UKristof Retezar ngilethe okusha okusha. Le divayisi yenziwe ngokukhethekile ukuze ixhunywe ku-a i-bicicleta ivumela ukuguqula umswakama womoya ube ngamanzi okuphuza. Umshini ulula, umoya onomswakama ungena kudivayisi, bese upholile ngenxa yomphumela wePeltier onikezwa amandla elanga.
Ngemuva kwalokho yena umoya Idlulela ekamelweni eliphezulu lapho izinhlayiya zehlukaniswe emanzini nezindonga ezincane ezinezigqoko. Ekugcineni, amanzi ageleza ngeshubhu ukugcwalisa ibhodlela.
Ngosizo lwalokhu idivayisi, kungenzeka ukugcwalisa ibhodlela lamasentimitha angama-50 ngehora elilodwa nje. Noma kunjalo, amathuluzi asebenza ngokwengeziwe emanzi yiba yisikhathi.
Ingabe bewazi lokho umkhathi yakhiwe ngamathani ayizigidi eziyizinkulungwane eziyi-12 zamanzi nokuthi le nsiza ayixhashazwa? Le divayisi entsha izovumela ukusebenzisa le nsiza ngobuningi. Ngakho-ke, UKristof Phinda wenze kabusha wethule iphrojekthi yakhe ku James Dyson Imiklomelo. Into okufanele uyikhumbule ukuthi le divayisi isebenza kakhulu ekuhambeni okude nakwezinye izivakashi kude ne- izitolo ezinkulu, kusuka emithonjeni nasezindaweni lapho isebenza khona amanzi ahlanzekile.
