Umsebenzi upeyinta umphandle wekhaya elitshaImifanekiso ka-Abid Katib / Stringer / Getty Abantu bayaqhubeka nokutya ukutya okunciphileyo kwezibaso. Ngenxa yokuqhubeka kokutshiswa kwe-oyile, ukuqhubela phambili kunye nokuphunyezwa kwamandla azinzileyo kuye kwabaluleka ngakumbi. Ngelixa i-US yenze umda obonakalayo kumandla acocekileyo kwesiqingatha senkulungwane sokugqibela, ukuxhomekeka kwayo kwizibaseli zefossil kusothusa. Ngokwe- I-Arhente yokuKhusela iNdalo , ukutshiswa kwamafutha eefosili kwakunoxanduva lweepesenti ezingama-79 zokukhutshwa kwegesi kwi-greenhouse yase-US ngo-2010. Kungade kubonakale ngathi isizwe sithathe amanyathelo sibuyele umva kwindlela yamandla azinzileyo (ukukhohlela, ukuphuma kweParis, ukukhwehlela).
Kodwa ithemba elitsha lamanye amandla lisondele. Iqela labaphandi kwiYunivesithi iRMIT eOstreliya benze itekhnoloji entsha abathi yipeyinti yelanga. Oko kunokuvakala ngathi luhlobo olutsha lwepaneli yelanga, kodwa eneneni bubuchwephesha obahluke ngokupheleleyo, kwaye obufanele ukungqina ukuba bunexabiso eliphantsi kakhulu. (Inkqubo yephaneli yelanga eyi-5 ixabisa malunga ne- $ 25,000- $ 35,000.)
UGqr. Torben Daeneke, ongomnye wabaphandi abaziintloko abalandela obu buchwephesha butsha, uthethe naye Uphando lweGate malunga neenkcukacha zepeyinti yelanga kunye nesayensi engemva kwayo.
Ipeyinti yethu yelanga inamalungu amabini: isicoci esifunxa ukufuma esikwenzileyo kunye nokukhanya okufunxa i-titanium oxide, utshilo. Amasuntswana e-titanium oxide afunxa ukukhanya elangeni kwaye awuguqule ube ngamandla ombane. Kuba i-titanium oxide inxibelelana ngokusondeleyo ne-catalyst yokufunxa ukufuma, la mandla elangeni afunyenwe angadluliselwa ngokuthe ngqo kwi-catalyst, apho isetyenziselwa ukwahlula amanzi kunye nokuvelisa i-hydrogen. I-catalyst yethu ephucukileyo inesakhono sokufunxa ukufuma okungaphezulu okuvela kumoya ofumileyo, okhokelela ekubeni ikwazi ukwahlula ngokuqhubekayo amanzi kusetyenziswa amandla abonelelwa lilanga. I-hydrogen kufuneka ibanjwe ukuze igcinwe ize isetyenziswe kamva.
UDaeneke uqhubeke wathetha malunga nokusetyenziswa kwetekhnoloji entsha, kunye namanyathelo alandelayo okufumana itekhnoloji entsha kubathengi.
Ifotokopi (in chemistry, ifotokopi kukukhawulezisa ukusabela kwamachiza ngokukhanya)Iipeyinti zinokufumana usetyenziso kwiindawo ezininzi, enye inokubakho kwimveliso yehydrogen njengamandla okuphatha, ecaleni ifotovic (isebe lobuchwephesha elichaphazelekayo kwimveliso yombane kwindawo yokudibana kwezinto ezimbini) ukuvelisa umbane ohlaziyekayo, utshilo. Amanyathelo ongezelelweyo ayimfuneko ukuze ubone ngokupheleleyo ubungakanani bale teknoloji. Umzekelo, ekujoliswe kuko okulandelayo kukubandakanya le nkqubo kunye neembumba zokwahlula igesi eziya kuthi zivumele ngokukhethekileyo ukuvuna kunye nokugcina ihydrogen evelisiweyo.
UDaeneke uthelekise oku nenkqubo ye- ifotosinthesis kwizityalo.
IHydrogen kudala ithathwa njengomnye wemithombo ecocekileyo yamandla azinzileyo, evelisa kuphela amanzi njengemveliso , kodwa ayikamkelwa ngokubanzi njengomthombo wamandla ngenxa yeengxaki ezikhoyo ezinxulumene nemveliso kunye nokusebenza kweendleko. Ipeyinti yelanga inamandla okutshintsha yonke loo nto.
Okwangoku, imveliso hydrogen uxhomekeke kumbane Ukwahlulahlula i-H20 ibe ziimolekyuli zehydrogen kunye neoksijini. Ukongeza, amandla afunekayo ukuvelisa i-hydrogen anokuvela ekutshiseni i-fossil fuels, ngokungathandabuzekiyo ibeka amandla ekusebenziseni into yeekhemikhali njengendlela yamandla acocekileyo. Akukho nanye kwezi ndlela ineendleko ezifanelekileyo nokuba. Ngokusebenzisa iinkqubo zendalo zelanga ukubonelela ngamandla afunekayo ukwahlula iimolekyuli zehydrogen, ipeyinti yelanga inokuphelisa isidingo semveliso enexabiso kunye neyingozi exhomekeke kumbane okanye kwizibaso.
UDaenecke uxelele Eguqukayo ukuba itekhnoloji entsha inokusetyenziswa ecaleni kweepaneli zangoku zelanga ukunceda ukwandisa ukusebenza kakuhle kunye nokugubungela umphezulu womhlaba ongaphezulu onokubakho kwiindawo ezinokwaleka ezifumana ukukhanya okuncinci kakhulu ukuba zinokugqunywa ngokufanelekileyo ngeemodyuli zeseli zelanga ezibizayo. Uqhubeke nokongeza ukuba isenokuba yenye iminyaka emihlanu de ipeyinti ibethe iishelufa, kodwa kufanele ukuba ibe ngexabiso eliphantsi xa sele ithengisiwe ngokupheleleyo.
Ikamva ngokuqinisekileyo lijongeka liqaqambile kumandla elanga.
