    @Moon batteries are just surprisingly easy to make, it's no surprise that some storage pots might accidentally be batteries
    i mean, anyway, what use would an ancient civilization have for a low-voltage galvanic cell

        Yakhchāl
        A yakhchāl (Persian: یخچال "ice pit"; yakh meaning "ice" and chāl meaning "pit") is an ancient type of ice house, which also made ice. They are primarily found in the Dasht-e Lut and Dasht-e-Kavir deserts, whose climates range from cold (BWk) to hot (BWh) desert regions. In present-day Iran, Afghanistan, and Tajikistan, the term yakhchāl is also used to refer to modern refrigerators.The structure typically had a domed shape above ground, a subterranean storage space, shade walls, and ice pools. It was often used to store ice, but sometimes was used to store food as well as produce ice. The subterranean space and thick heat-resistant construction material insulated the storage space year-round. These structures were mainly built and used since ancient times in Persia. History Records indicate that these structures were built as far back as 400 BCE, and many that were built hundreds of years ago remain standing, where Persian engineers built yakhchāls in the desert to store ice, usually made nearby. The ice created nearby and stored in yakhchāls is used throughout the year...
