Ngā Pūrongo

I te marama o Hepetema kua taha ake nei, i pau i tētahi kaihokohoko koura o te Tāone o Niu Ioka te $72,000 ki tana moemoeā kino rawa atu: arā, ko ngā paoro koura rūpahu. Kei roto i ngā paoro koura rūpahu e whā, 10-aune te taumaha, ngā āhuatanga katoa o ngā paoro koura tūturu, tae atu ki ngā tau rangatū. He tino whakamataku tēnei ina whakaarohia te tokomaha o te hunga e pupuri ana i te koura—e whakaaro ana rānei kei a rātou te koura.
He kaiwhaiwhai ahau ki te koura rūpahu mai anō i te wā i tuhia ai tōku ingoa e te kaituhi a Damien Lewis i roto i tana pukapuka whakamataku tutei o te tau 2007, ko The Golden Cobra. He pakiwaitara noa iho taku wheako ki te hanga koura rūpahu, engari e kiia tonu ana ahau he puna kōrero mō tēnei kaupapa. I whakatau ahau kua tae ki te wā ki te whakapuaki i taku tinihanga me te hanga i ētahi pae koura rūpahu tūturu.
Engari i te whakarewa i ngā pae 10 auneke, i whakarewahia e au he tauira keke 2 kg (4.4 pauna), tata ki te rahi o te keke paparanga. He keke paparanga neke atu i te whā pauna te taumaha? Ae, he tino matotoru te koura, he matotoru ake i te mata. Me tika te taumaha o te mea rūpahu pai, me kotahi anake te huānga, he matotoru pērā i te koura, kāore i te irahiko, kāore hoki i te utu nui. Ko te tungsten tēnei, he iti iho i te $50 te utu mō ia pauna.
Hei waihanga i tētahi mahi rūpahu e whakaponohia ana, ka taea e ngā kaipahua te pani i te pūtake o te tungsten ki te koura rewa. He tata te taumaha o ngā pae koura, ā, i te wā e keri ana i ngā kōhao papaku, ko te koura tūturu anake ka kitea. Ko te pae koura e rua kirokaramu te rahi ka hokona mō te $15,000 pea, ā, ko te "utu" he $110,000 pea. Nā te mea me mahi au i roto i te tahua iti a PopSci, ā, ehara au i te tangata hara, i whakatau ahau ki te hanga i tētahi mea rūpahu me te $200 te uara o ngā rauemi.
I takaihia e au te pūtake o te tungsten ki roto i tētahi koranu mata me te antimony, he rite tonu te pakeke ki te koura. Pēnei, ka tika te ahua me te tangi ina pāngia, ina patohia. Kātahi ka pania e au te koranu ki te rau koura tūturu, ka hoatu ki ngā pae te tae me te kanapa motuhake.
Kāore taku mea rūpahu e roa te tinihanga i tetahi (ka taea e tō maikuku te rakuraku i te pepa koura), engari he ātaahua te āhua, he pai hoki te ahua, ahakoa te whakataurite ki taku pae koura totoka tūturu 3.5 aune. Ki taku whakaaro he pono.
