Kei a koe i mohio i te ao whakatairanga o te kōwhiringa hau? Kua kite koe i ngā take mō te mea ka rokohanga mai ngā rautaki nui i runga i ngā whenua, engari kāore koe i mōhio he mea atu anō e noho ana? Ko te whakaputa hau rere pūnaha vertikāti (VAWT). He mea tino whakarerekē te whakahaere o ngā whakaputa hau rere VAWT nui rawa atu i ngā huatau horizontāti i te mea e noho nei tonu nei.
Ko te mea hoki, he aha te wāhanga nui o ngā VAWTs? Ki te kōrero i ngā whēkau hū whenua turei, he kiko kōhatu kei raro i ēnei e pūnaha ana ki te rite ki te kaiwhiriwhiri pūroro waka, āe ko ngā VAWTs (pēnei i tēnei momo raraunga 3D) he kiko e huri ana i te take tuarua. Ki te iti me te pai rawa ake, ka ea te huringa hau mai i tētahi takiwā.
Heoi nei, i konei ka whakarongo tonu mātou ki te āheinga o enei rākau tuatahi hau. He wero iti noa iho! Ka horoia ngā raupo o te rākau hau e te hau. Ka whakaritea he ira māori e tetahi kaihokohoko, ka whakamahia inaianei ki te whakapāngia i ngā whare rānei, i ngā pouako.
Ka taea e ngā whakamahere VAWTs kia mahi pai i te wā e hīnātia ana ngā hīrahi whenua iti, ā, ka taea e ia te mahi i roto i ngā hau māhina noa iho, nō reira ka taea e ngā tuhinga matua e ai ki ngā hau nui. E mahi pai ana rātou i runga i ngā wāhi rerekē, in particular i roto i ngā wāhi paheke, kei reira ka pūmau ngā hīrahi whenua iti.
Ko te kōrero nei he whakarongo ki ngā pai o ngā motokore pūhau anake. Tuatahitia, ka noho rahi rawa atu rātou i ngā pūhau matua, nā te mea ka haere iti rawa ngā para o rātou, e whai ake nei i te wehewehe o ngā hīrea. Ka noho ora rawa atu hoki rātou mō ngā manu me ngā pekapeka, nā te mea ka kore e whakaputa i te hīnātanga "corkscrewing" e kitea ana e ngā huinga.
Nō reira, ka pai hoki ngā pūhau anake kia whakauru ki ngā wāhi iti, rānei ko ngā wāhi e take ana i te takoto i runga i ngā tahuhu whare rānei i roto i ngā whare, nā te mea ka taea e rātou kia whakauru i te hau e kore ana e hāngai ki te mua o te whare.
Ko te tīmata nei i te mea e hiahiatia ana ko te āhua o te whakaputa hau rere i runga i te pūnaha vertikāti, pūnui ki ngā wāhanga. E toru ngā wāhanga matua o enei; ko te rotor (e kawe ana ngā niho kaiwhiriwhiri, me te whakaputa motiti e huri i te kēmu ki te matepura), ko te pou tuara hei whakangungu i ngā hiranga, ko te rangitaki mōrearea e awhina ana ki te mahi pai me te pai o te whakahaere.
Ko ngā pūnaha hiko hau me ngā rākau te whāinga matua o tā mātou kaitāwhai hau ā-tīwhanui. Ka taea e mātou te whakaputanga i ngā whakauta ā-hāpua mō ngā kiritaki i te whakamāhi i ngā pūkenga o te whakahaere i te rārangi hāpai, i te wehenga o ngā whakauru. Ka tāwhai mātou i a koe i ngā ratonga pai tonu i ngā wā katoa o te rā mai i te whananga ki te whakamātautau, ki ngā mahi whakamutunga.
ko ngā hua matua ngā kaitāwhai hau, ngā pānā rākau, me ngā pākete riri lifepo4. Ka whiwhi ngā kiritaki i tēnei ratonga kotahi-kia-whakamātautau, i te whakauru, i te kaitāwhai hau ā-tīwhanui, i tēnei huinga hau-rākau, i ngā pūnaha rākau mātauranga. Ka whakaputanga a DHC i ngā hua, i ngā pūnaha, i ngā ratonga whakamutunga hei tautoko i ngā kiritaki, me ngā pūkenga pai o te whakamātautau.
Te pono te tuāpapa o tēnei kamupani. Tātou tuku ana i ngā whakamātautau pūmau hiko, i ngā ratonga pūkenga hoki. I te wā e whai ana i ngā turangawaewae hiko hau, ka taea e koe te mātua tono i ngā āhuatanga pērā i te roa o ngā parirau me ngā hau. Me mātua whai tonu i ngā āhuatanga pērā i te roa o ngā parirau me te taumaha. I tātou whakapā mai nei, ko ngā hua katoa o DHC he kōwhiringa turangawaewae hiko hau ā-pou tāwhai, me te whakamātautau hiko, kāore he whakamātautau hiko kua whakamāhinga.
Ko DHC te kaiwhakamātua i te pūnaha hiko wīra me te rā, ā, he whanonga ā-taumata tēnei. He whanonga ā-taumata a DHC e whakamahi ana i ōna whare ohaoha, ā, ko ngā mahi R&D, te whakamahinga, te whakamātautau, me ngā tautoko mātauranga kei rō ia. Mai i te tau 2009, kua tīmata ngā kaiwhakamātua o DHC ki te whakamāhi i te whakaaro mō te tiaki i te taiao, ā, kua whakamāhi hoki i ngā hanga houkore, ā, kua whakamāhi i te whanonga ā-taumata o ngā kōpae wīra tuakiri, e whai ana i te whakaaro "te whakamāhinga me te pono, te whakamāngō, me te whakamātauranga." Ko tēnei anō te take o tā mātou tohu: "DHC".
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.
