so we can't do this ourselves. like we don't know what it is exactly so we can reproduce technology for hundreds of years ago? that doesn't make sense to me kind of, like how do we not know how it works, that seems ridiculous,(reply>), We know exactly how it works, we just don't know exactly how they built this specific example. It's like finding a sealed sarcophagus: You know what's in it, but you don't know any details.  <br><br>This battery delivers power on the order of single microwatts while charging your phone takes about 5W. That means you'd literally need millions of these to provide enough current to charge your phone. Or to put it another way: This battery has in its 170+ years has delivered about the same amount of energy as a cell phone battery can contain (3000mAh).<br><br>It's special in the sense that it is stable for so long, but the energy capacity, voltage or current aren't very special. Impressive for the time, but pretty much completely useless.
