Ok, I am new to this forum and have a few questions.
To my understanding (please correct me if I am wrong), a generator works by combustion pushing a piston, which spins a rod, attached to a wheel with magnets on it in a coil of wire.
If one was to somehow put a gear between the spindle and the wheel with the magnets on it so that it could spin faster with still using the same amount of force as normal, would you be able to generate more power?
No. To turn the input spindle at the same speed would require twice the torque if the gear ratio were 1 : 2.
But yes, the power output of the generator would be double.
There ain't no such thing as a free lunch.

Yes, The faster you make the generator turns, flux lines will cross faster and the voltage will be produced more. And revolutions per minute isn't an only factor. Voltage and RPM are directly proportional assuming the two interacting magnetic fields stay approx the same.
Yeah, but read Leadfoot's answer.
