Eqinisweni, lezi zibani ezikhanyayo cishe azifani nalokho okuthiwa ama-tubini aseFinnish. Zenziwe nje zisontekile futhi zincane. Kukhona impikiswano enkulu mayelana nezinzuzo kanye nokulimaza kwalesi sakhiwo, kodwa iqiniso lihlala: ligcina imali ngempela, futhi ikhono lokulawula hhayi nje kuphela amandla, kodwa futhi umbala wokukhanyisa uyathandwa ngabathengi abaningi.
Ingabe izibani zokulondoloza amandla zilimaza?
Ake siqale ngecala eliphambene nalo lwemali, okungukuthi amaminithi walesi sibani. Okokuqala, kufanelekile ukuqonda leyo ngozi. Idizayini inikeza ukusetshenziswa kwe-mercury vapor, eyingozi kubantu , uma nje ingilazi iphukile. Lokhu, mhlawumbe, impendulo yombuzo ovame ukuthi ngabe izibani zokulondoloza amandla ziyingozi: uma ubaphatha ngokucophelela futhi ulandela yonke imiyalo, khona-ke ngeke kube khona umonakalo.
Isici sesibili esicacile sibhekene nendaba yokubuyisela kabusha izibani zokulondoloza amandla. Uma izibani ezinjalo zithengwa yibhizinisi, kuphoqelekile ukuba uphethe isivumelwano nomthengisi noma umdayisi ngokulahlwa. Gcina izibani ezisetshenzisiwe futhi ngokufanele kuziqukathi ezihlukene. Kodwa kumthengi ojwayelekile, umbuzo wokuthi ungasebenzisa kanjani izibani zokulondoloza amandla uhlala uvulekile. Ukuziphonsa endlebeni akukwazi ngezizathu ezicacile ezihlobene nomklamo. Empeleni, lo msebenzi uphelela ekutholeni amaphuzu wokuthola amabhethri edolobheni lakho. Njengomthetho, kuzothuthukisa futhi iphuzu lokuthola izibani ezisetshenzisiwe.
Amakhansela angcono kakhulu okusindisa amandla angeke akhokhe i-penny futhi alungele ukuchitha imali ehloniphekile. Uma ukhubeka ngokumangalisa okunjalo, qiniseka ukuthi ubuza umdayisi ngesifanekiso esimisiwe sesibani sokulondoloza amandla. Uma uthenga esitolo esiphenduwe kahle, ngokuvamile ayikho izinkinga.
Amandla ama-light-saving-bulbs
Uma konke kudabukisayo, kungani-ke ukufunwa kwezibani ezinjalo kuphazamisa? Into ewukuthi ama-light bulb-light bulbs anezinzuzo nezindleko, kodwa kunezikhathi ezinhle kakhulu.
Okokuqala kuqondene nokuphila kwezinsizakalo zezibani zokulondoloza amandla. Njengomthetho, iphasela libiza iminyaka engama-12 000 amahora. Kodwa lokhu kulungile, ngokuvamile kuya emafenjini amaningi ayenayo. Ukuphila kwangempela kwezibani zokulondoloza amandla kuyashintsha kungakapheli amahora ayizinkulungwane ezingu-7. Uma uqhathanisa nesevisi esheshayo ye-bulb evamile emahoreni ayizinkulungwane ezingu-1, inzuzo iyabonakala.
Okulandelayo, thinta izinga lokushisa kwezibani zokulondoloza amandla. Ngokuvamile azifudumali, ngoba zifanelekile ezimweni zokushisa zokushisa. Kuzo azikho okuthiwa i-pulsation yokukhanya futhi amehlo akhathali ngisho nalapho esebenza kukhompyutha. Futhi ngempela inzuzo ecacile kakhulu ukusetshenziswa kwamandla aphansi.
