Fluid as a medium to transfer electricity

Click For Summary

Discussion Overview

The discussion revolves around the use of fluid as a medium to transfer electricity, specifically in the context of a device referred to as a "Hydro Clock." Participants explore the mechanisms by which the fluid may facilitate electrical conduction and the nature of the underlying principles, comparing it to other simple battery systems.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant suggests that the fluid acts merely as a medium to transfer electricity from an internal battery.
  • Another proposes that the mechanism is similar to a lemon clock, where an electrolyte generates current when liquid is added.
  • A later post clarifies that the fluid serves as an electrolyte that transfers charge between electrodes, akin to a galvanic cell.
  • One participant challenges the explanation provided by another source, asserting that the internal converter extracts electrons from liquid molecules to generate power, emphasizing that electrons are taken from the anode rather than the water itself.

Areas of Agreement / Disagreement

Participants express differing views on the exact mechanism by which the fluid facilitates electricity transfer, leading to an unresolved discussion with multiple competing interpretations of how the system operates.

Contextual Notes

There are limitations in the discussion regarding the assumptions made about the nature of the electrolyte and the specifics of the electrical generation process, which remain unclear and not fully explored.

I think it just uses the fluid as a medium to transfer electricity from an internal battery, my friends aren't so sure. Any thoughts on this out there?

I am thinking it is something like a ‘lemon’ clock, except instead of a lemon one just provides some other electrolyte. There could be the makings of a battery exposed to the electrolyte tank which, when liquid is added, generates the current to run the clock.

You are right. More accurately, the fluid serves as an electrolyte which transfers charge between two electrodes that make up the battery for the clock. The principle is the same as that of any regular galvanic cell.
 
They have these on thinkgeek as well.

Only their explanation is wrong!

The internal converter simply extracts electrons from water (or other liquid) molecules and provides a steady stream of electrical current acting as a fuel cell to generate power to the clock.
Electrons are "extracted" from the anode, not from water.
 


Put it right next to the bubbling sea chest in the aquarium.
