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

  1. Jun 6, 2012 #1
    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?

    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. Here are details --> http://science.howstuffworks.com/environmental/green-tech/sustainable/soil-lamp1.htm

    As for Earth's resonant frequency, I'm sure a lot of people know of the Schumann resonances. Links below for proof of existence-->

    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 [Broken]
    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.
