RF Solid-State Cooking (opens in new tab)

This is actually a lot more sophisticated than the comments here are making it out to be. With something like this you can basically get software defined cooking. If you combine it with computer vision and a bit of chemistry, you would get a perfect medium rare steak every time. (You don't need the computer vision part if you can get the RF feedback from the sensors directly) To be fair, there is nothing stopping you from doing this with a traditional magnetron microwave, just that you will need a lot of space for hardware and waveguides to have the same precision and control.

This is just a microwave but built with MOSFETs rather than a vintage 1940's era valve.

They avoid using the word microwave anywhere in the marketing material, which really is telling they're mostly trying to get rid of the 'low quality food' reputation that microwaves have.

I find pretty cool there is a company who is trying to improve a technology that haven't advanced in decades, but a whole simple microwave oven is probably a lot cheaper than the transistors driving those RF signals inside this "cooker".

I don't know how much people would buy this, but I'm pretty sure a lot of restaurants would have one of this if they deliver what they promise.

I'm curious how this system browns the steak (like in their photos), I didn't realise you could achieve that with microwaves alone?

This tech will soon enough get cheaper than classic magnetrons.

Magnetrons require quite large magnets, a vacuum and filament which eventually burns out, and a large transformer with a lot of copper and steel.

The solid state solution is just a bunch of mosfets. Less material means it'll be cheaper eventually when the patents etc. run out.

So does this glorified smart microwave heat the good directly or a plate/stove thing on which you cook the food?

That’s awesome, basically it’s the Metcal of hotplates?
