Is it possible to harness electricity from the ground of the earth?

AI Thread Summary
Harnessing electricity from the Earth's ground may be possible through methods like an antenna circuit tuned to 7.8 Hz, the Earth's resonant frequency, or using an Earth battery, which generates voltage through different electrodes placed in the ground. Historical experiments, such as those by Alexander Bain, have shown that Earth batteries can produce around 1 volt. The Schumann resonances provide scientific backing for the concept of Earth's frequencies. However, skepticism exists regarding the practicality and efficiency of these methods, with suggestions to explore more reliable energy sources like wind and solar power. Overall, while the idea is intriguing, its feasibility for significant energy production remains questionable.

By means of an antenna circuit tuned to 7.8hz (earth's resonant frequency). Orrrr an Earth battery? I'm not quite sure how those work exactly but can they be tuned?

Edit:
Earth battery (or Earth Return) was something discovered by Alexander Bain, he got about 1 volt from the ground by placing 2 different electrodes into the ground connected to each other from a wire.

Okay I would appreciate a non-biased answer of how/why it may or may not work. Or is it something worth testing? If so How would you come about it?

Please be very careful not to post pseudo-science here on the PF. That is against the rules here. Please provide credible scientific sources for each of the items you have mentioned (the Earth's resonant frequence -- resonance of what?, and what an Earth Battery is). The sources need to be from mainstream science sources, not wikipedia and news articles, etc.
 
You could look at http://en.wikipedia.org/wiki/Telluric_current
This also looks interesting
http://www.earthinginstitute.net/commentaries/gaetan_electrical_surface.pdf
But I don't know how credible that source is.
Anyway I don't think you can get much power that way. I would look into wind and solar instead.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
