I think in theory that patent is then null and void!! However theory and
practice are in theory the same, but in practice they rarely are :-))

>From an engineering point of view, a scientific theory does not have to be
true.  It just has to be useful.  That is, it enables us to build something
to meet our needs and for an acceptable cost.

For the FSL antenna to be taken seriously, we need one or more examples of
successful implementations, preferably combined with a set of formulae from
which we can construct devices to meet our requirements.

The same applies (by the way) to the Cross Field Antenna. I have read the
patent specification and I cannot see from that how to build something for
137 kHz, even though the inventor assured me it could be done.
