If I hook up a big gear to a much smaller one to spin it incredibly fast could that be used to generate power? And if so could that idea be used to generate power on a much bigger scale? In my brain it makes perfect sense but there must be something wrong with this idea.

If you feed 10J of electric energy into a 90% efficient electric motor to generate 9J of mechanical work and then convert those 9J of mechanical work into electrical energy via a 90%efficient generator you end up with 8.1J of electric energy. If you repeat that often enough you’ll end up with 0J of electric energy. Congratulations, you invented a machine that turns electric energy into heat! Gear ratios don’t change anything about it.
