Ko te momo mōtini o te tūru wīra hiko he mea nui hei whakatau i tōna kaha, i ngā whakaritenga tiaki, me te wheako kaiwhakamahi. I tēnei wā, ko ngā kōwhiringa matua ko ngā mōtini paraihe me ngā mōtini kore paraihe, he rerekē rawa ngā mātāpono hangarau me ngā āhuatanga tono.

Ngā Mōta Paraihe: Hangarau Pakeke, Kaha te Urutau

Ka whakamahia e ngā mōtini paraihe te pa atu o ngā paraihe me te commutator hei kawe i te iahiko me te huri i te ahunga. He hangarau taraiwa kua whakamātauhia. He kaha te taipana tīmatanga, ā, he tino pai mō ngā whenua uaua me ngā pari e neke atu ana i te 8°. E whakaatu ana ngā whakamātautau parae, i te kaha ōrite, ko te tere urupare tuatahi o ngā mōtini paraihe i te wā e piki ana he tata ki te 0.3 hēkona te tere ake i tō ngā mōtini kore paraihe.

Heoi, he wāhanga pau noa ngā paraihe, ā, me whakakapi i muri i ngā mano ki te tekau mano hāora o te mahi. I roto i ngā taiao kino pērā i te haumākū me te puehu, ka piki ake te pakaru o te paraihe mā te 30%. Ko te tiaki auau ko te whakakapi paraihe (tata ki te $5 te utu mō ia mahi) me te horoi i ngā putunga waro. He iti te ārai hangarau o ēnei motuka, ā, he ngāwari te whakatika, he mea tino pai mō ngā wāhi he iti te tautoko hangarau.

E rua ngā āhuatanga e whakamahia ana i tēnei wā, arā, ko ngā kaupapa hokohoko a te kāwanatanga i ngā rohe maunga (pērā i te Tonga-mā-rāwhiti o Āhia me Amerika Latina), nā te mea he pai te urutau ki ngā pari me te ngāwari o te tiaki; tuarua, ko ngā rohe makariri (pērā i te Raki o Ūropi), ka taea te pupuri i te tīmatanga noa i ngā pāmahana iti iho i te -40°C.

Ngā Mōta Kore Paraihe: He Pai Rawa, He Haruru Iti, He Pūmautanga Mō Te Wā Roa

Ka whakamahia e ngā mōtini kore-paraihe ngā pūmana hiko mō te whakawhiti, ka whakakorea ngā wāhanga e pā ana ki te tinana, ā, ka whakanuia te pai o te hurihanga mana ki te neke atu i te 85%. Mē te kaha pākahiko ōrite, ka taea e rātou te whakatutuki i te whānuitanga roa ake o te 15%-20% i ngā mōtini paraihe.

Nā te hoahoa kore-waku, ko te whakahinuhinu o te peera e hiahiatia ana i ia rua tau, ā, ko te roa o te ora o te waka he neke atu i te 20,000 hāora. Heoi, he nui ngā utu tiaki i te kaiwhakahaere, tata ki te 15% o te uara o te waka. Kia mōhio koe, i ngā taiao pāmahana teitei (hei tauira, neke atu i te 50°C), ka pā pea te tiaki wera nui ki te mahi.

Ka mahi te mōta kore paraihe i raro i te 45 tetere, ā, he tino pai mō ngā wāhi he tino kaha ngā whakaritenga whakahaere haruru, pērā i ngā whare tiaki kaumātua papai i Ūropi me te Hononga o Amerika. E whakamahia whānuitia ana hoki i roto i ngā mākete ratonga reti pērā i ngā taunga rererangi me ngā hōtēra, ā, ka āwhina tōna pono ki te whakaiti i ngā utu whakahaere. Hei tāpiri, ka penapenahia e tōna mama ngā utu tāpiri mō ngā kaiwhakamahi e takiuru pinepine ana i ā rātou tueke mā runga rererangi.
