SpaceX Dragon returns to Earth, ends historic trip


CAPE CANAVERAL, Fla. (AP) — Triumphant from start to finish, the SpaceX Dragon capsule parachuted into the Pacific on Thursday to conclude the first private delivery to the International Space Station and inaugurate NASA's new approach to exploration.
"Welcome home, baby," said SpaceX's elated chief, Elon Musk. The old-fashioned splashdown was "like seeing your kid come home," he said.
He said he was a bit surprised to hit such a grand slam.
"You can see so many ways that it could fail and it works and you're like, 'Wow, OK, it didn't fail,'" Musk said, laughing, from his company's headquarters in Hawthorne, Calif. "I think anyone who's been involved in the design of a really complicated machine can sympathize with what I'm saying."
The goal for SpaceX will be to repeat the success on future flights, he told reporters.
The unmanned supply ship scored a bull's-eye with its arrival, splashing down into the ocean about 500 miles off Mexico's Baja California peninsula. A fleet of recovery ships quickly moved in to pull the capsule aboard a barge for towing to Los Angeles.

It was the first time since the shuttles stopped flying last summer that NASA got back a big load from the space station, in this case more than half a ton of experiments and equipment.
Thursday's dramatic arrival of the world's first commercial cargo carrier capped a nine-day test flight that was virtually flawless, beginning with the May 22 launch aboard the SpaceX company's Falcon 9 rocket from Cape Canaveral and continuing through the space station docking three days later and the departure a scant six hours before hitting the water.

The returning bell-shaped Dragon resembled NASA's Mercury, Gemini and Apollo spacecraft of the 1960s and 1970s as its three red-and-white striped parachutes opened. Yet it represents the future for American space travel now that the shuttles are gone.
"This successful splashdown and the many other achievements of this mission herald a new era in U.S. commercial spaceflight," NASA Administrator Charles Bolden said in a statement.
Alan Lindenmoyer, manager of NASA's commercial crew and cargo program, was emotional as he turned to Musk and assured him that NASA was now his customer and that resupply services were about to unfold on a regular basis.
"You have turned those hopes into a reality," Lindenmoyer said.
Noted Musk: "It really shows that commercial spaceflight can be successful. I mean, this mission worked first time right out the gate."

Musk, the billionaire behind PayPal and Tesla Motors, aims to launch the next supply mission in September under a steady contract with NASA, and insists astronauts can be riding Dragons to and from the space station in as little as three or four years. The next version of the Dragon, for crews, will land on terra firma with "helicopter precision" from propulsive thrusters, he noted. Initial testing is planned for later this year.

President Barack Obama is leading this charge to commercial spaceflight. He wants routine orbital flights turned over to private business so the space agency can work on getting astronauts to asteroids and Mars. Toward that effort, NASA has provided hundreds of millions of dollars in seed money to vying companies.
NASA astronauts are now forced to hitch rides on Russian rockets from Kazakhstan, an expensive and embarrassing outsourcing, especially after a half-century of manned launches from U.S. soil. It will be up to SpaceX or another U.S. enterprise to pick up the reins. Several companies are jockeying for first place.

It will take a few days to transport the fresh-from-orbit Dragon by barge to the Port of Los Angeles. From there, it will be trucked to the SpaceX rocket factory in McGregor, Texas, for unloading and inspection. Reports from the scene are that the spacecraft looks "really good," Musk said, with no major changes needed for future Dragons, just minor tweaks.
SpaceX — or more properly Space Exploration Technologies Corp. — plans to hustle off a few returning items while still at sea to demonstrate to NASA a fast 48-hour turnaround. That capability would be needed for future missions bearing vital experiments.

The capsule returned nearly 1,400 pounds of old space station equipment and some science samples, a little more than it took up. Because it was a test flight, NASA did not want to load it with anything valuable. It carried up mostly food.

This was only the second time a Dragon has returned from orbit. In December 2010, SpaceX conducted a solo-flying shakedown cruise. Like the Dragon before it, this capsule will likely become a traveling exhibit.

Russia's Soyuz capsules for carrying crews also parachute down but on land, deep inside Kazakhstan. All of the government-provided cargo vessels of Russia, Europe and Japan are filled with station garbage and burn up on descent.
NASA lost the capability of getting things back when its shuttles were retired last July.
Rival Orbital Sciences Corp. hopes to have its first unmanned test flight off by year's end, launching from Wallops Island in Virginia. It, too, has a NASA contract for cargo runs.
The grand prize, though, will involve getting American astronauts flying again from U.S. soil and, in doing so, restore national prestige.

Aboard the space station is a small U.S. flag that soared on the first shuttle mission in 1981 and returned to orbit with the final shuttle crew. It will go to the first private rocket maker to arrive with a U.S.-launched crew.
After that, promises Lindenmoyer, there will be more opportunities for partnering NASA and industry — perhaps at the moon, Mars or beyond.
The Commercial Spaceflight Federation considers the Dragon's success a critical stepping stone. "It's a seminal moment for the U.S. as a nation, and indeed for the world," said its chairman, Eric Anderson.




ermany Sets New Solar Record By Meeting Nearly Half of Country’s Weekend Power Demand

Germany fed a whopping 22 gigawatts of solar power per hour into the national grid last weekend, setting a new record by meeting nearly half of the country’s weekend power demand. After the Fukushima disaster, Japan opted to shut down all of its nuclear power stations and Germany followed suit after considerable public pressure. This seems to have paved the way for greater investment in solar energy projects. The Renewable Energy Industry (IWR) in Muenster announced that Saturday’s solar energy generation met nearly 50 percent of the nation’s midday electricity needs AND was equal to 20 nuclear power stations at full capacity!
germany solar power, germany 2020 goals, eu 2020 goals, germany nuclear power, renewable energy industry, solar power record, germany solar industry
Germany’s solar power industry has always been a world leader, but since the the country closed eight nuclear power plants after the Japanese disaster and announced they would be shutting down the remaining nine by 2022, pressure to find alternative energy has mounted. Other sources such as wind and biomass are expected to pick up the slack, but solar power has never been more important.
By meeting a third of its electricity needs on a work day and nearly half on Saturday when factories and offices were closed, Germany’s solar power industry has broken all previous records. Speaking to Reuters, Norbert Allnoch, director of the IWR said: ”Never before anywhere has a country produced as much photovoltaic electricity. Germany came close to the 20 gigawatt (GW) mark a few times in recent weeks. But this was the first time we made it over.”
“This shows Germany is capable of meeting a large share of its electricity needs with solar power,” Allnoch said. “It also shows Germany can do with fewer coal-burning power plants, gas-burning plants and nuclear plants.” By receiving government-mandated support for renewables, Germany has became a world leader in renewable energy. Currently the country gets about 20% of its overall annual electricity from renewable sources and has nearly as much installed solar power generation capacity as the rest of the world combined. Like most other European countries, it is aiming to cut its greenhouse gas emissions by 40% from 1990 levels by 2020, but at this rate it is the country most likely to actually follow through.

Paralyzed Rats Walk Again, Thanks to Electricity, Chemicals—And Chocolate

First recovery of severely injured spinal cords—may hold hope for people.

Wearing a robotic harness, paralyzed rats have been made to walk again, according to a new studyalbeit with an oddly upright, humanlike gait and while stimulated by judicious jolts of electricity and chemicals.

It's the first time severely injured spinal cords have been reawakened, say researchers, who add that the technique might hold some promise for disabled people.


First, neuroscientist GrĂ©goire Courtine and his team severed the spines of 27 rats, leaving some tissue intact but no direct nerve connections—and therefore no way for the animals to control their hind legs.
A week later the researchers put 17 of the rats on a sort of physical therapy regimen and began administering chemical injections and electric stimulation directly to the rodents' spinal cords. The remaining ten rats, used as a control group, received no treatment. (Also see "Stem Cells Repair Damaged Spinal Cords in Mice.")


The physical training began on a treadmill, with the 17 rats using a robotic harness—created especially for the study—that suspended the animals upright but did not propel them forward.
The treadmill exercise exploited reflexes that make walking in some ways passive, explained neuroscientist Naomi Kleitman of the U.S. National Institutes of Health (NIH).
"Imagine you can't get any signals from your brain to below the injury—you can still walk on a treadmill," said Kleitman, who wasn't part of the new study.
"The treadmill is dragging my right foot behind me," she added. "That will stimulate a reflex in my left leg that will make my left leg take a step."
(Related pictures: Paralyzed rats move again after food-dye injections.)

Anything for Chocolate?
In addition to the treadmill therapy, the trained rats received mild electrical stimulation—designed to mimic the signals the brain sends to move the legs—and injections of chemicals known to help nerve cells, which carry those signals, to better communicate.
After three weeks of treadmill training, 10 of the 17 rats were encouraged to take steps on a sort of tiny runway—still in the harnesses, though, and still being electrochemically stimulated.
Within a few more weeks—and with the incentive of a bit of chocolate at the end of the course—the runway rats were "sprinting" up stairs in their harnesses, study co-author Courtine said in a statement.
Though the rats still couldn't walk unaided, they had undergone a "nearly complete" regrowth of spinal nerve fibers, reestablishing the severed connections between brain and haunches, the study says. The effect was seen only the rats that had undergone training on solid ground—the untrained and treadmill-only rodents failed to regain voluntary movement in their paralyzed legs.
(Related: "Worms' Paralysis Turned On and Off With Light.")

Hope for People?
All these treatments are already being tested in people, NIH's Kleitman said. What makes the study exciting is that the methods have never before been tried in combination.
The electrochemical cocktail, she said, is what "to me, made this paper quite relevant, even though it's just in rats."
Mayo Clinic neurologist Tony Windebank agreed. "All the things they are doing in rats are things you can do in people."
He cautioned, however, that stimulating and enhancing the automatic walking reflex is "much easier to do in quadrupeds compared to upright animals."
But, he said, "I think it's an important step forward," even if "it's not the giant step for mankind—it's not going to translate to, Let's do this in people next month and have them walking."
Kleitman believes the severity of the rats' paralysis and subsequent recovery should give some people hope.
"Some people might say it's not worth doing anything with" severely paralyzed people, "because there's almost nothing left," she said. "Studies like this one show it's worth trying."
The paralyzed-rats study will be published in the June 1 issue of the journal

The energy transition juggernaut

By | May 16, 2012, 2:37 AM PDT


Poll after poll show that citizens of the Western world want more renewable power and are willing to pay for it. So what’s the hold-up?
A new poll conducted by Yale and Harvard researchers and published in the science journal Nature this week found that the average U.S. citizen is willing to pay between $128 and $260 more per year in electricity bills ($162 on average, or 13 percent more) to achieve 80 percent clean energy by 2035. Support varies by demographics, of course—it’s lower among Republicans, people of color, and older individuals—and support drops further if the clean energy standard includes nuclear power and natural gas. As a practical matter, the researchers found in a voting simulation that the cost increase would have to be under $48 a year to pass the House, and under $59 a year to be filibuster-proof in the Senate. Even so, it’s clear that the overwhelming majority of Americans and their elected representatives would support the “80 percent by 2035″ standard if it increased electricity prices by less than 5 percent.
Similarly, clean air enjoys overwhelming bipartisan support among U.S. voters. In October last year, a poll of 1,400 voters by Hart Research and GS Strategy Group found that, “by a wide margin, voters of both political parties and in all regions of the U.S. disagree with Congress’ anti-Environmental Protection Agency (EPA) agenda and support the EPA’s new rules to limit air pollution from coal-fired power plants.” A whopping 88 percent of Democrats, 85 percent of Independents, and 58 percent of Republicans opposed Congressional attempts to delay implementation of the rules, and 79 percent of voters supported the rules due to health concerns about polluted air. “Regardless of affiliation, voters want a healthy environment and an end to foot-dragging to upgrade dirty power plants. Despite the rhetoric in Washington, clean air is not a partisan issue among Americans, and Congress would do well to take notice,” said Mindy Lubber, president of sustainability advocacy group Ceres, which sponsored the poll.
One might well ask why Congress does not seem to have so noticed, but we’ll get to that in a moment.
Another poll by ORC International of 1,019 Americans, released in April this year and conducted by the non-partisan Civil Society Institute, found that 77 percent of Americans surveyed, including 65 percent of the Republicans, believe “the U.S. needs to be a clean energy technology leader and it should invest in the research and domestic manufacturing of wind, solar and energy efficiency technologies.” When given a choice between subsidizing either renewables or fossil fuels only, three times as many respondents chose renewables.
More significantly, respondents were clearly looking beyond their pocketbooks, even while struggling with high gasoline prices. More than two-thirds of respondents said that progress toward clean energy should not be ‘put on hold’ due to ongoing economic problems. Fully 76 percent of Republicans, 87 percent of Independents, and 91 percent of Democrats agreed with the statement “energy development should be balanced with health and environmental concerns,” while only 13 percent said that “health and environmental concerns should not block energy development.”
Two-thirds of respondents in the ORC International poll believe that “political leaders should help to steer the U.S. to greater use of cleaner energy sources - such as increased efficiency, wind and solar - that result in fewer environmental and health damages.” But when framed as a jobs issue, rather than a health and environment issue, support zooms higher.
That conclusion came from a comprehensive analysis of international and U.S. polls on “the world’s most pressing challenges,” released in January by the Council on Foreign Relations’ International Institutions and Global Governance program and worldpublicopinion.org. It found that 91 percent of Americans believed that investing in renewable energy was important for the U.S. to remain competitive on the global stage, and that 80 percent favored strong tax incentives for renewables as a way to cut dependence on foreign energy sources.
Further, it found that three-quarters of the American public believes the U.S. government “should assume that oil is running out and will need to be replaced as a primary source of energy,” and that large majorities are worried about environmental damage, and the destabilizing effects of impending energy shortages and higher prices.
The same analysis found that clear majorities in all 27 members of the European Union approved of increasing the share of renewable energy to 20 percent or more by 2020, and believed that they would be personally affected by the consequences of energy dependence.
Two recent opinion polls in the UK support those conclusions, finding that a majority of the public see wind power subsidies as a good deal, and a large majority favor renewable energy in general. The nation’s Renewables Obligation strategy (similar to the state Renewable Portfolio Standards in the U.S.) costs the average citizen about two pence per day, and most thought it a good value.
Australians are overwhelmingly in favor of renewables, too. A face-to-face poll of 14,000 Australians last year found that 91 percent of the public think the government should take more action to push for renewable power, and 86 percent are in favor of a plan to get to 100 percent renewables.
A new paper on the German Energy Transition found that support for nuclear power is fading across the continent, with only France, the Czech republic, and Poland still favoring it. Over 80 percent of Germans and 90 percent of Austrians are against nuclear power, but, the paper argues, this is not simply “the reaction of a spooked people to Fukushima.” Germans have favored a transition to renewables since the early 1990s, “every political party says it’s on board,” and Germans are willing to pay higher energy bills to make it happen.
But they may not have to pay more, according to a study by the Fraunhofer Energy Alliance released in July 2011. As costs for solar PV continue to drop, the researchers predict that electricity generation in Germany would fall to 11 to 14 cents per kilowatt hour as early as 2016, or about one-third the current retail price of electricity. Another cited study, “Vision for a 100 percent renewable energy system,” found that the cost of expanding renewable energy would peak in 2015, then sink; from 2010 to 2050, it projected an overall savings of 730 billion Euro.
Solar is already reducing electricity costs in Germany on a daily basis. A widely-circulated pair of graphs on the Renewables International site show that as the sun fires up solar systems around 9 am, the cost of “peak” power generation now crashes to around 35 Euro per megawatt hour, and stays there until around 6 pm. Just four years ago, peak power prices in Germany held firmly around 55 to 60 Euro over the same hours. As Australian journalist Giles Parkinson observed, “solar PV is not just licking the cream off the profits of the fossil fuel generators. . . it is in fact eating their entire cake.”
Further, the net impact of energy transition would result in more jobs, and a greater benefit to the overall economy. “The negative impact of a shift to alternative energy is far outweighed by the remaining positive net effect of some 400,000 additional jobs in the EU as a whole,” the Fraunhofer study says, and moreover, “Europe’s GDP is expected to grow by 0.24 % (some 35 billion Euro).” Another cited study showed that transition to renewables would result in a net new 120,000 to 140,000 jobs, after “all negative effects and influences on the economic cycle are taken into account.” Across the EU, some 2.8 million people are expected to find jobs in Europe’s renewable energy sector by 2020.

The rise of the precautionary principle

The public has clearly become sensitized to the risks of producing fossil fuels from our remaining, increasingly marginal resources. The last several years have offered a handful of hard object lessons: The Deepwater Horizon blowout in the Gulf of Mexico, and its lingering effects on the ecosystem, replete with the ongoing spectacle of eyeless shrimp, clawless crabs and fish with lesions. A series of reports about water contaminated by shale fracking activities, with tone-deaf industry responses. Small towns turned upside-down by the sudden influx of trucks and roughnecks drilling for shale oil and gas. Even nuclear power is now suspect after the specter of the Fukushima plant meltdown, with low levels of its radiation turning up in California a few days later.
Is it any surprise that the public is becoming risk-averse, and embracing renewables as never before?
An overwhelming majority of citizens now support the “precautionary principle”: Rather than letting industry do whatever it wants and putting the burden on the public to prove that those activities are risky or damaging to the environment and the public health, voters would rather put the onus on industry to show that its activities are safe before being allowed to proceed.
As Steve Coll points out in his excellent new book, Private Empire: ExxonMobil and American Power, the company has prosecuted a long war against the precautionary principle. He traces the popular rise of the concept back to the West German environmental movement of the 1970s, where it was known as Vorsorge (precaution). In his chapter on the ExxonMobil chemical division’s fight to preserve the use of phthalates (plastic softeners) in children’s toys, he cites a company slide deck claiming that “Politics, not science, is the reason” for a proposed ban on the chemicals, and observes that “‘Politics,’ however, was in fact a synonym for the rise of the precautionary principle as a popularly supported basis of chemical regulation in Europe—and there was little reason to believe that philosophy would remain sequestered there.”
Indeed, it has not. The ORC International survey found that more than two-thirds of Americans, including 60 percent of Republicans, 76 percent of Independents, and 74 percent of Democrats, think the precautionary principle should guide our energy future. But ExxonMobil remains staunchly opposed. In an article in Fortune last month, CEO Rex Tillerson sneered that precautionary principle “will absolutely undermine the economy,” adding, “If you want to live by the precautionary principle, then crawl up in a ball and live in a cave.”

A political boomerang

The fossil fuel industry seems to believe that ratcheting up their rhetoric and blowing huge wads of cash on disinformation campaigns can tilt the odds back into their favor, but with enormous majorities of Western citizens now looking to renewables, I suspect those efforts will backfire.
One week ago, the Guardian broke a story about a confidential memo showing that a network of right-wing organizations in the U.S. were planning a national PR campaign to cause “subversion in message of industry so that [wind power] effectively because [sic] so bad that no one wants to admit in public they are for it.” National advocacy groups funded by the fossil fuel industry, including several organizations backed by the oil and coal industry billionaire baron brothers Koch, were identified as the source. The documents suggested setting up “dummy businesses” to hide the backers of anti-wind billboards, and a “counter-intelligence branch” to dog the wind industry. Further, it called for creating a tax-exempt organization with paid staffers, backed by $750,000 in funding, to persuade the public against policies favorable to wind energy.
The majority of the free world now believes that climate change is a serious problem; a Yale study released in March found that two thirds of Americans believe the planet is warming. (However, as a testament to the effectiveness of the fossil fuel industry’s disinformation campaigns thus far, just 46 percent believe that it’s due to human activities, down four points from the previous study in November 2011.) Europeans and Australians have long been running far ahead of Americans on that issue.
Despite four ardent (and expensive) decades of campaigning by the fossil fuel industry, the majority also want an electricity supply powered by renewables, and believe that remaining on the fossil fuel path poses serious risks to health, security, the economy, and the environment. It’s a modest stretch to suppose that that same majority increasingly understand that all of those issues are intrinsically intertwined.
At the same time, the Yale study found that on the global warming issue, the vast majority trust scientists; distrust the mainstream news media; distrust the oil, gas, coal, and auto companies; and distrust Mitt Romney.
It seems that money is no longer able to stop the energy transition juggernaut, at least in terms of public opinion. If our so-called representative governments actually represented us, we would have an all-out push to leave fossil fuels in the dust and build every last feasible kilowatt of renewable capacity ASAP. But they do not; they are beholden to their corporate donors. In the U.S., the fossil fuel industry still outspends the renewable industry in lobbying by about 12 to 1. “Legislative capture” is the reason why we continue to see Congress slap-fighting about a mere $4 billion in subsidies for the oil industry instead figuring out how to execute transportation transition. It’s why we still don’t have a feed-in tariff, like everyone else in the world who are serious about energy transition do. It’s why we haven’t yet taken the bit of energy transition between our teeth and run with it.
But we will. We may have to wait until the dinosaurs of the fossil fuel regime die or are voted out of office before policymakers catch up with the public. In the meantime, we’ll have to shift for ourselves, build as much renewable capacity as we can manage, and be content to throw popcorn at the TV when those glossy ads about jobs in the oil patch come on. We know better than to believe the claims of incipient energy independence. The longer our legislators defy the will of the people, the more they will lose our trust, and eventually, their lobbying support. The age of renewables is here. There is no turning back.

Beyond 'Jeopardy': How IBM will make billions from Watson

Follow @BSnyderSF

At a time when companies spend billions on patent wars and frivolous acquisitions, IBM makes money the old-fashioned way: through R&D

Like millions of others, I made a point of staying home a few nights in February 2011 to watch a computer challenge the world's best "Jeopardy" players. IBM's Watson won, of course. End of story? Just a stunt? Not at all. After about five years of development and millions in R&D spending, IBM is taking its first steps to bring Watson out of the lab (and TV studio) and make money from it.
IBM, which made Watson a unit of its very profitable software group, has already landed major clients in health care and financial services (two were announced in March), with more in the offing.

Sure, Watson has an obvious cool factor. Haven't we been waiting since "2001: A Spce Odyssey" for a computer that could really understand human speech and use the knowledge to do something useful? There's a larger point, though. As I wrote last month, too many major technology companies seem to be moving away from R&D and innovation, instead spending huge sums on fighting the patent wars or swallowing up little competitors at preposterous valuations. Google spent $12. 5 billion to buy Motorola Mobility for its patent portfolio, and Facebook forked over $1 billion to buy Instagram, a company with no revenue, no business plan, and a cute little product that's little more than a bell-and-whistle take on photo-sharing sites.
Old-fashioned innovation risk-taking at work
IBM, though, took a flyer on a product that combines advances in artificial intelligence, big data, and natural language processing to invent something new. When Big Blue started the project, "we'd be hard-pressed to know if it could be monetized," says Stephen Gold, who heads Watson Solutions. To me, that's what innovation is all about: taking a risk and exploring the leading edges of technology.
Gold did not care to say how much IBM spent developing Watson. The project, which came out of the company lab in Hawthorne, N.Y., took the services of 25 doctorate-level researchers and four labs, so it wasn't cheap. But I'm willing to bet it cost a lot less than the $1 billion shelled out for Instagram.
Did I drink a glass of Big Blue Kool-Aid during my meeting with Gold at San Francisco's Palace Hotel this week? I don't think so. If you look at the first real-world applications of Watson, you'll notice they're aimed at solving significant problems. Indeed, Watson may wind up saving lives -- and, oh yes, make money for IBM and its shareholders.
Watson's $2.7 billion payoff
Suppose you're a doctor or a nurse practitioner and a patient calls requesting an appointment, complaining of a number of odd symptoms. When he comes in, you might have to order a variety of expensive tests and do a fair amount of research to figure out what's going on with him. Now suppose you could take the patient's history and unstructured data from earlier appointments (notes written on a tablet, for example), then comb through millions of articles from medical journals and textbooks to get to the bottom of the issue. That's exactly what WellPoint, an enormous health benefits company, is doing in a pilot project using Watson.
The potential benefits are obvious: quicker, more accurate diagnoses and fewer unnecessary expensive tests. Starting soon is a partnership with Sloan-Kettering, a leading cancer research institute, to study various forms of cancer with Watson's help, first with lung cancer, then moving on to breast and prostate cancer.
Gold says that Watson is currently "learning" about oncology and is being trained to answer questions about it, in much the same way it was trained for the "Jeopardy" challenge. An Associated Press report on the IBM/Sloan-Kettering partnership put it this way: "Watson will be fed textbooks, medical journals and -- with permission -- individual medical records. Then it will be tested with more and more complicated cancer scenarios and assessed with the help of an advisory panel."
As you may have noticed in the "Jeopardy" events, Watson generally doesn't give definitive answers. Instead, it calculates a probability that an answer is correct, an important distinction in the world of medical research.
A third pilot program was announced in March: Citigroup will use Watson to study ways to improve customer service. Citigroup hopes that Watson's content analysis and evidence-based learning abilities can improve customer transactions and simplify the overall banking services. No, that's not curing cancer. But landing Citigroup as a client is an important step in proving that Watson can be a moneymaker.
How much money Watson can generate still remains to be seen, of course. But in a research note late last year, CLSA analyst Ed Maguire estimated that Watson may generate $2.7 billion in revenue in 2015, adding 52 cents of earnings per share. The technology is so new that IBM is still looking at a variety of pricing models. It will likely be related to results Watson achieves, Gold says.
IBM is not the juggernaut it once was, nor is it quite the paradise for researchers it used to be. But a company that can still spend some $6 billion a year on R&D and embark on what Gold calls "a grand challenge" every decade is a light-year ahead of companies pouring money down the rat holes of useless litigation and frivolous acquisitions.
