Imisipha yokwenziwa izonikeza amarobhothi amandla angaphezu kwawomuntu

Kamuva cwaningo eshicilelwe encwadini Isayensi, uprofesa wobunjiniyela bamakhompiyutha u-John Madden kanye nekhandidethi le-PhD u-Seyed Mohammad Mirvakili wase-University of British Columbia (UBC) bakhulume ngokudala imisipha yokwenziwa enamandla kusetshenziswa izintambo zokudoba kuphela. Ekanye nethimba labacwaningi bamazwe ngamazwe, uMadden noMirvakili baluka ngokuqinile imicu ye-polymer enamandla amakhulu eyenziwe nge-polyethylene nenayiloni ibe amakhoyili akwazi ukudonseka futhi aphumule.

Okwenza le misipha yokwenziwa iguquke kakhulu amandla ayo. UMadden utshele i-UBC ukuthi, “Mayelana namandla namandla emisipha yokwenziwa, sithole ukuthi ingakwazi ukuphakamisa izinsimbi ngokushesha izikhathi eziyi-100 esindayo kunomsipha womuntu wosayizi ofanayo, ekufinyezweni okukodwa. Iphinde ibe namandla okukhipha amandla aphezulu ngesisindo sayo ukwedlula awenjini evuthayo yemoto.”

Lokhu okutholakele kumelela igxathu elikhulu eliya phambili emzamweni wokuthuthukisa imisipha yokwenziwa eqinile nethembekile. Esikhathini esedlule, abacwaningi baseNyuvesi yaseTexas bazame okufanayo, kodwa ngezintambo ze-carbon nanotube. Izintambo ze-carbon nanotube azigcini nje ngokubiza kakhulu, kodwa futhi kunzima kakhulu ukusebenza nazo. Ngakolunye uhlangothi, umugqa wokudoba, ubiza cishe u-$5 ngekhilogremu futhi kulula kakhulu ukusebenza nawo.

Ukushintsha kwezinga lokushisa kubangela ukuthi imicu ifinyele futhi ikhululeke ngaleyo ndlela ibe namandla. Lokhu kushintsha kwezinga lokushisa kungenziwa ngezindlela eziningi, okuhlanganisa ukumuncwa kokukhanya noma ukusabela kwamakhemikhali kwamafutha. Ukubona lo mqondo usebenza, abacwaningi benza ividiyo yemisipha enika amandla ama-forcep okuhlinzwa.
