Scientists at Princeton University and NASA’s Jet Propulsion Laboratory have harnessed Earth’s rotation to generate electricity, proving a concept once thought impossible.
By using a manganese-zinc ferrite cylinder, researchers tapped into Earth’s magnetic field, producing a tiny but continuous electric voltage.
The idea that Earth’s motion through its magnetic field could generate electricity dates back centuries, but past studies dismissed it—until now.
The cylinder was placed in a pitch-black lab at a 90-degree angle to Earth’s rotation, allowing the planet’s motion itself to create a small but measurable electric current.
A recorded 19 microvolts may seem tiny, but researchers say this proves the concept, paving the way for future innovations in green energy.

Despite the excitement, researchers caution that this is just a proof-of-concept, and much more work is needed before practical applications emerge.
