Neutrinos produced in the early moments of the Big Bang are believed to be the second most abundant particle in the Universe.  A method of experimental detection, called PTOLEMY, has been developed to map the flux of neutrinos on the sky and provide independent confirmation of the power spectrum from the inflationary pre-Big Bang period.  The challenges of ultracold relic neutrino detection have led to new advances in material technologies, RF detection and an electromagnetic spectrometer which doubles as a new type of particle accelerator with potential use for plasma heating.  The current status and outlook of PTOLEMY are presented.
