An Earth battery is a pair of electrodes made of two dissimilar metals, such as iron and copper, which are buried in the soil or immersed in the sea. Earth batteries act as water activated batteries and if the plates are sufficiently far apart, they can tap telluric currents. Earth batteries are sometimes referred to as Telluric power sources and Telluric generators.

Famous quotes containing the word earth:
“No imperfection in budded mountain,
Valleys breathe, heaven and earth move together,
daisies push inches of yellow air, vegetables tremble,
green atoms shimmer in grassy mandalas,
sheep speckle the mountainside, revolving their jaws with empty eyes,
horses dance in the warm rain,”
—Allen Ginsberg (b. 1926)
