I roto i te 1984, Herb Chen o te Whare Wānanga o California i Irvine tuatahi tohu i te painga o te whakamahi i te wai taimaha rite te pūoko mō te neutrinos solar. Rerekē i pūoko o mua, te whakamahi i te wai taimaha e hanga i te pūoko tairongo ki rua tauhohenga, kotahi tauhohenga tairongo ki nga kakara katoa neutrino, te tahi atu tauhohenga tairongo ki te neutrino hiko anake. Na, ka taea e taua pūoko te ine i neutrino ngaru tika. He wāhi i roto i Canada i ahuareka no te mea Atomic Energy o Canada Limited, e pupuri ana i te taonga nui o te wai taimaha ki te tautoko i ona CANDU reactor tipu mana, i pai ki te nama i te nui e tika ana (CUM $ 330,000 i utu mākete) i te kore utu.
