Kosher Technology

Shomer Halacha, Shomer Shabbat

This page is intended to give a selection of some technical artifacts whose design and function permits the observance of Halachah whilst simultaneously providing a benefit, e.g. heating food on Shabbat.

Also included are a few items which raise Halachic questions which are not linked to Sabbath observance.

Some others, e.g. water filters, are similar to foods in that their manufacture is subject to Kashrut laws. One does not expect to eat a water filter but if the filter material contained chometz then the output would be suspect. Elsewhere, I read of a brand of poisonous drain cleaner which had a Kosher L'Pesach Hechsher. The intention was apparently to guarantee that it did not contain Chometz and could thus be owned by Observant Jews during Pesach. Another interesting application is that of a brand of kosher, Hechshered olive oil intended for Sabbath lights, Nerot Shel Shabbat, but prohibited for consumption as food.
