China Leading Race to Make Clean Energy

Shiho Fukada for The New York Times

As China takes the lead on wind turbines, above, and solar panels, President Obama is calling for American industry to step up.

TIANJIN, China — China vaulted past competitors in Denmark, Germany, Spain and the United States last year to become the world’s largest maker of wind turbines, and is poised to expand even further this year.

China has also leapfrogged the West in the last two years to emerge as the world’s largest manufacturer of solar panels. And the country is pushing equally hard to build nuclear reactors and the most efficient types of coal power plants.

These efforts to dominate the global manufacture of renewable energy technologies raise the prospect that the West may someday trade its dependence on oil from the Mideast for a reliance on solar panels, wind turbines and other gear manufactured in China.

“Most of the energy equipment will carry a brass plate, ‘Made in China,’ ” said K. K. Chan, the chief executive of Nature Elements Capital, a private equity fund in Beijing that focuses on renewable energy.

President Obama, in his State of the Union speech last week, sounded an alarm that the United States was falling behind other countries, especially China, on energy. “I do not accept a future where the jobs and industries of tomorrow take root beyond our borders — and I know you don’t either,” he told Congress.

The United States and other countries are offering incentives to develop their own renewable energy industries, and Mr. Obama called for redoubling American efforts. Yet many Western and Chinese executives expect China to prevail in the energy-technology race.

Multinational corporations are responding to the rapid growth of China’s market by building big, state-of-the-art factories in China. Vestas of Denmark has just erected the world’s biggest wind turbine manufacturing complex here in northeastern China, and transferred the technology to build the latest electronic controls and generators.

“You have to move fast with the market,” said Jens Tommerup, the president of Vestas China. “Nobody has ever seen such fast development in a wind market.”

Renewable energy industries here are adding jobs rapidly, reaching 1.12 million in 2008 and climbing by 100,000 a year, according to the government-backed Chinese Renewable Energy Industries Association.

Yet renewable energy may be doing more for China’s economy than for the environment. Total power generation in China is on track to pass the United States in 2012 — and most of the added capacity will still be from coal.

China intends for wind, solar and biomass energy to represent 8 percent of its electricity generation capacity by 2020. That compares with less than 4 percent now in China and the United States. Coal will still represent two-thirds of China’s capacity in 2020, and nuclear and hydropower most of the rest.

As China seeks to dominate energy-equipment exports, it has the advantage of being the world’s largest market for power equipment. The government spends heavily to upgrade the electricity grid, committing $45 billion in 2009 alone. State-owned banks provide generous financing.

China’s top leaders are intensely focused on energy policy: on Wednesday, the government announced the creation of a National Energy Commission composed of cabinet ministers as a “superministry” led by Prime Minister Wen Jiabao himself.

Regulators have set mandates for power generation companies to use more renewable energy. Generous subsidies for consumers to install their own solar panels or solar water heaters have produced flurries of activity on rooftops across China.

China’s biggest advantage may be its domestic demand for electricity, rising 15 percent a year. To meet demand in the coming decade, according to statistics from the International Energy Agency, China will need to add nearly nine times as much electricity generation capacity as the United States will.

So while Americans are used to thinking of themselves as having the world’s largest market in many industries, China’s market for power equipment dwarfs that of the United States, even though the American market is more mature. That means Chinese producers enjoy enormous efficiencies from large-scale production.

In the United States, power companies frequently face a choice between buying renewable energy equipment or continuing to operate fossil-fuel-fired power plants that have already been built and paid for. In China, power companies have to buy lots of new equipment anyway, and alternative energy, particularly wind and nuclear, is increasingly priced competitively.

Interest rates as low as 2 percent for bank loans — the result of a savings rate of 40 percent and a government policy of steering loans to renewable energy — have also made a big difference.

As in many other industries, China’s low labor costs are an advantage in energy. Although Chinese wages have risen sharply in the last five years, Vestas still pays assembly line workers here only $4,100 a year.

Google hits back at book critics


Google hits back at book critics
Computer screen in the New York Library
Google's digital library plans have met with strong opposition.


Google co-founder Sergey Brin has hit out at critics of the company's plans to create what could be the world's largest virtual library.

Writing in the New York Times, Mr Brin said he wanted to "dispel some myths" surrounding the project.

He said the plan would make millions of "out-of-print" books available to the public online.

Those against the idea fear it would give Google a monopoly over access to the world's information.

"In reality, nothing in this agreement precludes any other company or organisation from pursuing their own similar effort," he wrote.

"The agreement limits consumer choice in out-of-print books about as much as it limits consumer choice in unicorns.

"Today, if you want to access a typical out-of-print book, you have only one choice — fly to one of a handful of leading libraries in the country and hope to find it in the stacks."

'No deal'

Google Books - formerly known as Google print - was first launched in 2004.

Lauryn Hill Zion



Lyrics
Unsure of what the balance held
I touched my belly overwhelmed
By what I had been chosen to perform
But then an angel came one day
Told me to kneel down and pray
For unto me a man child would be born
Woe this crazy circumstance
I knew his life deserved a chance
But everybody told me to be smart
Look at your career they said,
"Lauryn, baby use your head"
But instead I chose to use my heart

Now the joy of my world is in Zion
Now the joy of my world is in Zion

How beautiful if nothing more
Than to wait at Zion's door
I've never been in love like this before
Now let me pray to keep you from
The perils that will surely come
See life for you my prince has just begun
And I thank you for choosing me
To come through unto life to be
A beautiful reflection of his grace
See I know that a gift so great
Is only one God could create
And I'm reminded every time I see your face

That the joy of my world is in Zion
Now the joy of my world is in Zion
Now the joy of my world is in Zion
Now the joy of my world is in Zion

Marching, marching, marching to Zion
Marching, marching
Marching, marching, marching to Zion
Beautiful, beautiful Zion

Students 'could face dope tests'

Students 'could face dope tests'

By Angela Harrison
BBC News education reporter

degree certificate
American studies have measured such drug use

Students could one day face dope tests to prove they have not boosted their academic performance with so called "smart drugs", a psychologist suggests.

More students are turning to drugs in an attempt to boost their grades, writes Vince Cakic of Sydney University in the Journal of Medical Ethics.

Among drugs apparently being used are those designed to treat hyperactivity and dementia.

Some academics think their use can be a positive thing, if regulated.

There are calls for a debate.

They say that although much written about the extent of drug use in the UK is anecdotal, studies at American universities suggest as many as one in four students on some campuses are taking stimulants.

Mr Cakic said: "The possibility of purchasing 'smartness in a bottle' is likely to have broad appeal to students seeking to gain an advantage in an increasingly competitive world."
The drugs would be near impossible to ban, he said.

"As laughable as it may seem, it is possible that scenarios such as this [urine testing] could very well come to fruition in the future.

Any attempt to prohibit the use of [smart drugs] will probably be difficult or inordinately expensive to police effectively
Vince Cakic, Sydney University
"However, given that the benefits of [smart drugs] could also be derived from periods of study at any time leading up to examinations, this would also require drug testing during non-exam periods," he writes.

"If the current situation in competitive sport is anything to go by, any attempt to prohibit the use ... will probably be difficult or inordinately expensive to police effectively," he warns.
Experts working in the UK are divided on the issue between those who believe such drugs, if taken under supervision, are a legitimate way of boosting performance and those who warn of the health and social dangers of such use.

'Own choices'
John Harris, Professor of Bioethics at Manchester University, said: "My position on enhancement generally and on 'smart drugs' in particular is that enhancement is definitely a good thing.

"If they do improve function in a way that is safe enough I think people should make their own choices about whether to access them.

"Drugs are banned by most sports governing bodies, so if athletes use them it is only cheating because it is against the rules.

"In education, there are lots of ways students can steal an advantage over others: they could be privately educated, have extra tuition, have access to expensive study aids or expensive computers.

"All of these, if others do not have access to them, are in a sense unfair but there are good reasons for students to improve their study skills."

We have a number of well-respected scientists speaking in very positive terms.....but among teachers, there are concerns
Paul Howard-Jones, Bristol University
Professor Harris believes the sector should be regulated but that use of the so-called "smart drugs" should not be banned.
"There is a lot of evidence that there is a wide black market in these drugs.

"They are available on prescription and on the internet. it would be better if they were regulated so people could have access to these drugs, with their GPs keeping track of them."

Universities as a whole warn students of the health risks with taking drugs not prescribed for them.

A spokeswoman for Universities UK said: "Currently, much of the evidence available on the use of [smart] drugs among students is largely anecdotal.

"However, universities take the issue of drug abuse very seriously, and would have grave concerns about students taking drugs not prescribed to them. Not only is this illegal but it also poses health risks to those students.

"All universities would advise students under pressure to seek advice from university counselling services, welfare officers or their GP."

Dr Ken Checinski, a specialist in addictive behaviour and psychological medicine at St George's, University of London, has treated many young people who have taken such drugs to boost their exam performance.
One was 15.

He says such drugs are marketed as making people cleverer and braver - but says the reality can be the opposite.

"I obviously see the extreme cases," he said, "but people can develop severe anxiety from amphetamines, they make the heart beat fast and can fuel panic attacks, so people feel like they are having a heart attack which is very frightening.

"They can suffer sleeplessness and this can be very long-lasting; and they might have mood disorder not quite as bad as the crash from coming off cocaine but a near crash. They might feel suicidal."

In the most extreme cases, Dr Checinski said people could develop psychosis and have delusions or hear voices.

Educational view
Dr Paul Howard-Jones, senior lecturer at Bristol University's graduate school of education, says it is vital that the issues are debated now, before such drug use becomes more common.
"We need to have a debate on this now. These drugs will multiply in number, range and power," he said.

"We have a number of well-respected scientists speaking in very positive terms about these drugs in terms of benefits for us as a society and as individuals, but among teachers, there are concerns.

"I can see there are potential huge benefits but they challenge many of the values we have in education and society."

Dr Howard-Jones said possible concerns were about the devaluing of normal achievement and effort, inequalities - because not everyone might be able to afford the drugs - and the possibility of students feeling pressured to use them.

Teachers he had surveyed mostly thought these drugs would increase the education poverty gap, would demand drug testing if they became prevalent, and would not value grades achieved using them as highly as those achieved without drugs.

The calls for debate and continued research are also reflected in the article by Vince Cakic, from Sydney University.

"Perhaps the most that can be hoped for is to have a better understanding of the dangers of (the drugs) so that students will take this into consideration when deciding whether or not to use them," he said.Share/Save/Bookmark

Mighty microbes might help clean up oil extraction and radioactive wastes

magnified e. coliThere appears to be literally nothing microbes cannot do. From the invention of photosynthesis to lifecycles that require no sunlight—even surviving extreme radiation—the most extreme microbes thrive almost everywhere scientists look. And now microbiologists have added two more energy-related tricks to the microbial arsenal.

At the European Society for General Microbiology meeting this week, Richard Johnson and his fellow scientists from the University of Essex will present research showing that a mixed ecosystem of particular bacteria can survive—and clean up—one of the most lethal man-made environments: the residue from extracting petroleum from oil sands.

Extracting this heavy oil and refining it produces a slew of toxic waste, particularly water with naphthenic acid (one of the secret ingredients of napalm). In Athabasca region of Canada—home to much of the oil sands industry—there are at least one billion cubic meters of such polluted water sitting in local ponds.

What to do? Unleash bacteria, Johnson says. The microbes can break down the naphthenic acid into more benign byproducts in a few days rather than the decade or more it can take naturally. This can cut down on the environmental impact of producing oil from tar sands, of which there is an estimated 3.6 trillion barrels (double known conventional oil reserves).

It does not, however, address that other related byproduct: climate change caused by the greenhouse gases emitted when the oil is burned. Maybe microbes can help with that too (after all, they were responsible for the composition of the atmosphere until humans came along).

And it turns out E. coli—most famous for its role in food poisoning—does a pretty good job of cleaning up another potentially important but lethal energy source: radioactive waste. Lynne Macaskie and colleagues at the University of Birmingham show in another presentation at the same meeting how said E. coli, in conjunction with a cheap, widely available chemical (inositol phosphate), can recover uranium from the polluted waters of mines.

Basically, the E. coli break down the chemical and free the phosphate, which then bonds with the uranium and forms a precipitate on the exterior of the cell that can be harvested.

The researchers estimate that such recovered uranium would cost about 15 cents per gram of the nuclear fuel element. But it also offers an environmental protection advantage, removing radioactive material from the mine tailings. The process could even be used on spent fuel rods and other nuclear waste.

"Space Internet" to Link Worlds by 2011?

Brian Handwerk
for National Geographic News
July 9, 2009

For all its might, the World Wide Web is still limited to, well, our world.

But that's quickly changing with the advent of an "interplanetary internet" that planners say will revolutionize space communication.


The Disruption Tolerant Networking (DTN) system, which entered another phase of testing this week, will allow astronauts to Google from the moon or tweet their observations from space.

But DTN provides far more than a connection to check your email. It's also essential for simplifying space command and control functions—such as power production or life-support systems—crucial for future space initiatives.


(Related: "'Rocket NASCAR,' Moon Base Part of 50-Year Space Vision.")

"You need an automated communications technology … to sustain planetary exploration on the scale that NASA and others want to perform over the next decade," said Kevin Gifford, a senior research associate at BioServe Space Technologies at the University of Colorado, Boulder.

"DTN enables the transition from a simple point-to-point network, like a walkie-talkie, to a true multimode network like the Internet."


After a decade of development DTN has advanced quickly over the past year, and NASA missions are planning to adopt the network by 2011. In November 2008 NASA test-drove the network by sending space images to and from the EPOXI spacecraft, some 20 million miles (32 million kilometers) from Earth.

DTN protocols were also installed on the International Space Station in May, and summer testing began the first week of July.


Houston, We're Fixing a Problem

Though tweeting astronauts have gotten a lot of press, "the reality is that they [don't really] tweet or have browsing capability on the International Space Station," explained Gifford, who is part of a large, cooperative DTN effort that has also included NASA and Internet veterans.

"Right now they actually voice down a simple blurb, and the tweet is operated manually from Houston," he said. In fact most current space communication involves humans manually scheduling each and every link, sometimes weeks or even months in advance for distant spacecraft, and dictating exactly which data are sent and when.


"Typically spacecraft go off and do their thing, gather up data, and then on some schedule they connect to the ground and [we] pull down the results of what it has been doing and send up instructions for the next time period," Hooke said.

Such manual operations are inefficient and expensive. But simply extending Earth's Internet into space won't work.

The Web uses Transmission-Control Protocol/Internet Protocol (TCP/IP), a type of communication language in which hosts and computers must be constantly connected.

This rarely happens in space, where intermittent connections are the norm because of the vast distances involved and the tendency of orbiting moons, rotating planets, and drifting satellites to temporarily disrupt wireless lines of communication.


Communications Leap

Typical space delays, even those caused by solar storms, are handled in stride by DTN, Hooke said.


Each node in the network—whether it's the International Space Station or a small orbiting robot—stores all the data it receives until a clear opportunity arises to pass its "bundle" along to the others in the network. DTN nodes do not discard data when a destination path can't be identified.


Hooke likens this "store and forward" process to a basketball team systematically passing the ball downcourt to players closer to the hoop.

The result, he explained, will be a communications leap akin to that between the post office and the telephone.


"A letter is a pretty self-contained story, it says do this or order that, and you mail it off and wait for a response."


But the new DTN system will open a more consistent line of back-and-forth communication.

(Read about how humans are exploring the cosmos.)


Edge of the Solar System

DTN is already used for earthbound projects.

Scientists, for instance, are using the system to tag and track wildlife with a data-delivery capacity far more reliable than past satellite-based networks.


DTN can also bring broadband Web to remote areas with few communication structures, connecting remote humans such as the Arctic's Sami people via satellite with far shorter time lags.

The U.S. military has also embraced the technology to help keep lines of communication open in remote areas—or when other infrastructure is destroyed.


So far, DTN doesn't seem to have a catch, experts say.

"There are no physical limits on where the protocols would stop working," Hooke said.

"We could use it to [send messages to] the edges of the solar system—the question is, how long will you wait for a response?"
