The possibilities of infinite energy?

+0
−0

So the idea is that the world has been destroyed, and an emergency plan to put the rest of humanity on floating cities/islands has been put in place. These islands subsist off of some sort of generator that has been in place since the beginning of this plan. The question that I have is what sort of generator would be needed to keep these cities afloat, but can be scaled down so that it would fit some sort of weapon, such as a laser or plasma gun or rail gun.

Ignoring the physical/material constraints of aforesaid weapons and generator, is it possible to create an infinite energy generator that can instantly output large amounts of energy with low to no human contact? I think that I am aiming for high voltage, only. Current doesn't matter as much.

An idea that I did have was to create a chamber containing a micro black hole, and have that micro black hole detonate, then harness the energy with near perfect efficiency, creating another micro black hole. The excess energy, should there be any, would be stored in battery cells with infinite capacity for charge. But I don't think that this would work, considering the mass required for even a micro blackhole.
