As I recall, all of the open pickup coils do not absorb any energy. But any pickup coil that has a load will take energy away from the other coils.

Ok Thanks , Dose a closed secondary equals to a load .

A can put pretty much any resistor on it , the jt pulse barely changes .

i just designed the worlds first high power tesla  wirelss transmitter ...

you bet it uses a jt ...  2 panckkes .. and many feroite transformers or rods ..  as colpasers...  and there sent out the tower... 

did i build it no ... 

will it work yes!

i think he wrote some where 0 loss when mass tuned .... 

is this correct xee2?

@all

I just took a dc motor from a tape deck , and connected it to the battery it tuned slowly at 1.3 volt but , it also runs i bit faster on the rectified secondary. The motor is stronger on the battery.

I also found small light bulb , it also light on the secondary directly one the bridge , lights about the same as direct on the battery .

I don't know if those are regular things , before i forget i also put a electrolytic cap 1000mf on collector to negative rail , it charged leds on the secondary not affected.

Is this good ? should i make pictures ?

Edit it light from the pickup coil no bridge even brighter then direct on the battery , look the led it also working on the collector /- of the jt.

I do not know of any simple JT that will light a filament bulb directly from the pickup coil with only a bridge. But I am confused. A filament bulb should light with AC or DC so you should not need to rectify the pickup coil output to light the bulb.

Can you post a diagram of what your circuit is? If you are using a 1.5 volt AA for power it would seem that you are getting much higher efficiency than a regular JT.

I am not sure. Jeanna is the Tesla writings expert.
