If a system gets a bump in energy output vs the energy put into it you end up with a perpetual motion machine. The law of conservation of energy stops that. Add on top of that friction and vibrational losses before converting the kinetic energy to electricity you will end up causing more drag than the amount of energy generated can offset.
