    Actually, i was wondering why Chinese researchers would publicize such extremely sensitive data, normally such data would be considered to be of the highest level of secrecy (especially in China)?? Suspect

    Which made me question whether that data really is all that great.

    No one publicizes such stuff without intentions.

    Why publish stuff in first place that seems like an advantage for your country?

    A) Bluff, to see the reactions, money budgets location of enemies in what specific fields to exploit due that Bluff with what budgets in what fields they are trying to react to such Bluffs. The actual reasoning is debatable because all sides are well aware that no actual and factual data would be put in public in first place.

    B) To exegeratte achievement to make enemies more likely to missjudge capabilities of your military. Exegarrating would be consequence of winning time, if the enemy believes in your exaggeration of capabilities he will be less likely to confront with you, if it achieves the opposite by purposely underestimating the own capabilities so enemies react different to it. Usually such methods are used for only one thing to get more money like US boasting its Aegis class being jammed so they can get more money or like Germany as a bitch of US to get DU rounds, money, G-36 is bad more money and UCAV drones do not work properly, which is known for long time and they want more of the same garbage means even more money.

    C) It is actually all together for overall missinformation to attract and exploit western espionage to test own anti-espionage capabilities of specific institution or similiar messures.

    Chinese Fusion Test Hits A Milestone By Creating 90 Million °F For 102 Seconds

    Scientists in China were able to heat plasma to three times the temperature of the core of our sun using nuclear fusion – a temperature of 90 million °F – for an impressive 102 seconds, as they continued their search to derive energy from nuclear fusion.

    They have surpassed the nuclear fusion experimental device referred to as the Wendelstein 7-X (W7-X) stellerator developed by a team of German researchers from the Max Planck Institute that managed to heat hydrogen gas to 80 million degrees Celsius, and sustain a cloud of hydrogen plasma for a quarter of a second.

    According to a statement on the institute’s website last Wednesday, the experiment was conducted on a magnetic fusion reactor at the Institute of Physical Science in Hefei, capital of Jiangsu province.

    The experiments were carried out in a donut-shaped reactor, officially known as the Experimental Advanced Superconducting Tokamak (EAST). The reactor was able to heat a hydrogen gas – a hot ionised gas called plasma – to about 50 million Kelvins (49.999 million degrees Celsius). The interior of our sun is calculated to be around 15 million Kelvins.

    The plasma can be contained by careful control of intense magnetic fields in a tight ring by running through the center of the donut’s circular cross section. In other words, the walls of the structure are never directly exposed to the high temperatures of the plasma.

    For the long term goal of such fusion reactors, it is very necessary to make sure that those temperatures can be sustained for long period of time, as a huge input of energy is required to get them started. But, if they end up stopping too soon, the reaction is net negative in energy terms. Such high energies cause great instabilities making it difficult to confine them, as controlling such intense heat is tough. Therefore, it is a positive step indeed for running an experiment at such temperatures for 102 seconds.

    It’s not the hottest temperature ever created on Earth. So far, the hottest temperature to have been created artificially in the lab remains that reached by the gargantuan Large Hadron Collider (LHC) at CERN, which managed to achieve temperatures of 4 trillion degrees Celsius back in 2012. However, those conditions last for the sheer flicker of time, which is inadequate for creating energy.

    The ultimate goal of China’s team is to hit 100 million degrees Celsius now, and sustain the resulting hydrogen plasma for over 1,000 seconds, or 17 minutes. In the meantime, now that their ‘proof of concept’ experiment is out of the way, the German team says it could possibly sustain its plasma for as long as 30 minutes.

    However, most scientists who are in agreement advocate that the long-yet-intense burn required for fusion needs to be around 180 million °F, which means we are likely decades away from actually connecting nuclear fusion to solve humanity’s energy problems.

    WOW... that is amazing for people who believe anything and don't think for themselves...

    90 million degrees Fahrenheit is about 50 million degrees Celcius... 102 seconds is impressive compared with a quarter of a second, but 80 million degrees C is equal to 144 million degrees F... perhaps if they dropped the temperature they could also do it for a much longer period too.

    China electromagnetic launch technology eligible for lethal revolutionary breakthrough


    CHINA IS MAKING RAILGUNS TOO

    The second batch of Chinese Type 055 destroyers will likely feature railguns, starting in the 2020-2025 timeframe. A 32 megajoule railgun on the Type 055 destroyer would be able to launch a ten kilogram projectile over a 100 nautical miles away, with the impact energy of medium artillery. Railgun ammunition can be guided, and programmed to explode over a target, destroying soft targets like parked aircraft and missile launchers.

    World’s largest radio telescope put into use in China

    The telescope, nicknamed Tianyan, or the Eye of Heaven, can accurately image twice as much the sky as the Arecibo Observatory in Puerto Rico



    BEIJING, September 26. /TASS/. The world's largest radio telescope was put into use on Sunday in a mountainous region of southwest China's Guizhou Province, Xinhua reported on Sunday.

    "Shortly after noon, in a karst valley in Pingtang County, hundreds of astronomers and astronomy enthusiasts witnessed the official launch of the Five-hundred-meter Aperture Spherical Telescope's (FAST) mission to explore space and hunt for extraterrestrial life.

    "Work on the nearly 1.2-billion-yuan ($180 million) project started in 2011, 17 years after it was proposed by Chinese astronomers.

    "The installation of the telescope's main structure a 4,450-panel reflector as large as 30 football pitches was finished in early July," the agency wrote.

    "The telescope, nicknamed Tianyan, or the Eye of Heaven, can accurately image twice as much the sky as the Arecibo Observatory in Puerto Rico, which had previously been the world's largest single-dish radio telescope, with double sensitivity and five to 10 times the surveying speed."

    "(The telescope) will certainly generate enthusiasm, bring people into science, and make China important in the world of science," Joseph Taylor, a Nobel Prize-winning astronomer at Princeton University, told Xinhua.

    "The astronomer was awarded the Nobel Prize in physics in 1993 for discovering indirect proof of gravitational waves with the assistance of Puerto Rico's Arecibo Observatory, home to a radio telescope that is 350 meters in diameter.

    Taylor expects FAST to be a "productive" project, even if he is unsure whether any of its discoveries will lead to a Nobel Prize.

    In fact, FAST has already had a good start. In a recent trial observation, it received a set of high-quality electromagnetic waves sent from a pulsar about 1,351 light-years away, the agency reported referring to Qian Lei, an associate researcher with the National Astronomical Observation (NAO) under the Chinese Academy of Sciences, which built the project.

    FAST's tasks include observation of pulsars as well as exploration of interstellar molecules and interstellar communication signals.

    To ensure the telescope's performance, more than 8,000 locals are being resettled from their homes to make way for the project, which requires radio silence within a 5-kilometer radius. Visitors to the zone must turn off their mobile phones.

    The telescope's leading engineer Wang Qiming said the telescope, designed and built by Chinese scientists, will remain the global leader for the next 10 to 20 years.

    Yan Jun, head of the NAO, said China will roll out more "world-class" telescope projects in five to 10 years.

    Chinese scientists have developed a small, powerful and secure radar system that relies on quantum physics to detect stealth targets located up to 100 kilometers (62 miles) away, China Electronics Technology Group Corporation (CETC) announced.

    CETC described the device as the first "single-photon quantum radar system" in the country that uses entangled photons to detect objects that remain invisible to existing systems.

    If true, this will come as bad news for the Pentagon which has heavily invested in stealth as the key game-changing technology in defense. The DoD's latest procurements include the costly Lockheed Martin F-35 Lightning II stealth multirole fighter and the USS Zumwalt (DDG-1000) guided missile destroyer that also has stealth capabilities.

    The CETC radar utilizes a physical phenomenon known as quantum entanglement. Albert Einstein famously derided quantum entanglement as a "spooky action at a distance," but later research showed that the concept was indeed feasible. This is how it works. A quantum radar generates pairs of entangled photons, sending one particle into the air. This enables the system to obtain "critical information about a target, including its shape, location, speed, temperature and even the chemical composition of its paint from returning photons," Stephen Chen explained.

    In theory, a quantum radar needs only one returning photon to determine an object's composition, the direction it is headed and its speed. This might sound like something from a science fiction novel, but the radar, according to CETC, has already been tested. The system intercepted targets located 100 kilometers away during a recent field trial, but some say that the maximum range could be greater. "The figure in declassified documents is usually a tuned-down version of the real [performance]," Professor Ma Xiaosong, a physicist at Nanjing University, told South China Morning Post. "The announcement has gone viral [in the radar research community]."

    The new system, according to CETC, has additional advantages, including small size and resilience to countermeasures. CETC designs and manufactures advanced electronics and communication equipment, information systems, software and components for military and civilian purposes.

    The state-owned company comprises research institutions behind some of the major technological breakthroughs in the country. They are said to have developed electronics for China's first nuclear bomb, guided missile and geo-orbital satellite.
