Dear Ivor,

That photons in free space travel carrying energy at the speed of light
can I suppose be adopted as a basic fact but to make it the starting
principle of a completely new version of electrodynamics will be far
from simple and may be impossible.  Eventually you will have to explain
Oersted and Faraday's experimental results but on the way you have to
unravel the electromagnetic structure of the photon (or light) wavefield
which is after all what Maxwell first discovered together with the
connection between c and the units for measuring E and H.

Some aspects of Maxwell's thinking - particularly the notion of an all
pervading elastic aether, may now be discredited but that does not in my
view distract from his achievement.  Similarly the caloric theory of
heat, which you frequently deride,
[I have never derided it -
was the helpful basis on which Carnot
worked to develop his revolutionary theory of heat engines. The
indestructible caloric fluid powering the reversible heat engine just
turned out to be entropy not heat!

On the way from the travelling photon wave to Oersted you will have to
re-examine the coaxial cable where, as I and more impressive others such
as Jackson believe, careful experiments will reveal signal attenuation
and raise the question about what is happening to your light energy.
With judicious help from a battery this energy can no doubt be
maintained. Otherwise however, in purporting to sustain a permanent
state of stored energy in a capacitor through travelling photon waves,
you are effectively proposing what I think is called a perpetuum mobile
of the first kind.

Howie does not grasp cattq. http://www.ivorcatt.co.uk/cattq.htm . He has helped to silence it for 40 years. He was head of the Cavendish, Cambridge.
