"Salt powered" lantern? Now my attitude can fuel something! (I know what it really is, I just wanted to make the joke)

I was going to post that joke. I could probably power that lantern for a good 3 hours.

But it DOESN'T run on saltwater. Saltwater is merely the electrolyte. It runs on the anode, a piece of metal that has to disintegrate in order to provide the energy. Also, this isn't a new invention, it's just a battery.
