The "non-Fourier" propagation mode I am describing as implicated in Piantelli's Ni rod LENR only occurs in metals. It is about 50x faster than normal thermal propagation, but still <10x (slower than) the speed of sound. A useful reference to this thermal wave in metals is:
N. I. Kobasko, SH. E. Guseynov, An Explanation of the Nature of Thermal Waves “a Poker Effect” on the Basis of Hyperbolic Heat Conductivity Equation Analysis and Existence of Free Electrons in Metals,* Recent Researches in Circuits and Systems* (2014), ISBN 978-1-61804-108-1, WSEAS Press, 167-172 I don't believe it is related to the ORNL paper, but that paper has some interesting concepts. Having a dielectric with super high heat transfer is a holy grail technology. For thermoelectrics, what is needed to go along with that is a semiconductor with almost no thermal conductivity (very high thermal resistance) and near 0 electrical resistance.
