Ask HN: Practicality of harnessing geomagnetic fields for electrical generation?

Years ago I would have asked this on the 'Overflows. Alas, those innocent days are long gone. I could always ask AI, but how can you know?

The Earth produces a moving magnetic field (small teslas, but large extent yes?). Moving magnetic fields produce electrical current, right? Could you add "geomagnetic power" to other clean/renewable sources with the right technical solution, or is it fundamentally impossible?
