from "Just Another DIY Fan" contains these words:

Is it not possible that the water itself is acting as a
weak electrolyte and that is where the REAL voltage
being read is coming from? I.e .it's nothing to do
with the mains.

If you can find an electrochemical pair that can make 35 volts with a
single cell you're going to be rich beyond the dreams of avarice!

Possibly, but more likely from pyrotechnics than battery manufacture.
The higher the cell voltage, the faster things fry up. Cells of 4v or
so are usually over in seconds, so 35v would be a firework or bomb.

And an ac cell would certainly interest everyone
