IHelioRec (www.heliorec.com) yinkampani yezobuchwepheshe obuluhlaza egxile emandleni elanga nasekuvuseleleni kabusha amapulasitiki asekhaya nawezimboni. Ukulandela imigomo nemibono yayo, iHelioRec isungule uhlelo lokukhiqiza amandla elanga oluzothola ngempumelelo ukusetshenziswa kwalo emazweni:
- Ngenqwaba yemfucuza yepulasitiki engachazwanga;
- Ngabantu abaningi;
- Ngokushoda kweminye imithombo yamandla.
Umqondo oyinhloko wephrojekthi uqukethe izigaba ezintathu
- Ukwakhiwa kwamapulatifomu antantayo avela kudoti wepulasitiki osetshenzisiwe kabusha, i-high density polyethylene (HPPE). I-HPPE ingatholakala kumapayipi epulasitiki, iziqukathi, ukufakwa kwamakhemikhali asendlini, izitsha, njll.
- Ukufakwa kwamapaneli elanga kuzingxenyekazi;
- Ukufakwa kwamapulatifomu olwandle eduze kwamachweba, izindawo ezikude, iziqhingi, amapulazi ezinhlanzi.
Izinhloso eziyinhloko zephrojekthi
- Ukusetshenziswa okunengqondo kwepulasitiki eyenziwe kabusha ekukhiqizeni amapulatifomu antantayo;
- Ukusetshenziswa kwamanzi emazweni anabantu abaningi;
- Ukukhiqizwa kwamandla elanga anemvelo.
Ithimba le-HelioRec liqinisekile ngokuqinile ukuthi ukunakwa komhlaba wonke kufanele kudonselwe emazweni ase-Asia. Amazwe akulesi sifunda enza umnikelo omkhulu kunayo yonke ekwakhiweni kwezinkinga zemvelo zomhlaba, njengokufudumala kwembulunga yonke, umphumela wokushisa komhlaba, ukungcoliswa kwemvelo ngepulasitiki engacaciswanga.
Nawa amaqiniso ambalwa azikhulumela wona. Sekukonke, i-Asia ikhiqiza u-57% wokukhishwa kwe-CO2 emhlabeni, kuyilapho iYurophu ikhiqiza kuphela i-7% (Umfanekiso 1).
Umdwebo 1: Izibalo zokukhishwa kwe-Global CO2
I-China ikhiqiza u-30% wepulasitiki womhlaba, kepha okwamanje ngu-5-7% kuphela osetshenziswayo kabusha, futhi uma kulandelwa lo mkhuba, ngo-2050 kuzoba nepulasitiki eningi kunezinhlanzi ezilwandle.
Idizayini yengxenyekazi
Ukwakheka kwepulatifomu entantayo kuzoba ngamapaneli wesangweji, into esemqoka ekukhiqizweni okuzokwenziwa kabusha kwepulasitiki, i-HPPE. Umjikelezo wepulatifomu uzoqiniswa ngezinto eziqinile ezifana nensimbi ukumelana nokucindezela kwemishini. Amasilinda angenalutho enziwe ngekhwalithi ephezulu nezinto zokwakha zepulasitiki azonamathiselwa ezansi kwepulatifomu entantayo, ezosebenza njengesiqhoqhoqho semithwalo emikhulu ye-hydromechanical. Ingaphezulu yalawa masilinda izogcwala umoya ukugcina ipulatifomu iqhubeka. Lo mklamo ugwema ukuthintana ngqo kwepulatifomu nemvelo ebhubhisayo yamanzi olwandle. Lo mqondo wahlongozwa yinkampani yase-Austrian HELIOFLOAT (www.heliofloat.com) (Umdwebo 2).
Umdwebo 2: I-Hollow Cylinder Floating Platform Design (Ngokuzithandela kwe-HELIOFLOAT)
Lapho ukwakhiwa kwepulatifomu sekuphothuliwe, ikhebula lomkhumbi wamanzi olwandle nezintambo okusetshenzwa kulengwa kuzozokwenzelwa indawo ngayinye. Inkampani yasePortugal iWavEC (www.wavec.org) izokwenza lo msebenzi. I-WavEC ingumholi emhlabeni ekusetshenzisweni kwamanye amaphrojekthi kagesi olwandle (Umdwebo 3).
Umdwebo 3: Ukubalwa kwemithwalo ye-hydrodynamic kuhlelo lweSesam
Iphrojekthi yokulinga izofakwa ethekwini laseYantai, eChina ngosizo lweCIMC-Raffles (www.cimc-raffles.com).
Okulandelayo
IHelioRec yiphrojekthi eyingqayizivele ezophinde yenze imisebenzi eyengeziwe maduze nje:
- Ukuqaphela umphakathi ngezinkinga zokungcola kwepulasitiki;
- Izinguquko emqondweni wabantu maqondana nokusetshenziswa (izinsiza kanye nempahla);
- Ukunxenxa imithetho yokweseka eminye imithombo yamandla nokuvuselelwa kwepulasitiki;
- Ukusebenziseka kahle kokuhlukaniswa nokucutshungulwa kwemfucumfucu yemfucumfucu kuwo wonke amakhaya, kuwo wonke amazwe.
