We "point out" some possibly serious errors which can arise from Poynting's treatment of energy fluxes - especially for time independent current flows in electrical conductors. The basic error made by Poynting is that he assumed, essentially that if two vectors, A and B have the same divergence then A = B. We show how this reasoning can be extended to hydrodynamics, and bow it can be used to explain some other quite unexpected results in soccer! We will also outline some of the difficulties we have experienced in trying to publish our results.
