Kuyo yonke imbali, abantu bazamile ukuqikelela ukuba kuya kuthatha ixesha elingakanani ukulumkiswa kwangaphambili. Izinto zendalo ezikwinqanaba elingaqhelekanga njengokuqhuma kwentaba-mlilo, izaqhwithi, izikhukula, iinyikima, itsunami, njl. Ukuthintela bekusoloko kuzanywa ukunciphisa iimpembelelo kunye nomonakalo onokubangelwa. Sinyanzelile ukuzama ukulawula okanye ukwazi into engalawulekiyo okanye engalindelekanga. Nangona kunjalo, khange siyeke ukucinga ngaloo nto kungcono ukuthatha ithuba lokubonakalisa indalo kwaye ulisebenzise.
Sithetha ngazo zonke iziganeko ezingaqhelekanga zendalo endizichazileyo ukukhupha isixa esikhulu samandla. Umzekelo, kwisaqhwithi somoya oshushu kunye neenkqwithela, umoya uphatha amandla amakhulu anokusetyenziselwa ukuvelisa amandla omoya. Umntu uzisebenzisa njani iziganeko zomhlaba?
Amandla akhutshwa ngumoya
Kwiinkanyamba kunye neenkqwithela zetropiki, umoya ovuthuzayo ufikelela kwisantya se-257 km / h kwaye ngaphezulu kwe-9 yeebhiliyoni zeelitha zemvula. Ngezi zixa zamanzi nomoya kunikwa amandla ngakumbi kunazo zonke izixhobo zeatom ehlabathini. Yiyo loo nto oososayensi bezama ukufumana indlela yokuwasebenzisa okanye bawathabathe onke la mandla kwaye bawagcine. Kule nto kufuneka bafumane umbandela othile vumela ukwenza ufakelo olunganyangekiyo ngokwaneleyo ukugcina onke amandla avelisiweyo kwaye kwangaxeshanye ukuxhathisa izinto ngaphandle kokutshatyalaliswa.
Ngenxa yamandla omoya siyakwazi ukusebenzisa amandla omoya ukuvelisa umbane. Nangona kunjalo, ukukhula koomatshini bomoya bekusoloko kugxilwe kumoya ophakathi. Ngamanye amagama, iiturbine zomoya zingasebenza ngokuchanekileyo ngemimoya emalunga ne-90km / h ubuninzi. Ukusuka kweso santya, amandla omoya kunokubangela umonakalo omkhulu kwizibonelelo, ke ayiloncedo kwimimoya enamandla kakhulu. Ngokwesiqhelo iincakuba zeinjini yomoya ziyilelwe umoya ophakathi.
Isizathu sokuba ukwakhiwa kunye nokuveliswa koomatshini bomoya abakwaziyo ukumelana nemimoya yenkanyamba khange kubekwe phambili ngenxa yokuba kukusetyenziswa kwexesha kakhulu kunye neendleko eziphezulu kakhulu kwimveliso. Nangona kunjalo, uphuhliso lweeinjini zomoya ezikwazi ukugqitha kwi-90 km / h ziyaphucuka. Sele zikhona iiturbines ezininzi esele ziphuhlisiwe ezinako ukuxhasa isantya ukuya kuthi ga kwi-144 km / h.
Ngaba umonakalo wenkanyamba ungancitshiswa?
Enye yezinto esizama ukuyijonga kukukwazi ukufunxa amandla aveliswa yinkanyamba kwaye ngaxeshanye sinciphise iimpembelelo kunye nomonakalo onokuthi ubange. Okwangoku inzululwazi iyakwazi ukuqikelela ixesha kunye nendawo apho iza kubakho inkanyamba. Ke ngoko, inyathelo elilandelayo abayifunayo kukwazi izinto ezenza izakhiwo ezinokumelana nomoya kwaye zikwazi ukugcina amandla.
Ukuphumeza oku, Abaphandi beYunivesithi yaseStanford (ECarlifonia, e-USA), phakathi kwabanye, benze izifundo kunye nokulinganisa kule ndawo, ngeziphumo ezimangalisayo. Benze ulinganiso lwendlela ifama yomoya enokusebenza ngayo eyayikwazi ukugcina amandla kwiinkanyamba kwaye imelane nayo ngaphandle kokuzibhubhisa. Baye necebo lokuba ukuba bangafaka iinjini zomoya ezizodwa ezinamacala amalunga ne-120 yeemitha ububanzi kwaye babekwa kwiimitha ezili-100 ngaphezulu kolwandle, baya kuba nakho ukusika amandla omoya wenkanyamba ngesiqingatha, bathathe amandla izaqhwithi, ukunciphisa isantya somoya kunye nokucothisa amaza ngesiqingatha. Ngamanye amagama, ifama yomoya yobukhulu obu iya kuba nakho ukuphazamisa inkanyamba njengoko ingaphula iluphu yengxelo eyenza ukuba inkanyamba yomelele kwaye yomelele.
Ezi projekthi kunye nemibono zimnandi kakhulu ngenxa yokuba ukuphazamisa inkanyamba kunokuba yinto entle kwindalo, nangona kunjalo ayisosicwangciso esisebenzayo. Ukuze ukwazi ukunqanda amandla amangalisayo enkanyamba Kuya kufuneka ukufaka amawaka omoya. Oku kwenza ukuba iprojekthi ingenakufikeleleka ngokwembono yezoqoqosho, kuba ayinakwenzeka. Kuyenzeka ukuba oku kube nakho ukusebenza, kwixesha elizayo ubume bezixhobo buya kuphinda bucingwe, kusenziwa oomatshini bomoya abakhulu ukunciphisa inani labavelisi.
