still working with the Bedouin people and solar cooking is used as an alternative to the traditional small fire cooking, as well as being a solution for villages not connected to the electric gridhttp://www.amin.org/look/amin/en.tpl?IdLanguage=1&IdPublication=7&NrArticle=42947&NrIssue=1&NrSection=3 Israeli Jews and Arab Bedouins solar cooking project]

Israelis have also participated in teaching Palistinians in the Palestenian Authority about solar ovens, and solar cooking activity. This is usually part of Anti-Israeli establishment activities.

Climate, Culture, and Special Considerations

In the south and eastern desert areas, including cities such as Eilat and villages such as Ein Gedi, temperatures typically reach 40 degrees in the summer days. Solar cooking can be done in these regions on any dark (or sometimes even white) metal or sand. Soldiers and bedouin nomads are known to fry eggs or warm up cans of food directly in the sand, and residents of the cities in these locations, especially in the Arava area, may cook a meal, simply by placing it in the sun, without any solar oven.

In all of Israel, cloudy days account for only 40% of the year at most. In recent years there has been a haze caused mainly by dust from construction with rock covering for most of the buildings, and by polution mainly from transportation. Even so, conditions in Israel are ideal for solar cooking most of the year.
