"the bitumen completely covers the copper cylinder, electrically insulating it, so no current can be drawn without modifying the design;"

"The artifacts strongly resemble another type of object with a known purpose—namely, storage vessels for sacred scrolls from nearby Seleucia on the Tigris. Those vessels do not have the outermost clay jar, but are otherwise almost identical. Since it is claimed these vessels were exposed to the elements, it would not be at all surprising if any papyrus or parchment inside had completely rotted away, perhaps leaving a trace of slightly acidic organic residue."
