China builds an ‘artificial sun’ that is 6 times hotter than our ‘natural sun’

China builds an ‘artificial sun’ that can hit temperatures of 100 million degrees Celsius

Last month, we had reported that a team of scientists at the Chengdu Aerospace Science and Technology Microelectronics System Research Institute Co (CASC) in China has developed an “artificial moon”, 8 times brighter than the natural moon to replace streetlights in the country by 2020.

Now, a team at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences announced that its Experimental Advanced Superconducting Tokamak (EAST) reactor, has hit a new temperature of reaching 100 million degrees Celsius.

The EAST has been dubbed as “artificial sun” since it replicates the process used by the sun to produce energy. It burns at 100 million degrees Celsius, which is over six times hotter than the core of the sun. The temperature of the real sun’s core is at around 15 million degrees Celsius. The state-of-the-art reactor is designed to turn hydrogen into cost-effective green energy.

“Scientists carried out the experiments on plasma equilibrium and instability, confinement and transport, plasma-wall interaction and energetic particle physics to demonstrate the long time scale steady-state H-mode operation with good control of impurity, core/edge MHD stability, heat exhaust using an ITER-like tungsten divertor,” the institute wrote in its announcement article.

Our sun generates light and heat energy by a process called nuclear fusion when two hydrogen nuclei combine to produce huge amount of energy. Scientists believe that nuclear fusion occurs at 100 million degrees Celsius. However, since these two hydrogen nuclei normally resist each other, it requires vast temperatures to overcome their opposing forces.

Hence, reaching over 100 million degrees Celsius is an important step as this is the minimum temperature required to create conditions that are suitable for nuclear fusion on Earth.

The aim of the EAST is to comprehend nuclear fusion process before building a full reactor and use it as an alternative source of energy on Earth in the future. The process promises more power and is far safer than fission, producing almost no dangerous nuclear waste.

“Nuclear fusion is arguably the best way for human beings to get energy. In terms of raw materials, deuterium and tritium required for nuclear fusion are almost inexhaustible in the ocean. Besides, nuclear fusion does not produce any radioactive waste, so it is extremely environmentally friendly,” said the researchers in a recently issued statement.

Matthew Hole, an Associate professor from the Australian National University told ABC News that the achievement was an important step for nuclear fusion science and could be the solution to global energy problems.

“It’s certainly a significant step for China’s nuclear fusion program and an important development for the whole world,” Dr. Hole said.

“The benefit is simple in that it is very large-scale baseload [continuous] energy production, with zero greenhouse gas emissions and no long-life radioactive waste.

The research group in charge of EAST say it accomplished this milestone through the use of various new methods in heating and controlling the plasma; however, they were able to maintain the record temperature for just around 10 seconds.

Dr. Hole also adds that the nuclear fusion reactors evade the risks related to the current nuclear fission reactors, which can be modified into dangerous weapons and are susceptible to possible meltdowns with catastrophic outcomes.

The artificial sun was designed and built by China back in 2006. EAST is 11 meters tall, has an 8 meters diameter and weighs 400 tons. According to China Daily, China becomes the first country to design and develop such an equipment on its own.

Science is Getting Less Bang for Its Buck

Despite vast increases in the time and money spent on research, progress is barely keeping pace with the past. What went wrong? An anonymous reader shares a report: Today, there are more scientists, more funding for science, and more scientific papers published than ever before. On the surface, this is encouraging. But for all this increase in effort, are we getting a proportional increase in our scientific understanding? Or are we investing vastly more merely to sustain (or even see a decline in) the rate of scientific progress? It's surprisingly difficult to measure scientific progress in meaningful ways. Part of the trouble is that it's hard to accurately evaluate how important any given scientific discovery is. [...] With that in mind, we ran a survey asking scientists to compare Nobel prizewinning discoveries in their fields. We then used those rankings to determine how scientists think the quality of Nobel prizewinning discoveries has changed over the decades. As a sample survey question, we might ask a physicist which was a more important contribution to scientific understanding: the discovery of the neutron (the particle that makes up roughly half the ordinary matter in the universe) or the discovery of the cosmic microwave background radiation (the afterglow of the Big Bang). Think of the survey as a round-robin tournament, competitively matching discoveries against one another, with expert scientists judging which is better. For the physics prize, we surveyed 93 physicists from the world's top academic physics departments (according to the Shanghai Rankings of World Universities), and they judged 1,370 pairs of discoveries. [...] The first decade has a poor showing. In that decade, the Nobel Committee was still figuring out exactly what the prize was for. There was, for instance, a prize for a better way of illuminating lighthouses and buoys at sea. That's good news if you're on a ship, but scored poorly with modern physicists. But by the 1910s the prizes were mostly awarded for things that accord with the modern conception of physics. A golden age of physics followed, from the 1910s through the 1930s. [...] Our graph stops at the end of the 1980s. The reason is that, in recent years, the Nobel Committee has preferred to award prizes for work done in the 1980s and 1970s. In fact, just three discoveries made since 1990 have yet been awarded Nobel Prizes. This is too few to get a good quality estimate for the 1990s, and so we didn't survey those prizes. However, the paucity of prizes since 1990 is itself suggestive. The 1990s and 2000s have the dubious distinction of being the decades over which the Nobel Committee has most strongly preferred to skip back and award prizes for earlier work. Given that the 1980s and 1970s themselves don't look so good, that's bad news for physics.

Kilogram Gets a New Definition

Scientists have changed the way the kilogram is defined. Currently, it is defined by the weight of a platinum-based ingot called "Le Grand K" which is locked away in a safe in Paris. On Friday, researchers meeting in Versailles voted to get rid of it in favour of defining a kilogram in terms of an electric current. From a report: The decision was made at the General Conference on Weights and Measures. But some scientists, such as Perdi Williams at the National Physical Laboratory in the UK, have expressed mixed feelings about the change. "I haven't been on this project for too long but I feel a weird attachment to the kilogram," she said. "I think it is such an exciting thing and this is a really big moment. So I'm a little bit sad about [the change]. But it is an important step forward and so the new system is going to work a lot better. It is also a really exciting time, and I can't wait for it to happen." Le Grand K has been at the forefront of the international system of measuring weights since 1889. Several close replicas were made and distributed around the globe. But the master kilogram and its copies were seen to change -- ever so slightly -- as they deteriorated. In a world where accurate measurement is now critical in many areas, such as in drug development, nanotechnology and precision engineering -- those responsible for maintaining the international system had no option but to move beyond Le Grand K to a more robust definition.
