Haven't peeked inside yet :-(

Gray used the glass from a Coleman Lantern originally for the tube casing. In my opinion, that weighs heavily against there being either a vacuum or pressure in the tube.

That is not to say that at a later time there couldn't have been either one.

Respectfully, How does the super thin glass of a light bulb support a vacuum? Someone elts also made the exact statement about the glass of the lantern. I can assure you that if the lantern globe is properly supported and sealed at the ends. The thicker glass of the lantern Globe, can and will support a vaccum. If you apply enough vacuum to a vacuum tube or a light bulb they will also implode.

In my opinion you guys misunderstood word "vacuum". You don't need to take it literally "no air". In our case "Vacuum" means "no electrons".

I shall repeat my previous post for better explanation the words are in capitals. THIS IS DIRECT FROM TESLA PATENT.

Tesla's radiant energy patent 685 967

The device d (spark gap) is shown as composed of two very thin conducting plates. To improve their action they should be enclosed in a RECEPTACLE from which the AIR IS EXHAUSTED.

So it is starting to look like both Grays conversion tube and Tesla's radiant energy patent are both spark gaps in a tube from which their is NO or very little AIR!!!!!!

Ok has anyone tried building grays conversion tube with no air or very little air?

put your hands up....be honest?....who has built one?

One step closer

Here's the inside of my little $15 pump :-)

Deep thoughts

cool let us know how you go with this

Thanks for the water pump patent. This looks like probably the first turbine.

Seriously, though, I know which patent you mean. This device you're talking about was similar to an electroscope, with two thin metal strips hanging down. When charge accumulated, the strips attracted each other, eventually acting as a switch. The reason for the vacuum was to prevent charge from leaking off.

Here's an illustration of Tesla's longitudinal energy, without a vacuum:

So i take it you have built Tesla's radiant energy patent then?

Why does nobody try to add spherically layered beads in their spark gaps?

Then pick it up as radiant charge? Must be an interesting experiment since radiant likes dielectric materials, spherical geometry and layers(spherical capacitor). Use a metal ball core and paint it with diel. and cond. layers.

Dimensions are probably *very* important

Yesterday on the way home, I studied Grays patent more closely, and also the stuff on Zero Point Energy - Edwin Gray - Spark tube - MDG 2007.

It struck me that John Bedini wrote there:
"these tubes are about 3" in diameter grid spacing is 1/4 " between grids 5" long 1/4 inch brass rods with silver gaps. "

So: the spacing between the grids is the same as the rod diameter....

In the patent 4,595,975, there is a cross-section of the tube (fig 4) which also shows that both the spacing of the rod and the grids *and* the thickness of the grid tubes are very regular.

Since the spacing is 1/4", or about 3 mm, this suggests standing waves bouncing back and forth from the rod to the grids.

So, I made a sketch (attached) and did some calculations.

If the spacing between grids and rods is indeed about 3 mm *and* the thinkess of the grids is also 3 mm, we get a wavelength (lambda) of 6 mm.
This means standing waves at a frequency of 80 GHz. No sweat!
Obviously, waves at that kind of frequencies will definately reflect on metal surfaces.

This would mean that this baby basically is an electrostatic-laser!!

Hmm. It appears there's also a "maser" utilizing "Stimulated emission":

Maser - Wikipedia, the free encyclopedia
"The maser is based on the principle of stimulated emission proposed by Albert Einstein in 1917. When atoms have been put into an excited energy state, they can amplify radiation at the proper frequency. By putting such an amplifying medium in a resonant cavity, feedback is created that can produce coherent radiation."

Stimulated emission - Wikipedia, the free encyclopedia



BTW: maybe some more thinking is needed -- it might very well be that my 1 1/2 lambda is wrong, and should be 3 lambda, lowering the frequency to 'just"40 GHz...

Oops. That's ballocks of course, if it's 3 lambda, we would get 160 GHz...

Construction of a replication Gray Tube.

As I stated in my previous post, I think the dimensions of the Tube are very important. They should be such that a standing shock wave can occur.

Given the measurements as stated in my previous post, a replica could be constructed using more or less standard available copper rods (In The Netherlands available from Aluminium, metaal, messing, RVS, Aluminium platen ) with the following measurements (see attached sketch):

Rod: 1 tube, diameter 6 mm.

Inner Grid: 2 tubes.
Inner tube, inner diamater 12 mm: tube 15 x 1,5
Outer tube, outer diameter 18 mm: tube 18 x 1,5
Then, the inner tube will have an outer diameter of 15, and the outer tube will have an inner diameter of 15 also, so the can be soldered together into one tube of 18 x 3.

Outer "Grid": 1 tube, inner diameter 24 mm: 28 x 2.

For this tube, the outer diameter doesn't matter, since the waves should stay *inside* the tube. For that reason, I don't think any holes should be made in the outer "grid" tube.

BTW: I noticed a small error in my sketch -- I reversed the "9" and "12" in the cross-section picture, but you get the idea...

---

So, construction of the tubes should not be too difficult. Solder the two tubes for the interial grid together, and make some holes for the wave to be able to travel from the inner room to the outer room. How many, is anybody's guess, but that is probably not too critical.

As for the size of the holes, I would guess something in the order of a wave-length, so 6 mm will probably be a good guess to start with.

60 GHz

J. Chandra Bose was getting frequencies as high as 60 GHz back in the late 1800's. He used spoon shaped Resmods with short arc gaps.

J.C. Bose: 60 GHz in the 1890s

[lamare]

@Electrotek: An interesting read for sure.

One thing this shows beyond a shadow of doubt is that spark gaps are able to emit waves with that kind of high frequencies, because Bose also used spark gaps in his transmitter.

Tube Pressure

Patent #4845378 (EMP) states:

The flash-over becomes faster and the rise time shorter the higher the voltage, the higher the absolute pressure and the shorter the pole spacing.
