First I answered quite a few questions about the 60 hz resonances I have procurred to the moderator of tesla pupman list, but when another poster asked a question it was refused as off topic. I also have now come to a point of application concerning interphasal resonances as I have promoted through my teslafy yahoo group. This will be a consideration of the resonant ferrite heating phenomenon and how it should be shown as a conversion of time into energy. A you tube video is planned, but now I must remove the table apparatus shown below for that newest demo of 3 phase 465 hz from car alternator to show time distortion effect.

No, I merely noted that MORE power could be transmitted through the air then when the same load is attached to the delivery wires, but this happens at a cost of delivery efficiency. In the following jpeg http://www.flickr.com/photos/harvich/3338764080/ On the left primary side 60 volts inputs inputs 332 ma for an apparent power input of 19.92 watts. The wire resistance on both primary and secondary being 140 ohms, the I^2R losses on the primary will be 15.43 watts. If the primary configured as a series resonance were to have its theoretical Q factor determined by X(L)/R realized, both the apparent power input and the resistive wattage would be identical, but this seldom ever occurs so we note the "acting" Q factor that the real components can deliver. One must realize of course that since the primary and secondaries are in mutual induction, and that the secondaries currents producing an opposing magnetic field 90 degrees out of phase with the primaries magnetic field; this of course influences the X(L) quantity of the primary which in the tuning of the primary, equal inductive and capacitive reactive currents are sought. Thus the primary tuned in isolation uses a different C value of identical reactance then in the situation when an identical secondary is brought into the primary magnetic fields vicinity. Technically the primaries X(L) value changes with the presence of the secondary coil as a short in which feeble currents ensue on the secondary by lenz law which in turn slightly decreases the primaries X(L) value. Now when the secondary is given its estimated C value across the former short as a loop of induced currents, the secondaries currents in the loop increase by its Q factor, which in turn further decreases the primaries acting X(L) value. Even further then this when the nite lite bulb is placed across the secondary LC induced current loop this then diverts a portion of current from that loop which in turn now increases the primaries X(L) value. We see here that after this is done whereby 26 ma is obtained across the secondaries LC currents reducing them to 84.5 ma, which is one quarter of the primary amperage input. Thus on the secondary end we have .98 watt I^2R wire losses and the wattage across the bulb would be determined by its acting resistance where 79 volts enabling .026 A would be 3038 ohms, and a mere 2.05 watts is expended on the bulb. So we have an apparent 15 watts in and only 3 watts out, not very efficient. It should also be realized that even though the coils have equal amounts of windings, that the voltage rise appearing as an input voltage across a load from the secondary will only take place when the ratio of load resistance vs secondary 140 ohms internal resistance is high as in this example. If a lower filament resistance bulb were chosen as the load, that load would no longer derive more power through the air then if directly connected to the primaries input voltage delivery lines. Thus this is a somewhat unique example when this can occur, but as noted with a great loss of efficiency. Perhaps if a matching 140 ohm secondary load were chosen the efficiency of delivery might improve... At 60 volts direct line input the bulb should conduct 3/4 the former currents and only consume 1.18 watts. But we can get 2.05 watts through the air at a ~ 15 primary watt input. By initially tuning the coils for magnetic opposition as two inversely phased series resonances, both of the X(L) changes on each side can be used to tune to, and then later that C value used as the estimated needed secondary capacity. In that case the magnetic fields are 180 out of phase, and we further assume that when one side of the circuit is disconnected as a secondary shorted LC loop, that its responding magnetic fields are then 90 degrees out of phase by lenz law. Hope this explains somewhat the turns ratio paradox, and how the voltage to an air core secondary load is determined by load resistance vs supply internal resistance. HDN Your request to the Tesla mailing list Posting of your message titled "RE: [TCML] 60 Hz Binary Resonant Primary Design" has been rejected by the list moderator. The moderator gave the following reason for rejecting your request: "Your message was deemed inappropriate by the moderator. Hi Harvey, It's time to bring your posts to the topic of Tesla coils. Resonance alone is not on-topic. I believe that you're fundamentally mistaken in looking for standing waves in wound coils. Wire length has no value in Tesla coil secondary analysis, and it's probably leading you to all kinds of incorrect conclusions regarding your coils. But regardless, I see nothing in your recent posts applicable to Tesla coils.
