How?  I'd really like to hear about these experiments.  Did they fail
as candidates because you couldn't demonstrate telepathy, by any chance?

And radio emissions are practical in your opinion?

The membrane is around 10 nm (10 x 10^-9 meters).  Radio waves, which
are only a part of a larger electromagnetic spectrum
(i.e. distinguished from light or heat by their wavelength only, not
by any other characteristic), are measured in centimeters and meters,
I believe.  Their wavelengths are several orders of magnitude greater
than the thickness of the membrane.  Also, neural signal processing is
restricted to frequencies well below 100 kHz.  Radio waves are
measured in MHz. 

I think that the fact that people are oblivious to very strong radio
emissions from conventional broadcasting devices (TV, radio, radar,
cell phone, etc) make it highly unlikeyly that they are going to be
receptive to signals too weak to detect by conventional receiving

A rattle snake is no more closely related to a marine animal than you
or I.  And anyway, the brains of all vertebrates are encased in a jug
of saline water (cerebro-spinal fluid) in addition to the saline
solution in the interstitial spaces.  I expect our brains are more

And even in a vacuum its going to fall off as the square of the
distance.  If you have to use ultra-sensitive equipment at very close
range just to detect the emission of very weak radio waves from brains
then you will have a very difficult time convincing any rational
person that it is a viable medium of communication.  I think you are
playing a loosing hand.  Give it up.
