High Energy Neutrino may lead to a New High Energy Astronomy. Neutrino interaction in matter at PeVs- EeVs may behave differently from Standard Model predictions because possible TeV Gravity scenario. While traditional km3 neutrino underground detector will be uneasy to disentangle the Gravity TeV scenario any new Horizontal Tau Air-Shower detectors at PeVs tau energy, beyond Mountain Chains, will be greatly enhanced and it may probe fruit-fully the New TeV Physics imprint. Moreover observing upcoming and horizontal tau air-showers UPTAUS, HORTAUS from high mountains toward Mount Chains or along widest Earth Crust crown masses at the Horizons edges, Ultra High Energy,UHE, nutau and its consequent tau lepton decay in flight, will greatly amplify any single UHE nutau track and it will test, at highest energies, huge volumes comparable to underground km3 ones; observing UPTAUS and HORTAUs from higher balloons or satellites at orbit altitudes, at GZK energies, the Horizontal Crown effective Masses may even exceed 150 km3. These Highest energies (1019 eV) nu astronomy are tuned to test the needed abundant nu fluence in GZK Z-Showering model: in this scenario ZeV Ultra High Energy neutrino are hitting on relic light (0.1-5 eV masses) anti-neutrinos, clustered in dark hot halos, creating UHE Z bosons whose decay in flight may be the hadronic secondaries observed on Earth atmosphere as UHECR, isotropically spread along the cosmic edges and clustered toward few correlated BL Lac sources.
