Akukhona okokuqala ku- ActualidadGadget Sikhuluma ngesihloko esibaluleke kakhulu kubantu ukuhlanganiswa kwenuzi. Ngaphambi kokuqhubeka, ngikukhumbuze ukuthi i-nyukliya fusion yinto esingakakwazi ukufinyelela kuyo kusukela, ngokungafani nalokho esikujwayele, okwenziwa yizikhungo zethu zamandla enyukliya namuhla yi-fission yenuzi, okungukuthi, esikhundleni sokujoyina ama-athomu amabili (i-fusion) abakwenzayo kwehlukana ngakunye (fission).
Lapho sesikucacisile lokhu, noma encazelweni sesishiye ama-nuances amaningi ukuze sithinte ukuqonda ngokweqiniso umehluko phakathi komqondo nomunye nomunye, namhlanje ngifuna sikhulume ngombhalo wakamuva obhekise kulolu daba olusanda kwenziwa enyatheliswa yiqembu lonjiniyela nabaphenyi abavela MIT, abaqinisekisa ukubonga ngokutholakala kwabo inganciphisa kakhulu izikhathi zentuthuko ukuze ukulawulwa kokuhlanganiswa kwenuzi kube ngokoqobo.
Iqembu lonjiniyela be-MIT bakholelwa ukuthi bathole indlela yokunciphisa isikhathi esidingekayo sokuthuthukiswa kwe-fusion yenuzi ngesigamu
Ukuze uqonde ukuthi udaba lokuhlanganiswa kwenuzi namuhla lunjani, akutshele ukuthi namuhla kunezindlela ezintathu ezingahle zenziwe zokuqinisekisa ukuthi abantu bangazithokozela zonke izinzuzo zamandla ezithembiswa ukuhlanganiswa kwenuzi. Lezi zindlela ezintathu zidlula kumaphrojekthi we-ITER, IFMIF DONES noma we-DEMO, amaqembu amaqembu abo amakhulu okucwaninga aqinisekisa ukuthi, okungenani kuze kube yingxenye yekhulu leminyaka, ngeke bawuphothule umsebenzi wabo, ngakho-ke sikhuluma, noma ngaphezulu noma ngaphansi, ngokulinda ukuthi kungathatha iminyaka engaphezu kwengu-30.
Siyabonga ngqo ngokutholwa okwenziwe yi-MIT, kubonakala sengathi lezi zinsuku zokugcina zinganqunywa phakathi. Ngokuningiliziwe, akutshele ukuthi lolu cwaningo lwenziwe ngokuhlanganyela nabaphenyi beCommonwealth Fusion Systems, inkampani ezimele ekhethekile ekuhlanganisweni kwenuzi. Emsebenzini sinikezwa i- i-superconductor entsha engasetshenziswa ekwenziweni kwe- isizukulwane esisha samagnet enamandla kakhulu futhi ahlangene kulezo ezisetshenziswa njengamanje ngamakhemikhali ambalwa e-fusion nuclear akhiwe noma, ukwehluleka lokho, ayakhiwa.
Ngenxa ye-superconductor entsha sizokwazi ukukhiqiza odonsa abancane abaqinile nabanamandla okwakha ophendulayo kuze kube ngama-65 amancane kunalawa wamanje
Mayelana nendima yamagnet ekuhlanganisweni kwenuzi, ngikutshele ukuthi badlala indima ebaluleke kakhulu kusukela lapho banesibopho sokuvalela i-plasma, into engeyona enye into ngaphandle kwegesi engafinyelela ezingeni lokushisa elicishe lifinyelele ezigidini ezingama-XNUMX degrees Celsius. Lo gesi ubhekene nokuxuba i-deuterium ne-tritium nuclei, ngaleyo ndlela yakha i-helium nucleus eyodwa ne-neutron enamandla amakhulu.
Omunye wemisebenzi emihle odonsa uzibuthe kulolu hlobo lwama-reactor ukwenza yenza ingcindezi eyanele phakathi kwe-deuterium ne-tritium nuclei ukuze, ngosizo lokushisa okuphezulu kwe-plasma, bobabili bahlangane. Kuleli qophelo, ososayensi ababambe iqhaza ekwakhiweni kwale phrojekthi baqinisekisa ukuthi ukwakhiwa kwale superconductor kuzobavumela ukuthi bakhe ozibuthe abanamandla futhi abanamandla, okungahumushela ekutholeni ubukhulu be-reactor bancishiswa cishe izikhathi ezingama-65.
Ukuhlanganiswa kwenuzi kufanele kuxazulule zonke izinkinga ezinkulu zamandla ezifunwa ngabantu namuhla
Ukuhlola ukusebenza kwephrojekthi, onjiniyela sebevele sebeqalile ukusebenza ekwakheni i-fusion reactor entsha, esibhabhadiswe ngegama le I-SPARC nokuthi, ngokusho kwemidwebo yokuqala, njengoba kukhonjisiwe, kuzoba kuncane izikhathi ezingama-65 kune-ITER.
Iphuzu elilodwa elincoma ukusetshenziswa kwalesi sizukulwane esisha sikamazibuthe ukuthi, njengoba zinamandla amakhulu, ama-cores e-plasma angabhekana nengcindezi ephakeme kakhulu, yona ehumushela bekungeke kudingeke ukuthi i-plasma ifinyelele izinga lokushisa elibi kakhulu. Ngaphansi kwalezi zimo ezithile, ukusebenza kahle kwamandla kufanele kube ngaphezulu, okungukuthi, ngeyunithi ngayinye yamandla adingekayo ukwenza ukuxubana singathola amayunithi amabili wamandla asebenzisekayo avela.
