Not to sound dismissive, but I've looked at the photos and being a little bit of a geek that loved crystals and geology as a kid, this spike of aluminum looks exactly what you would get in a mine either with salt or a mixture of salt or other elements deep in the earth. Especially an old salt mine, probably was geologically active. Also, the person in question claims to have found this item in Europe...There are many many mines in the northern regions near Norway and Sweden to which one can procure such oddities. Heck, you can even get such things from a Vancover geode mine. I'm not saying the guy hasn't found something, but I am saying it ain't no ufo part. It was from a battery core it's too large. It would have to be a mesh to allow for a catalyst reaction to happen. Chemical batteries that use aluminum do not use rods, period and end of story, it just wouldn't be efficient to yield the electrons from the aluminum or the battery fluid.
