A Princeton-led team has built a tabletop device that generates voltage directly from Earth’s rotation through its magnetic field. While the power output is orders of magnitude too small for practical electronics, the breakthrough suggests Earth’s spin could someday provide constant, fuel-free energy if the effect scales up. The team is now calling for independent labs to reproduce the results.
Oh great, I’m sure absolutely nothing can go wrong if you scale this up to meet humanity’s growing demand for electricity.
It’s free energy!
There is already tidal power generation slowing down the Earth’s rotation, though not by much.
Oh this will be fun! But I wouldn’t worry we going run out of drinkable water by 2040, so we don’t need to worry about this.
