Zvirimwa ishamwari huru yevanhu uye yakakosha mukurwisa kushanduka kwemamiriro ekunze.Dzinosveta carbon dioxide dzoishandura kuva mhepo inotsamira pairi vanhu.Kuwanda kwemiti yatinodyara kunoita kuti kupisa kushoma kunopinda mumhepo.Asi zvinosuwisa, nekuda kwekuparadzwa kusingaperi kwezvakatipoteredza, zvidyarwa zvine ivhu shoma uye shoma uye mvura yekurarama pairi, uye isu tinoda kwazvo "mubatsiri mutsva" kubatsira kudzikisa kabhoni.
Nhasi ndinopa kwauri chigadzirwa chekugadzira photosynthesis - the"artificial tree", rakabudiswa nefizikiki Matthias May weHZB Institute for Solar Fuels muBerlin mumagazini "Earth System Dynamics yakabudiswa mumagazini "Earth System Dynamics".
Chidzidzo chitsva ichi chinoratidza kuti artificial photosynthesis inotevedzera maitiro ayo zvisikwa zvinopa mafuta ezvirimwa.Kufanana nephotosynthesis chaiyo, nzira yacho inoshandisa carbon dioxide nemvura sechikafu, uye chiedza chezuva sesimba.Musiyano bedzi ndewokuti panzvimbo pokushandura kabhoni dhaikisaidhi nemvura kuva zvinhu zvakasiana-siana, inobudisa zvinhu zvine carbon-rich, zvakadai sedoro.Maitiro acho anoshandisa sero rezuva rinokosha rinotora chiedza chezuva uye rinoendesa magetsi kune dziva re carbon dioxide yakanyungudutswa mumvura.A catalyst inomutsa kuita kwekemikari inoburitsa oxygen uye carbon-based byproducts.
Muti wekugadzira, sekushandiswa kumunda weoiri wapera, unoburitsa okisijeni mumhepo kungofanana nechirimwa photosynthesis, nepo imwe kabhoni-based byproduct inotorwa nekuchengetwa.Nechinoti, artificial photosynthesis yakaratidzwa kuva inoshanda zvakanyanya kupfuura Natural photosynthesis, mutsauko mukuru uri wekuti miti yekugadzira inoshandisa zvinhu zvekugadzira inorganic, izvo zvaizowedzera zvakanyanya kutendeuka kugona.Uku kushanda kwepamusoro kwakaratidzwa mukuedza kukwanisa kushanda zvakanyanya munzvimbo dzakaoma pasi pano.Tinogona kuisa miti yakagadzirwa mumagwenga pasina miti uye pasina mapurazi, uye kuburikidza nekugadzirwa kwemiti yemiti tinogona kutora yakawanda CO2.
Kusvika pari zvino, iyi tekinoroji yemiti yekugadzira ichiri kudhura, uye kuoma kwehunyanzvi kuri mukugadzira zvakachipa, zvinogoneka zvinokonzeresa uye anogara ezuva maseru.Munguva yekuedza, kana mafuta ezuva anopiswa, yakawanda kabhoni yakachengetwa mairi inodzorerwa kumhepo.Naizvozvo, tekinoroji haisati yakwana.Parizvino, kumisa kushandiswa kwemafuta ezvicherwa inoramba iri nzira yakachipa uye inoshanda kwazvo yekudzora shanduko yemamiriro ekunze.
