Text: Letter to the editor. "Alternative choice for the energy flow vector of the electromagnetic field." Mentions eight alternative energy flow vectors proposed by Slepian that satisfy Poynting's theorem. It is now well established that some static electromagnetic fields possess angular momentum. It is required that the energy flow vector be the usual Poynting vector. Points out that the fact that a stationary object can possess angular momentum is rather shocking, at first sight, but it is clearly inevitable. References are given. Note that, if the angular momentum of a stationary object could be "tapped", one could possibly obtain "free energy". American Journal of Physics. 50(6), June, 1982. p. 492.
