Dynamo: ekuguquleni namandla kagesi amandla amandla

Labo usamkhumbula iminyaka yakhe esikoleni, cishe, kodwa asikukhohlwanga umuzwa okuqondene isimangaliso encane ekhadini sifundo physics lapho uthisha wabonisa ngokucacile ukuguqulwa kwemisipha amandla komuntu ku ugesi. Thobekile ngobukhulu futhi sibonisa ugesi ngaphandle izintambo nezinyawo nebhethri ngenkathi ujikelezisa knob ovuthayo light isibani - futhi ngokushesha knob rotary, le licace ke uyaphakama.

Nokho, ukuze bazizwe bemangele, exovwe a zokungabaza enempilo: engu-ugesi, Izitolo cishe yonke indawo, kuze kushe izinhlanga ibhethri. Ngakho yini noma cha ukusebenza kwezandla nezinyawo zakhe, uma nanka - izithelo okwatholwa omkhulu?

Kodwa kufanele wenzenjani-ke, bedukile emini bese wathola ukuthi icala ku igajethi yakho ezintsha-fangled noma ngisho izingcingo ubudala yeselula zero ngokuphelele?

Umqondo, okuyinto vele uye waphenduka eminyakeni eyikhulu nengxenye, phakathi kwezinye izinto, eyaziwa kahle yilabo esemncane washayela imoto budedengu ezintweni zokuthutha ezimbili ezinamasondo. Ugesi esilula ibhayisikili eqoqwe ngokoqobo nedolo liboshelwe isondo, lusekelwa ngamandla oludlulele ukushova amandla light isibani flashlight, ukhanyisa indlela svechereet, umgwaqo.

Izinzuzo kokuvula Faraday baziswa futhi kwezempi. Eqinisweni, ibhethri empeleni sinenai kuphela uma nje has a kwenkokhelo. Ngachitha it, iphenduka ibe into esindayo engenamsebenzi, esikhundleni lapho kungcono ukuthatha eyodwa ngaphezulu zinc nezinhlamvu. Kudingeka amandla? Isotsha ngalolo? Ake cool kanje ukulawula generator ukuqinisekisa umsebenzi umsakazo. (Ngenxa yokuthi generator ethiwa abantu - "eyisosha motor".)

Eqinisweni, akukho okushintshile nge obhekwe ngobuchwepheshe. Amagajethi - zobuchwepheshe, futhi akukho ukunikezela amandla value abo ilingane no-zero, ikakhulukazi uma kungukuthi icala ngalolo esikhathini esizayo esiseduze. Inani solar panel nayo lost in sezulu uluvindi noma ebusuku. Dynamo kulesi sici ezingaphezu kuka intela. kwakukhona indoda, kugucula isibambo, futhi wamanje kuyoba!

Amaphayona kuleli cala, Yiqiniso, izingcweti ngubani zijwayele yokuthi cishe konke kuleli zwe, kuhlanganise ugesi, izandla okufanele kwenziwe. Autodidact ayizange ukuhlala ku exchange of impumelelo yabo, futhi ngenxa omagazini ezikhethekile egcwele izithombe nemidwebo amadivayisi elula, agcwalisiwe kalula Lantern amabhethri, omakhalekhukhwini, Smartphones, futhi GPS-amatilosi. Ungakhohlwa abathandi ibhayisikili ukuhamba: nje ohambweni olude - futhi "on-ebhodini" ugesi izonikeza ukushaja okugcwele iPhone noma aypada.

Ekugcineni, ngibona izinzuzo ngokoqobo ezibukwayo iminyaka nezinsiza esikoleni, kulandele abakhiqizi amateur nezobuchwepheshe some. Manje emakethe amadivayisi ngempela ephathekayo, kokunikezela umsebenzisi ukuguquka amandla kwemisipha ku ugesi cishe kunoma yisiphi electronics. Ngokwesibonelo, i-flashlight encane LED esifanelana entendeni yesandla sakho, has a isibambo ensikeni. Engingakusho nje ngoba twist ngomzuzu ke ngesivinini rotations ezimbili ngomzuzwana ukuba imizuzu embalwa kudivayisi inkanyiso.

ujabula kakhulu yokuthi, ngokulinganisa nale imishini uthengiswa wokuphehla ugesi, eziklanyelwe intsha abanesifiso isayensi. Bangaphezi ukuzama ekhaya, awukwazi kuphela baqonde indlela ukuze uthole ugesi ehlanzekile ngaphandle amabhethri nama-accumulator, kodwa futhi baziqambela into entsha ...
