Kashrut Technology

Yes, but that would still make such a product less marketable.

Let’s go through the issues with mass marketing such technology. First, we have to figure what the cost would be to develop the product, and then to produce and install it. I don’t have a number, but it would probably be expensive on both ends.

Then we have to figure how many people would buy it. I don’t specifically know that either, but we can eliminate many. We can eliminate anyone who has a dishwasher. We can eliminate anyone who has two sinks. We can eliminate anyone who, despite having one sink and no dishwasher, doesn’t generally leave their dishes to pile up. We can eliminate anyone who is uncomfortable with washing milchig and fleishig dishes together in hot water, one factor being that it’s not l’chol hadeios.

Figure that most homeowners have either two sinks and/or at least one dishwasher, and figure that most people would probably not invest the hundreds of dollars it would probably cost into a rented home.

I think there’s no money to be made on such a product, so nobody developed it. Shabbos clocks, on the other hand, are not even a specifically Jewish product, and they serve a more important and widely useful function. Even the Kosher Lamp, which is marketed to shomer Shabbos people, is more useful, and more affordable, to a much larger group of consumers than would be a kli shlishi sink, in my opinion.

The “Kosher Lamp” is no great invention, You can basically do that yourself. Make a Lamp and then cover it at night. Make sure you use things that do not burn

Maybe not a great invention, but a fantastic innovation. What you can basically do yourself, they put together into a marketable product.

Lol, I know what he said, but I don’t think that applies here. I think the Kosher Lamp is more convenient than a homemade contraption.

Internet Cameras are used at milking plants to insure that it’s ??? ?????, and as far as I know it’s also used to save having a ????? ?????

Showering on Shabbos? Ask your LOR if that is allowed.

In our local mikve they actually fill the bor on erev shabbos with boiling hot water, I don’t remember the source for this, nor what is gained, but some poskim do not allow use of water that was heated on shabbos

How does your local mikve heat water on shabbos?

Barlev, I knew someone would ask that. I forgot to add a disclaimer to my post that there are shaylos about bathing on Shabbos even if the water was heated in a halachikly muttar way. Which might be why such a thing hasn’t taken off. But there are circumstances when it can be muttar and it can even be helpful just to avoid the accidental issur of turning on the hot water faucet in the sink. During the winter I often turn on the hot water faucet for general hand washing because the cold water is very cold and the weather is freezing. I have to remember not to do this on Shabbos.

Bump.

What’s the point in a kli shlishi sink? It still won’t make it ???? ??????? to wash meat and milk dishes together. ???? ???? ??? ???? ??.

In general, all of our kosher innovations only work when they are cost-effective solutions to a common problem. (Think kosher lamp, timers etc. they are relatively inexpensive, usually not that much more than a regular lamp or light switch.) Why spend money on an oven that allows you to cook meat and milk in the same oven when you already could if it’s a ??? ???, you could cover it if there is ????, and in most cases you won’t need your oven for both milk and meat simultaneously?
