Good luck generating a 1000 TeV neutrino beam with that flux. Currently, humanity is at 6.5 TeV for protons, which are easily acceleratable because they're charged. Neutrinos have to be produced through a fixed target collision setup which translates only a small fraction of the original energy into neutrinos. So I dare to predict that by the time we can have such a beam we have wiped ourselves out with nuclear bombs.
