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 :(

    For a rain enjoyer, you sure like spreading pro sun propaganda

    Just power it using solar panels?

    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.

    You can store the heat in oil, but how do you transfer it into cooking oil? It's not like you can store it directly in cooking oil since it breaks down with heat.

    Yeah it has to be stored in heat-reststant heat transfer oil, that one won't be edible. How to transfer that heat, like in every step before, using heat exchanger, like coiled pipe where that oil flows used as a hotplate or with air blown through it in air fryer
