Kína kveikir á kjarnorkuknúinni, sól tíu sinnum heitari en sjálf sólin. Þetta er samruna orka svipað og er notað í vetnissprengjunni og er 1000 sinnum aflmeiri en kjarnorkusprengjan, sem er sundrunar orka.

Peking hefur með góðum árangri virkjað „gervisól“ kjarnabræðsluofn sinn í fyrsta skipti, að því er People’s Daily greindi frá á föstudag.

 

Það er hannað til að vera hreinn orkugjafi, svipaður raunverulegri sól.
HL-2M Tokamak hvarfaflinn er gerður til að endurtaka náttúruleg viðbrögð sem eiga sér stað í sólinni með vetni og deuterium lofttegundum sem eldsneyti og er stærsta og fullkomnasta tilraunakönnunartæki Kína.

Það er staðsett í suðvesturhluta Sichuan héraðs og lauk því seint á síðasta ári. Kjarnaofninn er oft kallaður „gervisól“ vegna gífurlegs hita og afls sem hann framleiðir.

 

Beijing has successfully powered up its “artificial sun” nuclear fusion reactor for the first time, China’s People’s Daily reported on Friday. It’s designed to be a clean energy source, similar to the real Sun.

Made to replicate the natural reactions that occur in the sun using hydrogen and deuterium gases as fuels, the HL-2M Tokamak reactor is China's largest and most advanced nuclear fusion experimental research device. 

It is located in southwestern Sichuan province and was completed late last year. The reactor is often called an "artificial sun" due to the enormous heat and power it produces.

The HL-2M Tokamak uses a powerful magnetic field to fuse hot plasma and can reach temperatures of over 150 million degrees Celsius, approximately ten times hotter than the core of the Sun.

“The development of nuclear fusion energy is not only a way to solve China’s strategic energy needs, but also has great significance for the future sustainable development of China's energy and national economy,” the People’s Daily reported. 

The project is part of China’s involvement with the International Thermonuclear Experimental Reactor (ITER), based in France.

The ITER is the world’s largest nuclear fusion project with a price tag of about €20 billion ($24 billion). It involves 35 countries and is expected to be completed in 2025.

Chinese scientists have been working on developing smaller versions of the nuclear ‎samruni‎ reactor, including the HL-2M Tokamak, since 2006.

Fusion is considered the Holy Grail of energy and is what powers the Sun, but achieving fusion is both extremely difficult and prohibitively expensive. 

By harnessing the power produced through nuclear fusion it is possible to tap into almost limitless clean energy. Researchers around the world have been trying to attain that goal for decades. The main issue has been finding an affordable way to contain piping hot plasma in one space and keeping it stable enough for fusion to occur.

Skilar tækið meiri orku af sér en þarf til að knýja það? Því annars er þetta ekki orkuframleiðsla heldur eyðsla (sem á þó e.t.v. rétt á sér í tilraunaskyni).

Experimental Advanced Superconducting Tokamak (EAST) frá hina, sem líkir eftir orkuöflunarferli sólarinnar, setti nýtt met eftir að það hljóp í 216 milljón gráður Fahrenheit (120 milljón gráður á Celsíus) í 101 sekúndu samkvæmt ríkisfjölmiðli. Í 20 sekúndur til viðbótar náði „gervisólin“ einnig hámarkshita sem var 288 milljónir gráður á Fahrenheit (160 milljónir gráður á Celsíus), sem er yfir tífalt heitara en sólin.

China’s Experimental Advanced Superconducting Tokamak (EAST), which mimics the energy generation process of the sun, set a new record after it ran at 216 million degrees Fahrenheit (120 million degrees Celsius) for 101 seconds, according to state media. For another 20 seconds, the “artificial sun” also achieved a peak temperature of 288 million degrees Fahrenheit (160 million degrees Celsius), which is over ten times hotter than the sun.

Þetta svarar ekki spurningunni.

Hvað fór mikil orka inn í tilraunina?

Hvað kom mikil orka út úr tilrauninni?

Ef það fyrra var stærra en það síðara er þetta ekkert nýtt.

Væri það á hinn veginn hefði það verið stórfrétt á forsíðum allra helstu fjölmiðla sem lausn á helstu vandamálum mannkyns.

 Allt rétt hjá þér. 

Samkvæmt Lin Boquiang, forstöðumanni Kínamiðstöðvar í orkuhagfræðirannsóknum við Xiamen háskóla, mun það taka áratugi þar til starfandi hvarfakljúfur rís úr tilraunastigi.

According to Lin Boquiang, the director of the China Center for Energy Economics Research at Xiamen University, it will take decades for a working reactor to emerge from its experimental stages.
