Technically, it should be possible to built a pot that uses the heat from the stove to stir it's ingredients.

You've got a bright future in crazy Victorian inventions if you can make a steam-powered time machine to get there.

At a rolling boil you could probably get the pot stirring itself with surface geometry. Bubbles boil upwards, so putting the right fin shape should get it spinning. Seems like it would require a bunch of machine work so it would probably be prohibitively expensive to make.

Bro has never seen boiling water.

It's called soup.

Convection currents have entered the chat

If you get a good rolling boil, you shouldn't need to stir macaroni.

Tho it is a bit of a waste of energy, since a rolling boil is more than you need to cook pasta.

It shouldn't be difficult at all to add a stirrer that gets spun by the inductive field of an induction stove.

What I'd love to have tough is a pan with built-in temperature sensor, so that I can control the temperature of the pan directly instead of only being able to control the energy output of the stove.

I think there is some chemistry equipment that does that?

Convention currents, but different soups will have different thicknesses and the more heat that's required, but more likely it is the soup on the bottom will burn. Too many variables to design around.

You could make pots that can use a magnetic stirrer like they use in labs, but then you have to fish out a magnet from your soup.

With modern induction cooking this should not be as problematic. You can use the magnetic field to put something in motion

There are things called stovetop fans that look like just a metal base with a fan attached to it, but they have a Peltier module or Stirling engine hidden inside. They use heat from the stove to turn the fan and blow warm air around the room. Should be able to make something using that trick that sticks down into a pot and stirs things. The thickness of the stuff being stirred will be the issue.

Presumably you can use something like a Stirling engine to power a stirrer.

I've thought long about this, specifically those devices that use the pizeo electric effect to move a fan.

Problem is that you need a temperature difference to make the effect go. But ideally I'm imagining a fish that swims around the pot converting heat to work.

Ok here’s my pitch: a pot with a steam powered magnetic stir bar system built into a sealed loop in the bottom.

I could swear I've seen some sort of small three pronged thing that you drop into your pot, and as the liquid boils, it spins and stirs it.

I'm kinda surprised we can't do this by simply insulating the center-most half of the pot's bottom. When heated on a burner, this would make the outsides hotter than the core, which ought to cause our soup to rise along the sides of the pot and then roll back to the center, forming a nice current that auto-stirs.

I suspect the reason we don't do this is that eventually, even insulated, the center would still reach equilibrium & we'd lose our circulation. In order to keep this going, we'd need to change the burners, not the pots. We'd need to design burners to be hot on the outside but cooled at the center.

yes there is , in chemistry they have this weighted object that is put in solution to stir it while its hot.
