Quick explanation: In orthodox judaism, one is not supposed to operate a light-switch on the Sabbath.

I'm not jewish, but some of my friends are observant (but progressive) and use the Sabbath as a day of reflection. This seems to completely go against the spirit of the rule (to spend a day living simply with friends and family, without technology for maximum reflection, introspection, and rest).

I don't see how this gadget would catch on -- unless someone is bound is follow the rule to the letter, but doesn't really want to (but then at that point, they should just stop adhering IMHO)

I am Jewish.

So I can tell you that you are 100% right. I don't think this is really going to catch on for that very reason. Sabbath is a day set aside for family, religion, and not working.

I think what the main use is going to be is people will install it for emergencies. So I'm sure in Israel a lot of people will put it in their bomb shelters so if they need to spend Sabbath in the shelter and need to use the light, it won't be directly going against Sabbath.

> will install it for emergencies

Surely use in emergencies is allowed already.

That is true. If any ones life is in danger, your supposed to "forget" the Sabbath right away and do what's necessary. But, for example, if your wife is very very pregnant and can give birth over Sabbath, if she goes into labour on Sabbath, 100% you HAVE to driver her to the hospital. But it's better if before Sabbath you order a taxi.
