With normal cooking, your pot or pan sits on a source of heat (gas, electric coil, etc) and then gets hot itself and heats the food inside it. This is known as thermal conduction: heat is transferred from the source to the pot touching it. Induction cooking, on the other hand, uses a — get ready for this — electromagnet to heat the pot up without ever touching it. Seriously. Electromagnetic induction is actually used in all kinds of other things: generators, transformers, motors, and wireless chargers, to name a few.
The best thing, aside from it being wireless? The cooking surface stays cool! It will heat up a little from the hot pot sitting on it, but the whole idea is that an electromagnet zaps your pot, and only your pot, to whatever temperature you want. It is literally the coolest stovetop ever. You can put a book on the stove and put the pot on the book, and the pot will heat up, but the book won’t.
But wait, there’s more! It’s also faster, more precise, and more energy efficient than normal cooking. Ah-mazing. Pick your jaw up. Here’s a video of it in action:
Crazy futuristic technology, right? Nope: it was invented a hundred years ago. One hundred. Companies like Westinghouse and Sears sold these in the 1970s and ’80s, but somecrazyhow, they never took off. Maybe humanity can only handle one awesome new cooking thing at a time, and the microwave won.
In any case, these are available for sale right now, at this moment. You can find them on Amazon starting at like 60$ for the small, portable ones. It boggles the mind. The one catch — you knew there’d be one — is that you have to use cast iron pots, or other cookware that responds to magnets. But that’s ok, because cast iron is in right now anyway. Right now, in the future that snuck up on us with augmented reality and wireless cooking.
