Imbali yokukhusela umbane iqala ngeminyaka yoo-1700, kodwa bekukho uphuhliso oluncinci kwitekhnoloji. I-Preventor 2005 yanikezela ngobuchule bokuqala obuphambili kwishishini lokukhusela umbane ukusukela oko yaqala ngeminyaka yoo-1700. Enyanisweni, nanamhlanje, iimveliso eziqhelekileyo ezinikezelwayo zihlala zizintonga zombane ezincinci zemveli ezidityaniswe nomxube weentambo eziveziweyo - ubuchwepheshe obususela ngeminyaka yoo-1800.

1749 – Intonga kaFranklin.Ukufunyanwa kwendlela umbane ohamba ngayo kusikhumbuza umfanekiso kaBenjamin Franklin emi kwisiphango esivuthuzayo ephethe elinye icala lekhayithi elinde ukuba umbane ubethe. Ngexesha “lokuvavanya kwakhe ukufumana umbane emafini ngentonga etsolo,” uFranklin wenziwa ilungu elisemthethweni leRoyal Society ngo-1753.Kangangeminyaka emininzi, lonke ukhuselo lombane lwaluquka iFranklin Rod eyenzelwe ukutsala umbane nokuwuhlasela. Yayingasebenzi kakuhle kwaye namhlanje ithathwa njengeyakudala. Ngoku le ndlela ithathwa njengeyanelisayo kuphela kwiinqaba zecawa, iitshimini ezinde zemizi-mveliso kunye neenqaba apho iindawo eziza kukhuselwa zingaphakathi kwikhowuni.

1836 - Inkqubo yeFaraday Cage.Uhlaziyo lokuqala lwentonga yombane yayiyikheyiji yaseFaraday. Le yindawo ebiyelweyo eyenziwe ngemesh yezinto zokuqhuba eluphahleni lwesakhiwo. Ithiywe ngegama lesazinzulu saseNgilani uMichael Faraday, owayisungula ngo-1836, le ndlela ayanelisi ngokupheleleyo kuba ishiya iindawo ezisembindini wophahla phakathi kweekhontraktha zingakhuselekanga, ngaphandle kokuba zikhuselwe zii-air terminals okanye iikhontraktha zophahla ezikumgangatho ophezulu.

• Kwinkqubo yeFaraday, ukhuselo lombane lwenziwe ngeentonga ezininzi zombane, ezingaphantsi kwenyawo enye ukuphakama, ezinamathele kuzo zonke iindawo ezibonakalayo eluphahleni. Kufuneka zidityaniswe kunye nee-roof conductors kunye nee-down conductors ezininzi ukuze zenze ikheyiji engaphantsi kweenyawo ezingama-50 x iinyawo ezili-150 kwaye zibe nee-air terminals kwiindawo ezidibana kuzo iindawo zophahla oluphakathi.
  Isakhiwo esiboniswe apha singama-150 ft. x 150 ft. x 100 ft. ukuphakama. Indlela yeFaraday ibiza kakhulu ukuyifaka, ifuna izixhobo ezininzi eluphahleni kunye nokungena okunininzi eluphahleni...kodwa kude kube phakathi kweminyaka yoo-1900, bekungekho nto ingcono.

• 1953 - Umthinteli.I-Preventor sisikhululo somoya esikhupha i-ionizing esisebenza ngokuguquguqukayo. U-JB Szillard waqala ukuzama izixhobo zokukhanyisa ezikhupha i-ionizing eFransi, kwaye ngo-1931, uGustav Capart wanelungelo lobunikazi kweso sixhobo. Ngo-1953, unyana kaGustav uAlphonse waphucula isixhobo sikayise esiguqukayo, kwaye ukuyila kwakhe kwaphumela kwinto esiyaziyo namhlanje njenge-Preventor.
  I-Preventor ka-2005 yagqitywa kamva yiHeary Brothers yaseSpringville, eNew York.
  Izithinteli zisebenza ngokuguquguqukayo, ngelixa iindlela zangaphambili zingashukumi. Umzekelo, xa ilifu lesiphango lisondela kwisakhiwo esikhuselweyo, intsimi ye-ion yombane phakathi kwelifu nomhlaba iyandiswa. Ii-ion ezihlala ziphuma kwiyunithi, zithwala ezinye zee-ion zomhlaba zitshaja ziye efini, kwaye oku kunefuthe lokunciphisa okwethutyana amandla entsimi ye-ion phakathi kwelifu nomhlaba. Kufuneka kuqondwe ngokucacileyo ukuba ayinakuyitshintsha ilifu. Ayenzi nto ngaphandle kokunciphisa uxinzelelo ngexesha elincinci apho ilifu lidlula ngaphezulu - kodwa oku kunciphisa okwethutyana uxinzelelo ngamanye amaxesha kwanele ukuthintela ukukhupha kombane ekuqaliseni. Kwelinye icala, xa oku kunciphisa uxinzelelo kungonelanga ukuthintela ukuqalisa, kubonelelwa i-ion streamer yokuqhuba ukukhupha ngokukhuselekileyo kwinkqubo yomhlaba/yomhlaba.
  I-Heary Brothers ibiseshishini ukusukela ngo-1895 kwaye yeyona nkampani inkulu nendala kakhulu yezixhobo zokukhusela umbane emhlabeni. Abazenzi nje kuphela iPreventor, kodwa bakwaqinisekisa nokusebenza kwayo. Esi siqinisekiso sixhaswa yi-ipolisi yeinshorensi yemveliso yezigidi ezilishumi zeerandi.
