Aren't you comparing kinetic versus potential without thought
to energy conservation

How about "power", Owen. Some physicists say that a
Poynting vector contains no power until some work
is done - that if an EM wave in free space never
encounters anything to which to transfer its energy,
its ExH watts are not power.

My question is: If an EM wave's ExH watts are not
power, what are those watts called? i.e. the units
of power are watts, but if in some cases, watts are
not power, what are they?
