Just a castaway
An island lost at sea
Another lonely day
With no one here but me
Than any man could bear
Rescue me before I fall into despair
I’ll send an SOS to the world
I’ll send an SOS to the world
I hope that someone gets my
Message in a bottle

With a click to search Google, you eat as much as a lamp for an hour! A query over the Internet does indeed involve a cascade of electrical appliances from your PC to the Google servers, joined by thousands in giant warehouses, data centers, which process data in billions of billions of bytes . “The Internet bubble has generated the production of millions of servers,” explains Adrien Porcheron, CEO Dotgreen, a fledgling firm that helps companies reduce their IT energy bills.
There are approximately 45 million servers worldwide. On their own large data centers have doubled their electricity consumption from 2000 to 2005. Nothing in Western Europe, energy costs of all these “farms” of servers have reached 4.9 billion euros, according to IDC. “The story about the hunger for energy of a Google search is the urban legend,” smiled Adrien Porcheron who nevertheless takes on its site, “because it is very difficult to calculate the energy used by a consumer on equipment shared by thousands of people. ” We know, however, the United States’ data centers consume 3% of the country’s electricity, “noted Steven Chu last month, the U.S. Department of Energy. Within two years, U.S. data centers emit as much CO2 as planes in the United States.
In France, a report prepared by Michel Petit, delivered in September 2009 to Christine Lagarde was concerned “the unsustainable growth model data centers.” In many of them to one kilowatt (kW) spent a server, another kW is needed to dissipate heat. The subject is so concerned that regulators around the world in the coming years could require manufacturers and customers to reduce their power consumption.
Google has more than one million servers
The computer industry has not waited for the recent awareness of policies to make energy a priority. The portfolio has been more influential than environmental concerns. The downside, however: according to a survey conducted by the Green Grid consortium created by the giants Microsoft, IBM, Google, Intel, Sun or AT & T, 72% of companies have no strategy to reduce appetite Electric their data centers.
Google, which has over a million servers worldwide, has worked for ten years to reduce energy costs and even gives advice on how to design data centers more efficient. Our server farms consume “five times less energy than conventional data centers,” assured the end of 2008 Urs Hölzle, Google’s vice president in charge of the operation.
The tracks for green data centers abound. Experts estimate that one third of the electricity consumed by servers is wasted before reaching the machines themselves, especially to convert alternating current into direct current network.
More than the air, “spins servers 24 hours 24 ‘generates a waste, says Anaïs Fourest, society EcoAct, which sells advice on energy efficiency and carbon footprints. “The data centers are designed for spikes, as you never know in advance what will be the demand, full Bad Wurtz, CEO of American Power Assure.
At 3 o’clock in the morning, only a few students look at their bank account but the servers run at full speed. “Servers that lights up according to the request would generate, not the United States, 25 billion dollars in savings . Manufacturers of computer hardware, software and consulting firms have realized the economic importance of green business. For the information technology are not about to stop their race.
Google will sell electricity
On 19 February, Google, one of the largest electricity consumers in the world, received the green light by U.S. authorities to buy and sell on the wholesale market for electricity. Google, which owns the largest fleet of data centers – more than a million servers – have struggled for years to produce its own renewable energy.
In 2007, the firm has created a foundation, Google.org, which funds projects in the fields of solar, geothermal or wind. The search engine has even filed a patent in 2007 to build a tidal barrage. Google claims not to know precisely how to exploit this permission. “We have taken this step to have more flexibility in purchasing power for our own business, including our data centers,” said a spokesman.
NASA RELEASE : 10-080
WASHINGTON — NASA has successfully completed the first science flight of the Global Hawk unpiloted aircraft system over the Pacific Ocean. The flight was the first of five scheduled for this month’s Global Hawk Pacific, or GloPac, mission to study atmospheric science over the Pacific and Arctic oceans.
The Global Hawk is a robotic plane that can fly autonomously to altitudes above 60,000 feet — roughly twice as high as a commercial airliner — and as far as 11,000 nautical miles, which is half the circumference of Earth. Operators pre-program a flight path, then the plane flies itself for as long as 30 hours, staying in contact through satellite and line-of-site communications links to a ground control station at NASA’s Dryden Flight Research Center in California’s Mojave Desert.
“The Global Hawk is a revolutionary aircraft for science because of its enormous range and endurance,” said Paul Newman, co-mission scientist for GloPac and an atmospheric scientist from NASA’s Goddard Space Flight Center in Greenbelt, Md. “No other science platform provides the range and time to sample rapidly evolving atmospheric phenomena. This mission is our first opportunity to demonstrate the unique capabilities of this plane, while gathering atmospheric data in a region that is poorly sampled.”
GloPac researchers plan to directly measure and sample greenhouse gases, ozone-depleting substances, aerosols, and constituents of air quality in the upper troposphere and lower stratosphere. GloPac’s measurements will cover longer time periods and greater geographic distances than any other science aircraft.
During Wednesday’s flight, the plane flew approximately 4,500 nautical miles along a flight path that took it to 150.3 degrees West longitude, and 54.6 degrees North latitude, just south of Alaska’s Kodiak Island. The flight lasted just over 14 hours and flew up to 60,900 feet. The mission is a joint project with the National Oceanic and Atmospheric Administration, or NOAA.
The plane carries 11 instruments to sample the chemical composition of the troposphere and stratosphere. The instruments profile the dynamics and meteorology of both layers and observe the distribution of clouds and aerosol particles. Project scientists expect to take observations from the equator north to the Arctic Circle and west of Hawaii.
Although the plane is designed to fly on its own, pilots can change its course or altitude based on interesting atmospheric phenomena ahead. Researchers have the ability via communications links to control their instruments from the ground.
“The Global Hawk is a fantastic platform because it gives us expanded access to the atmosphere beyond what we have with piloted aircraft,” said David Fahey, co-mission scientist and a research physicist at NOAA’s Earth System Research Laboratory in Boulder, Colo. “We can go to regions we couldn’t reach or go to previously explored regions and study them for extended periods that are impossible with conventional planes.”
The timing of GloPac flights should allow scientists to observe the breakup of the polar vortex. The vortex is a large-scale cyclone in the upper troposphere and lower stratosphere that dominates winter weather patterns around the Arctic and is particularly important for understanding ozone depletion in the Northern Hemisphere.
Scientists also expect to gather high-altitude data between 45,000 and 65,000 feet, where many greenhouse gases and ozone-depleting substances are destroyed. They will measure dust, smoke and pollution that cross the Pacific from Asia and Siberia and affect U.S. air quality.
The Global Hawk will make several flights directly under the path of NASA’s Aura satellite and other “A-train” Earth-observing satellites, “allowing us to calibrate and confirm what we see from space,” Newman added. GloPac is specifically being conducted in conjunction with NASA’s Aura Validation Experiment.
The GloPac mission includes more than 130 researchers and technicians from NASA’s Goddard Space Flight Center, Dryden Flight Research Center, Jet Propulsion Laboratory in Pasadena, Calif., and Ames Research Center in Moffett Field, Calif. Also involved are NOAA’s Earth System Research Laboratory; the University of California, Santa Cruz; Droplet Measurement Technologies of Boulder, Colo.; and the University of Denver.
NASA Dryden and the Northrop Grumman Corp. of Rancho Bernardo, Calif., signed a Space Act Agreement to re-fit and maintain three Global Hawks transferred from the U.S. Air Force for use in high-altitude, long-duration Earth science missions.

NEW ORLEANS–Republicans and tea party activists are fond of accusing President Barack Obama of being a socialist, but today party gadfly Ron Paul said they had it wrong.
“In the technical sense, in the economic definition, he is not a socialist,” the Texas Republican said to a smattering of applause at the Southern Republican Leadership Conference.
“He’s a corporatist,” Paul quickly added, meaning the president takes “care of corporations and corporations take over and run the country.”
Supporters of the Texas lawmaker appear to represent a significant number of the 3,500 attendees here, fueling speculation that Paul is likely to win the straw poll later today. The Campaign for Liberty, Paul’s political outfit, declined to discuss how many of his supporters were at SRLC.
The Texan’s supporters often descend on political gatherings to vote for him in 2012 straw polls. In February, he won the Conservative Political Action Conference’s straw poll with a hefty 31% of the vote.
