 +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
 +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 :-)

 +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!
