Keep discovering, Hello tekbox! welcome to the Tesla research forum. The forum is still under construction but I hope that it will be ready as soon as possible and then I'll call other users which probablly would be interested. By now Im very busy organizing again the whole website. Now most of the contents are organized but most of them are hidden and it will be displayed as soon as we verify all the information to display it in the public webpage. We still have so much pending work and for this reason the forum is still unfinished. I will send to you the password of the extended research as soon as everything is ready to continue, but we had to do a great modification of the webpage one month ago and we are still working on it to prevent any problem with copyrights. The webpage will be improved in different aspects in the near future after we contacted the original sources but by now many contents are hidden in the public wepage. I also talked with some people and I found some engineers to colaborate because they would have the right clues to analize every precise subject and to work together. It is awsome that you are experimenting with this because I allways had a lot of questions, and I been searching for it for so long time. You are welcome to share your results and some new explanations would be created for the research. You would be able to decide what to show in public and what to hide to develop the project properlly. Our intention is to provide some way to meet people which would offer colaboration and experience to develop this kind of experiments. I contacted some experimenters in my attempt to get some information on the longitidinal waves in plasma or resonance in vacuum tubes and I will ask to them again to get some technical details and formulas to add in this post and to see if it would be helpfull to design some experiments. In fact I probablly had the same idea as you but Im still busy adding some basic contents and for this reason I still didn't have so much time to dedicate to the research. In the case of the death ray I think that it also may have some relation with the x ray emission at long distances by Tesla which appeared in some articles but I think that some of them are missing in the list of articles on the death ray from Teslaresearch. Anyway, I will try to get some precise information and I will contact with some people to add whatever I get as soon as possible. |

![]() Hello, I am working on a small open cavity vac tube to help verify Mr. Tesla's claim of open air particle acceleration. It seems to work on the same principal as Bernoulli vacuum . The pipet particle emitter in my experiment will be a valvular conduit made of 1/4" OD copper tube. (Just a test). I hope to see some real activity on this site soon . Keep discovering, In the death ray proposal - The new art of projecting concentrated non-dispersive energy through natural media - Tesla explains about some details of a modifyed OVT and I found this picture:  If Im not wrong, the effect of the Open Vacuum Tube consist of creating a great depression in the conduit 1 (High vacuum chamber) by using the force of the direction of the stream of compressed & dissecated air to create the the depression (which looks like the ventury effect, but Im not sure if its the same). According to Tesla: " Some allowance should be made for the frictional loss in the nozzle and the outlet channel and also for the deflection of the jet. For most purposes, the velocity need not be much greater, but as the degree of rarefaction depends on the square of V, it is desirable to obtain as high a value as practicable. Usually, vacuums obtained by a mercury vapor pump are considered very high. In those, the velocity is only 280 meters per second but the vapor is 6.9 times heavier than air.
Therefore to get the same vacuum in the air jet, its speed should be 280 x [6.9]1/2 = 735 meters. With a working medium at high temperature and pressure, both within practicable limits, this value can be attained and even exceeded. Thus, a gaseous jet of very high velocity affords a means for closing the end of the tube, more perfectly than any window that can be made while at the same time permitting and facilitating the exit of the particles. Referring to fig. 2., it shows schematically a modified form of my tube intended for various scientific and practical uses when it may be preferable or necessary not to discharge the jet through the open end. The construction of the device will be easily understood in view of the foregoing description like parts being similarly designated. A cylindrical conduit 1, is provided as in fig. 1, but the outer cone is replaced by a block 2, of lava or other insulating material shaped as indicated and firmly cemented to the conduit 1, which is hermetically joined by a nut 4, to a metallic plug 3, having a central hole, and extensions 3 and 6, serving the purpose stated above. The working fluid, as compressed desiccated air, is supplied by means of a pipe 7, to a large annular space around conduit 1, and escapes through an expanding nozzle 8, formed by the tapering part of the block and the end of the conduit, into a chamber connected by a pipe 10, to a vacuum pump of large capacity - not shown on the drawing - for carrying off not only the air issuing from the nozzle but also that rushing in from the outside through the open end 9. In order to minimize the volume of the latter, I avail myself of an invention of mine known as the "valvular conduit" by providing the wall of the open end 9, with recesses as indicated giving rise to whirls and eddies which use up some of the energy of the stream and reduce its velocity. In this way, a pressure of about 100 millimeters of mercury can be readily maintained in the chamber increasing greatly the expansion ration of the air and its speed through the nozzle.".When I saw the OVT for first time I already missed some exit to extract the air probablly mixed with mercury and using high vacuum to increase the force (but Im not sure if I understood his explanation). I thought that Tesla would never forget such a detail but the modifyed OVT appears designed in the right way. I believe that it wouldn't have enough force with the simple configuration and it would probably represent a waste of mercury. It would be interesting to develop experiments with a Lenard x ray tube and connect it to the OVT but I obviously didn't find enough information on this subject and I think it would be dangerous to work with mercury vapor. I though that the OVT would use the Ventury effect but I never read about the Bernoulli vacuum. I think that you wanted to say this: www.physics.umn.edu/outreach/pforce/circus/Bernoulli.htmlI found many references with this name and Im not sure which is the right one. |

Thankyou to provide this information about this effect and don't worry to take your time to answer. This webpage is created progressively because it is like a hobby but our intention is to develop everything as technical as possible to be able to share usefull information and not only to share opinions and the only problem is that we should first finish to add the most basic contents, but it takes time to write again every info of every category. Yesturday we tryed to activate the restricted area but it didn't ask for any password and we had to close it again anf for this reason it will probablly take a few weeks because I have some technical problems to develop the right way to share the extended research, but it will happend in some time. I already seen some of those experiments of some Bernouli demonstrations and I understand what you tryed to say. I will soon add some formula and schematics on fluid dynamics and pressure systems to get some precise idea to compare it with Tesla's invention, and it also would be usefull to create some section on this subject in the category called "modern technology concepts" to give some deep analisis of every technical features. I found this simple scheme of an "Adjustable Air Venturi Vacuum Generator Pump" which I think it is the same as you told and where it appears to be almost the same configuration of the OVT: |

I been investigating on the "Adjustable Air Venturi Vacuum Generator Pump" but also about fluid dynamics and the venturi effect, because I don't have many clues on this field and it is allways a nice occasion to learn. I created a section on "fuild dynamics" in the category called "modern technolgy concepts" where it will be added as many technical concepts on fluid dynamics as possible. By other hand I created another section in the category of the "death ray" to investigate some details to develop experiments of the OVT (where I'll copy any further informations from this post) but also any other parts of the death ray proposal. To begin with something I think that it would be usefull to create various designs for experimental models with the help of some exemples of vacuums pumps from the market with the technical features to apply the formulas to get some clues about the force of suction, and the pressure of air needed to create vacuum. Knowing that it could be compressible or incompressible fluid, I should create the same exemples in both 2 methods but also mixing them to see which result could be obtained. In the following link appears 2 exemples of adjustable Air Venturi Vacuum Generator Pump: www.2linc.com/venturi_vacuum.htmTechnical features of both vacuum pumps: -Maximum vacuum generated is 22"HG - 26"HG = 10.8psi-12.8psi = 0.744633bar-0.882529bar -Only 70-80PSI (= 4.826330bar-5.515805bar) air pressure is required to obtain the maximum vacuum. Now Im calculating it with the formulas on Bernoulli effect and I will add them very soon in this same message to complete the exemple. Im adding some links in the death ray category to investigate different aspects and to get the formulas & graphics. |
