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. Here are details --> http://science.howstuffworks.com/environmental/green-tech/sustainable/soil-lamp1.htm more links: http://www.architecture.uwaterloo.c...i/competitions/2010/wong/wongA_ARCH684_04.pdf https://www.soils.org/publications/sssaj/abstracts/43/4/SS0430040808 As for Earth's resonant frequency, I'm sure a lot of people know of the Schumann resonances.

Or is it something worth testing? If so How would you come about it?
