Not really, I believe the core component in his device is just what he states, simple.  The concept behind it is key and has been discussed here in another thread.  It's using straight old EM theory no aether or NMR and uses two standard electric/electronic components.   

I know you've seen the videos of people dropping magnets down copper tubes, it falls slowly if the tube is continuous but put a slit in it and it falls due gravity, why? Doesn't induction occur in the tube with the slit and if so where does that energy go?  What electronic component is the tube with the slit comparable to, think simple.

Why is this whole room shielded with copper plates (grids)?

Was the shielding constructed by the demo-givers or demo-takers ?

I have been saying this the whole time. Shielding and using the ground to create a sink for charges collected from the environment.

 Well well... Nice to see people coming around to what is really going on. I have been saying this the whole time. Shielding and using the ground to create a sink for charges collected from the environment.


 What's in the can is simply a special transformer in oil, like I have shown many times. The capacitor is seen outside of the can with the 2005 device (back yard device) that he had in the house. The cap is the filter he is talking about.


 Someone asked how they loop the device well quite simply since it is a high frequency device then all one needs is to put it through a bridge rectifier and another special split core transformer. In the backyard device video you can see both transformer and diode bridge in a special pack he designed that happens to be shielded as well. The diode bridge strips the high frequency and then it can be looped to the inverter.


 The problem is so many tend to complicate things so bad that they don't see the "magic". Others have agendas and try to dissuade others from trying the right way. They throw all kinds of math and other "laws" at you to confuse us and puff their ego's up in the same process.


 Anyways you guys are on the right track now just keep looking and you will see the real way.

Did you not see the link to the lecture Tesla did that I posted. Not only is there a good picture of the coils but the text gives everything you need to recreate the special coil. This includes bobbin size and even wire gauges.


 Here is the link if you need it again:

Start at figure 3. The text talks about everything you need to know. Even about the shielding this coil will need and the effects of having that shielding to close to the coils.

 Oh and there is a complete picture of the circuit which will include the spark gap and it's various incarnations that Tesla used. Tesla said the magnetic quenched spark gap was optimal for tuning and disruptive discharging of the capacitor(Leyden jar). I recommend the oil filled capacitor since it will be able to handle the excessive voltage that will be forming inside of the capacitor. Read the text below the figure 3 for more information and recommendations of Tesla on this experimental device.

 Alway respect voltages in excess of 1kilo volt.
