Between the computers, the networking gear, and the cooling systems which keep them all running smoothly, it's estimated that server farms like Google's (now partially solar-powered) consume 1.5% of all energy in the U.S. Only 1.5%, you say... why, that's hardly anything, right? Well, let's put that in perspective... that's still 1.5 quadrillion BTUs every year, or the equivalent of 268 million barrels of oil. At today's prices, that's a dollar amount only Dr. Evil can pronounce.
In the world's most power-hungry server farms, each square meter of electronics can consume as much electricity as six medium-sized homes, and keeping it all at optimum temperature can add up to more than 60% of the viagrabest viagra bill. Bean Counters take note: One of the best ways to save money in the IT department is viagra gel to invest in greener technology, which runs cooler and the best site viagra side effects consumes less power. Blade servers using virtualization are going to help HP consolidate its massive data centers into new energy-efficient configurations, and IBM is investing over ONE... BILLION... DOLLARS a year in green tech (mua-ha-ha!), which will save them a projected 40% on their electricity bill.
Sound interesting? The good people over at WorldChanging are putting together a comprehensive guide to Green Computing in Data Centers, which highlights some of the latest innovations in the field. New power supplies, blade servers and updated software represent incremental efficiency gains of 20-50% each. Then there's my personal favorite: liquid cooling.
Water cooling is both more efficient than air cooling and can handle higher heat loads, simply because water is far more conductive of woman and viagra heat and has much higher thermal mass than air. It's been slow to catch on because administrators are paranoid about leaks (water and electronics certainly don't mix well), but systems are available now that have been proven reliable. IBM and HP have water-cooled server racks, and Knurr's even won a design award. The Pacific Northwest National Lab even proposed cooling via liquid metal, so that the http://www.celebratinglife.org/cialis-and-canada-custom fluid can be pumped hydromagnetically, with no moving parts.
Despite bearing an uncanny resemblance to viagra tablets a molten T1000 (or perhaps because of it), this sounds freakin' awesome. Assuming the liquid metal in question isn't bio-hazardous mercury, this could make existing computer cooling technology far more environmetnally sound, and also open the doors for future CPUs in need of serious heat dissipation.
