At 295 K we measure an in-plane resistivity of 2.6 \\mu{\\Omega}-cm, making PdCoO2 the most conductive oxide known. The low-temperature in-plane resistivity has an activated rather than the usual T^5 temperature dependence, suggesting a gapping of effective scattering that is consistent with phonon drag. Below 10 K, the transport mean free path is 20 \\mum, approximately 10^5 lattice spacings and an astoundingly high value for flux-grown crystals. We discuss the origin of these properties in light of ","authors_text":"Alexandra S. Gibbs, Andrew P. Mackenzie, Clifford W. Hicks, Edward A.
