Hi Arthur,

Very interesting assumption. I suppose (and that is always a risk
with a renowned theoretician such as yourself) that you have an
instrument that can detect the difference in radiation between a solid
wire and a tubular one - all other externalities being the same?

No, I suppose not. You've been burnt too many times with your own
results confounding your expectations. However, putting that grief
aside (and it must be a terrible burden to endure), if a hollow
element were filled with a custard center so that it was in
equilibrium, would it radiate?
