Ama-electronic anamandla elanga ayisinyathelo esisodwa sokusondela ekubeni ingxenye yansuku zonke yempilo yethu ngenxa yempumelelo entsha yesayensi “enkulu”.
Ngo-2017, ososayensi eyunivesithi yaseSweden benza uhlelo lwamandla okwenza kube lula ukuthwebula nokugcina amandla elanga kuze kube yiminyaka eyi-18, ukuwakhulula njengokushisa lapho kudingeka.
Manje abacwaningi sebephumelele ukwenza uhlelo lokukhiqiza ugesi ngokuluxhuma emshinini wokuphehla ugesi we-thermoelectric.Yize isesigabeni sawo sokuqala, umqondo othuthukiswe e-Chalmers University of Technology e-Gothenberg ungavula indlela yezinto zikagesi ezizishajayo esebenzisa amandla elanga agciniwe lapho kudingeka.
“Lena yindlela entsha yokuphehla ugesi ngamandla elanga.Kusho ukuthi singasebenzisa amandla elanga ukuze sikhiqize ugesi kungakhathaliseki isimo sezulu, isikhathi sosuku, inkathi, noma indawo,” kuchaza umholi wocwaningo uKasper Moth-Poulsen, onguSolwazi eMnyangweni Wezekhemikhali Nobunjiniyela Bamakhemikhali eChalmers.
Uyanezela: “Ngijabule kakhulu ngalo msebenzi."Sithemba ukuthi ngentuthuko yesikhathi esizayo lokhu kuzoba yingxenye ebalulekile ohlelweni lwamandla esizayo."
Amandla elanga angagcinwa kanjani?
Amandla elanga ashintshashintshayo ngenxa yokuthi ingxenye enkulu yawo, asebenza kuphela lapho kukhanya ilanga.Kodwa ubuchwepheshe bokulwa nalokhu kushiyeka okuxoxwe ngakho kakade sekwenziwe ngesivinini esisheshayo.
Ama-solar panel enziwe ngezitshalo ezilahlwayo ukuthiamunca ukukhanya kwe-UV ngisho nezinsuku ezinamafungenkathi'amaphaneli elanga ebusuku' badalwe lowo msebenzi ngisho selishonile ilanga.
Ukugcinwa isikhathi eside kwamandla abawakhiqizayo kungenye indaba.Isistimu yamandla elanga edalwe e-Chalmers emuva ngo-2017 yaziwa ngokuthi 'KAKHULU': Amasistimu Wokugcina Amandla We-Molecular Solar Thermal.
Ubuchwepheshe busekelwe ku-molecule eklanywe ngokukhethekile ye-carbon, i-hydrogen ne-nitrogen eshintsha isimo lapho ihlangana nokukhanya kwelanga.
Ishintshashintsha ibe 'i-isomer ecebile ngamandla' - i-molecule eyakhiwe ama-athomu afanayo kodwa ahlelwe ndawonye ngendlela ehlukile.I-isomer ingase igcinwe isesimweni esiwuketshezi ukuze isetshenziswe kamuva lapho idingeka, njengasebusuku noma ekujuleni kobusika.
I-catalyst ikhipha amandla alondoloziwe njengokushisa kuyilapho ibuyisela i-molecule esimweni sayo sangempela, ilungele ukusetshenziswa futhi.
Ngokuhamba kweminyaka, abacwaningi baye balungisa uhlelo kangangokuthi manje kungenzeka ukugcina amandla iminyaka eyi-18 emangalisayo.

Njengoba kuchaziwe ocwaningweni olusha olushicilelwe kuIseli Libika Isayensi Yezomzimbangenyanga edlule, le modeli manje isithathwe igxathu elingaphezulu.
Abacwaningi baseSweden bathumele i-molecule yabo eyingqayizivele, elayishwe amandla elanga, kozakwabo baseShanghai Jiao Tong University.Lapho amandla akhululwa aguqulwa abe ugesi kusetshenziswa ijeneretha ababeyikhiqizile.
Empeleni, ukukhanya kwelanga kwaseSweden kwathunyelwa kolunye uhlangothi lomhlaba futhi kwaguqulwa kwaba ugesi eChina.

Umcwaningi uZhihang Wang wase-Chalmers University of Technology uthi:
“Kuze kube manje, sikhiqize ugesi omncane kuphela, kodwa imiphumela emisha ikhombisa ukuthi lo mqondo uyasebenza ngempela.Kubukeka kuthembisa kakhulu.”
Idivayisi ingase ithathele indawo amabhethri namaseli elanga, ilungise kahle indlela esisebenzisa ngayo amandla amaningi elanga.

Ubuhle balolu hlelo oluvaliwe, oluyindilinga ukuthi lusebenza ngaphandle kokubangela ukukhishwa kwe-CO2, okusho ukuthi lunamandla amakhulu okusetshenziswa ngamandla avuselelekayo.
Iphaneli yakamuva ye-UN Intergovernmental Panel on Climate Change(IPCC) umbikoikwenza kucace kakhulu ukuthi sidinga ukuqongelela izinto ezivuselelekayo futhi sisuke kumafutha ezinto ezimbiwa phansi, ngokushesha okukhulu ukuze sivikele ikusasa lesimo sezulu esiphephile.
Nakuba intuthuko ebalulekile kuamandla elanganjengalokhu kunikeza ithemba, ososayensi baxwayisa ukuthi kuzothatha isikhathi ukuthi ubuchwepheshe buhlanganiswe ezimpilweni zethu.Kusasele ucwaningo oluningi nentuthuko ngaphambi kokuthi sikwazi ukushaja amagajethi ethu obuchwepheshe noma sishise amakhaya ethu ngohlelo lwamandla elanga agciniwe, bayaphawula.
“Kanye namaqembu ahlukahlukene ocwaningo afakwe kulo msebenzi, manje sisebenzela ukulungisa lolu hlelo,” kusho uMoth-Poulsen.“Inani likagesi noma ukushisa okungalikhipha kumele linyuswe.”
Wengeza ngokuthi nakuba lolu hlelo lusekelwe ezintweni ezilula kodwa ludinga ukulungiswa ukuze lungabizi kakhulu ukukhiqiza ngaphambi kokuthi lwethulwe kabanzi.
