Ingabe ugesi wamanzi uzoba yinto entsha enhle yokusindisa ugesi womhlaba esikhathini esizayo? Uma siqala ngokombono womlando, uzothola ukuthi kungakhathaliseki ukuthi isimo samandla sishintsha kanjani, ukusetshenziswa kukagesi wamanzi kuyanda emhlabeni.
Ezikhathini zasendulo ezikude, abantu babesebenzisa amandla amanzi ukushayela isondo lamanzi nokushayela umshini wokugaya ukuze banikeze amandla okunisela ekhaya nakwezolimo. Ngokuthuthuka kwezinhlangano ezimbili zezimboni, amandla kagesi angaphansi kwamanzi aye aziswa kakhulu. Injini yomusi inikeza ukuhlinzekwa kwamandla okwengeziwe emphakathini, ngakho abantu balangazelela kakhulu ukufuna isakhiwo samandla ngokunemba okuphezulu, ukulawula okunamandla kanye nokulula okungcono isikhathi esithile. Ngakho-ke, ukusetshenziswa kwenjini yomusi kanye namandla kagesi kuye kwakhuthaza ngokushesha intuthuko yesayensi nobuchwepheshe.
Ngo-1831, iFerrari yembula isimiso esiyisisekelo somphumela we-electromagnetic ngokusebenzisa inani elikhulu lokuhlola. Umphakathi we-physics uphinde wahlola okwengeziwe ngama-electric motors. Ikhulu le-19 lonke lalisenkathini kagesi ompofu kakhulu. Ngaleso sikhathi, bambalwa kuphela abantu emhlabeni ababengasebenzisa izibani ze-arc zikagesi ezibizayo. Kwaze kwaba yilapho isazi se-physics okuthiwa uWilliam Armstrong sihlanganisa ukusetshenziswa kwamandla kagesi kanye nejeneretha lapho lesi simo sashintsha kancane kancane.
Lo sosayensi wezothando usebenzise kangcono ukusungula kwakhe empilweni. Egqumeni elingaphandle kweRosberg, wasebenzisa izinzuzo zendawo ukuze ahlomise i-manor yakhe ngezinto eziningi ezinhle zamanzi nogesi, ngakho impilo yakhe yathola ukulula okuningi. Isibonelo, ungumuntu wokuqala emhlabeni ukusebenzisa umshini wokuwasha we-hydraulic. Waphinde wenza i-hydraulic lift ngokusebenzisa umphumela wamanzi nogesi.
Yisenzo sakhe esifakazela umhlaba ukuthi amandla ahlangene kagesi wamanzi awakwazi nje ukuthuthukisa kakhulu ukusebenza kahle kwezimboni, kodwa futhi kulindeleke ukuthi ashintshe impilo yabantu kanye nendlela yokukhiqiza. Ngo-1882, u-Edison wasungula uhlelo lokukhiqizwa kukagesi wamanzi, oluyisiteshi sokuqala sikagesi wamanzi emhlabeni. Lo msebenzi uphinde uphawule ukuqala kwesikhathi sikagesi wamanzi kubo bonke abantu.
Uma izinsizakusebenza zamandla ziyigazi lokuphila lamazwe amaningi, ukuthuthukiswa kwamandla kagesi ngamanzi kuyisisekelo esihle kakhulu sokukhuthaza intuthuko yezenhlalo yanoma yiliphi izwe noma isifunda. Inani elikhulu lemininingwane yomlando libonisa ukuthi amaphrojekthi kagesi ngamanzi angaholela emphumeleni ongcono wentuthuko yezikhathi. Ngakho-ke, amaphrojekthi ahlukahlukene kagesi ngamanzi nawo akhiwe ezifundeni ezahlukene. Isibonelo, iDamu laseHoover e-United States ngo-1931, iDamu laseVaian e-Italy ngo-1959, kanye neDamu laseThree Gorges eShayina ngo-2006.
Manje amazwe noma izifunda eziningi ziyaqaphela ukuthi azikwazi ukushiya ukuhlinzekwa kwamandla kagesi ukuze zilandele intuthuko yesikhathi eside. Ngakho-ke, amandla kagesi azoqhubeka nokuba khona isikhathi eside. Ngemva kwekhulu lama-21, amanani kawoyela emhlabeni wonke akhuphuke kancane kancane. Indawo yethu yemvelo ibhekene nokungcola okukhulu, futhi intuthuko yamandla kagesi ingakhuthaza ukulungiswa kwesakhiwo esisha samandla.
Ukuthuthukiswa nokusetshenziswa kwamandla kagesi angaphansi kwamanzi kuzoba yinkinga okufanele wonke amazwe amakhulu ayicabangele. Lapho ukuthuthukiswa kwamandla kuvula isandulela senkathi entsha, abantu babonakala bemi endaweni entsha yokuqala. Ubani ongaba nezinzuzo ezengeziwe ekufuneni amandla ahlanzekile esikhathini esizayo? Kuncike futhi ekutheni amazwe emhlabeni wonke angahlanganisa yini ijubane lokwakha, athathe intuthuko esimeme njengenhloso, asebenzise ngokugcwele indima ebalulekile yemithombo yamanzi ekukhiqizeni amandla, futhi ahlinzeke ngokulula okwengeziwe empilweni nasekukhiqizeni kwabantu, ukuze kuhlangatshezwane nezidingo eziningi zomphakathi.
Eqinisweni, imithombo yamanzi ayikwazi nje ukuba amandla ahlanzekile, kodwa futhi ingaba nenani eliphezulu lokuhlobisa kanye nelezivakashi. Isibonelo, iGansu Yongxing Silk Road International Travel Service Co., Ltd. ibilokhu ibhekene nomphakathi unyaka wonke, inikeza abasebenzisi ngobuqotho izinsizakalo ezisezingeni eliphezulu, inamathela enjongweni yebhizinisi yokusinda ngekhwalithi kanye nentuthuko ngedumela. Eminyakeni edlule, sithuthukise njalo inethiwekhi kazwelonke kanye nemodi yokuphatha eqondile, futhi sahola ekwakheni ibhizinisi elisezingeni eliphezulu elinophawu olukhulu.
