Nhoroondo yekudzivirira mheni yakatanga kusvika kuma1700, asi kwave kune zvishoma kufambira mberi kune teknolojia.Iyo Preventor 2005 yakapa yekutanga hunyanzvi hunyanzvi muindasitiri yekudzivirira mheni kubva payakatanga kuma1700.Muchokwadi, kunyangwe nanhasi, zvigadzirwa zvakajairika zviri kupihwa zvinongori zvidiki zvemheni zvechinyakare zvakabatanidzwa nemhasuru yewaya dzakafumurwa - tekinoroji yakatanga kubva kuma1800's.

1749 - Iyo Franklin Rod.Kuwanikwa kwemafambisirwo emagetsi emagetsi kunounza mupfungwa mufananidzo waBenjamin Franklin akamira mukutinhira akabata magumo ekiti uye akamirira kuti mheni irove.Nokuda kwe“kuedza kwake kuwana mheni kubva kumakore netsvimbo yakapinza,” Franklin akaitwa nhengo yehurumende yeRoyal Society muna 1753.Kwemakore mazhinji, kuchengetedzwa kwese kwemheni kwaisanganisira Franklin Rod yakagadzirirwa kukwezva mheni uye kutora mhosva pasi.Yakanga iine zvishoma inoshanda uye nhasi inoonekwa seyechinyakare.Ikozvino nzira iyi inowanzoonekwa seinogutsa kune maspires echechi, marefu maindasitiri chimneys uye shongwe umo nzvimbo dzinofanirwa kudzivirirwa dziri mukati mekoni.

1836 - Iyo Faraday Cage System.Yekutanga yekuvandudza kune mheni tsvimbo yaive Faraday cage.Iyi inzvimbo yakavharirwa inoumbwa nemambure ekuitisa zvinhu padenga rechivako.Yakatumidzwa zita remusayendisiti wechiRungu Michael Faraday, akaagadzira muna 1836, nzira iyi hainyatsogutsa nekuti inosiya nzvimbo dziri pakati pedenga pakati pemakondakita asina kudzivirirwa, kunze kwekunge dzadzivirirwa nemhepo dzemhepo kana matenga emadziro epamusoro.

• naFaraday System, dziviriro yemheni inoumbwa nematanda akawanda emheni, isingasviki tsoka imwe kumusoro, yakamisikidzwa pamapoinzi ese ari padenga.Dzinofanirwa kusunganidzwa pamwe chete nemakondukita edenga uye akawanda pasi makondakita kuti aite keji isingapfuuri 50 tsoka x 150 tsoka uye ine materminal emhepo pamharadzano yepakati pedenga remba.
  Chivako chinomiririrwa pano 150 ft. x 150 ft. x 100 ft. kureba.Nzira yeFaraday inodhura kuisa, inoda midziyo yakawanda pamusoro pedenga remba uye mapindiro akawanda edenga…asi kusvika pakati pemakore ekuma1900, pakanga pasina chiri nani.

• 1953 - The Preventor.Iyo Preventor ndeye ionizing air terminal iyo ine simba mukushanda.JB Szillard akatanga kuyedza maconductor ekuvhenekesa ionizing muFrance, uye muna 1931, Gustav Capart akapa patent yemuchina wakadaro.Muna 1953, mwanakomana waGustav Alphonse akavandudza chimurenga chababa vake, uye kugadzirwa kwake kwakaguma nezvatinoziva nhasi sePreventor.
  Iyo Preventor 2005 yakazogadziridzwa neHeary Brothers yeSpringville, New York.
  Vanodzivirira vane simba mukushanda, nepo, nzira dzekare dzakamira.Semuenzaniso, kana gore remhepo rinosvika kune chivako chakadzivirirwa, ion field yemagetsi pakati pegore nevhu inowedzera.Maion anogara achiyerera kubva payuniti, anotakura mamwe maion epasi akananga kugore, uye izvi zvine mhedzisiro yekudzikisa kwechinguva kusimba kweiyoni pakati pegore nevhu.Inofanira kunzwisiswa zvakajeka kuti haigoni kuderedza gore.Hazvina zvinopfuura kuderedza kushushikana kwenguva diki panguva iyo gore riri kupfuura pamusoro - asi uku kudzikiswa kwechinguvana kwemakakatanwa dzimwe nguva kunokwana kudzivirira kubuda kwemheni kubva.Nekune rimwe divi, kana uku kudzikisira kwekunetsana kusingakwane kudzivirira kukonzeresa, conductive ion streamer inopihwa kuti ibudise zvakachengeteka kupasi / pasi system.
  Heary Brothers yanga iri mubhizinesi kubvira 1895 uye ndiyo yakakura uye yekare inogadzira michina yekudzivirira mheni munyika.Ivo havangogadziri chete Preventor, asi zvakare vanovimbisa kuita kwayo.Chivimbiso chinotsigirwa nemiriyoni gumi yemadhora echigadzirwa inishuwarenzi.
