I was surveying a data centre recently and found this.
Spinning CD/DVD's on top of large storage arrays (hard disk drives).
Not only was it cool that a tech / engineer discovered they could do this but I loved the duality of one storage media spinning on top of another.
@Keltic: Perpetual Motion!!!! now all we need to do is harness it.... wait....
Cool video though, do they just keep going forever?
If you only knew a) how much power they consume and b) how much power is used to drive the cooling :-)
There were spinning when I arrive and spinning when I left. I was on site 4 hours. The room is usually a lights out site and as you can tell from the CRT's, it's early 2000's equipment so they could have been spinning for years!
@Keltic: WAIT... They were spinning when you arrived and still spinning when you left? Dammit! We are still in the dream!
