magnetic coupling to the stream seems kind of odd, but it appears to
work for him. i wonder what happens if you go qro? i would expect
some heating of the water and maybe even some ionization or corona
that might cause instability in the stream. i would also guess the
tuning would be difficult in high winds.

Wind would seem to be a weak point. The top of the conductive stream
would dissipate at different heights depending on the wind velocity, so
a gusty wind would be constantly altering the effective antenna length.
