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
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.
concentrated solar heating gets you there using 1/4 of that space and allows for simple energy storage
“simple” storage of burning hot oil mmhm

So now to cook something I need:

it works fine if you need lots of heat offgrid
I mostly need lots of heat when there isn’t much or any sunshine
