    They’re literally small convection ovens rebranded. They’re not magic.

    Look up how microwaves work. Those are way, way fucking cooler. The way they generate the microwaves is cool as hell.

      Things don’t need to be revolutionary to be life changing. Could I have used the convection oven for this one slice of pizza? Sure. Would I ever? Hell no.

      But yeah, microwaves really are neat. We’re going to fling these electrons around in these very specific magnetic fields and out pops light you can’t see.

      They’re closer to impingement ovens than convection ovens.

      Convection ovens (or “fan forced ovens” in some countries) use a fan to gently and evenly circulate the hot air, whereas impingement ovens and air fryers use higher velocity fans to blow the heat directly onto the food.

            Just saying it’s not new or miraculous technology 🤷🏼 it’s just a clever and convenient consumer product.

            The better we can differentiate consumer trends and marketing from actual technological innovation, the better off we’ll be. cough AI cough

      you know what would be a lot cooler? same thing not needing electricity (concentrated solar can get hot enough and heat can be stored in hot oil)

        But it wasn’t sunny today and I wanted fries and don’t have space to store hot oil :(

          concentrated solar heating gets you there using 1/4 of that space and allows for simple energy storage

              yeah you put it in a barrel, pump hotter oil through coiled pipe, hot (storage) oil floats to top, when you draw heat through another coiled pipe cold oil falls to bottom. just put mineral wool around it. much cheaper than batteries

              solar water heaters work the same way except they use water

                So now to cook something I need:

                • A solar collector
                • Hot oil storage
                • Heat exchanger (unless I’m deep frying I guess)
                • Hot oil piping between collector, storage and cooking appliance

                I’ll take the solar panels which I already have wiring for, are useful when there’s a surplus (because I can sell the electricity) and which also power my computer. Not that I have panels at the moment.
