    Do you think that the interior of the coils need to be manipulated so the kick doesn't end up getting absorbed there.

No.  Keep the core "air"  - low loss plastic if you want - PVC is marginal - Teflon is great - rolled poly sheet is quick and easy.

Tip from Eric Dollard:

"matter" will distort the field.  This includes insulators.  He felt that the rod-type supports were best - better than solid plastic which is worst.

Just get a kick at this point though

replace the metal components with nylon or delrin equivalents.

McMaster.com has them - fast shpping.

Alternate is to hot-glue with plastic - get 'er dun!

Thanks for that Grumpy i thought of using nylon, as of now , they are nonferrous (brass)..has anyone had progress with a circuit ., i'm leaning towards Earls rat race controller, since i have been offline for awhile , have there been any developments in circuitry? oh and a big thanks to overunity for making the net what it was meant for, liberation through bringing ideas together

arggg... my tounge is getting hurt from biting it so hard. Enough!

Spherics description has some remarkable consistencies... but lets get the things I dont agree with out of the way to start with... There is one slip up (the 30 deg angle) that I think is an honest mistake and one thing I disagree with (the iorn related NMR and special topology).

I cant believe that no one here has noticed the *exact* match between the kick coil description and the coil and drive described in the Italian Energia patent. Unless one is copying the other this provides mutual support for this mechanism.

The description of the inital discovery and development is highly plausable and consistent. SM was into audio development -- to gain lower impedance in voice coils bifilar winding is a good way to go. It is also plausable to apply slightly delayed signals to the windings (short enough delay not to affect the audio response) in an attempt to further reduce the impedance. Acording to Spherics this led SM to notice the kick effect -- exactly as the Energia patent also documents.

As for the final evolved configuration that Spherics starts with. This reduces to a non-radiating antenna configuration with fleid rotation. I doub't Spherics or co-workers new this. Non-raditaing configurations are a very recent discovery and very little known. A consequence of non-radiation at resonance is that the antenna will actually trap energy at that frequency. These configurations will deliver energy into heating any nearby material that unbalances the configuration. When balanced they are truly non radiating at the resonant frequency. In the far field the fourier energy at the resonant frequency falls to zero.

@keytone
Any unbalancing of a non-radiating antenna configuration will destroy it's effect -- this includes magnetic materials *and* dielectrics anywhere close to it.  What support materials you do use should be radially symetric about the vertical axis.

@all
here is a controller circuit I have designed and tested -- it works perfectly in practice -- This will all be documented and released shortly along with an advanced half bridge mosfet switch design that will let people switch reactive loads hard (under 10ns) from 0 - 500V or more at up to 5MHz. Again this has been designed and tested already - it's just waiting for prototype boards and broader testing before fully documenting and general release.

This control circuit will generate relative pulse durations or user selectable fixed pulse widths. It's good to about 40MHz using 74F seris logic (you need 74AHCT for the 123 as it's not availble in the 74F part).

Note: with the drive waveform Spherics suggests all four coils will resonate at the *same* frequency -- at resonance. This results in a virtual dipole with a rotating field. Around this - exactly half way up, is a toroidal coil. This dipole and toroid are the non-radiating antenna configuration.
