This new device is designed to generate electricity from the Earth’s rotation

In a world chasing cleaner energy, a group of physicists may have uncovered a surprising new way to make power: by tapping into the Earth’s own rotation. That’s right, researchers at Princeton University have finally shown that passive electricity generation might be more than just theory.

This new experiment, recently highlighted in Physical Review Research, demonstrates that a specially designed device can produce a continuous, measurable voltage—powered entirely by the planet’s spin through its magnetic field.
