Umoya wawuvakala uphantsi, unesingqisho esivakalayo ngaphezu kokuvakalayo—uvakalelo lwamandla amakhulu abanjwe. UMnu. George, umphathi wezityalo onamava eForster onomsebenzi obhalwe kwezi holo zixineneyo, wema phambi kweqela labathengi abathandekayo, ilizwi lakhe licacile kwaye liqinisekile ngokuchasene ne-symphony yoomatshini.
“Wamkelekile, nonke, entliziyweni yolu tyando,” waqala uGeorge, ingalo yakhe ityibiliza iholo enkulu. “Oko ukuvayo sisandi samandla anokubakho esiba yi-kinetic, kwaye amandla e-kinetic esiba ngumbane ococekileyo nococekileyo. Namhlanje, ndiza kuba ngumkhokeli wenu kule nkqubo.”
Eli qela lamlandela lidlula kwizakhiwo ezinde, ezinombala okhrimu. UGeorge wema ecaleni kombhobho omkhulu wentsimbi owehla esilingini waza wanyamalala phantsi. “Le yipenstock,” wacacisa, ebetha isinyithi esipholileyo. “Ngumthambo wesityalo sethu. Amanzi avela edamini eliphezulu ngaphezu kwethu ahamba phantsi koxinzelelo olukhulu, eqokelela isantya namandla afunekayo kwinyathelo elilandelayo.”
Wabakhokelela kwindawo ephambili yeholo: i-turbine ngokwayo. Ngokungafaniyo nee-casing ezinkulu ezijikelezayo zee-turbines eziqhelekileyo, le yenzelwe ukubetha. “Sisebenzisa i-turbine yamavili ePelton apha, efanelekileyo kumthombo wethu wamanzi ohamba kancinci,” utshilo uGeorge, ekhomba ivili eliqinileyo, elifakwe ibhakede. “Uyayibona loo nozzle? Ijolisa amanzi kwi-jet enesantya esiphezulu ebetha la mabhakede ngamandla amakhulu, ijikeleza ivili. Yindlela yobunjineli echanekileyo—isebenzisa amandla, kungekuphela nje ubunzima.”
Umthengi wakhomba umngxuma omkhulu osuka kwi-turbine. "Kwaye loo nto iqhagamshela kwijenereyitha?"
“Kunjalo kanye!” uGeorge waqinisekisa, ebakhokelela kwelinye icala leyunithi. “Amandla ajikelezayo avela kwi-turbine ajikeleza i-rotor engaphakathi kwijenereyitha.” Wabonisa isandla sakhe kwicala elikhulu le-stator. “Apha, ngaphakathi kwentsimi yemagnethi, loo jiko loomatshini liguqulwa libe ngumsinga wombane. Kulapho umlingo wokwenyani wenzeka khona.”
Emva koko wakhokela iqela ukuya kwiqonga eliphezulu lokubukela, elinika umbono ocacileyo wesiphithiphithi esilawulwayo ngezantsi. Iibhanki zeemonitha kunye neepaneli zolawulo zazijikeleze udonga olukude. “Kwaye konke kulawulwa kwigumbi lethu lolawulo,” watsho. “Yonke i-volt, yonke i-ampere ijongwa kwaye ilawulwa apho ngaphambi kokuba ithunyelwe kwigridi. Le nkqubo yonke, ukusuka ekungeneni kwamanzi ukuya ekuphumeni kombane, izenzekela ngokuzenzekelayo ukuze isebenze kakuhle kwaye ikhuseleke, ngaphandle kokukhupha umbane.”
Omnye umthengi ubuze wathi, “Kuthekani ngamanzi emva kokuba egqibile umsebenzi wawo?”
UGeorge wancuma. “Umbuzo omhle kakhulu. Amanzi, amandla awo asetyenzisiweyo, awela kumdyarho wasemva kwendlu ongaphantsi kwethu aze akhululwe ngokukhuselekileyo abuyele emlanjeni osezantsi. Umjikelo uyaqhubeka kwaye uyaqhubeka.”
Njengoko uhambo luphela, uGeorge wajongana neqela. “Oku akusiyo nje imishini; bubungqina bobuchule bomntu obusebenza ngokuvisisana nendalo. Asikokuvelisa amandla kuphela; sibonelela ngesiseko esithembekileyo nesihlaziyekayo kumashishini akho nakuluntu lwakho.”
Abathengi, ngoku benombulelo omkhulu ngesandi esibangqongileyo, bashiya benokuqonda okucacileyo ngobunjineli obucocekileyo nobunamandla uForster kunye neqela lakhe ababebufunda yonke imihla.
