What virtually every engineer means when he says, "power flow",
is, "the power (energy per unit-time) associated with the energy
flow". Knowing Jim, he would also probably argue that the sun
doesn't rise - that instead, the earth rotates. However, most
weather forcasts on TV gives the times for sunrise and sunset.

Yea, somebody around here once said that I would probably step out of
the shower to take a pee. To that I say why would anyone step into it
to take one? ;-)
