Can a Motor-Powered Generator Increase Electrical Output?

[Khumo]

Hello everyone,

I would like to know if it is possible to produce more electrical power from a generator if it is powered by an electric motor through a speed multiplier gearbox? Any answer will be greatly appreciated.

More power than what?

Short answer: no. That would violate conservation of energy. The gear box losses alone would prevent that from working.
