I'd like to know how it generates electricity for that long with just one filling of plain water

[@Nexit1337]

just a simple question
how does it generate enough power to last for 3 months? in one filling?
because "magic magic magic" is not really a thing
and the fact that it never shows the back of this clock in the video makes me think that there is a battery inside to do everything

[@sadootaqoo981]

nexit 1337 i feel the same, and it seem like they designed it such a way that water is the final element to complete the circuit!
