Slip Rings are most commonly used. If the power level is low you might be able to magnetically couple the power through the shaft using a pair of concentric coils.

You could always mount a battery and oscillator circuit on the rotating object. That way you could generate your own 60Hz AC.
If you need higher voltage AC, you can transport it onto the rotating object by using a brush contact. A brush contact is made up of two elements: one, on your rotating object, and the other, on your stationary axe (whatever your object is rotating around). The first element is metallic brush. The other element, is a metallic ring. The brush's bristles are constantly in contact with the ring, so electricity can be passed to the rotating object.

Consider feeding a DC thru slip-rings. Install a rotating inverter on your rotating object to convert the DC to AC for your application.

commutators, these are the things used in motors and generators, its hard to give a description without a picture but look it up. Basically if you've ever seen the bit on a BMX which allows the rided to spin the handlebars round without the brake cables getting tangled, it like that but for electronics (thats a poor analogy but i can't think of anything better) then you could attach cables from a mains supply to your object
