If you do not know what the Baghdad battery is,
here is a good website where you can find information about it.
Anyway, what do yall think it was for if not for electricity? The most credible argument I have heard against it being used for electricity was a shaky argument that it was used for some ritual that we don't know what it was used for. Seriously. That was the only argument I heard against it: well it could have been used in a ritual, but we have no idea what ritual that was. I mean, just the fact that the battery actually works is huge. People back then may not have known why it worked, but so what? I don't know how gravity works, but I know that it does (and that it is a bitch). Anyone have any ideas what the Baghdad battery could have been used for if not for electricity?
Also, we know that ancient peoples knew of the static electric characteristics of amber, but we don't really know what they may have thought about it or if they used it for anything. Well, I don't know if they used it for anything. Anyone have any more information about amber and what it may have been used for?
One more thing now... Anyone know anything about Hero's engine? Was it just a curiosity or did it have a practical use?
