Amabhawodi wokukhiya: ukhiye wobuchwepheshe obuqhubekayo? 

Uzwa ubuchwepheshe obuqhubekayo, futhi izingqondo zigxumela kumaphaneli elanga, ikhemistri yebhethri, noma izinqubo zokuvuselela kabusha. Akuvamile ukuthi umuntu acabange ngebhawodi yokukhiya ephansi. Lelo yiphutha lokuqala. Eminyakeni yami ngisebenza ezitezi zefekthri nasekubuyekezweni konjiniyela, ngibone amaphrojekthi amaningi kakhulu lapho ukulandisa okuzinzile kwakhelwe phezu kwemiklamo emikhulu, kuphela okubukelwa phansi ukwehluleka kwe-fastener-okuholela ekushintsheni ngaphambi kwesikhathi, imfucuza, kanye ne-carbon footprint ezungezayo. Umbuzo wangempela awukona ukuthi amabhawodi okhiye abalulekile, kodwa ukuthi indima yawo evame ukunganakwa—kusuka ekutholeni izinto ezibonakalayo kuya ekusebenzeni kwangaphakathi kwesevisi—empeleni inquma ukuthi ucezu lobuchwepheshe luhlala lusetshenziswa yini iminyaka engu-20 noma lulahlwe kwengu-5.

Ukugxila Okungafanele ku-Macro

Kuqala ngokuchema kokuhlela. Uma udizayina i-nacelle ye-wind turbine noma i-modular battery pack, izinto zamathikithi amakhulu zithola konke ukucutshungulwa. Ukucaciswa kwebhawodi? Ngokuvamile umcabango ongemuva, oyehliselwa kukhathalogi yezingxenye ezijwayelekile. Ngikhumbula iphrojekthi yesistimu ye-solar tracker lapho ithimba lonjiniyela lachitha khona izinyanga lithuthukisa ukusebenza kahle kwe-actuator. I ukukhiya ama-bolts ukuthola amajoyinti abalulekile acaciswe njenge-generic grade 8.8, atholakala ngokusekelwe kubhidi ephansi kakhulu. Kwakubonakala kukuhle ephepheni.

Kodwa ensimini, phakathi nezinyanga ezingu-18, saqala ukuthola imibiko yokushelela kwamalunga futhi, ezimweni ezimbalwa, ukuquleka okuyinhlekelele. Inkinga bekungelona ibanga, ngokwesilinganiso. Kwakuwuhlelo oluphelele lokucabanga olwalushoda. Amabhawodi abengagcini nje ngokuba nokucindezeleka kodwa ukudlidliza okuncane okuqhubekayo kanye nokuhamba ngebhayisikili okushisayo, ukuhlaziywa kwedizayini eyinhloko kwakuchazelwe kakhulu izingxenye ezinkulu. Ibhawodi yokukhiya kwakungeyona nje into yokuqinisa; kwakuyisici esibalulekile sokudambisa. Imodi yokwehluleka kwayo iholele ekutheni zonke izingalo ze-tracker zishintshwe, zingalungiswa. Kuningi kakhulu okuzuzwayo kokusimama okuvela ku-actuator esebenza kahle kakhulu.

Yilapho inkulumo idinga ukushintsha khona. Ukusimama akukhona nje amandla omkhiqizo owongayo lapho usebenza; imayelana nekhabhoni ehlanganisiwe ezintweni zayo kanye nokuphila isikhathi eside okuvimbela ukukhiqizwa okuphindaphindiwe. A Ibhawodi lokukhiya lokho kugqwala futhi kushaqe kushintsha iyunithi elungisekayo ibe umuntu ozolahla udoti. Sifunde ukucacisa amabhawodi hhayi nje ngomthwalo wokubopha, kodwa nokusebenza kwawo emvilophini ethile yendawo kanye nokugcinwa kwawo. Ngezinye izikhathi, lokho kusho ingxubevange ebiza kakhulu, eboshwe njenge-a ubuchwepheshe obuqhubekayo amandla, ngoba ivumela ukuqaqa kanye nokushintshwa kwezinga lengxenye iminyaka eyishumi phansi komugqa.

Izinto kanye Nenqubo: Izindleko Zomjikelezo Wempilo Efihliwe
