DC Power Saves 15% Energy and Cost @ Data Center
Krishna Dagli writes "Engineers at the Lawrence Berkeley National Laboratory and about 20 technology vendors this month will wrap up a demonstration that they said shows DC power distribution in the data center can save up to 15 percent or more on energy consumption and cost. The proof-of-concept program, set up at Sun Microsystems' Newark, Calif., facility, offered a side-by-side comparison of a traditional AC power system and a 380-volt DC distribution system, running on both Intel-based servers and Sun systems."
Read Stephen King's "Tommyknockers". You can do a lot of things if you go DC-only!
Where were you when the voynix came?
But we wouldn't know...As soon as one dies he gets shredded and a replacement takes his place. Thousands of IT workers die everyday and most people don't even know it.

At 60 revolutions per second.
220VAC can be fatal if you manage to ground yourself in a fashion that causes the current to pass through your chest, but it's uncommon and good practice working with live circuits means you try to avoid the situation. In particular, people working on the innards of CRT tubes are advised to keep one hand in their pocket when near the flyback transformer and HVAC power circuitry driving the vacuum tube to avoid a short from one hand -> chest -> other hand.
Getting one hand shocked at 220VAC is not pleasant, but it's not especially painful either...

Quiet you, and back to the data mines!
Information wants a fueled airplane waiting at the hangar and no one gets hurt.
I always thought the opposite was true. Here is a wiki quote that also supports that:
Just make sure that the article that you are quoting wasn't edited by Stephen Colbert...
"And since this is in the datacenter, you can train your people not to pee on the red wire"
We have dedicated and colocated server in various datacenters, so I have a fair amount of experience with them, and so I need to ask you... PLEASE give me an example! An example of a datacenter staffed with people who can be trained not to pee on a red wire, because if they can be trained to do that... hell they might even be able to reboot the right machine from time to time!
The revolution will not be televised... but it will have a page on Wikipedia
