Scientists build device to harvest electricity from Earth's spin (www.earth.com)

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.

I guess this is something important to point out when saying something may drastically affect our lives.

Sure, so I mentioned it.

The scale of the effects and their expected outcomes are actually important

Look, I try to keep my comments brief whenever I can. Totally feel free to ask a followup question if you think I left something important out.

No, your responses were great and clear.
