this is interesting...http://www.physforum.com/index.php?act=idx.....also
i found this text..START...Sir William Crookes had seen within the action space of his now famed high vacuum tube — There, suspended over the cathode, was a black space which was actually radiant. THe radiance extended beyond the tube walls in certain special instances. Sir William had no difficulty accepting the fact that this was a "space–permeating" blackness, a radiance having far greater significance than a mere physical phenomenon. ... (p257)
George Piggot mentioned the mysterious "black bands" which appeard around his highly charged suspended metal marbles. Light seemed to disappear into these zones.
It was Nikola Tesla whose forgotten and ignored testimony on the perceptual effects of high voltage electrical systems, who made the most observations. Tesla produced such intense electrical arcs that the same "blackout effects" were repeatedly observed. In the case of Tesla's famed Colorado Springs Experiments, the blackout effect produced a lingering state which Tesla described as a perceptual-spatial distortion.
Noted in his published diary, the results followed the intense activity of his Magnifying Transformer. Visual distortions, clarifications, black shadows, black streamers, black waves, lingered for hours all around his plateau labroratory, whereby he stated that:
"These phenomenon are so striking that they cannot be satisfactorily explain by any plausible hypothesis, and I am led to believe that possibly the strong electrification of the air, which is often noted to an extraordinary degree, may be more or less responsible for their occurrence."
STOP...this is interesting, i had never read any of this but suspected that it must have been documented...i am glad it was the likes of Tesla and others who reported on these effects....i am trying to get the link...http://www.google.com/url?sa=t&source=w ... HcuQ...try
that link and i will be searching for more stuff...david
