RE: Why do we pay so much to live? - Living Free
So let your imagination go to a bigger cup, with twice as much salt water and twice as much metals, youd surely get 1v?
There is a theoretical upper bound for how big voltage you'll get, it's all defined by the metals being used.
To increase the voltage further you will need several such batteries, connected in series - like shown on the potato battery picture.
Came to think, that's actually the reason why we call it "battery" at all - typically one would need lots of cells - a "battery" of cells - to do anything useful.
