Power generator powered exclusively by gravity is possible?

No. Newtonian gravity is a conservative vector field (or conservative force) which mean that energy that you extract from the field has to be put in first. This is technically stated as the work done around any closed looped is equal to zero. For example, you raise your pet cat up 1 meter (you do work against gravity) you let go and gravity does the same amount of work on your cat. Any work done by a mechanical machine must obey the same principle.
In summary, no, a generator cannot be powered by gravity because you simply cannot extract net work from the field.
However, hydroelectricity is an example of using gravity to do work, but in this instance to water was already at the higher potential.
