Came across this article about an MIT experiment that led to the discovery of a “new” way for storing energy. This method uses materials that would have been accessable, or would compare to things that would have been accessable to some ancient civilizations.
This reminded me of archeological findings of clay cylinders that some believed could’ve been used like an ancient battery. I’m only going by memory here so forgive me if the ancient battery theory has been fully explained or debunked. It’s been a long time since I’ve caught an Ancient Aliens episode.
