Faatasi ai ma le televave o le atinaʻeina o vailaʻau faʻava-o-malo ma le malosi o loʻo faʻaaogaina, o tane ma pusa e teu ai uamea e masani ona faʻaaogaina i le felauaiga ma le teuina o vailaʻau, meaʻai ma meainu, malosi ma isi mea.Ona o lona malosi sili ona maualalo le vevela ma le lelei o le pala, o le austenitic stainless steel e masani ona faʻaaogaina i le fausiaina o tane teuina cryogenic, meafaigaluega ma fausaga cryogenic tetele.

Ina ia mafai ona faʻamalieina le manaʻoga maketi, ua atiaʻe e le matou kamupani le tele o le vevela o le vevela, maualuga le malosi austenitic stainless steel electrodes, le vailaʻau vailaʻau o le uʻamea teuina (e pei ona faʻaalia i le Laulau 1) ma mea faʻainisinia mautu (e pei ona faʻaalia i le Laulau. 2), ma e sili ona lelei tulaga uma faiga uelo Faatinoga, ma sili ona maualalo le vevela aafiaga faigata, o le aafiaga o lona aofaiga ferrite i luga o le tau aafiaga (Laulau 3).
