Enye yeengxaki ezinkulu zamandla elanga kwaye, ngokubanzi, amandla ahlaziyekayo kukugcina kwayo ukusetyenziswa kwayo kamva. Zombini indawo yokugcina kunye nezothutho ziingxaki ekufuneka zisonjululwe ukuze izinto ezivuselelekayo zifumane ukhuphiswano kwaye zenze indlela yazo ngakumbi nangakumbi kwiimarike zamanye amazwe.
Ukunciphisa le ngxaki yokugcina, iqela labaphandi abavela kwiYunivesithi yaseChalmers yeTekhnoloji eGothenburg (eSweden) ibonakalisile ukuba kunokwenzeka ukugcina amandla elanga ngqo kulwelo lwamachiza, ebizwa ngokuba yimolekyuli yelanga. Isebenza njani ngokuchanekileyo?
Ukugcinwa kwamandla elanga
Njengoko benditshilo ngaphambili, ukugcina amandla elanga esiwavelisela ukusetyenziswa kamva yinto enzima kwaye ibe sisiphumo sophando olunokusombulula. Obu buchule bokusebenzisa ulwelo lwekhemikhali ukugcina amandla elanga bubonisa ukuba bunokufezekiswa ngenxa yemixokelelwane yeekhemikhali. Ikwavumela ukuba ikhutshwe xa siyifuna ngokwemfuno yethu yamandla elanga.
Okhokela iqela lophando lwala manzi nguNjingalwazi uKasper Moth-Poulsen kwaye ucacisile ukuba ukudibanisa ukugcinwa kwemichiza yamandla neepaneli ezishushu zelanga. ivumela uguquko olungaphezulu kweepesenti ezingama-80 zokukhanya kwelanga okungenayo.
Usebenza njani ngokuchanekileyo umbane?
Xa iamolekyuli yolwelo ibethwa ziifoto zokukhanya ezivela kwimitha yelanga, ziyakwazi ukutshintsha imilo kunye nokugcina amandla. Le nkqubo yokugcina iyakwazi ukuxhasa imijikelezo yokugcina eyi-140 njengebhetri eqhelekileyo. Iyakwazi ukukhupha amandla ngokuthotywa okungahoywanga.
Iprojekthi yophando yolwelo yaqala kwiminyaka emi-6 eyadlulayo kwaye yapapashwa kwincwadi yezenzululwazi i-Energy neNdalo, enkosi kwiDyunivesithi yaseChalmers. Ekuqaleni kophando, amandla okuguqula amandla elanga ibingu-0,01% kwaye i-ruthenium, into ebiza kakhulu, idlale eyona ndima ibalulekileyo kule nkqubo. Ngophuculo nophuhliso lweprojekthi, Ngalo lonke ixesha kunokwenzeka ukufikelela kwinkqubo ekwaziyo ukugcina i-1,1% yelanga eliwa njengamandla amachiza ehlala ihleli kude kube ngumzuzu wemfuno, kulapho ikhutshwa khona. Olu luphuculo lwento eyi-100. Ngapha koko, i-ruthenium ithathelwe indawo zizinto ezingabizi kakhulu esekwe kwikhabhoni.
