Scientists Build Device to Generate Electricity Using the Earth's Rotation

A team of physicists investigated the possibility of generating electricity from the Earth's rotational energy, presenting their findings in Physical Review Research. Led by Christopher Chyba from Princeton University, the team created a device consisting of a manganese-zinc ferrite conductor and electrodes, aligned at a 57-degree angle to the rotational motion and magnetic field. They reported a voltage output of 17 microvolts, although this is minimal and challenged by experts who express skepticism about the results and methodology, suggesting the concept may not be feasible as a renewable energy source.

"The idea is somewhat counter-intuitive and has been argued since Faraday," University of Wisconsin-Eau Claire emeritus physicist Paul Thomas, who wasn't involved in the research, told Nature.

Retired physicist Rinke Wijngaarden, who found the effect didn't work in his own 2018 experiments added that he's "still convinced that the theory of Chyba et al. cannot be correct."
