This presents the interesting idea that a wave disturbance can leak
out of a flaring volume, and resonantly transfer some of its energy
to neighboring regions.
The strong point of such an idea is that
it can explain how energetic electrons, known from their hard X-ray
signatures to be in the
deepest atmosphere and on
closed field
structures, can also find themselves on flux tubes immediately
connecting into the heliosphere.
One drawback that the Archivist can imagine (other than the usual
matter of unravelling all of the strong assumptions in such a theory):
How can this resonant wave transport picture be very efficient,
given the geometry?
In other words, how do the waves seek out and find the open fields?
The answer to this might be that we don't need many electrons to
generate a type III burst.
