Umlando wokuvikela umbani usukela ngeminyaka yawo-1700, kodwa kube nokuthuthuka okuncane kobuchwepheshe.I-Preventor 2005 inikeze uguquko olusha lokuqala embonini yokuvikela umbani kusukela yaqala ngawo-1700.Eqinisweni, ngisho nanamuhla, imikhiqizo evamile ehlinzekwayo ngokuvamile imane iyizinduku zombani zendabuko ezincane ezixhunywe nezintambo ezisobala - ubuchwepheshe obaqala ngeminyaka yawo-1800.

Ngo-1749 - Induku kaFranklin.Ukutholakala kokuthi amandla kagesi ahamba kanjani kusikhumbuza isithombe sika-Benjamin Franklin emi ekuduma kwezulu ebambe ingxenye eyodwa yekhayithi futhi elinde umbani ukuthi ushaye.Ngenxa “yokuzama kwakhe ukuthola umbani emafwini ngentonga ecijile,” uFranklin wenziwa ilungu elisemthethweni leRoyal Society ngo-1753.Iminyaka eminingi, konke ukuvikela kombani kwakuhlanganisa i-Franklin Rod eklanyelwe ukuheha umbani futhi ibambe iqhaza phansi.Yayinokusebenza okulinganiselwe futhi namuhla ibhekwa njengendala.Manje le ndlela ngokuvamile ibhekwa njengenelisayo kuphela kuma-spire esonto, oshimula abade bezimboni kanye nemibhoshongo lapho izindawo okufanele zivikelwe khona ziqukethwe ngaphakathi kwekhoni.

Ngo-1836 - Uhlelo lweFaraday Cage.Ukubuyekezwa kokuqala kwenduku yombani kwakuyikheji yaseFaraday.Lokhu ngokuyisisekelo indawo ebiyelwe eyakhiwe yi-mesh yezinto zokuqhuba ophahleni lwesakhiwo.Iqanjwe ngososayensi oyiNgisi uMichael Faraday, owawasungula ngo-1836, le ndlela ayigculisi neze ngoba ishiya izindawo eziphakathi kophahla phakathi kwamakhondatha zingavikelekile, ngaphandle uma zivikelwe amatheminali omoya noma ama-roof conductor emazingeni aphezulu.

• ku-Faraday System, isivikelo sombani sihlanganisa izinti eziningi zombani, ezingekho ngaphansi kwefithi elilodwa ukuphakama, ezigxilwe kuwo wonke amaphuzu abalulekile ophahleni.Kumelwe ahlanganiswe ndawonye namakhondaktha ophahleni kanye namakhondakta amaningi aphansi ukuze akhe ikheji elingengaphezu kwamafidi angu-50 x 150 futhi abe namatheminali omoya ezimpambanweni zezindawo zophahla olumaphakathi.
  Isakhiwo esimelwe lapha siyi-150 ft. x 150 ft. x 100 ft. ukuphakama.Indlela ye-Faraday iyabiza ukuyifaka, idinga inani elikhulu lezinto zokusebenza ophahleni lwendlu kanye nokungena okuningi kophahla…kodwa kuze kube maphakathi nawo-1900, kwakungekho okungcono.

• 1953 - I-Preventor.I-Preventor iyitheminali yomoya ye-ionizing esebenza ngamandla.U-JB Szillard waqala ukuhlola ama-conductor okukhanyisa i-ionizing e-France, futhi ngo-1931, u-Gustav Capart wagunyaza umshini onjalo.Ngo-1953, indodana kaGustav u-Alphonse yathuthuka emshinini kayise wokuguqula izinto, futhi ukusungulwa kwayo kwaphumela kulokho esikwazi namuhla ngokuthi uMvikeli.
  I-Preventor 2005 yabe isisebenza kahle ngabakwa-Heary Brothers base-Springville, eNew York.
  Izinqamuli zisebenza ngokuguquguqukayo, kuyilapho, izindlela zangaphambili zimile.Isibonelo, lapho ifu lesiphepho lisondela esakhiweni esivikelekile, inkambu ye-ion kagesi phakathi kwefu nomhlabathi iyanda.Ama-ion ahlala egeleza esuka kuyunithi, athwala amanye amashaji e-ion ion aphansi aya ngasefwini, futhi lokhu kuba nomthelela wokwehlisa okwesikhashana ukuqina kwendawo ye-ion phakathi kwefu nomhlaba.Kumele kuqondwe ngokucacile ukuthi ayikwazi ukuqeda ifu.Akwenzi okungaphezu kokunciphisa ukushuba kwesimo isikhathi esincane lapho ifu lidlula phezulu - kodwa lokhu kuncipha kwesikhashana kokungezwani kwesinye isikhathi kwanele ukuvimbela ukuphuma kombani ukuthi kungaqali.Ngakolunye uhlangothi, uma lokhu kwehliswa kwengcindezi kungenele ukuvimbela ukuqala, i-conductive ion streamer inikezwa ukuze iqhube ukukhishwa ngokuphepha ohlelweni lomhlaba / lomhlabathi.
  I-Heary Brothers ibe sebhizinisini kusukela ngo-1895 futhi ingumkhiqizi omkhulu kunawo wonke wemishini yokuvikela umbani emhlabeni.Abagcini nje ngokwenza i-Preventor, kodwa futhi baqinisekisa ukusebenza kwayo.Isiqinisekiso sisekelwa yi-ainqubomgomo yomshwalense womkhiqizo wamadola ayizigidi eziyishumi.
