Cajin wayar dabi'a: Gidan wutar lantarki na gaba

E-Kaia cajar waya ce ta samfuri wacce ke amfani da kuzari mai yawa daga zagayowar photosynthesis na shuka da ƙananan ƙwayoyin cuta a cikin ƙasa don ƙirƙirar wutar lantarki. Evelyn Aravena, Camila Rupcich, da Carolina Guerro ne suka tsara E-Kaia a cikin 2009, ɗalibai daga Duoc UC, da Jami'ar Andrés Bello a Chile. E-Kaia yana aiki ta hanyar binne wani yanki na bio-circuit a cikin ƙasa kusa da shuka. 

Tsire-tsire suna ɗaukar iskar oxygen, kuma idan aka haɗa su da makamashi daga rana, suna tafiya ta hanyar tsarin rayuwa mai suna photosynthesis. Wannan sake zagayowar yana haifar da abinci ga shuka, wasu daga cikinsu ana adana su a cikin tushen su. A cikin tushen akwai ƙwayoyin cuta waɗanda ke taimaka wa shuka don ɗaukar abubuwan gina jiki kuma su sami abinci. Kwayoyin halitta suna amfani da wannan abincin don tsarin hawan jini na kansu. A cikin waɗannan zagayowar, abubuwan gina jiki suna canzawa zuwa makamashi kuma yayin aiwatarwa an rasa wasu electrons - suna shiga cikin ƙasa. Wadannan electrons ne na'urar E-Kaia ke amfani da su. Ba duk electrons ake girbe a cikin tsari ba, kuma shuka da ƙananan ƙwayoyin cuta ba su cutar da su a cikin tsarin ba. Mafi mahimmanci, irin wannan nau'in samar da makamashi, ko da yake ƙanana, ba shi da wani tasiri na muhalli saboda ba ya fitar da hayaki ko wasu abubuwa masu cutarwa kamar hanyoyin gargajiya.

Fitar E-Kaia shine 5 volts da 0.6 amps, wanda ya isa ya yi cajin wayarka cikin kusan awa ɗaya da rabi; don kwatantawa, fitarwar cajar USB na Apple shine 5 volts da 1 amp. Ana haɗa kebul na USB a cikin E-Kaia don haka yawancin caja na waya ko na'urorin da ke amfani da kebul na iya toshewa da caji bisa ga muhalli. Domin har yanzu takardar shaidar ƙungiyar tana nan, ba a samu takamaiman bayani game da E-Kaia bio-circuit ba, amma ƙungiyar na fatan za su iya fara rarraba na'urar daga baya a cikin 2015. 

Hakazalika, Jami'ar Wageningen a Netherlands suna haɓaka Shuka-e. Plant-e yana amfani da ka'ida iri ɗaya da E-Kaia inda electrons daga ƙananan ƙwayoyin cuta a cikin ƙasa ke ba da ƙarfin na'urar. Kamar yadda na'urar Plant-e ke da haƙƙin mallaka an fitar da cikakkun bayanai kan yadda yake aiki: An dasa wani anode a cikin ƙasa, kuma an sanya cathode da ke kewaye da ruwa kusa da ƙasan da membrane ya rabu. An haɗa anode da cathode zuwa na'urar ta wayoyi. Kamar yadda akwai bambanci tsakanin yanayin da anode da cathode ke ciki, electrons suna gudana daga ƙasa ta cikin anode da cathode kuma a cikin caja. Gudun wutar lantarki yana haifar da wutar lantarki kuma yana ba da ƙarfin na'urar.
