Mana Atamai: Ka whakarerekē aunoa ngā pūoko hanganga hau whakauru i ngā tawhā (hei tauira, ngā paepae pāmahana, ngā tere whakahinuhinu) hei ārai i ngā hapa i puta mai i ngā huringa ohorere o te āhuatanga hau.
3. Te Whai Hua o te Huringa Ora
Hoahoa Tiaki Iti: Ka roa ake te roa o te ora o ngā wāhanga matua mā te >50% (hei tauira, ngā wā tiaki i te porowhita crankshaft 100,000-haora), ka whakaiti i te wā kore mahi i roto i ngā taiao morearea.
Arotau Pūngao: Ko ngā ānau kōpeketanga i whakaritea ki ngā tohu adiabatic motuhake-hau (ngā uara-k) ka eke ki te penapena pūngao 15%–30% ki te whakataurite ki ngā tauira tuku iho. Ko ētahi tauira ko:
