Nhoroondo yekudzivirira mheni inotangira kuma1700, asi kwave nekufambira mberi kushoma pakugadzira tekinoroji iyi. The Preventor 2005 yakapa hunyanzvi hwekutanga muindasitiri yekudzivirira mheni kubvira payakatanga kuma1700. Kutaura zvazviri, kunyange nhasi, zvigadzirwa zvakajairika zvinopihwa zvinowanzova zvimiti zvidiki zvemheni zvakabatana netambo dzakawanda dzakavhurika - tekinoroji inotangira kuma1800.

1749 - Rombo raFranklin.Kuwanikwa kwemafambiro emagetsi kunoita kuti tifunge nezvemufananidzo waBenjamin Franklin akamira mudutu remvura akabata mugumo wekaiti achimirira kuti mheni irove. Pakuyedza kwake "kuwana mheni kubva mumakore netsvimbo yakapinza," Franklin akaitwa nhengo yepamutemo yeRoyal Society muna 1753.Kwemakore mazhinji, nzira yese yekudzivirira mheni yaisanganisira Franklin Rod yakagadzirirwa kukwezva mheni uye kurwisa pasi. Yaive nekushanda kushoma uye nhasi inoonekwa seyechinyakare. Iye zvino nzira iyi inowanzoonekwa seyakakwana chete pamatanda echechi, machimini marefu eindasitiri uye shongwe umo nzvimbo dzinofanirwa kudzivirirwa dziri mukati mekoni.

1836 - Sisitimu yeFaraday Cage.Kugadziriswa kwekutanga kwetsvimbo yemheni kwaive keji yeFaraday. Iyi inzvimbo yakavharirwa yakagadzirwa nemesh yezvinhu zvinofambisa mhepo padenga rechivako. Yakatumidzwa zita remusayendisiti wekuEngland Michael Faraday, uyo akaigadzira muna 1836, nzira iyi haina kugutsa zvakakwana nekuti inosiya nzvimbo dziri pakati pedenga pakati pemakondirakita dzisina kudzivirirwa, kunze kwekunge dzadzivirirwa nema air terminals kana ma roof conductors ari padanho repamusoro.

• NeSisitimu yeFaraday, dziviriro yemheni inoumbwa nematanda emheni akawanda, asingasviki futi imwe chete, akaiswa panzvimbo dzose dzakakosha padenga. Anofanira kubatanidzwa pamwe chete nemaconductor edenga nemaconductor akawanda epasi kuti agadzire keji isingapfuure tsoka 150 x 150 uye ive nenzvimbo dzemhepo dzinosangana nenzvimbo dzedenga repakati.
  Chivako chinomiririrwa pano chine 150 ft. x 150 ft. x 100 ft. kureba. Nzira yeFaraday inodhura kuisa, inoda michina yakawanda padenga uye kupinda kwedenga kakawanda…asi kusvika pakati pemakore ekuma1900, hapana chakanga chiri nani pane izvi.

• 1953 - Mudziviriri.Chinotadzisa kufambiswa kwemhepo chinopa ionizing uye chinoshanda nesimba. JB Szillard akatanga kuyedza maconductor emwenje anopa ionizing muFrance, uye muna 1931, Gustav Capart akapa patent yechishandiso chakadaro. Muna 1953, mwanakomana waGustav Alphonse akavandudza chishandiso chababa vake, uye hunyanzvi hwake hwakaguma nechinhu chatinoziva nhasi seChinotadzisa kufambiswa kwemhepo.
  Mutambo wePreventor 2005 wakazogadziriswazve neHeary Brothers vekuSpringville, New York.
  Zvinodzivirira zvinoshanda nesimba, nepo nzira dzekare dzisingachinji. Semuenzaniso, kana gore remhepo rasvika pachivako chakachengetedzwa, munda wemagetsi weion uri pakati pegore nepasi unowedzera. Maion anogara achiyerera kubva muyuniti, anotakura mamwe eion yepasi achienda kugore, uye izvi zvine simba rekudzikisa simba remunda weion pakati pegore nepasi kwenguva pfupi. Zvinofanira kunzwisiswa zvakajeka kuti hazvigone kudzikamisa gore. Hazvingopfuuri kuderedza kushushikana kwenguva diki iyo gore riri kupfuura pamusoro - asi kudzikiswa kwechinguvana kwekumanikidzwa uku dzimwe nguva kwakakwana kudzivirira kuburitsa kwemheni kubva pakukonzera. Kune rumwe rutivi, kana kudzikiswa uku kwekumanikidzwa kusina kukwana kudzivirira kukonzera, streamer yeion inofambisa inopihwa kuti itungamire kuburitsa kwakachengeteka kuenda kupasi/pasi system.
  Heary Brothers yave iri mubhizinesi kubvira muna 1895 uye ndiyo kambani huru uye yekare yekugadzira michina yekudzivirira mheni pasi rose. Havangogadziri chete Preventor, asiwo vanovimbisa kushanda kwayo. Vimbiso iyi inotsigirwa nekambaniinishuwarenzi yezvigadzirwa ine mamiriyoni gumi emadhora.
