For nearly two centuries, scientists have wondered if Earth’s rotation through its magnetic field could produce electricity.

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 ...

Experiments suggest an unusual magnetic material could help harness energy from Earth’s rotation. But not everyone is ...

"The idea is somewhat counter-intuitive and has been argued since Faraday," University of Wisconsin ... amount the Moon's pull slows the Earth's rotation over the same period.
