JERUSALEM -- Israel's national electric company is facing a religious quandary: How can the Jewish state's power supplier generate electricity on the Sabbath without violating the laws of the Jewish day of rest and prayer?
To find an answer, the multibillion-dollar company has turned to the shabby offices of Rabbi Levi Yitzchak Halperin, a 72-year-old spiritual adviser with a Father Time beard, who is widely recognized as the final word on what is possible and what is not under Orthodox Jewish law.
Jewish law provides a guide for the actions of observant Jews from morning until night. Prohibited activities on the Sabbath include working, using most forms of transportation or flipping on a light switch.
Halperin and his team of religious scholars, engineers and scientists work to find answers to the challenges that the fast-paced, technology- dependent world creates for Jewish law.
"What we do is show that the Torah is a living Torah, a universal Torah, an eternal Torah, and therefore includes everything in it. The Torah is the blueprint of the world. As such, one finds in it guidance for life and also modern, technological society," said Halperin, director of the Institute for Science and Halacha, or Jewish law, in Jerusalem.
Much of the institute's research is dedicated to dealing with the challenges presented by the Sabbath prohibition against lighting a fire, which Orthodox Jews interpret as preventing them from completing an electrical circuit -- dialing a telephone, pushing an elevator button or turning on a coffee maker. Some institute solutions are quite simple, such as a Sabbath light, which is nothing more than a fluorescent bulb with a metal cover. The light is turned on before the Sabbath and the cover opened and closed as light is needed. Elevators can be programmed to stop on every floor automatically so that no buttons need to be pushed. The institute developed a special telephone that can be dialed without completing a circuit.
Other problems required more complicated solutions. How can doctors, nurses and others who must work on the Sabbath take notes but not break the law against writing on the Sabbath? A pen with disappearing ink. Because the notes are not permanent it is not considered writing under Jewish law.
The institute's 23 staff members spend much of their time responding to callers from Israel, the United States and around the world who have questions about what type of fish is kosher, where they can buy a Sabbath-friendly telephone or how Jewish law applies to in vitro fertilization and organ transplants.
Lately, institute staff members worked overtime before the Jewish high holidays, starting with Rosh Hashana -- the Jewish new year -- which began Friday. Many Jews, Orthodox and secular, develop a heightened interest in Jewish law and traditions around the holidays, staff members say.
The question posed by Israel's electric company is one of the rare cases in which the institute does not have a solution on file. On the Sabbath -- from sundown Friday to sundown Saturday -- some electric company employees must tend the coal-fired power plants. But many members of the ultra-Orthodox Jewish community believe the state-run corporation should not break Sabbath rules. To distance themselves from the power company, some ultra-Orthodox communities such as Mea Shearim in Jerusalem and Modiin Illit in the West Bank have broken away from the national power grid, using private generators on the Sabbath.
But the Israel Electric Corp. is looking to win these customers back, searching for a way to produce power on the Sabbath within the guidelines of Jewish law.
"We operate the power stations so the number of workers is kept to a minimum. But there are certain members of the ultra-Orthodox community that don't accept it, and that's why we are looking for solutions," said David Golan, a spokesman for the utility.
Halperin is looking for ways to automate the work on the Sabbath. He hasn't found an answer yet, but says he is confident that one will be found that will satisfy electricity producers and Jews who adhere strictly to Jewish law.
A minority in Israel strictly observes all the Jewish laws studied at the institute. Many Israelis drive on the Sabbath and never worry about eating kosher. Still, the Israeli government, which helps fund the institute, says that secular Jews take an interest in observing certain Jewish laws.
"There is a large movement of people coming back to roots and religious observance, and they are looking for traditions, and the institute is where they can come for guidance in those traditions," said Yitzhak Cohen, Israel's minister in charge of religious councils.
Searching for loopholes in Jewish law might appear to be little more than theological hairsplitting. But institute staff members say their goal is not to find ways to circumvent divine laws so that Jews can watch television or drive on a day meant for family, quiet and prayer.
