American researchers have measured a tiny electrical voltage by exploiting Earth's magnetic field in the planet's rotational motion. This discovery, though modest, revives a scientific debate nearly ...
Electricity can be generated from the energy of Earth rotating through its own magnetic field—according to a provocative claim put forward by physicists this week. The findings are controversial but ...
The blobs lie at the base of Earth’s mantle, around 1,802 miles beneath Africa and the Pacific.
