Kwekwe Poly un­veils geyser in­no­va­tion

Chronicle (Zimbabwe) - - Business Chronicle - Love­more Zi­gara Mid­lands Cor­re­spon­dent

STU­DENTS in the elec­tri­cal en­gi­neer­ing depart­ment at Kwekwe Polytechic Col­lege have come up with a new wa­ter geyser sys­tem in­no­va­tion, which saves power by up to 50 per­cent.

It heats wa­ter us­ing dif­fer­ent com­bi­na­tions of en­ergy, which are so­lar, elec­tri­cal en­ergy and the mi­crowave sys­tem, which heats wa­ter at dif­fer­ent stages.

The in­no­va­tion at­tracted a lot of at­ten­tion at the just-ended Mid­lands Agri­cul­tural Show where the col­lege was ex­hibit­ing.

Mercy Mu­tambo, an elec­tri­cal en­gi­neer­ing stu­dent at the col­lege said they were work­ing on per­fect­ing the in­no­va­tion so that the geyser saves power by up to 75 per­cent.

“This is a mi­cro con­troller based hy­brid wa­ter heater and in this heater there are three en­ergy lev­els that are be­ing used namely so­lar, mi­crowave and the nor­mal geyser sys­tem that we know. The so­lar sys­tem raises tem­per­a­ture to 40 de­grees Cel­sius and then it goes to the nor­mal geyser sys­tem that we know and raises the tem­per­a­ture to 45 de­grees Cel­sius and the mi­crowave will raise the wa­ter to up to 65 de­grees Cel­sius,” she said.

“This in­no­va­tion was done to prove that en­ergy can be con­served if you use the hy­brid sys­tem rather than the sin­gle pow­er­ing sys­tem and this is a pro­to­type.

‘‘In this de­sign it has been proven that it re­duces power con­sump­tion by 50 per­cent but there are fur­ther pos­si­bil­i­ties of it ac­tu­ally go­ing higher in terms of en­ergy sav­ing of up to 75 per­cent.”

The in­no­va­tion by the col­lege comes as the coun­try is try­ing to come up with strate­gies to save power in light of the pre­vail­ing elec­tric­ity short­ages.

The Gov­ern­ment has al­ready moved to ban the use of elec­tric gey­sers and switch­ing to so­lar-pow­ered wa­ter heaters in a move aimed at sav­ing up to 400 megawatts of elec­tric­ity.— @lavuzi­gara1.
