In Iron Man 2, there is a second when Tony Stark is observing a a long time-old movie of his deceased father, who tells him “i am confined by using the technology of my time, however sooner or later you will figure this out. And if you happen to do, you'll trade the realm.” It’s a piece of fiction but the concept expressed is legit. The visions and ideas of technologists are often smartly forward of the know-how of their times. megastar Trek may also have at all times had it, nevertheless it took the relaxation of us many years to get capsules and e-readers right.
The idea of liquid cooling sits squarely in this class as well. while the concept has been round seeing that the Nineteen Sixties, it remained a fringe conception when in comparison to the an awful lot more cost-effective and safer air cooling method. It took one more forty unusual years earlier than liquid cooling even began to take off in the 2000s, and then it changed into ordinarily constrained to laptop hobbyists who wanted to overclock their CPUs well past the advised limits set by means of Intel and AMD.
these days, despite the fact, liquid cooling seems to be having a second. which you can purchase a liquid cooling system to your computer for below $one hundred, and an entire cottage trade of business and statistics middle carriers (like CoolIT, Asetek, eco-friendly Revolution Computing, Ebullient, just to identify 4) are all promotion liquid cooling of statistics center device. Liquid cooling remains essentially used in areas of supercomputing, excessive efficiency computing (HPC), or other situations involving huge amounts of compute vigour the place CPUs run at nearly 100% utilization, however such a use case is fitting mainstream.
There are two average sorts of liquid cooling: direct to chip and immersion. In direct to chip, a heat sink is attached to the CPU similar to with a common fan, however in its place of a fan there are two tubes related. It has one tube the place bloodless water comes in and cools the warmth sink, which is absorbing heat from the CPU, and one pipe to take the sizzling water away. it is then cooled and again to the CPU in a closed loop no longer not like the human blood flow.
With immersion, the hardware is flooded with a liquid tub, which have to undoubtedly be non-conductive. often, this strategy can premier be compared to the pools used to chill nuclear reactor rods. Immersion is a great deal more innovative and requires an awful lot extra high priced coolant than direct to chip, that may still use simple-old water. On accurate of that, there is the risk of spillage with immersion. For that rationale, direct to chip is a lot greater universal for now.
For one foremost example, take Alphabet. When Google’s mum or dad enterprise Alphabet brought its TensorFlow three.0 AI processors in can also 2018, CEO Sundar Pichai mentioned the chips are so powerful, “that for the primary time we’ve had to introduce liquid cooling in our information centers.” The change became the fee Alphabet paid for an eight-fold development in performance.
On the flip aspect, Skybox Datacenters currently introduced a large, forty,000 server supercomputer for oil and gas exploration from DownUnder GeoSolutions (DUG). This initiative is expected to deliver 250 petaflops of computing power, greater than any present supercomputer—and the expected liquid cooling system would enclose the servers, the usage of more than 720 enclosures in absolutely submerged tanks filled with dielectric fluid.
either manner, “Liquid cooling is the cooling of the long run and always can be,” referred to Craig Pennington, vice president of design engineering at facts middle operator Equinix. “It looks so glaring that’s the correct component to do but no one has performed it.”
So how has liquid cooling gone from esoteric science on the fringe of computing to near-mainstream in contemporary information centers? like all technologies, it became partially the result of evolution involving trial and blunder and loads of engineering. however in particular for liquid cooling, these days’s huge information core operators should still perhaps thank the early overclockers, who can also truly be the unsung heroes of liquid cooling.The IBM gadget 360 facts processing control panel. #VintageChic H. Armstrong Roberts/ClassicStock/Getty photos What we focus on after we discuss liquid cooling
Liquid cooling in reality entered the generic creativeness returned in 1964 when IBM explored immersion cooling for the company’s equipment 360 mainframe. (The system 360 become one of the business's first mainframe computers; while IBM had seven hundred and 7000 sequence mainframes for greater than a decade, the system/360 "ushered in an era of computing device compatibility—for the first time, allowing machines across a product line to work with each other," in accordance with IBM.) The idea was standard: chilled water would be run through a contraption that cooled the water right down to under room temperature, after which the water could be supplied without delay to the equipment. IBM’s most advantageous setup used what’s now known as rear door cooling, where a radiator-like equipment turned into installed on the lower back of a mainframe. This equipment drew in sizzling air from the mainframe by means of fans, and that air became then cooled with the aid of the water, an awful lot like how a radiator cools a vehicle engine.extra studying 50 years in the past, IBM created mainframe that helped send men to the Moon
Over the time due to the fact that, engineers enhanced upon this primary theory, and two dominant types of liquid cooling eventually emerged—immersion and direct contact. Immersion is exactly what it says: the electronics are sitting in a liquid bath that, for obtrusive factors, can not be water. The liquid have to be non-conductive, or dielectric (organizations like 3M even engineer fluid especially for this goal).
Immersion, though, has lots of challenges and downsides. because it sits in liquid, the server can simplest be accessed from the desirable. That’s where exterior ports ought to be observed. A 1U (rack unit) solution is impractical, so you can’t stack the racks. The dielectric fluid, continually mineral oil, is terribly expensive and might be messy to clear up if it spills. You want particular complicated drives and will probably have to spend a whole lot to retrofit an information core. That’s why in the case of the Houston supercomputer outlined above, immersion is premiere performed with a new records middle rather than retrofitting an old one.
by contrast, direct contact liquid cooling is the place a warmth sink (or heat exchanger) sits on the chip, identical to a daily heat sink. as a substitute of an attached fan blowing on the warmth sink, although, this setup has two water pipe connections—one to carry cool water in to cool the plate, and one more to remove the scorching water created with the aid of contact with the heat plate. This has develop into essentially the most average kind of liquid cooling, adopted via principal OEMs like HP enterprise, Dell EMC, and IBM, in addition to cupboard and enclosure makers like Chatsworth techniques and Schneider electric powered.
Direct to chip makes use of water, though it’s somewhat specific concerning the pleasant of water. You definitely can’t use unfiltered municipal water. just examine your faucet or shower head. Who wants a calcium buildup in their servers? at the very least, direct contact liquid cooling requires pure, distilled water, and sometimes water blended with an antifreeze. This classification of liquid coolant is a really exact science in and of itself.magnify / Hmmm, it appears some of these early 2000s overclockers that helped spawned the liquid cooling renaissance may also have read A.R.S. Technical. The Intel connection
How did we get from IBM’s radiators to these days’s extravagant cooling solutions? again, thank the overclockers. around the turn of the century, liquid cooling begun catching on with pc overclockers and device builder hobbyists who desired to run their computer systems at higher speeds than formally rated. nonetheless, it become a very esoteric artwork and not using a common design. every person did their personal component. It required consumer assembly MacGyvering that put Ikea products to disgrace. many of the coolers didn’t even healthy neatly in the case.
In early 2004, things modified because of some internal politicking at Intel. An engineer from the business’s Hillsboro, Oregon, design middle—where most of the company’s chip design work is carried out, regardless of Intel HQ being in Santa Clara, California—had been working on a custom cooling challenge for Intel for a few years. The project had charge Intel greater than $1 million to develop at the moment, and its aim turned into a liquid cooler for Intel CPUs. unluckily, Intel changed into about to kill the challenge.
The engineer hoped for a special influence. To shop his undertaking, he brought the thought to Falcon Northwest, a builder of probably the greatest programs for gamers in Portland. “The reasoning turned into as an organization, they noticed liquid cooling as a tacit endorsement of overclocking, and overclocking returned then changed into verboten,” noted Kelt Reeves, president of Falcon Northwest. Intel had logical explanations for this stance. on the time, unscrupulous agents in Asia had been selling overclocked PCs at larger-than-rated clock speeds with bad cooling, and this someway grew to be Intel’s difficulty within the public discourse. as a result, the business hostile overclocking.
but this Oregon engineer notion if he may get a customer and market case for the cooler, Intel would in the end relent. (What Intel had built additionally took place to be a stronger answer than what changed into available on the market elsewhere, Reeves instructed Ars.) So after a little interior advocating and negotiating between companies, Intel allowed Falcon to sell the cooling methods—partially considering Intel had already produced hundreds of them. The most effective seize? Falcon couldn’t well known Intel’s involvement. Falcon agreed, and soon it grew to become the primary pc maker to ship a totally sealed, all-in-one-liquid cooler.
That pioneering contemporary liquid cooling answer wasn’t precisely consumer friendly, Reeves stated. Falcon needed to modify circumstances to make the radiator fit and had to invent a cold plate to chill the water. but over time, CPU cooler makers like ThermalTake and Corsair studied what Intel did and aimed for incremental advancements. From there, server products and carriers like CoolIT and Asetek sprung up to deliver liquid cooling specially to the facts center. a few of what they do—just like the tubing so that it will not smash, crack, or leak for up to seven years—turned into eventually licensed to customer CPU cooler vendors, and this sharing of advancements backward and forward has turn into the norm.
As this market began starting to be in distinct ways, even Intel at last modified its tune. It now markets the overclocking capabilities of the ok and X sequence of its CPUs, for example, and the enterprise doesn’t even trouble to provide a inventory fan with its top-of-the-line CPUs for gamers.
“[Liquid cooling] is tried and authentic—each person on the client aspect is doing it,” Reeves noted. “Intel stopped delivery stock enthusiasts with excessive-end CPUs as a result of they require liquid cooling; it’s been proven with the aid of and even blessed by Intel at this factor. I don’t feel you're going to find any person who would say an all-in-one is not reliable ample.”
For a very long time, natural information center design involved a raised flooring with tiny holes in it so cold air could come up and be sucked in to the mainframe or the server cupboard. This turned into known as a CRAC unit, for computer room air conditioner. The issue is blowing cold air via pinholes in the flooring is with no trouble now not satisfactory anymore.
in fact, the primary reason for the recent increase in the liquid cooling trade is necessity. these days’s CPUs are too hot and servers are packed too densely for air to without problems cool them anymore, as Google itself referred to. Water has approximately three,300 instances the heat means than air, and a water cooled gadget can circulation 300 liters of water per minute, as hostile to 20 cubic feet of air per minute.
To state it it appears that evidently, water can cool a good deal more efficaciously and in a a lot smaller space. So after years of making an attempt their most excellent to keep vigour consumption down, CPU carriers can now throw vigour to the wind and crank up the voltage to get highest efficiency—they comprehend liquid cooling can handle it.
“The chip degree power we're being asked to chill is accelerating past 500 watts,” noted Geoff Lyon, CEO of CoolIT. “Some CPUs not on the market yet should be hitting 300 watts. this is all being pushed via AI and computer researching. it can’t grow quick satisfactory.”further studying The AI revolution has spawned a brand new chips fingers race
Lyon spoke of CoolIT is asking at extending cooling to chipsets, vigor conditioning, networking chips, and reminiscence. “It’s now not that big a lift to move the extra distance and do RAM, too,” he delivered. “There’s flavors of RAM with advanced packaging that are 18 watts per DIMM. The ordinary DIMM is four to 6 watts. In a excessive reminiscence device, we see servers with 16, 24 DIMMs, which is a lot of heat.”
providers in all places are seeing this more and more scorching calls for. Equinix has considered its usual densities move from five kilowatts to seven or eight kilowatts and now to 15-16 watts, with some gadget in the forty kilowatt density. “So the whole volume of air to be moved via there is too substantial. It isn’t going on instantly, but the next two years may be the primary adoption of liquid cooling,” stated Equinix’s Pennington.The case for liquid cooling—energy effectivity
energy consumption has been a concern for the facts middle business for a while now (the EPA has been monitoring this for at least a decade). today's information facilities are massive facilities that eat an estimated two p.c of the global electrical power global and emit as an awful lot CO2 because the airline industry. There continues to be an overwhelming energy problem regarding this. fortunately, liquid cooling helps cut back the power bill.a short be aware on immersion green Revolution Cooling is company focusing on liquid immersion instead of direct to chip, and CEO Peter Poulin says there are two motives immersion in particular more advantageous addresses energy efficiency. First, you eradicate all the fanatics from servers when go the immersion route. by using comfortably casting off fanatics from servers, you reduce vigor servers draw on general through 15 %. One eco-friendly Revolution client reduced their vigor draw through 30 %.
Tangentially, there is yet another improvement to removing the enthusiasts: quiet. regardless of frequently using very small fans, servers are unbelievably loud and being in an information core may also be unpleasant from both a warmth and noise point of view. Liquid cooling makes them a tons extra gratifying place to work.
The subsequent huge benefit is how little vigour is required to run the immersion cooling system. It has just three moving components: a pump to flow into the coolant, a pump to stream coolant to coolant tower, and fan for cooling tower. When changing air, this may imply the electric load drops to simply five p.c of what it became on air conditioning. “so that you get this large discount in energy consumption, which enables numerous different issues,” referred to Poulin. “counting on the consumer, they can also be more energy pleasant or in the reduction of the carbon footprint linked to building more data centers.”the first mark downs comes from turning off the air conditioners in the information middle. 2d is the removing of fanatics. each server rack from 1U up has numerous fanatics in them to movement air, however that may also be reduced to little or none, counting on the density.
And with a strategy called dry cooling, which omits refrigeration, even enhanced rate reductions will also be attained. initially, direct to chip cooling circulated the water via a refrigerator which cooled the water method down, to about 15-25 degrees Celsius. nevertheless it was eventually accompanied that liquid coolers simply let the water snake via a long set of piping and fans cooled the pipes as they heated up from the scorching water, natural thermal diffusion would additionally cool the water down ample to be beneficial.
“since it’s so efficient, you don’t have to worry about water temperature being as cold as they could be,” mentioned Equinix’s Pennington. “heat water cooling nevertheless captures the entire heat from the servers somewhat comfortably. You don’t want compression cycle, that you would be able to just use dry coolers.”
Dry coolers additionally store water. a huge statistics core can eat tens of millions of gallons of water per year if it uses refrigeration, but an information middle using dry coolers doesn’t use any water. That saves vigour and water, which can be very advantageous if the facts middle is in a municipal enviornment.
“We’re now not taking in a lot of water,” mentioned Pennington. “if you design it carefully, it’s a closed loop system. There isn't any water flows in and out, just make up water to preserve the tanks topped off about yearly. You don’t correct off the water in your motor vehicle all of the time, you wouldn’t do it right here either.”the place efficiency lives, adoption follows
As just one real-world illustration: after adopting liquid cooling ideas, Dell followed up to a 56 percent improvement in PUE, or vigor usage Effectiveness, in response to Brian Payne, vice chairman of product administration and advertising and marketing for PowerEdge at Dell EMC. The PUE is the ratio of energy essential to chill the techniques versus the power obligatory to run them. A PUE of three skill it takes twice as a lot energy to cool the systems as to run them, while a PUE of 2 potential an equal quantity of energy is required to both run and cool the systems. A PUE of 1 is not possible because some sort of cooling is required, but getting the PUE right down to as near 1.0 is a close obsession amongst statistics center operators.
besides the PUE, Dell sees its liquid-cooling adoptive valued clientele getting as much as 23 percent more compute power with no need to overhaul the cooling device. “in keeping with the investment required to carry it, we forecast a one-year ROI,” Payne says. “i'd liken it to buying an improved efficiency air conditioner on your domestic. You invest a little bit but see the payback within the vigour invoice over time.”
To accept as true with a very distinctive new liquid-cooling believer, take the Ohio Supercomputer center (OSC). It runs 1,800 nodes total in a cluster. but after adopting liquid cooling, Doug Johnson, chief systems architect and HPC techniques neighborhood supervisor, spoke of the middle has hit a PUE of 1.5. OSC uses an outside loop so the water is routed out of the constructing to be cooled by means of the natural ambient temperature, which averages 30C in the summertime and a great deal less in iciness. And with the chips hitting 70C, despite the fact that the water hits 40C, that’s nonetheless a whole lot cooler than the chip and serves its aim.
Like so many early adopters, OSC became completely new to this. It went from now not doing any liquid cooling 5 years in the past to 25 percent cooling these days. It hopes to have 75 percent liquid cooling in three years and be entirely liquid cooled just a few years after that. Even with today’s reduced setup, Johnson talked about it took four instances as a great deal power to chill the systems earlier than relocating to liquid cooling, and he claims the answer has reduced the typical energy consumption through two-thirds. “I believe that percentage will handiest increase in time as we get GPUs integrated into the cooling gadget.”
From any customer’s standpoint, it takes time and energy to consider any more recent technology—it’s why massive groups like Dell have even partnered with CoolIT when it comes to making the liquid cooling sales pitch. now not particularly, worry of leaks is still the first component valued clientele tend to convey up. however hesitations apart, it turns out there isn’t a good deal of a decision as existing if you need the optimal efficiency.
“That leak concern has always existed,” spoke of CoolIt’s Lyon. “What’s changed is you don’t produce other options. for top efficiency computing, you just can’t do it with air.”

Lithium is one of the smallest, simplest, and oldest elements, but it has been tapped to unlock some big, messy problems. It's a key ingredient in the batteries that power smartphones, laptops, and electric cars. But it's also proven to be one of the most effective treatments for bipolar disorder, and recent research may make lithium the key to unlocking the causes of that illness.1. THE MAN WHO DISCOVERED LITHIUM GAVE UP SCIENCE SOON AFTER.
In 1800, Brazilian naturalist José Bonifácio de Andrada e Silva discovered petalite, a rare gem-quality mineral found in granite, on the island of Utö, Sweden. He found that the rock had a strange quality: When thrown into a fire, it created intense crimson flames. In 1817, a 25-year-old Swedish aristocrat-turned-chemist named Johan August Arfvedson discovered lithium while analyzing petalite. Arfvedson identified the culprit for the red flames by process of elimination: Having recognized most of the mineral's content as silica and aluminum, he deduced a new alkali metal made up the remaining share. It was Arfvedson's only recorded discovery; he soon retired from chemistry to manage his inherited fortune.
Lithium was later isolated in its elemental metal form using electricity. That process, electrolysis, is still used in lithium production.2. LITHIUM IS BORN IN STELLAR EXPLOSIONS—WHICH WE ONLY LEARNED IN 2013.
Hydrogen, helium, and lithium, the first three elements in the periodic table, were all created in the Big Bang, but the first two elements are abundant, and lithium is not. Astrophysicists had a theory that novae, or stellar explosions, were responsible for lithium's scant distribution in the universe, but they didn't have data for how that worked until Nova Centauri's December 2013 explosion—visible to the naked eye, if your eyes were in the southern hemisphere. Researchers witnessed the dying star ejecting lithium into space.3. ITS SOURCES ARE LIMITED.
More than half of the world's lithium supply comes from high-altitude lakes and bright white salt flats in the "lithium triangle" in Bolivia, Chile (as seen above), and Argentina, where it's mined in a grid of brine pools. In other regions, it comes from open-pit mines spiraling into layers of earth. Deposits have also been found in Australia, in the Tibetan portion of China, and in the U.S. in North Carolina and Nevada. Between 2015 and 2016, the price per ton of the commodity more than tripled, leading the UK to search for domestic supplies. At the current pace, according to consulting company Stormcrow Capital, demand for lithium could outpace production by 2023. To get around this looming shortage, some researchers are developing ways to recycle used lithium-ion batteries.4. LITHIUM IS NEVER FOUND ALONE.
Lithium doesn't range freely through nature, but instead has to be isolated from other minerals. Often, it's sourced from petalite (above). It's found in traces in almost all igneous rocks and in many mineral springs. Those who swim in lithium-infused hot springs are often told that it has curative powers, including improved brain function and elevated mood—though there's no evidence of this.5. IT POWERS MANY OF YOUR DEVICES.
Lithium has several advantages that make it the go-to for powering everything from smartphones to hybrid cars. It's the lightest known metal, which means it can store power without adding a lot of weight to devices. Lithium-ion batteries also have some of the highest energy densities of any current battery technology; they deliver three times the voltage of nickel-based batteries, according to the University of Washington's Clean Energy Institute.
But those aren't lithium's only advantages. Many nickel-based batteries experience what's known as the "memory effect"—if they're repeatedly plugged in to charge before they're fully dead, they'll lose power capacity (so instead of remembering its full capacity, the battery will only remember half, for example). But that's not the case with lithium-ion batteries, which are believed to have no memory effect.6. IT'S KEY TO IMPROVING ELECTRIC VEHICLES …
Current electric vehicle models require recharging after around 300 miles of driving. Given the limited number of re-charging stations available around the nation, that could make for tough logistics on cross-country road trips. So the Department of Energy is funding battery research to improve that range and has recruited five universities, three national laboratories, and IBM to the Battery500 Consortium to develop smaller, lighter, more efficient batteries that could, among other potential uses, increase the range of electric cars.
"If we're successful, we'll be able to double the range of electronic vehicles today. This by itself is extremely challenging," says Jihui Yang, chair of the University of Washington's department of Materials Science and Engineering.
Yang and his collaborators aim to replace the graphite currently used in the negative electrode of lithium-ion batteries with lithium metal. Doubling the use of lithium would significantly increase the power output of those batteries. To do so, though, they'll have to solve a big problem: In the all-lithium batteries that currently exist, lithium grows needle-like dendrites that can puncture the separator—a thin layer of porous polymer separating the negative and positive sides of a battery—causing the battery to short.7. … AND HAS SET PLANES AND PHONES ON FIRE.

Battery shorts can be more than just annoying—they can be incendiary. Some Boeing airplanes use lithium-ion batteries to power up their jet engines, and the quickly recharged batteries then serve as a backup power supply for electrical systems. But the Federal Aviation Administration grounded the entire Boeing 787 Dreamliner fleet in 2013 after one plane's lithium-ion battery shorted out and started a fire—shortly after passengers had disembarked in Boston—and a battery malfunction warning went off in another plane.
Tesla Model S cars also saw fires in 2013 attributed to battery malfunctions. Then the Samsung Galaxy Note 7 phones started catching fire, prompting the FAA to ban the phones from flights. Samsung had tried to boost battery capacity to accommodate consumers' increasing game-playing and video-streaming habits while also shrinking the phone. Tasked with doing more in a smaller size, it became prone to meltdowns.
There's a reason why the batteries are so combustible. Lithium ions pass through the tiny holes in the separator between the positive and negative electrodes of the battery, carried by a liquid electrolyte solution. But if the separator is damaged—like by dropping your phone—or the chemistry underway is changed by the heat of recharging or sitting in the sun, the equation changes. The outputs of those changed chemical reactions include flammable gases, and lithium itself can also ignite in humid air. The Federal Aviation Administration now requires spare rechargeable lithium batteries be transported in carry-on baggage. If a fire from a cell phone or laptop battery starts on board, the FAA has advised flight attendants to use water or soda to extinguish it, though a foam extinguisher or dry chemical fire extinguisher can also be used.8. IT'S USED TO TREAT MENTAL ILLNESSES …
Lithium has been used for more than a century to treat bipolar disorder and other mental illnesses, including depression, schizophrenia, and eating disorders. It's also used to treat anemia, headaches, alcoholism, epilepsy, and diabetes. But there's a narrow difference between the dose at which it's effective and the one at which it is lethal.
"It's not that people don't know what lithium does in general, the problem is that it does too many things," says Evan Snyder, a professor in the human genetics program with Sanford Burnham Prebys Medical Discovery Institute, who studied the disorder as part of research on defects that involve more than one abnormal gene. He likens prescribing lithium to using a sledgehammer on a nail; there's a lot of collateral damage. "What we'd like is a very tiny, mini hammer just to precisely hit exactly what it is that lithium is doing," he tells Mental Floss.
But first, scientists needed to know which nail to swing for, and for that, Snyder studied lithium's affects in the brain. Research Snyder published in 2017 details how the drug works to regulate connections in the brain's nerve cells. Now, he says, that effect can be compared with other drugs to search for a more targeted treatment; right now, it works on only one out of every three patients.9. … BUT THERE CAN BE LONG-TERM SIDE EFFECTS.
At age 17, Jaime Lowe believed her parents were secret agents, saw the Muppets heckling her, and thought she could converse with Michael Jackson and follow secret tunnels to Neverland. She was soon diagnosed as bipolar, and daily doses of lithium stabilized the manic episodes; without it, as she wrote in a New York Times essay about her life on the drug, she'd be "riding on top of subway cars measuring speed and looking for light in elevated realms." About one-third of people with bipolar disorder see their symptoms relieved by lithium.
But that can come at a price. Lithium's side effects include weight gain, nausea, and the exacerbation of heart and kidney disease. In Lowe's case, after 20 years of taking the drug, she began to have spiking blood pressure and other signs of kidney failure. Her doctor gave her a choice between switching off the drug that had given her a functional life—or getting a kidney transplant. She chronicles the experience—and her trip to Bolivia to hike the salt flats where lithium is mined—in her 2017 book Mental: Lithium, Love, and Losing My Mind.10. LITHIUM WAS ONCE A KEY INGREDIENT IN 7 UP.
Before "7 Up" became its name and holiday party punchbowls everywhere became its prime target, the soft drink, which debuted in 1929, was briefly called "Bib-Label Lithiated Lemon-Lime Soda," and its original ingredients included lithium citrate. To make its product stand out in a sea of 600 lemon-lime soft drinks already on the market, Cadbury Beverages North America touted the supposedly positive health effects of the lithium in the soda, which was released just weeks before the 1929 stock market crash and the onset of the Great Depression. Apparently the recipe had some appeal: In the 1940s: 7 Up was the third best-selling soft drink in the world, according to Cadbury. (Look how happy the family above seems in this ad from the March 1948 issue of The Ladies' Home Journal.) Lithium was included in its recipe until 1950.
Sir Tim Berners-Lee, the inventor of the World Wide Web, has worked along with many others in the internet community for more than a decade to achieve his next big dream: the semantic web. His vision is a web that allows software agents to carry out sophisticated tasks for users, making meaningful connections between bits of information so that “computers can perform more of the tedious work involved in finding, combining, and acting upon information on the web.”
Some 895 experts responded to the invitation of the Pew Research Center’s Internet & American Life Project and Elon University’s Imagining the Internet Center to predict the likely progress toward achieving the goals of the semantic web by the year 2020. Asked to think about the likelihood that Berners-Lee and his allies will realize their vision, often called Web 3.0, these technology experts and stakeholders were divided and often contentious.
Some 47% agreed with the statement:
Some 41% agreed with the opposite statement, which posited:
Experts generally agreed that progress will continue to be made in making the web more useful and information retrieval and assessment more meaningful. They recognized the fact that there are already elements and programs of the semantic web in place that are helping people more easily navigate their lives. While many survey participants noted that current and emerging technologies are being leveraged toward positive web evolution in regard to linking data, there was no consensus on the technical mechanisms and human actions that might lead to the next wave of improvements – nor how extensive the changes might be.
Many think Berners-Lee’s vision will take much longer to unfold than the 2020 timeline posited by the question. Critics noted that human uses of language are often illogical, playfully misleading, false or nefarious, thus human semantics can never be made comprehensible to machines. Some 12% of those who responded to the survey did not venture a guess about the future of the semantic web – itself a sign that there is still a good deal of uncertainty and confusion about the topic even among those who are quite connected to the tech world.

This material was gathered in the fourth “Future of the Internet” survey conducted by the Pew Research Center’s Internet & American Life Project and Elon University’s Imagining the Internet Center. The surveys are conducted through online questionnaires to which a selected group of experts and the highly engaged internet public have been invited to respond. The surveys present potential-future scenarios to which respondents react with their expectations based on current knowledge and attitudes. You can view detailed results from the 2004, 2006, 2008 and 2010 surveys here: http://www.pewinternet.org/topics/Future-of-the-internet.aspx and http://www.elon.edu/e-web/predictions/expertsurveys/default.xhtml. Expanded results are published in the “Future of the Internet” series published by Cambria Press.
Respondents to the Future of the Internet IV survey, fielded from Dec. 2, 2009 to Jan. 11, 2010, were asked to consider the future of the internet-connected world between now and 2020 and the likely innovation that will occur. They were asked to assess 10 different “tension pairs” – each pair offering two different 2020 scenarios with the same overall theme and opposite outcomes – and they were asked to select the one most likely choice of two statements. The tension pairs and their alternative outcomes were constructed to reflect previous statements about the likely evolution of the internet. They were reviewed and edited by the Pew Internet Advisory Board. Results are being released in four venues over the course of 2010.
The results that are reported here are responses to a tension pair that relates to the future impact of the internet on institutions and organizations. Results to five other tension pairs – relating to the internet and the evolution of intelligence; reading and the rendering of knowledge; identity and authentication; gadgets and applications; and the core values of the internet – were released earlier in 2010 at the meeting of the American Association for the Advancement of Science. They can be read at: http://www.pewinternet.org/Reports/2010/Future-of-the-Internet-IV.aspx. Additional results from the tension pair involving the impact of the internet on institutions were discussed at the Capital Cabal in Washington, DC, on March 31, 2010 and can be read at: http://www.pewinternet.org/Reports/2010/Impact-of-the-Internet-on-Institutions-in-the-Future.aspx.
Still other results will be released at the 2010 World Future Society conference (http://www.wfs.org/meetings.htm).
Please note that this survey is primarily aimed at eliciting focused observations on the likely impact and influence of the internet – not on the respondents’ choices from the pairs of predictive statements. Many times when respondents “voted” for one scenario over another, they responded in their elaboration that both outcomes are likely to a degree or that an outcome not offered would be their true choice. Survey participants were informed that “it is likely you will struggle with most or all of the choices and some may be impossible to decide; we hope that will inspire you to write responses that will explain your answer and illuminate important issues.”
Experts were located in two ways. First, several thousand were identified in an extensive canvassing of scholarly, government, and business documents from the period 1990-1995 to see who had ventured predictions about the future impact of the internet. Several hundred of them participated in the first three surveys conducted by Pew Internet and Elon University, and they were recontacted for this survey. Second, expert participants were hand-picked due to their positions as stakeholders in the development of the internet.
Here are some of the respondents: Clay Shirky, Esther Dyson, Doc Searls, Nicholas Carr, Susan Crawford, David Clark, Jamais Cascio, Peter Norvig, Craig Newmark, Hal Varian, Howard Rheingold, Andreas Kluth, Jeff Jarvis, Andy Oram, Kevin Werbach, David Sifry, Dan Gillmor, Marc Rotenberg, Stowe Boyd, Andrew Nachison, Anthony Townsend, Ethan Zuckerman, Tom Wolzien, Stephen Downes, Rebecca MacKinnon, Jim Warren, Sandra Brahman, Barry Wellman, Seth Finkelstein, Jerry Berman, Tiffany Shlain, and Stewart Baker.
The respondents’ remarks reflect their personal positions on the issues and are not the positions of their employers, however their leadership roles in key organizations help identify them as experts. Following is a representative list of some of the institutions at which respondents work or have affiliations: Google, Microsoft. Cisco Systems, Yahoo!, Intel, IBM, Hewlett-Packard, Ericsson Research, Nokia, New York Times, O’Reilly Media, Thomson Reuters, Wired magazine, The Economist magazine, NBC, RAND Corporation, Verizon Communications, Linden Lab, Institute for the Future, British Telecom, Qwest Communications, Raytheon, Adobe, Meetup, Craigslist, Ask.com, Intuit, MITRE Corporation
Department of Defense, Department of State, Federal Communications Commission, Department of Health and Human Services, Centers for Disease Control and Prevention, Social Security Administration, General Services Administration, British OfCom, World Wide Web Consortium, National Geographic Society, Benton Foundation, Linux Foundation, Association of Internet Researchers, Internet2, Internet Society, Institute for the Future, Santa Fe Institute, Yankee Group
Harvard University, MIT, Yale University, Georgetown University, Oxford Internet Institute, Princeton University, Carnegie-Mellon University, University of Pennsylvania, University of California-Berkeley, Columbia University, University of Southern California, Cornell University, University of North Carolina, Purdue University, Duke University , Syracuse University, New York University, Northwestern University, Ohio University ,Georgia Institute of Technology, Florida State University, University of Kentucky, University of Texas, University of Maryland, University of Kansas, University of Illinois, Boston College, University of Tulsa, University of Minnesota, Arizona State, Michigan State University, University of California-Irvine, George Mason University, University of Utah, Ball State University, Baylor University, University of Massachusetts-Amherst, University of Georgia, Williams College, and University of Florida.
While many respondents are at the pinnacle of internet leadership, some of the survey respondents are “working in the trenches” of building the web. Most of the people in this latter segment of responders came to the survey by invitation because they are on the email list of the Pew Internet & American Life Project or are otherwise known to the Project. They are not necessarily opinion leaders for their industries or well-known futurists, but it is striking how much their views were distributed in ways that paralleled those who are celebrated in the technology field.
While a wide range of opinion from experts, organizations, and interested institutions was sought, this survey should not be taken as a representative canvassing of internet experts. By design, this survey was an “opt in,” self-selecting effort. That process does not yield a random, representative sample. The quantitative results are based on a non-random online sample of 895 internet experts and other internet users, recruited by email invitation, Twitter, or Facebook. Since the data are based on a non-random sample, a margin of error cannot be computed, and results are not projectable to any population other than the respondents in this sample.
Many of the respondents are internet veterans – 50% have been using the internet since 1992 or earlier, with 11% actively involved online since 1982 or earlier. When asked for their primary area of internet interest, 15% of the survey participants identified themselves as research scientists; 14% as business leaders or entrepreneurs; 12% as consultants or futurists, 12% as authors, editors or journalists; 9% as technology developers or administrators; 7% as advocates or activist users; 3% as pioneers or originators; 2% as legislators, politicians or lawyers; and 25% specified their primary area of interest as “other.”
The answers these respondents gave to the questions are given in two columns. The first column covers the answers of 371 longtime experts who have regularly participated in these surveys. The second column covers the answers of all the respondents, including the 524 who were recruited by other experts or by their association with the Pew Internet Project. Interestingly, there is not great variance between the smaller and bigger pools of respondents.
