Tojsiab
Cov kws tshawb fawb ntawm Lawrence Livermore National Laboratory hauv California tau tswj kom tau txais lub zog ntau dua los ntawm cov tshuaj tiv thaiv nuclear ntau dua li lawv muab tso rau hauv los ua rau nws, US Department of Energy tshaj tawm Hnub Tuesday, cov kws tshaj lij tshaj lij tau hais Forbes yog ib kauj ruam loj heev rau kev tsim lub zeem muag uas tsis muaj kev txwv ntawm lub zog huv uas tej zaum tseem muaj ntau xyoo lawm thiab yuav tuaj txog lig dhau los daws cov teeb meem nyuaj tshaj plaws hauv kev tawm tsam kev hloov pauv huab cua.

Cov Lus Tseem Ceeb
Cov kws tshawb fawb tau pom qhov kev sib txuas ntawm lub hnub qub-lub hnub qub-powering txheej txheem uas sib xyaw cov ntsiab lus sib zog xws li hydrogen thiab helium rau hauv hnyav dua thiab tso tawm lub zog-rau ntau xyoo tab sis tau tawm tsam kom ua tiav lub zog nce vim lub zog hnyav uas xav tau los ua kom muaj kev sib haum xeeb.
Kev ua kom tau txais lub zog nce ntxiv yog "qhov tseem ceeb loj" rau kev tshawb fawb fusion thiab "txog txoj hauv kev rau kev siv zog fusion," Troy Carter, tus kws kho mob ntshav ntshav ntawm University of California, Los Angeles, hais rau Forbes.
Kev tsim lub tshuab uas tuaj yeem siv fusion yuav ua rau peb "qhov tseem ceeb ntawm lub zog huv huv," piav qhia Todd Allen, tus xibfwb ntawm nuclear engineering ntawm University of Michigan, txawm hais tias nws tau sau tseg tias qhov no yuav siv sijhawm ntau xyoo vim tias muaj "qee yam nyuaj" rau. yuav tackled zoo li ua kom cov tshuaj tiv thaiv mus ntev lub sij hawm thiab ntes lub zog affordably.
Aneeqa Khan, tus kws tshawb fawb hauv nuclear fusion ntawm University of Manchester, tau qhuas txog "cov txiaj ntsig zoo thiab zoo siab" tab sis hais rau Forbes nws tsis suav txog lub zog xav tau los khiav cov lasers uas muaj cov tshuaj tiv thaiv fusion lossis lwm yam tsis muaj txiaj ntsig lossis kev poob hauv cov txheej txheem, txhua yam yuav tsum raug suav rau thaum tsim cov nroj tsuag kev lag luam.
Khan tau hais tias "Peb tseem yog ib txoj hauv kev tawm tsam kev lag luam," uas txhais tau hais tias kev sib xyaw ua ke "tsis tuaj yeem pab peb nrog kev kub ntxhov huab cua tam sim no."
Ajay Gambhir, tus kws tshawb fawb laus ntawm Imperial College London Grantham Lub Tsev Haujlwm rau Kev Hloov Kho Kev Nyab Xeeb thiab Ib puag ncig, pom zoo, qhia Forbes Nws muaj keeb kwm siv cov thev naus laus zis tsim hluav taws xob "ntau xyoo dhau los mus los ntawm kev sim ntsuas kev ua lag luam mus rau kev lag luam" thiab qhov kev lag luam cuam tshuam rau fusion "yuav tuaj yeem nyob ntev li ob peb xyoos," dhau qhov taw qhia thaum kev txheeb xyuas qhia tias tsim hluav taws xob yuav tsum tau decarbonized.

Cov kws tshawb fawb ntawm National Ignition Facility ntawm Lawrence Livermore National Laboratory tau ua tiav fusion ignition rau lub Kaum Ob Hlis 5, US Department of Energy tshaj tawm Hnub Tuesday, kos thawj thawj zaug hauv keeb kwm uas qhov kev sim fusion tswj tau tsim lub zog ntau dua li tau siv los ua rau nws. "Tsuas hais tias, qhov no yog ib qho ntawm cov kev tshawb fawb zoo tshaj plaws ntawm lub xyoo pua 21st," Tus Thawj Saib Xyuas Hluav Taws Xob Jennifer Granholm tau hais rau hnub Tuesday, hais tias txoj kev txhim kho yuav "ua kom peb lub teb chaws muaj kev ruaj ntseg" los ntawm kev txhim kho US lub peev xwm nuclear thiab "tshem peb ib kauj ruam tseem ceeb los ze dua. kom muaj peev xwm ntawm xoom-carbon ntau fusion zog powering peb haiv neeg. "

Lub sij hawm cuam tshuam nrog kev tsim fusion raws li lub zog loj dhau los pab nrog kev txhawj xeeb txog huab cua hnyav tshaj plaws, uas cuam tshuam nrog kev txo qis ntawm cov pa roj carbon emissions tam sim ntawd. "Fusion twb lig dhau lawm los daws qhov teebmeem kev nyab xeeb," Khan hais Forbes "Peb twb tau ntsib kev puas tsuaj los ntawm kev hloov pauv huab cua thoob ntiaj teb, saib cov dej nyab hauv Pakistan, dej nyab hauv Suav teb thiab Europe lub caij ntuj sov no ib leeg." Cov kws tshaj lij ceeb toom txog kev daws cov teeb meem no thiab kev txo qis carbon tsis tuaj yeem tos xyoo lossis ntau xyoo los pib thiab Gambhir tau hais tias ntau qhov kev tshuaj ntsuam xyuas ntawm kev ua tiav net-zero los ntawm 2050 qhia tias lub ntiaj teb hluav taws xob yuav tag nrho decarbonized los ntawm 2040. Khan tau hais tias nws yog ib qho tseem ceeb kom muaj ob qho tib si ntev thiab luv. - cov tswv yim lub sij hawm, ntxiv peb yuav tsum tau siv cov pa roj carbon tsawg uas twb muaj lawm technologies xws li nuclear fission thiab renewables thaum "kev nqis peev nyob rau hauv fusion rau lub sij hawm ntev."
Dab Tsi Peb Tsis Paub
Ntev npaum li cas fusion yuav siv sijhawm. Nws tau ua qhov kev tso dag ntev ntev hauv thaj teb uas fusion tsuas yog ob peb xyoos dhau los rau ntau xyoo lawm. Txhua tus kws tshaj lij Forbes tau hais kom qhia txog qhov tseem ceeb ntawm qhov kev tshawb nrhiav tab sis hais txog cov kev sib tw tseem ceeb thiab kev tshawb fawb nyob rau pem hauv ntej kom ua kom fusion siv tau. Allen, leej twg hais Forbes nws tsis yog tus neeg twv ua ntej zoo thaum ntsuas thaum fusion yuav npaj tau, hais tias nws kwv yees nws yog "tseem ob peb xyoos" deb. Qhov tseem ceeb ntawm cov nyiaj ntiag tug thiab pej xeem tuaj yeem thawb qhov no mus sai dua, nws hais ntxiv. Carter hais Forbes Nws yog qhov tseem ceeb tshaj plaws los hais txog "kev xav ua lag luam thiab kev tsim kho tshiab" ntau dua li lub sijhawm, taw qhia rau cov thawj coj ntawm Tsev Dawb tsis ntev los no txhawb fusion thiab kev nqis peev tseem ceeb hauv kev lag luam. Qee qhov kev pib tsim los txhim kho cov nroj tsuag ntawm qhov ntsuas ntawm kaum xyoo lossis tsawg dua, nws hais ntxiv.
Tus Keeb Kwm Tseem Ceeb
Cov kws tshawb fawb tau nrhiav kev sib xyaw ua ke nuclear rau ntau xyoo lawm, pom tias nws yog qhov muaj peev xwm muaj zog ntsuab ntsuab. Nws raug suav hais tias yog ntsuab vim nws tsis emit carbon thiab txawm tias nws tseem tsim cov pov tseg - qee cov khoom lag luam yog cov xov tooj cua - qhov no yog tswj tau thiab tsis tshua muaj kev phom sij tshaj qhov uas tsim los ntawm nuclear fission. Nws muab cov khoom siv hluav taws xob yuav luag tsis muaj kev txwv vim muaj ntau ntawm cov roj siv - cov roj tseem ceeb yog ib qho hnyav ntawm hydrogen pom hauv dej hiav txwv - uas Carter hais tias tuaj yeem "muab lub zog txaus rau lub ntiaj teb rau ntau pua txhiab xyoo yog tias tsis yog. tsheej lab ntawm xyoo.
