Bruce is correct. The majority of the power output from the secondary is longitudinal in nature and will not show up directly on a scope, but it will be absorbed by water, if the water is entrained - and the frequency is right. You can see any transverse energy that may be induced by the longitudinal energy. This longitudinal energy must be converted to see it on a scope. This is what I was referring to before as energy conversion. Still working on ways of doing this that does not require water. It can light up a light bulb though. Try a much smaller value cap for higher impedance output, as it is entirely possible to swamp the output without even knowing it.

Yes, the order of the pulses is important, looked like you initially had it connect 1,3,2 instead of 1,2,3

The spool up and spool down is very common. It sounds like you may have had it and then lost it. Even though the energy is not directly viewable on the scope, you can see the impact it has upon the other parts of the system. Please be very careful, as even if you cannot view or measure the energy, it can get away from you.

For something you should be able view and test with transverse equipment, take a look at each of the longitudinal coil outputs while the unit is running. Resonance is not absolutely required to see an output, but frequency does affect how well it works. Compare the output characteristics to what has been described.

@Erdarion,

You might think about obtaining some neon NE-2 tubes, which might be available at your local or mail-order store.
They are available here:  http://www.neonixie.com/store/product_info.php?products_id=139

There are also small 4 to 8 Watt battery-powered flourescent tubes available.  Another possibility is to elevate the TPU on a plastic or mount so that the weight is carried by the mount, but lets a circular flourescent lamp fit around it such that the TPU is almost sitting on the round flourescent tube.  No weight or stress directly on the tube, of course.

This might be a good way to have a visual indication that something is happening or about to happen, even if you can not see it on your measuring equipment.

I have used such lamps in the past to test antenna tuners and antennas for Ham radio transmitters.

Thank you for all of your help and ideas!  I will see what I can do later on today (have to head off to work now).

So the coils on the top and bottom face of the core (at 90? to the primary coils) output conventional TEM energy?  That would explain why the odd things I was seeing were confined to the magnetic bias coils...and why SM tapped power from pickup coils in a similar configuration...

I'll let everyone know as soon as I have something.

Well, I have tried some other configurations, as well as the things suggested (except for the flouresecent tubes, don't have any that small yet).  No joy.

How am I supposed to tell if the system is running properly if I can't measure any output and a normal carbon resistor (or my light bulbs!) won't capture any energy???  I must be missing something here again!

I think you had mentioned that there is enough TEM gain to at least keep the system running.  Under which conditions will the TEM gain show up?

Do you have any ideas on how Steven Marks might be converting the LMD output of his coil into TEM?

Thanks!

Hey Eldarion,

Great results you are getting there! If you happen to be free tonight, get on Skype and I'll see if I can get you in touch with Bob directly to answer questions. Let me know .

God Bless,
