Dynamo tshuab: lub transformation ntawm lub zog ntawm lub zog mus rau hauv lub zog ntawm hluav taws xob

Cov neeg uas tseem nco ntsoov nws lub tsev kawm ntawv xyoo, tej zaum, tsis nco qab lawm tus lawm ntawm teej tug mus rau ib tug me me txuj ci tseem ceeb nyob rau hauv ib tug physics zaj lus qhia qhov twg tus xib fwb kom meej meej pom lub hloov dua siab tshiab ntawm nqaij ib tug neeg lub zog mus rau hauv hluav taws xob. Txaus siab rau qhov loj thiab muaj peev xwm, ib qho dynamo tsis muaj xov nyob nrog cov ntsaws thiab cov roj teeb nrog txoj kev sib hloov ntawm qhov kov teeb lub qhov muag teeb - thiab ceev tus cwj mem tau tig, qhov ci nws hlawv.

Mus rau qhov zoo ntawm qhov txuj ci tseem ceeb, txawm li cas los xij, muaj kev tsis sib haum xeeb tau sib txuas nrog: ib tiam dhau los ntawm hluav taws xob, rosettes yuav luag txhua kauj ruam, roj teeb uas tau teem tseg. Yog li ntawd, nws tsim nyog ua haujlwm nrog koj ob txhais tes thiab ko taw, yog tias lawv yog cov txiv hmab txiv ntoo ntawm cov discoveries zoo?

Tab sis koj ua dab tsi, kom poob lawm nyob rau hauv broad daylight thiab pom hais tias tus nqi rau koj cov tshiab-fangled gadget los yog txawm ib tug laus mobile xov tooj ntawm tsis pes tsawg?

Muaj ib lub tswv yim uas twb tau ua kev zoo siab rau ntau tshaj li ib xyoos thiab ib nrab, thiab lwm yam, cov neeg uas, raws li ib tug me nyuam, tau tsav lawv tus kheej nyob rau hauv ib lub tsheb uas muaj ob-wheeled heev. Qhov yooj yim dynamo-tsheb rau ib lub tsheb kauj vab, sib sau ua ke nyob rau ntawm lub hauv caug thiab tsau rau pem hauv ntej lub log, pub los ntawm lub zog dawb ntawm lub rotation ntawm pedals ib lub teeb teeb uas illuminated txoj kev nws gleamed.

Qhov zoo ntawm Faraday's discovery kuj yog ris txiaj ntsig los ntawm cov tub rog. Qhov tseeb, lub roj teeb muaj nuj nqis, tsuas yog thaum nws muaj tus nqi. Thaum siv nws, nws hloov mus rau hauv ib qho khoom siv hnyav khoom, tsis yog qhov uas nws yog qhov zoo dua rau noj lwm zinc nrog cartridges. Xav tau lub zog? Ib tug tub rog ua li cas? Cia nws twist, raws li nws yuav tsum, tus kov ntawm lub tshuab hluav taws xob kom ua hauj lwm ntawm tus walkie-talkie. (Tias yog vim li cas cov generator tau nicknamed lub "tub rog-cav" ntawm cov neeg.)

Nyob rau hauv tus, me ntsis tau hloov thiab nrog qhov pib ntawm lub era ntawm high technology. Gadgets yog gadgets, thiab tsis muaj fais fab, lawv cov nqi qis, tshwj xeeb tshaj yog tias lawv tsis them nyiaj rau yav tom ntej. Tus nqi ntawm solar panels yog tseem poob nyob rau hauv cov pos huab huab cua los yog thaum hmo ntuj. Cov paj nyob rau hauv no yog ntau tshaj li unpretentious. Yuav muaj ib tug txiv neej uas muaj peev xwm sib ntswg cwj mem, tab sis yuav muaj tam sim no!

Cov tho kev hauv cov xwm txheej no, tau muaj cov neeg ua haujlwm, siv rau txhua yam hauv lub ntiaj teb no, nrog rau kev ua neej, yuav tsum yog yus tus kheej. Cov neeg qhia nws tus kheej tsis tau paub txog qhov lawv ua tau zoo, thiab yog vim li ntawd, cov ntawv xov xwm tshwj xeeb muaj cov duab thiab kos duab ntawm cov khoom siv yooj yim uas rov qab tau roj teeb ntawm lub teeb nyem, xov tooj ntawm tes, smartphones thiab GPS navigators. Tsis txhob hnov qab cov kiv cua ntawm kev caij tsheb kauj vab: ib qho chaw txaus mus ntev - thiab "on-board" dynamo yuav muab tus nqi them tag nrho ntawm iPhone lossis iPad.

Thaum kawg, pom cov txiaj ntsim ntawm kev siv cov kev pab cuam ntawm cov xyoo kawm ntawv, cov kws tshaj lij tau koom nrog cov amateur. Tam sim no txoj kev ua lag luam muaj cov khoom siv hluav taws xob txaus kom muaj kev sib hloov ntawm cov leeg nqaij ntawm cov neeg siv ua hluav taws xob tam sim no rau txhua yam khoom siv hluav taws xob. Piv txwv, lub teeb nyem me me, fits nyob rau hauv xib-teg ntawm koj txhais tes, muaj ib tus ntiv tes folding. Nws yog txaus rau ib feeb kom tig los ntawm kev ceev ceev ntawm ob qho kev ua si thib ob, yog li ntawd lub cuab yeej yuav ci rau ob peb feeb.

Nws yog kev txhawb zog siab uas siv cov tshuab ua paj nruag los ua ke nrog cov khoom siv no, tshwj xeeb tshaj yog tsim los rau cov hluas xav kawm. Los ntawm qhov kawg ntawm kev sim hauv tsev, koj tsis tuaj yeem nkag siab tias yuav ua li cas thiaj li tau hluav taws xob tsis muaj roj teeb thiab accumulators, tab sis kuj yuav tsim ib yam tshiab ...
