DC Power Poised To Bring Savings To Datacenters
snydeq writes "InfoWorld's Logan Harbaugh follows up his '10 IT Power-Saving Myths Debunked' to argue in favor of using DC power in the datacenter. The practice — viewed as a somewhat crackpot means for reducing wasteful conversions in the datacenter just a few short years ago — has gained traction to the point where server vendors such as HP, IBM, and Sun are making DC power supplies available in their server wares. Meanwhile, Panduit and other companies are working to bring down another barrier for DC to the datacenter: a standardized 400-VDC connector and cabling solution. And with GE working to list 600-VDC circuit breakers with the Underwriters Labs, DC's promise of reduced conversion waste could soon be commonly realized."

Who would have thought the GE would be a big supporter of DC.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
I felt a great disturbance in the Force, as if millions of Tesla fanboys suddenly cried out in terror and were suddenly silenced. I fear something terrible has happened.
I thought the power in D.C. caused waste and ineffeciency.
If brevity is the soul of wit, then how does one explain Twitter?

If that's because of DC, does it mean he's fitted with a brushless commutator?

Well, if you put a magnet on him and wound wire around the coffin that could be a clean source of electricity...

The same joke occurred to me, but I felt it was a little to lame to post.
Assuming that you don't modulate the phase variance of the deflector dish, of course.
a standardized 400-VDC connector and cabling solution
I set this kind of system up myself and it works great, assuming you need a lot of cores. I strung together 296 Intel Core 2 Duo chips in series accross the 400VDC supply, so each one gets the specified 1.35 volts. If I want to overclock, I just take a set of alligator clips and shunt across a few dozen of the chips, and it boosts the voltage to the remaining CPUs.
The only problem is that with so many chips, I get occasional failures, just like I do with my old Christmas lights. Then I have to try shunting around each of the CPUs by trial and error until I isolate the burnt out one before I can get my cluster running again. Oh yeah, I also have to be really careful to keep any peripherals I plug in away from each other and/or grounded objects.

Why don't you do it yourself? It's not like there's anything stopping you.
If it's for-profit but free, you're not the customer -- you're the product (e.g., the Slashdot Beta's "audience").
You sir failed to account for the fact that equipment running on 240V operates at TWICE the speed of 120. Therefore you need only half the number of servers, etc.
