Te Whakamārama Tamariki ki ngā Pūkaha Hau Kaitohutohu Take ki Runga
Kei te whakaaro koe i ahea koe i kite i runga i te rangi i tetahi piu hau? He whare tu tonu nui me ngā raunga roa e whiria ana i te hau, penei i te kowhaiwhai e whiriwhiri ana i te hau i te wa o te hāpai. Engari, kei te mohio koe i te mea he momo tuatahi rānei o ngā piu hau? Ko te tu tuatahi ko te Piukaha Taurangi Tu Vertikāru ki tōna ingoa pūmau, arā ko te VAWT. Ki ngā wā e kore e noho pū te VAWT hei whiria i te hau pērā i te purerehua, he iti rawa ākea ā-mua ā-roto ā-roto i ngā raunga iti nei e whiria ana i runga i tētahi takirua tu vertikāru, paihīria penei i a koe e whiti ana pērā i te karawhiu.
He aha te take i whiriwhiri ai tētahi i te VAWT i runga i te turbine hau hauhau o te tuaka whakapae (HAWT) tuku iho. Hei tīmatanga, ka taea e ngā VAWT te mahi i roto i tētahi aronga hau (he rerekē ki ngā HAWT e tohu ana ki te hau hei mahi), ā, ka pai ake te whakamahi i ngā hau hauhau. I roto i te mahi, ko te tikanga ka taea te whakatakoto i nga VAWT ki te taha tata, e whakaora ana i te wāhi, e whakapiki ake ana i te kaha. Ko tētahi atu mea whakamīharo mō ngā VAWT, he tino hū, he iti rawa hoki te ngaru, ā, ka whai hua ki ngā whare taone.
Ko tenei e whakaaro ana koe kei te aha te pai rawa turangawaewae — ko te VAWT ranei, ko te HAWT ranei? Noho au ki te whakaaro, ka hiki i te take nui.... Nga HAWT he manu whakamau tonu mo nga whenua nui o nga marae pu: ka mahi noa i te mea i tautoko ai to tatou kaiako Pūhanga, ka puta he spin waenganui no te mea ka noho kotahi te hunga nei. Na runga i reira, e pai ana nga VAWT i nga wahi e iti ana te whenua, heoi ano e kore e tika ana te huarere. E hia noa iho hoki nga VAWT i te ara matatika mo etahi, no te mea ka noho hei katoa mea atu, ka pai rawa ki te kitea i te tuatahi, i te tuarua i te HAWT.
Ēnā, i te mea ko te huringa āhuarangi e whakawhai ake ana i tō mātou whakamahi ki ngā puna waihanga aniwaniwa, ka nui ake tonu ngā whakatangitanga i te hunga kairangahau me ngā kaihanga i te whakahoutanga VAWT. He mea nui rawa te whakaaro o ngā VAWT e taea ana ki te pūmau i raro i te moana, e tino whai hua ana mō ngā pa tuhonotahi i runga i te moana. Ngarongarongo anō, e āhei ana ngā turbinī i raro i te moana kia hoko i te waihanga mai i ngā hūhā hau me ngā hau o te moana hei whakaputu i te hiko - he mahi kāore i kitea mō ngā hau whenua whānuitia i roto i ngā wai ohooho.
Ko ngā Turbine Hau Pūtahi Kapa Tūranga i whakaritea tonu i ake i te kaupeka rau tau, engari inaianei ka whakaaro mōhio he tūtohu hei whakamahi i te waiora. I mua atu i waenga o ngā rau tau mano, i te ao kohikohi o te Peresia i mua, ka hanga i ngā toki hau kapakapa kapa tūranga hei kaihono whenua (āe me te whakawāhi wai hoki). Ki te iti nei, ka nui ake ngā whakatihonutanga ki ngā VAWT, ka noho pai ake ngā whakatū hou hei hoko i te waihanga waiora i aua take katoa i te maha o ngā toki hau i mua. Ka tae ki te tau 21, ko te VociWind i whakaaetia he whare wāhi pai.
Kei te tuhinga i te whakamārama mō ngā Pūkaha Hau Kaitohutohu Take ki runga, he ara hou me te wana ake hei whakapuaki i te kaiwhakaora whenua. Ki āhea, e kore ana rātou i te mohio tonu rānei, i ngā pūkaha hau nui o mua, he momo huarahi ōrite kei a ngā pūkaha take kaitohutohu, ka whai ake i ā rātou pai, ka whakapakariina hoki i a rātou hei tirohanga i ngā hiahia o tō tātou taiao e tahuri nei. Nā reira, i te wa e kite ana koe i tētahi pūkaha hau, kaua e whakawā iho ki te mōhio — ehara i te mea iti, ka āhei pea ko te VAWT (Pūkaha Hau Take Kaitohutohu) e noho tū tonu ana ki runga i te hau e takahi nei!
Ko ā mātou hua matua ko ngā turbīn hau me ngā pānā pūhāpū. Ka taea e mātou te whakapānui i ngā kiritaki i ngā ratonga katoa-i-tahi mō ngā whakamātautau pūhāpū mātauranga, i ngā whakamātautau hau-pūhāpū huinga hoki. Ko DHC he kaiwhakamātua pūmau o ngā hua, o ngā whaihanga, o ngā ratonga whakamātau i muri i te hoko, o ngā turbīn hau āki tū ihi.
Ko te kaiarahi i te kāwanatanga o ngā rangahau pūnaha rāngi me te rā, ko DHC. He nohonga hanga hei whakauru i ngā mahi rangahau me te hanga, me te hanga pūnaha me te tautoko pūtaiao. I te tau 2009, i whakapūmaia e ngā kaitūhono o te DHC te whakaaro tirotiro i te taiao, ā, i noho i te hunga rorohiko hou me te whakanui i te tikanga "whakangungu me te paihere, whakatoi me te hōtuhi." Ko tēnei hoki te tuhitika o tō tātou tohu "DHC".
Ko tā mātou whakamātautau he whakamātautau i ngā hāngā hiko tauhokohoko me ngā hāngā kāinga mā te whakamātautau hau/pūhāpū. I tēnei wā, i tā mātou whakamātautau i ngā hāngā whakamātautau hau āki tū ihi, ka taea e mātou te whakapānui i ngā kiritaki i ngā whakamātautau katoa. Me mātou anō te mātau i ōu hāngā, mai i te whakamātautau, mai i te whanonga, ki ngā ratonga whakamātau i muri i te hoko; ka taea e mātou te whakapānui i a koe i ngā whakamātautau mātauranga i tēnei wā, i tēnei wā.
Ko tā mātou whakamātautau i te pono hei tuāpapa o tā mātou pakihi. Ka tuku mātou i ngā hua hiko pai rawa atu ki ngā kiritaki, ā, i ngā ratonga pūkenga hoki. Mō ngā tāwhiri hiko wao, he mea nui te whakamātautau i te pono hei tuāpā o tā mātou pakihi, me te tuku i ngā hua hiko tāwhiri hiko wao tū ake, me ngā ratonga pūkenga. Me whakaaro koe i ngā rārangi pēnei i te roa o ngā parirau me te pākā o ngā tāwhiri hiko i te whakamātautau i ngā tāwhiri hiko. I tā mātou tāpaetanga, ko ngā hua katoa o DHC e whakamāhi ana i ngā hua hiko tika, kāore he whakamāhinga o ngā hua hiko.
Nau mai ki DHC, te tohu tuatahi mō ngā rangapū hau rā whakamahia! Tēnā tā matou mahi hei whakamārama i ngā whakaaetanga hou me ngā pūtake hou, ā, ina whai kē, he pūhanga hau, he pāne tāwhiti, he pouaka lifepo4, ānei.
