Always true.

It would be fun to play with such anomalies.

Take a look at a new mail I have sent on the list please. [Freenrg-L Discussion Group]

They should be posted by midnight tonight, if not by the time you read
this.

It makes things much, much easier for me. You can not imagine how helpfully it is :-)

I'll add 'thumb nails' and other web formating over the weekend, right now
lets just let every one see them.

It is good like it is now really. The main thing is there.

Please write up some thing saying how you took the pictures and such, I
know people will be asking me.

Some additional informations for you Bob:

Ball lightnings are only few millimeters (around 1/5“), which is very small. But considering the scale of the coil, they are very big and lasting very long. You see, when you notice the natural streamer, it is obvious, that the ball lightnings are very small in a ratio to the length of the streamer (they are only 11.8” - 20“ approx.). For us, they are huge. But the exact energy of such a streamer is very small - it is only an impulse. In these coils, the energy is very strong and repeatable.

My bigger coil (6kW) - streamers up to 7' long), will show ball lightnings which will last to 5sec., which will be record time, and they will last long enough to be examined in a controlled conditions in a lab, after the external power is shut down. this is very important. They will be like a golf ball in diameter, if not bigger than this.

Streamers that I have sent you are almost in a scale to the real model. So, you can see for yourself. Little smaller than that.

They can last (small as this), to 1sec. This is also very good, considering the energy. I think personally, that this is the record time of existence on such a small coil. It doesn't have enough energy to fire up more air or carbon for bigger nucleus. But as bigger they are, the time of their life is getting longer. So, people are usually see ball lightnings during the natural discharges, for few seconds. After that, they shrink, hit some other object… but evidently last to 10sec. in a best case.

Like I have said: they are lasting for a small period that I can not tell you anything more about the nature of their behavior. Something you can find in the mail I have sent on the list now. But some of them as you may see on the photos can last more, and move further from the coil, in the same manner, to be captured by the camera as further out. Sometimes, I shut down HV and they are still lasting for some time (this is very rear thing, I always must repeat experiment to achieve this - and this is due to the low power), and other close of the switch again is making new streamers. Some of them are again hitting the ball and it uses that energy to survive for a moment more, and than disappear.

I have said also that they are some sort of stars :-) They have initial fuel which they are spending through time, showing light and radiation energy in the space around. After all the fueled from the nucleus has been spent, they disappear in a form of supernovae. This is only analogy… but it will be interesting to see whether there is any relation at all between the stars and ball lightnings, or not. Especially where do they go after they vanish? Is there any form of matter still floating around? This is hard to show at this time, especially because I do not have any measuring equipment - my methods are different. Hardly that the regular ones could be used for this purpose, as they can not for non-hertzian waves. They are moving through the glass (windows), very easily, without breaking them or leaving any form of distortion at all. This is also very strange. They can move through matter!! But in the case of glass, it is understandable, knowing the specific relation between the electrical current and glass. Still, not quite.

This is the shortest I can offer for now. Later I will send you some more information, and after some further experiments if you like to be kept informed. [No further information was supplied.] But if you like you can ask questions, it is much easier for me to answer then, knowing what you are interested in. [Nele's last known email address is available on request, it is not posted to prevent Spam.]

Oh, yes, I forgot to tell you about the coil: Secondary coil which you can see is only 11,8” tall. That gives you the metrics of the machine. If you like other specific characteristics of the coil (frequency, wire,…., no problem).

I am taking pictures with a very old camera, using 100ASA 24DIN film. Exposure time is from 1/125 to few seconds. It doesn't matter really, when you are making these photographs in a dark room which is the best by the way. You also need mechanical camera, not by any chance digital one, or it will burn, because of the HV in the air. The scale is almost right on the photos you can see on your screen.

It all depends on what you want to see. You can see that on some photos, there are great amount of streamers and sparks, issuing from the terminal. This is due to the higher exposure time. On other ones in a contrary, you can see only few of them, this was important to capture ball lightnings. But, maybe it would be the best to say that all that looks much better in a real time :-)

> appreciated, and would save me some time, because of work …

Happy to help the Freenrg cause any way that I can, will let you do more
cool experiments. :-)

Yes, I am very rarely on the list, maybe there was no subject for me all that time. Now, someone has mentioned plasma balls. I have great amount of experiments behind me about Tesla coils, mechanical oscillators (earthquake machines), wireless power distribution…

Thanks Bob!
