      A snippet of the article:

      A trio of US researchers claim to have successfully tested predictions that it’s possible to harvest [clean energy](https://www.sciencealert.com/reservoirs-of-clean-energy-could-be-hiding-inside-our-planets-mountain-ranges) from the natural rhythms and processes of our planet, generating electricity as Earth rotates through its own magnetic field.

      Though the voltage they produced was tiny, the possibility could give rise to a new way to generate electricity from our planet’s dynamics, alongside [tidal](https://www.sciencealert.com/these-ocean-power-stations-pack-a-lot-of-renewables-into-one-floating-platform), solar, wind, and geothermal power production.

      [In 2016](https://journals.aps.org/prapplied/abstract/10.1103/PhysRevApplied.6.014017), Princeton astrophysicist Christopher Chyba and JPL planetary scientist Kevin Hand challenged their own proof that such a feat ought to be impossible. The researchers have now uncovered empirical evidence that their proof-breaking idea may actually work, as long as the shape and properties of the conducting material in their method are set to very specific requirements.

      Tidal is already a way to harvest energy from Earth’s rotation, at least kinda.

    3. in ten years, earth rotational power plants become a reality.

      in 40 years every developed nation starts using them.

      in 80 years a grand plan is formed to power all human electricity using this method!

      in 100 years this goal is achieved….
      but then humans’ energy drain over shoots the available energy, earth stops rotating , and we all fall off the planet after the earth comes to a sudden and unexpected stop.

    4. Disappointing to be on /futurology and hearing everyone say we already have ways to generate power so shouldn’t be trying to find any more. This is cool science – if proven – even if it doesn’t produce meaningful power generation. And cool to have researchers say „it’s impossible“ then come back later and say „well actually….“

      Useful in it’s current state or not, it’s an interesting development.
