How are LED car rims powered?


Anyone know how power is supplied to spinning car rims?

Great! Thanks! Those were the rims I had found, but I did not find the tech info.

So the device used to make an electrical connection through a rotating assembly is called a "slip ring".
My other guess would have been some induction coupled device like those new mat chargers for cellphones.
...not that I have them on the minivan. $20K for a set.
