Author Topic: Tesla's Utilization of Radiant Energy and Heaviside's Electric Field disturbed  (Read 6163 times)

I am posting this for everyone to criticize and (hopefully) explore.
It seems that there is a simple connection ( in my opinion ) between Tesla's Apparatus for Utilization of Radiant Energy (patent 685,957) and Heaviside's theory for Electric Field distributed by a Foreign Body (#77) - Electromagnetic Theory, Volume I, 1893
As probably most of you are familiar with Tesla's patent, I will not discuss it, but will note one thing that, besides everything else, that seems to be important: an insulated metal plate - any dielectrically coated NON-conductor (metal) with different shape, type of dielectric and type of metal, can be used here, and this will lead to a variety in the system  coefficients leading to different efficiency.
Now, I am using a "NON-conductor" to for a metal-type substance, "conductor" as widely known, having properties to provide energy guide, and NOT pass-through, to the electrical energy. After this sentence probably you are already confused, and that is good, because you have to be!
In order to get you thoughts in some order probably the best thing is to read and analyse, chapter I and II of Heaviside's Electromagnetic Theory, Volume I. Just two small quotes form it:
"Passing to the case of a very long straight round wire supporting an electric current, we are bound to conclude that the transference of energy takes place transversely, not longitudinally; that is, across the wire instead of a long it. The source of energy must, therefore, first supply the dielectric surrounding the wire before the substance of wire itself can be influenced; that is, the dielectric must be the real primary agent in the electromagnetic phenomena connected with the electric current in the wire." - p.17
"they will afterwards look upon the notion of its ( energy ) going through the conductor as perfectly absurd, and will wonder how anyone ever could have believed it" -  p. 73

So, basically, reading though the chapters, gives you a very different idea ( from the one  you have been indoctrinated with ) that, the energy flows close to the metal, through the DIELECTRIC. And the metal shapes are something like energy guides, and energy slides over them as some of it, but only (small) resistance like amount, curves to it ( as far as I know T. Bearden talks about it as well as E. Dollard ).

So having (hopefully) straighten the concept where the energy flows, I will not use any more the word "insulator" and "conductor" ( for metals ) for it is confusing but dielectric and energy-guide ( metal: actually a dielectric where the permittivity is almost, but not, zero ).

Now going forward in Heavisde's Electromagnetic Theory, p. 94 ( at the bottom ), we see a quite interesting conclusions:
"When the transverse voltage, of the condenser is maintained constant by connection with a suitable source (my note: constant E gradient, and also "condenser" here has wider meaning ), the insertion of the foreign body, which increases or reduces the remittance of the condenser, will increase or reduce its charge under the action of the constant source, besides concentrating the displacement within the body, or the reverse. With constant charges, however, when the plates are insulated, the insertion of the foreign body will reduce the transverse voltage when its permittivity exceeds that of the air; and conversely. Increase of permittivity also increases the stored energy when the transverse voltage is constant, but reduces it when the charges are constant."

Now with the above in mind, it seems that Tesla's patent actually is an implementation of this idea/view, as one of the "condenser" plates is the elevated metal plate ( energy-guide ) and the "foreign body" - the dielectric with higher permittivity, than the air - energy concentrator - is the dielectric coating over the plate. It increases the permittivity of the "condenser" and in this way increases the charges sliding over the surface of the metal plate. In this system we have a permanent E gradient ( constant V ), existing in the dielectric with lower permeability (air),  and is permanent E is being concentrated by the dielectric with the higher permeability. Note that if this dielectric has electret properties the effect should be highly enhanced.

Heaviside also notes that the concentrated E force/field, that creates pressure on the metal plate, ( and from that curl, and this is how we can the power appearing on over the energy-guide): "Since its own stress balances itself, we see that whatever the forcive on the piece may be it must be statically equivalent to the action upon its boundary of the external stress only, constituting an external surface traction.

I would like to add that there is some experimental research/development pointing in this direction. Bruce A. Perreault has page that can be associated with this idea (in my view of course):

And if some of you dare to dwindle through the pages of Heaviside's Electromagnetic theory, a  controversial question, naturally, starts to appear in ones mind: What is a true conductor and a true insulator? It seems that a true conductor is EVERY LIVING thing, using the power from the constant E field - energy, and a true insulator is the one we consider NON-LIVING, not being able to conduct the energy but only to guide it and express its resistance to it in a form of heat.
Now as may of you are probably more confused than ever. I will leave it here,  and hope that this confusion ( with time and rethinking ) can only produce, more development research in this direction. Or criticize me to eternity, for daring to suggest such outrageous direction of thinking.

Best to all,

PS: the title of the topic should have been better expressed, but somehow I have typing restriction for subject length.

That is true, but you can also find it in modern electromagnetic theory books.
Energy flows in dielectric around conductor, conductors are energy guides.
Surprisingly, I always find people that look at me with a big eyes when I say this, even proffesionals EE or IT engineers.
For radio engineers, dealing with antennas ,waveguides and RF it is obvious.
It is nice you started this thread.
I didn't read all Heaviside books, but I find his work somewhat forgotten.
