The eke ekwentị chaja: Ike osisi nke n'ọdịnihu

E-Kaia bụ chaja ekwentị ihe atụ nke na-eji ike karịrị ike sitere na okirikiri fotosynthetic nke osisi na microorganisms dị n'ime ala iji mepụta ọkụ eletrik. Emebere E-Kaia site na Evelyn Aravena, Camila Rupcich, na Carolina Guerro na 2009, ụmụ akwụkwọ sitere na Duoc UC, na Mahadum Andrés Bello dị na Chile. E-Kaia na-arụ ọrụ site n'ibe akụkụ bio-circuit n'ime ala dị n'akụkụ osisi. 

Osisi na-ebuba ikuku oxygen, ma e jikọta ya na ike sitere na anyanwụ, ha na-aga n'usoro usoro metabolic nke a na-akpọ photosynthesis. Usoro a na-emepụta nri maka osisi, ụfọdụ n'ime ha na-echekwa na mgbọrọgwụ ha. N'ime mgbọrọgwụ ya, e nwere microorganisms ndị na-enyere osisi ahụ aka inweta ihe oriri na-edozi ahụ ma na-enweta nri. Ihe microorganisms na-eji nri ahụ eme ihe maka usoro metabolic nke ha. N'ime okirikiri ndị a, a na-atụgharị nri na-edozi ahụ ka ọ bụrụ ike na n'oge usoro a na-efunahụ ụfọdụ electrons - na-abanye n'ime ala. Ọ bụ elektrọn ndị a ka ngwaọrụ E-Kaia na-eji. Ọ bụghị elektrọn niile ka a na-egbute na usoro a, a naghị emerụ osisi ahụ na microorganisms ya na usoro ahụ. Nke kachasị mma, ụdị ike ike a, ọ bụ ezie na ọ dị ntakịrị, enweghị mmetụta gburugburu ebe obibi ka ọ na-ahapụ ihe ọ bụla na-emepụta ihe ma ọ bụ ihe ndị na-emerụ ahụ dị ka ụzọ omenala.

Ihe mmepụta E-Kaia bụ 5 volts na 0.6 amps, nke zuru ezu iji chaja ekwentị gị n'ime ihe dịka otu awa na ọkara; maka ntụnyere, mmepụta chaja USB nke Apple bụ 5 volts na 1 amp. A na-etinye nkwụnye USB n'ime E-Kaia nke mere na ọtụtụ chaja ekwentị ma ọ bụ ngwaọrụ ndị na-eji USB nwere ike itinye ma kwụọ ụgwọ site na gburugburu ebe obibi. N'ihi na patent otu ahụ ka na-echere, nkọwapụta na E-Kaia bio-circuit adịbeghị, mana ndị otu ahụ nwere olile anya na ha nwere ike ịmalite ikesa ngwaọrụ ahụ ma emechaa na 2015. 

N'otu aka ahụ, Mahadum Wageningen na Netherlands na-emepe emepe Osisi-e. Plant-e na-eji otu ụkpụrụ dị ka E-Kaia ebe eletrọn si microorganisms na ala ike ngwaọrụ. Dị ka ngwaọrụ Plant-e nwere patent ewepụtala nkọwa na otú o si arụ ọrụ: A na-akụnye anode n'ime ala, a na-etinyekwa cathode nke mmiri gbara ya gburugburu n'akụkụ ala nke akpụkpọ ahụ kewara. A na-ejikọta anode na cathode na ngwaọrụ site na wires. Dị ka e nwere ihe dị iche ụgwọ n'etiti gburugburu ebe obibi nke anode na cathode dị, electrons na-esi na ala na-esi na anode na cathode na-abanye na chaja. Ntugharị nke eletrọn na-ebute ọkụ eletrik ma na-enye ngwaọrụ ahụ ike.
