rotating outdoor stage

I was at the state fair of texas yesterday to see Kansas, but they had several bands on several different stages.  one of the stages the Kildaires were playing from like 2pm until 7pm with 20 min breaks each hour.  what was interesting to me was that the entire stage was rotating.  their amps and everything was on the rotating stage.  they did have some external mains facing the "audience" area.
 
my question is:  how in the world did they do that???  how do they power the equipment on the stage?  I supposed you could come up with a type of power cord which allows for a rotating stage where the connector is two metal circular plates which touch as it rotates.  I'm just guessing that's how they might do it, tho, I don't know.  does anyone else know?
 
also, how did they transmit the signal to the mains which were stationary outside the rotating stage?  unless it's a wireless transmitter and receiver I can't figure that part out.

yes, of course!  I was thinking more localized, but the bumper car analogy makes more sense.

Forget this rotating stage business.

The important question is, did you have a Fletcher's Corny Dog?

What????!!!!!!!??????

No Becan?

Pffffft

Actually, there was one place that had "chicken fried becan" ('cept they misspelled "becan" ).  but I didn't see it until we were leaving the park and I was not going to be able to eat any more last night.  and I'm sure it would not have been good "reheated" so I didn't get any.

Some people have built rotating houses. Imagine how much more complicated that is, what with the electrics, plumbing etc.

I've thought about fantasy house designs where parts turn.  My solution was to have the stairs and plumbing in the center that doesn't turn, with the top room spinning around it via electro-magnets.

sapcey could build that. He'd use a mouse to start and stop it. Or summat like that.

seriously???  why in the world would anyone want their house to rotate? 
 
 
besides - that thing looks like the Jupiter 2. 

HGTV has a show on the channel on occasion called Extreme Homes...and yeah, they do have houses that turn.... not completely in a circle but such that it tracks the sun on a daily basis and returns to the starting point during the night.  All electrical, plumbing, and other utilities are on flexible connections and hoses to make it all happen. 

And what is wrong with a house looking like the Jupiter 2?  That was one cool ship.

LOL!
 
It worked! My grand daughter just about fell out of her chair laughing. 
 
Turning the house is not a problem.....I'm kinda hung up on the floating part.
 
Got the plumbing issues solved-kinda- just started thinking about after the post above..
Easy but the house has to stop turning at specific location(s) to use facilities.
Probably a good safety feature while showering anyway.

Well, with my approach, the facilities are in the middle area that doesn't turn so no issue there.   As for why, I can think of several reasons with the biggest two being able to turn away from the sun during summer and towards the sun during winter.
