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.

none of it would matter for hundreds of thousands of generations of humans.

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

Hydroelectric has actually had measurable effects

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

Sure, so I mentioned it.

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.
