China’s independently developed HXD1C electric locomotive for high-altitude operations recently passed a ground-based automatic phase separation test on the Xining-Golmud section of the Qinghai-Tibet Railway.

Ground-based automatic phase separation technology is the best choice for ensuring safe, accurate, and efficient transportation on heavily loaded high-altitude electrified railways. It is based on various advanced applied technologies in the fields of high-voltage electric equipment, automation, and synchronous closing.

The test was jointly carried out by the Department of Science and Technology and the Department of Transportation under the Ministry of Railways, the Qinghai-Tibet Railway Company, and China Academy of Railway Sciences.

The HXD1C locomotive’s system monitoring, high- and low-voltage electric equipment insulation, and other technologies are suitable for the Qinghai-Tibet Plateau, ensuring enough traction, automatic phase separation, and safe and reliable operations of the traction power supply system.

It is the world’s first ground-based automatic phase separation test in high-altitude areas, marking China has mastered the technology for manufacturing compatible alternating current (AC) electric locomotives.

very plausible, don't forget that low altitude airspace wasn't even opened up to civilians until recently. Plus the cost of a helicopter is still very high. In the states, you just have to be somewhat rich to have a cheap helicopter or cheap aeroplane, but the cost compare to average income in China, you have to be mega rich to afford it. Plus, there's not that many hobbyist in China of this field, there's no cultural or historical sedimentation of civilian aviation in China. But I'm sure, as wealth level increases, civil helicopters will become hotter and hotter in China.

So in China, Police helicopter is not considered civilian ?

So in China, Police helicopter is not considered civilian ?

Beijing police force do not have their own helicopter until mid 1990s, that's the fact.

Even today, unless something as "big shot" as Olympic Games or World Expo, you don't really see helicopters flying around enven at tier 1 city like Beijing, Shanghai...

China's infrastructure is dirt poor as late as most recent 20 years, so understandably, China's infrastructure build up efforts dwarfs the rest of the known world in the recent 20 years.

A helicopter has hovered over the Tongbai Mountain in Nanyang city, Henan province for several days, dragging a 45-meter long cable and a coil of five meters in diameter, which attracted many people.

According to sources, it is the towed bird helicopter airborne electromagnetic prospecting system developed by the National High-tech Research and Development Program of China, also called National 863 Program, prospecting mineral resources.

Chen Bin, senior engineer of China Aero Geophysical Survey and Remote Sensing Center for Land and Resources, said that their project team finally developed the first helicopter prospecting system independently in China after four years of efforts. The helicopter can make prospection for 300 meters underground, which filled the domestic blank and reached international standards of the same prospection system. Another engineer Yu Changchun said that the system is good at prospecting copper, iron and zinc mines.

oil rigs belonging to PetroChina are seen near the banks of a snow covered lake in Daqing in northeastern
China's Heilongjiang province.


A big shift is happening in Big Oil: an American giant now ranks behind a Chinese upstart.

Exxon Mobil is no longer the world's biggest publicly traded producer of oil. For the first time, that distinction belongs to a 13-year-old Chinese company called PetroChina. The Beijing company was created by the Chinese government to secure more oil for that nation's booming economy.

PetroChina announced Thursday that it pumped 2.4 million barrels a day last year, surpassing Exxon by 100,000.
The company has grown rapidly over the last decade by squeezing more from China's aging oil fields and outspending Western companies to acquire more petroleum reserves in places like Canada, Iraq and Qatar. It's motivated by a need to lock up as much oil as possible.

The company's output increased 3.3 percent in 2011 while Exxon's fell 5 percent. Exxon's oil production also fell behind Rosneft, the Russian energy company.

PetroChina's rise highlights a fundamental difference in how the largest petroleum companies plan to supply the world as new deposits become tougher to find and more expensive to produce.

Every major oil company has aggressively pursued new finds to replace their current wells. But analysts say Western oil firms like Exxon Mobil have been more conservative than the Chinese, mindful of their bottom line and investor returns. With oil prices up 19 percent in 2011, they still made money without increasing production.

PetroChina Co. Ltd. has a different mission. The Chinese government owns 86 percent of its stock and the nation uses nearly every drop of oil PetroChina pumps. Its appetite for gasoline and other petroleum products is projected to double between 2010 and 2035.

"There's a lot of anxiety in China about the energy question," says energy historian Dan Yergin. "It's just growing so fast."

While PetroChina sits atop other publicly traded companies in oil production, it falls well short of national oil companies like Saudi Aramco, which produces nearly 8 million barrels a day. And Exxon is still the biggest publicly traded energy company when counting combined output of oil and natural gas. PetroChina ranks third behind Exxon and BP in total output of oil and natural gas.

PetroChina is looking to build on its momentum in 2012.

"We must push ahead," PetroChina chairman Jiang Jiemin said in January.

PetroChina has grown by pumping everything it can from reserves in China, estimated to contain more than 6.5 billion barrels. It drilled thousands of oil wells across vast stretches of the nation's northern grasslands. Some of those fields are ancient by industry standards, dating close to the beginning of China's communist government in the 1950s.

The commitment to aging fields distinguishes PetroChina from its biggest Western rivals. Exxon and other major oil companies typically sell their aging, low-performing fields, or they put them out of commission.

PetroChina also has been on a buying spree, acquiring new reserves in Iraq, Australia, Africa, Qatar and Canada. Since 2010, its acquisitions have totaled $7 billion, about twice as much as Exxon, according to data provider Dealogic.

Several other Chinese companies have become deal makers around the globe as well. Total acquisitions by Chinese energy firms jumped from less than $2 billion between 2002 and 2003 to nearly $48 billion in 2009 and 2010, according to the International Energy Agency. More times than not, the companies are paying above the industry average to get those deals done.

It's making some in the West nervous.

In 2005, for example, CNOOC Ltd., a company mostly owned by the Chinese government tried to buy American oil producer Unocal. U.S. lawmakers worked to block the deal, asking President Bush to investigate the role the Chinese central government played in the process. Chevron Corp. eventually bought Unocal for $17.3 billion.

"There's a resistance to Chinese investment in (U.S.) oil and gas," Morningstar analyst Robert Bellinski says. "It's like how Japan was to us in the 1980s. People think they're going to take us over. They're going to buy all of our resources."

That's unlikely to happen. It doesn't make economic sense to export oil away from the world's largest oil consumer.

But the Chinese could make it tougher for Big Oil to generate returns for their shareholders. China's oil companies have been willing to outspend everyone and that drives up the price of fields and makes it more expensive for everyone to expand.

"You now have to outbid them," says Argus Research analyst Phil Weiss. "If you can't, you're going to have access to fewer assets."

Longer term, Chinese expansion globally will bring benefits to the U.S. and other economies. By developing as many oil wells as possible — especially in Africa, Iraq and other politically unstable regions — China will help expand supply.

"Frankly, the more risk-hungry producers there are, the more oil will be on the market, and the cheaper prices are," says Michael Levi, an energy policy expert at the Council on Foreign Relations.

Despite its swift expansion, PetroChina and other Chinese companies still have much to prove to investors, analysts say.

PetroChina's parent, China National Petroleum Corp., for example, has spent millions of dollars in Sudan to provide highways, medical facilities and shuttle buses for the elderly. Oil companies typically don't do that. All of that increases the cost of business and minimizes the returns for shareholders.

In 2009 and 2010, PetroChina's profit margins for its exploration and production business were only about two-thirds that of Exxon Mobil's. Its stock price has climbed less than 1 percent, in the past year, compared with a 3.7 percent rise in the stock of Exxon Mobil Corp.

"You have to ask yourself: What is the purpose of PetroChina?" Bellinski says. "It is to fuel China. That's it. Although they're a public company, I'm very skeptical that they have any interest in shareholder value creation."

China's Three Gorges Corp. on Thursday marked the beginning of construction for a dam that will flood the last free-flowing portion of the middle reaches of the Yangtze, the country's longest river.

The 30 billion yuan ($4.75 billion) Xiaonanhai dam is decried by environmentalists because it will flood a nature reserve designed to protect about 40 species of river fish.

Completion of the dam would turn the middle section of the Yangtze into a series of reservoirs, leaving "no space for fish", said environmentalist Ma Jun, who has been active for over two years in trying to prevent the dam.

"This is the last one, the last section in 2,000 kilometers (1,250 miles) along the Yangtze that was left for endangered or local fish species. This would be their last habitat," Ma told Reuters.

A ceremony was held to commence early-stage preparation, including building a road and laying power lines and water pipes, said Zhu Guangming, news department director at Three Gorges Corp.

"Construction of the dam itself will begin only after we get final approval," Zhu said, declining to give cost estimates.

"The government will give due consideration to all aspects including environment impact before issuing a permit."

The Xiaonanhai dam would be the last in a series of 12 dams along the Yangtze, the rest of which are all completed or under construction.

The series will stretch inland from the Three Gorges Dam, which has created an inland reservoir more than 600 km long that has allowed the city of Chongqing to develop into an inland port. When completed, Xiaonanhai dam is designed to produce 1.76 gigawatts, a fraction of the 22.50 GW that the Three Gorges Dam will produce when it reaches full capacity.

AWAITING FINAL APPROVAL

The Chongqing municipal government is currently embroiled in a power struggle after the ambitious party secretary, Bo Xilai, was sacked earlier this month. The mega-city's hard-charging police chief was also taken into custody by central authorities after spending a day in the nearest U.S. consulate.

Preliminary approval for the dam was issued by the National Development and Reform Commission, China's top planning agency, which also has the authority to issue final approval.

The boundaries of the nature reserve were earlier re-drawn to allow the construction of the even larger Xiangjiaba and Xiluodu dams.

According to NGO International Rivers, which opposes the construction of large hydro dams and has been critical of China's ambitious hydropower plans, the Xiangjiaba dam will be 6.4 GW and the Xiluodu dam 13.86 GW.

China wants to raise installed power capacity by 470 gigawatts (GW) to 1,437 GW by 2015 -- the largest in the world. At least 110 gigawatts of the new capacity will be from hydro power -- equivalent to five Three Gorges hydropower projects. Current hydropower capacity is 216 GW, also the world's largest.

The Three Gorges Dam is the world's biggest power project and was controversial well before it began construction in 1994.

Objections ranged from the destruction of rare species to the flooding of historic towns and displacement of millions of people, to concerns that it would quickly silt up and lose its efficiency in generating power.

It produces about 2 percent of China's power.

Subsequent audits of the Three Gorges project showed that many of the flooded communities were never properly resettled while the steep banks of the reservoir have been plagued by dangerous landslides as the water undermines the hillsides.

In January, China's environment ministry told hydropower developers they must "put ecology first" and pay strict attention to the impact of their projects on local rivers and communities.

Chemist Zhang Lina became the first Chinese scientist to win the Anselme Payen Award, a prestigious chemistry award, for her contributions to the science and chemical technology of cellulose and its allied products.


Zhang's daughter, Dr. Du Wenzheng, accepted the award on behalf of her mother from Alfred French, chairman of the American Chemical Society's Cellulose and Renewable Materials Division, at a ceremony held in San Diego on Tuesday.

"It is not only my personal honor but also the honor of Wuhan University. It is also a recognition of the achievements made by Chinese chemists," Zhang, who was unable to attend the ceremony due to health reasons, said, addressing the ceremony via video.

Zhang, a professor at Wuhan University in central China's Hubei province, has devoted herself to basic and applied research on biomass natural polymeric material science.

She and her team have successfully created useful materials out of agricultural waste such as bagasse, crab shells and bean dregs through polymer physics and green technologies.

Zhang, also an academician of Chinese Academy of Sciences, is the first Chinese scientist to win the annual award since it was established in 1962 to honor outstanding professional contributions to the science and chemical technology of cellulose and its allied products.

The award is named for Anselme Payen, a French chemist who first discovered cellulose.

Sinopec Group, China's biggest oil refiner by volume, said Thursday it has completed a deal to buy a 30-percent stake in the Brazilian assets of Galp Energia, a Portuguese energy company, at a cost of 5.16 billion U.S. dollars.

The completion of the acquisition will further expand Sinopec's overseas oil and gas business and give the company an additional daily output of 21,300 barrels of oil equivalent (BOE) by 2015 and 112,500 BOE per day in 2024, according to Sinopec.

Sinopec International Exploration and Production Corp., a wholly-owned auxiliary of Sinopec Group, took the latest shares released by Galp and covered the company's shareholder loans.

Galp, Portugal's largest oil association that binds stakes in 33 blocks of oil margin in Brazil, started a bidding process earlier last year, as it was looking for a partner to help finance its Brazilian projects.

Sinopec will also have board seats and representation in the company as part of the deal.
