I was shocked about “electric rocks” but it seems to be just a fancy word for “metallic minerals”.
The article also says
Geiger determined that natural mineral deposits on the ocean floor, called polymetallic nodules, contained elements including cobalt, nickel, copper, lithium, and manganese—all of which are critical components of batteries.
I think I have seen some video about an Australian entrepreneur who wanted to “harvest” those things off the seafloor, to great concern of environmentalists.
I guess it was unexpected that rocks can create a functional battery, and not have been drained after all this time.
How cool is that the guy’s surname is Geiger? I mean, it’s not radioactive but… well I think it’s cool.
“Geiger” is the colloquial German word for somebody who plays the fiddle.
Usually folks use “shocked” when something at least slightly negative happened.
Break water in pieces, with these electric rocks.
