Abstract: The detection of high energy astrophysical neutrinos is an important step toward understanding the most energetic cosmic accelerators. IceCube has observed the first astrophysical neutrinos and identified the first potential sources. However, the best sensitivity at the highest energies comes from detectors that look for coherent radio Cherenkov emission from neutrino interactions. I will give an overview of the state of current experimental efforts, and then discuss two new experiments, RNO-G and PUEO, that are currently being constructed to discover neutrinos at the highest energies and push the energy threshold for radio detection down to overlap with the energy range probed by IceCube, covering the full astrophysical energy range out to the highest energies, and opening up new phase space for discovery.
