Europeans use 220V for everything.

So in Europe the phenomenon of a stove heating faster than a kettle would not be observed. Isn't that what I said?

230V/3kW induction stove boils a cup of water faster than you can get the cup from the cupboard.

I guess you could have a hot spot on the pan if the coils are ill-designed or you’re putting a large pan on a small burner? The pan will only heat up near the coil, so if the coil covers only the center third of the pan, only that will heat up (though some pans have a heat-spreading layer to mitigate this, and sometimes to add some more inertia depending on the pan’s purpose).

> I guess you could have a hot spot on the pan if the coils are ill-designed or you’re putting a large pan on a small burner? Yes, but then it’s hardly a problem with the technology if you put a large pan on a small burner. As for the rest, in all cookers I have seen, the coils cover the whole surface, except for a small spot in the centre. Besides, induced current does not happen only where the cookware is closest t…

With most cookware it's pretty obvious where the coils are when trying to simmer. With thinner stuff like carbon steel the hot spots can be pretty nasty: https://www.youtube.com/watch?v=pifD__DIxGU

It's the ideal cooker for me. I take shower only once per week and most of my gas cost went to cooking. It will save ~75% of by gas meter reading (but only ~15% on my gas bill though).

>Though induction stovetops can be faster yet, and just as clean. You have the mother of all hotspots on the pan (less relevant for boiling) where the induction ring itself is and getting simmer right is harder. Induction as implemented right now is on/off with full blast for the duration and just increased downtime. It is not the same as low constant output.

> You have the mother of all hotspots on the pan (less relevant for boiling) where the induction ring itself is and getting simmer right is harder. Not at all. There is no significant hot spot as heat is actually produced by the bottom of the pan and not the coils themselves. > Induction as implemented right now is on/off with full blast for the duration and just increased downtime.

> All the devices I have used were perfectly fine generating a low, constant heat

I have never seen an induction cooktop that could generate low, constant heat. Even pretty pricy ones (eg. a 3000€ Bora hob with integrated extraction) showed a clear on/off cycle at the lowest heat settings. But maybe tech has improved in recent years, and there are hobs now that have constant low power output?

Maybe the effect also just depends on your cookware? On pots with a heavy bottom with aluminium or copper core you probably won't see the coil patterns and the on/off effect will be less pronounced. If you have a pot with a thin stainless steel bottom, you will definitely see uneven heat, the power from an induction coil is not completely homogenous.

The gas end-to-end "efficiency" will not improve drastically ever, while for an electrical stove it is tied to energy production. Arguing with end-to-end efficiencies and power plants is misleading, as I can power my induction stove from my solar panels

That's true, but I power mine from the municipal grid that burns stuff to make steam and then electricity

Might still be better as efficiency goes up with temperature and industrial generators can achieve much higher temperatures that what you can at home, and also include some clean sources of energy into the mix.

My microwave has a picture of a cup with a spoon in it, this stops superheating.

How?

It provides a non-smooth surface to induce steam bubbles to form.

I know in chem labs we used to use little chunks of ceramic for test tubes, but those aren't desirable in your tea.

I always wanted some kind of "collar" that I could put around a burner to try to direct that excess heat back into the pan/pot.

The problem is you need airflow or you generate carbon monoxide instead of carbon dioxide. So simple solutions can get more heat but also kill you.

Scroll down a bit and you get white text on a bright yellow background.

I'm a European who finds kettles stupid. I own one because someone didn't appreciate my house's lack of kettle and got one despite my protestations. I own (1) a induction stovetop, (2) a microwave… both will perfectly boil water just as fast. Why do I want to waste counter space on a kettle. My kitchen is tiny. I have the same complaint about a ricecooker. It's perfectly easy to cook rice in a pot. Sure it's convenie…

I've never owned a rice cooker but I'm led to believe the rice they make is superior to anything you can reasonably achieve in a simple pot.

It's far easier to achieve consistent results, for sure. We have a small one and it's the best rice we can make at home without significant effort.

And how much CO2 is going to be produced manufacturing and shipping the device they're selling you? Not to mention the batteries it needs.

I was thinking the same, probably much more than the CO2 saved with the whole passive cooking thing...

Not to mention some fine marketing bs like how it runs on 2 "environmentally friendly AAA batteries"!
