The invention relates to the field of energy production and of synthesis of chemical elements and in particular to adaptations allowing creating conditions equivalent to those of a black hole for the purposes of production of energy and production of chemical elements such as rare metals.
A possible definition of a black hole is that of a dense object (body) surrounded by an area of swirling ionised hot gas called the accretion area, an area in which nuclear fusion and transmutation reactions of chemical elements occur.
There are many other definitions of the black hole.
For some, a black hole is a celestial object so compact that the intensity of its gravitational field prevents any form of matter or radiation from escaping from it.
Such objects can neither emit nor scatter light and are therefore black, which in astronomy means that they are optically invisible.
For others, like Hawking, a black hole could emit radiation.
While till now no one has been able to directly observe a black hole, nor know what is really happening inside this black hole, several indirect observation techniques in different wavelengths have been developed and allow studying many phenomena induced thereby. In particular, the matter trapped in a black hole, swirling around it and the site of numerous nuclear fusion and transmutation reactions is heated up to very high temperatures and emits a large amount of radiations.
Because of the observation difficulties, the definition of a black hole might diverge.
Demonstrating the actual presence of a black hole may also involve indirect photography and the comparison with the photographs that could be taken of a black hole.
In addition, while the creation of a black hole in the laboratory has been the subject of a plurality of attempts, these have so far not been successful.
Indeed, in theory, the necessary amount of energy is much higher than that likely to be implemented by the human being. Yet, since this theory is not capable of determining:
Trying to reproduce a black hole in the laboratory from this theory could only lead to failure. It should also be noted that the nuclear reactions that take place in space inside the celestial bodies depend enormously on the state (gaseous, solid or dust) and on the density of the celestial body.
Depending on the state and density of the body, nuclear fusion, pycnonuclear, transmutation reactions may occur at very low temperatures even at temperatures comprised between 230 and 2,000° C. (case of brown dwarfs).
Similarly, in black dwarfs, which are celestial bodies that have not yet been directly observed, the possibility of a transmutation reaction at zero degree is considered.
Thus, density is a key parameter of the capacity to be able to create the conditions equivalent to those of a black hole and therefore a black hole.
The Applicants have conducted research in the field of energy production, synthesis of chemical elements (chemical substances) and production of chemical elements such as rare metals, which research has led to the creation of conditions equivalent to those of a black hole and therefore of a black hole. It has been possible to notice this creation by observing transmutation and fusion reactions. This research has been based on the study of the operation of a turbine or reactor type device the implementation of which under particular conditions and the observation of which have allowed defining the invention in the form of a method and then of a device for transmutation and nuclear fusion and therefore for the creation of a black hole. Another object of the invention consists of the applications of these method and device.
According to the invention, the method for energy production and chemical element synthesis is remarkable in that it comprises the following operations:
According to the observations of the Applicants, the reactions in presence are characteristic of those of a black hole. The impact area or point makes up the centre of the black hole and its periphery makes up the accretion area which is a radiation source.
Thus, at said accretion area, a release of heat and the emission of light radiation are observed.
This heat release and these radiation emissions are the consequence of transmutation, nuclear fusion, pycnonuclear and nucleosynthesis, reactions. Pycnonuclear fusion is a fusion in a dense medium. Nucleosynthesis is the consequence of fusions and transmutations.
Nuclear fusion, pycnonuclear, nucleosynthesis and transmutation reactions are promoted by the tunnel effect.
The acceleration of the molecules of the gas and/or of the particles contained in the jet of the second gas or gaseous mixture through a sudden increase in their temperature when the jet comes out into the enclosure results in an increase in the speed of the molecules of the gas and/or of the particles contained in the jet(s) of the second gas by a factor of 3 to 100 depending on the temperature in the enclosure.
The wall of the enclosure is thin, this wall may become transparent and allows seeing with the naked eye the swirling movement of the ionised hot gas around the impact point of the jet (impact point forming the black hole).
This heat and this radiation may be exploited for a plurality of applications.
Thus, according to a feature of the invention, the energy contained in the black hole and its surroundings (accretion area or disc and other areas after the accretion area starting from the centre of the black hole), is in the form of:
According to another feature of the invention, the energy is extracted from the black hole into:
The extracted energy may be used to propel aerial, space, land and maritime vehicles. They may also be used in industrial and/or domestic applications.
According to another feature of the invention, at least one of the following chemical elements Fe, Co, Sb, Sn, Sr, P, S, Ti, Mg, Zn, Al, V, Ti, Ir, Rh, Rb, is synthesised.
According to another feature of the invention, the following effects may be used to extract energy:
According to a preferred yet non-limiting embodiment, the speed of the second gas forming the jet is higher than 30 m/s or higher than 50 m/s or higher than 100 m/s or higher than 150 m/s or higher than 200 m/s or higher than 300 m/s or higher than 400 m/s or higher than 500 m/s or higher than 1,000 m/s. The speed may range up to 5,000 m/s.
These speeds are those implemented at the jet before acceleration thereof.
The impact of the jet of the second accelerated gas on the wall of the enclosure (which enclosure is called reactor or combustion chamber) results in a very significant increase in the pressure on the impact area and its surroundings, which could reach 50 to 1,000 bars (50 to 1,000 Kg/cm2). This may be locally reflected by an increase in the density of the material to values from 10,000 to 20,000,000 g/cm3. This higher density is obtained because of the pressure exerted by the jet.
According to another particularly advantageous feature of the invention, the second gas forming the jet(s) (fresh or hot gas at the jet nozzle outlet) is selected from the following list:
According to another particularly advantageous feature of the invention, the second gas is formed by any other gas or mixture of at least two of the gases listed hereinabove. The mixture of oxygen with another gas gives good results in particular in obtaining the fusion reaction.
According to another particularly advantageous feature of the invention, the material of the enclosure is selected from among thermally and/or electrically conductive metals or metal alloys. These choices are made to promote these reactions.
According to another particularly advantageous feature of the invention, an element made of a material different from that of the walls of the enclosure is positioned at the impact area. This feature allows better managing the exploitation of the obtained reactions by changing the atoms subjected to the jet and thus for example synthesising different chemical elements.
When the materials of the walls of the enclosure undergoing the impact or of the element positioned at the impact area contain chemical elements heavier than iron, nuclear fission reactions of these heavy elements occur.
According to another particularly advantageous feature of the invention, the content of the enclosure undergoes a heating before introducing the second gas or gaseous mixture.
According to a preferred embodiment, this heating is implemented by at least one following method:
By any heating means including electrical means.
According to another particularly advantageous feature of the invention, the electricity for the electrical heating originates from solar panels and/or wind turbines.
According to another particularly advantageous feature of the invention, the first hot gas or gaseous mixture results from a combustion carried out in the enclosure.
According to another particularly advantageous feature of the invention, the enclosure is fed with one or more liquid or gaseous fuel(s).
According to another particularly advantageous feature of the invention, when a combustion is implemented in the enclosure, the jet of second gas or gaseous mixture is brought into contact with the combustion flame are used. The sudden change in temperature is then optimised.
According to another particularly advantageous feature of the invention,
This duct enables the discharge, where appropriate and when desired, of the combustion gases, plasma, etc. . . . .
According to another particularly advantageous feature of the invention, one or more fresh or hot air jet(s) is/are complementarily arranged in the discharge duct for the purpose of feeding another enclosure.
According to another particularly advantageous feature of the invention, the combustion flame is replaced by a hot gas with a temperature higher than 700° C. (for example and without limitation: hot air, hot CO2, hot N2, hot air-oxygen mixture or any other gas or mixture of gases).
According to another particularly advantageous feature of the invention, the temperature of the second gas (gas forming the jet(s)) is lower than the temperature of the combustion flame of the liquid or gaseous fuels in combustion in the semi-open enclosure.
According to another particularly advantageous feature of the invention, the used fuels are fossil or non-fossil fuels, carbonaceous or not, biofuels, in liquid or gaseous or cryogenic or solid form, for example (without limitation):
According to another particularly advantageous feature, the wall on which the impact took place consists of a powder or particles or microparticles of metals or alloys of conductive metals. This structure of the material promotes the desired reactions.
The invention also relates to the device allowing implementing all or part of the above-described method.
According to the invention, the device comprises an enclosure comprising a wall equipped with inlet orifices with,
According to another particularly advantageous feature of the invention, the enclosure comprises at least one inlet orifice for a combustible liquid or solid or gas or for a gas resulting from the combustion of fossil or non-fossil fuels;
According to another particularly advantageous feature of the invention, the enclosure comprises at least one ionised gas or plasma outlet orifice and the combustion gases, when a combustion is carried out.
According to another particularly advantageous feature of the invention, the wall or the element undergoing the impact of the jet is inclined with respect to the axis of the jet.
According to another particularly advantageous feature of the invention, the axis of the jet of the second gas or gaseous mixture is inclined by a given angle with respect to the axis perpendicular to the surface of the impact area of the jet. This inclination contributes to the creation of the desired swirl.
According to another particularly advantageous feature of the invention, the thickness of the metal enclosure is comprised between 0.1 mm to 1,000 mm or smaller than 0.1 mm. The thickness contributes to the reaction by activating the migration of the atoms. A small thickness is preferred to promote the tunnel effect.
The method and the device of the invention may be used for the production of energy, for the propulsion of spacecrafts, for the propulsion of aerial and maritime vehicles, for the propulsion of civil aircrafts.
According to another particularly advantageous feature of the invention, the material of the wall of the enclosure is selected from the following list:
According to another particularly advantageous feature of the invention, the aluminium or the aluminium alloy is coated over its internal and/or external face with a polytetrafluoroethylene (PTFE) coating.
According to another particularly advantageous feature of the invention, a lead-bismuth plate is arranged in the impact area of the gas jet so as to form iridium and rhodium. Indeed, the particular conditions suggested by the operation of the method enable the synthesis of some metals.
The fundamental concepts of the invention have just been disclosed hereinabove in their most elementary form. Other details and features will appear more clearly upon reading the following description and with reference to the appended figures, giving as non-limiting examples, embodiments of a device in accordance with the invention the results of which are provided and analysed. These results constitute proofs of the reactions obtained by the described and claimed method. Indeed, it appears in the data provided hereinafter that in addition to the excess heat observed, chemical elements already present are produced and new elements appear.
It should be noted that videos of said embodiments have also been made.
As illustrated in
The walls of the enclosure 100a are apertured at the lower portion with lateral inlet orifices 102a. These inlet orifices 102a enable air at atmospheric pressure or under low or very low pressure to feed the internal volume with fresh air. The upper portion of the enclosure 100a is provided with a vertical conduit 103a for the discharge to the outside of the combustion gases and/or plasma created by the ionisation of the gases projected before and after percussion produced in the internal volume 101a.
In accordance with the invention, the device Da further comprises a gas supply duct 200a. According to one embodiment, this gas is air compressed between 0.5 and 700 bars by a non-illustrated compressed air supply module. The duct 200a has an inner end equipped with an air projection nozzle 201a and which is positioned in the internal volume 101a of the enclosure 100a. This nozzle 201a projects into the hot gaseous medium composed by the flames and combustion gases 114a a compressed air jet 202a at high speed. This speed is between 30 and 5,000 m/s. The change in temperature contributes to the acceleration of the projected gas jet.
This nozzle 201a is directed towards the lower surface of a wall of the enclosure 100a where a collision occurs. In the impact area 300a of the air jet, fusion occurs where a plasma is created. This impact area is the creation area of the black hole. The inclination of the wall surface where the impact area is located contributes to the desired creation of the ionised hot gas.
According to a preferred yet non-limiting embodiment, the enclosure 100a is made of stainless steel (grade 304 and/or 316), the container 110a of the liquid fuel is made of aluminium or aluminium alloy coated with PTFE or not.
Compressed air can be replaced by:
The observed phenomena and the obtained results during different tests will be described more specifically later on.

As illustrated in
In addition, the duct 112d conveys into the container 110d a combustible gas and opens into the latter by means of a burner 116d which, in association with the igniter 115d, ensures the combustion of the gas and the creation of the hot gaseous mixture 114d in the internal volume of the enclosure 100d. The black hole is created at the same location. According to a preferred embodiment, the materials are also the same.
As illustrated in
Thus, the device De comprises an enclosure 100e defining, thanks to its metal walls, an internal volume 101e in which a liquid fuel 111e is present in the lower portion. This liquid fuel is supplied through a supply duct 112e. The enclosure 100e is equipped with an electric igniter 113e. The combustion of the fuel creates flames and gases 114e in the internal volume 101e of the enclosure 100e.
A lateral wall of the enclosure 100a is provided with a horizontal duct 103e for the discharge to the outside of the combustion gases and/or plasma (created by the ionisation of the gases before and after percussion of the wall) produced in the internal volume 101e.
The device De further comprises a compressed air supply duct 200e. This air is compressed between 0.5 and 700 bars by a non-illustrated compressed air supply module. The duct 200e has an inner end equipped with an air projection nozzle 201e and which is positioned in the internal volume 101e of the enclosure 100e. This nozzle 201e projects into the hot gaseous medium composed by the flames and combustion gases 114e a compressed air jet 202e at high speed. This speed is between 30 and 5,000 m/s.
This nozzle 201e is directed towards the internal surface of a wall of the enclosure 100e. The impact area 300e of the air jet on the wall is in the axis of the duct 200e and is the creation area of the black hole.
As illustrated, the ducts 200e, 112e and the electric igniter 113e open out at a lateral wall of the enclosure 100e arranged in opposition to the lateral wall of the enclosure provided with the horizontal duct 103e.
The suggested design is closed in that the inlet air comes exclusively from the duct 200e which conveys the compressed air. Furthermore, it is simpler in that the fuel 111e does not have a dedicated container but is stored directly in a volume defined by the lower walls of the enclosure 100e.
As illustrated in
These hot gases may also contribute to heating of a first gas or gaseous mixture in another enclosure (not illustrated).
As illustrated in
This supply module comprises a tank 400 storing the mixture M1. Said reservoir 400 comprises an opening 410 at the upper portion and is equipped with:
These two ducts join into a common duct 440 which links with the enclosure of one of the above-described liquid fuel devices.
The outlet duct 420 is associated with an adjustable variable flow pump 421. Each of the return duct 430 and the common duct 440 is equipped with a regulating and shut-off valve 431 and 441.
The return duct 430 enables the return to the reservoir 400.
According to a preferred embodiment, the composition of the mixture M1 is as follows:
According to other embodiments, the ethanol is replaced by methanol, propanol, butanol or by another fuel.
This module comprises two equivalent tanks 500 and 600 equipped in the same way as the above-described tank 400 and whose common ducts 540 and 640 join into a unique duct 650 to form the mixture M1 before feeding the enclosure of one of the above-described liquid fuel devices.
Thus, the tank 500 stores ethanol (with a concentration higher than 96%) and comprises an opening 510 at the upper portion and is equipped with:
These two ducts join into a common duct 540.
The outlet duct 520 is associated with an adjustable variable flow pump 521. Each of the return duct 530 and the common duct 540 is equipped with a regulating and shut-off valve 531 and 541.
The tank 600 stores a mixture M2 and comprises an opening 610 at the upper portion and is equipped with:
These two ducts join into a common duct 640.
The outlet duct 620 is associated with an adjustable variable flow pump 621. Each of the return duct 630 and the common duct 640 is equipped with a regulating and shut-off valve 631 and 641.
According to a preferred embodiment, the composition of the mixture M2 is as follows:
The obtained ignition temperature of M1 is higher than the ignition temperature of ethanol (96%) alone which is higher than 40-50° Celsius.
Management of the supply of a device as described hereinabove implemented in the form of an aircraft reactor may be as follows:
The fresh air composing the second gas is under pressure between 0.5 and 700 bars. The air jet outlet is higher than 10 m/s or higher than 20 m/s or higher than 30 m/s or higher than 50 m/s. The speed may range up to 5,000 m/s.
The Applicants have taken photographs
These photographs are reproduced in black and white in
Photograph 10 illustrates during a phase of stopping the top of the device, for example Da, where the enclosure 100a keeps the colour of its material.
Photograph 11 illustrates during operation the change in colour of the enclosure or reactor visible from the outside. Under the action of the heat, the enclosure 100a reddens until whitening. In addition, at the impact point where the black hole is formed, a darker area 300a′ appears at the external surface.
As illustrated, the darker zone 300a′ and the light halo 301a′ surrounding it reproduce the distinctive elements of a black hole, namely its centre and its accretion disc.
Photographs a, b, c, d, e, f, g, h of
The first 6 photographs (a to f) are real photos of the black holes created during the operation of the device. These are real images and not rendered images. The black hole in (a) is obtained with CO2 alone as jet gas. The black hole at b is obtained with air as jet gas. The black holes in C, d, e and f are obtained with a CO2+O2 mixture as jet gas. The last two images (g and h) are images of the M87 black hole located in the M87 galaxy and filmed in 2019 by the EHT (Event Horizon Telescope) telescope.
The Applicants have noticed that an excessive heating in the accretion area resulted in a melt-down of the enclosure at said accretion area. This melt-down occurs at the accretion disc and is illustrated by the photograph of
In addition, they have carried out a plurality of readings enabling a better understanding of the different contributions of the invention, in particular on the plant illustrated by the photographs of
The composition of the combustion gases and/or of the plasma at the outlet the enclosure or reactor is as follows:
This table shows the obtained upper temperature. The Applicants estimate that 1,500° Celsius are possible at the output. Nevertheless, a temperature substantially higher than 300° Celsius is estimated inside the enclosure.
The electrical resistance of the gases at the outlet of the device has also been measured. The measured resistance ranges from 10 to 500 KOhm, which proves the presence and therefore the formation of plasma. Hence, the electrical resistance of hot air measured at the same temperature without reaction as defined in the invention is infinite under these conditions.
The Applicants have carried out a plurality of analyses in order to determine the emitted elements or products and those destroyed during operation of the device.
Several analysis means have been implemented, including an X-ray fluorescence spectrometer which has been used to analyse several areas of the walls of the enclosure.
Before operation of the device, the analyses carried out on 5 different areas identified from 29 to 33 have given the following results:

After operation, the Applicants have noticed the creation of a reaction powder or ash inside and outside the enclosure.
The powder or ash recovered inside the enclosure is illustrated by the photograph in
The ash formed inside the enclosure resulting from contact between the plasma and the upper walls of the enclosure has the following composition:
This ash has been obtained in the chamber with ethanol as fuel (97% at 6 kg/h) and a jet of compound gas (120 l/min air combined with 80 l/min oxygen).
After operation of the device, the analyses of the ash present at the external surface of the enclosure in the accretion area as it appears in the photograph in
This ash has been obtained at the external surface of the enclosure with ethanol as fuel (97% at 6 kg/h) and a jet of compound gas (air 80 l/min combined with oxygen 20 l/min).
The analysis of these internal and external ashes allows noticing that:
the proportion of some chemical elements (substances) already present before operation changes (the proportion of Iron increases), and bodies of chemical elements (substances) that were not present (such as aluminium, cobalt, magnesium) before operation have appeared.
This demonstrates the presence of nuclear fusion and transmutation reaction corresponding to the reactions that might be found in a black hole. There is fusion because one could notice the chromium atoms being transformed into iron atoms by atomic weight increase and transmutation because one could notice the nickel atoms being transformed into iron atoms by atomic weight decrease.
An analysis of other areas of the enclosure and those already identified has been carried out and gives the following results:

These results have been obtained with ethanol as fuel at 97% 6 g/h and a gas jet composition with air (80 l/min) oxygen (20 to 40 l/min) and carbon dioxide (0 to 20 l/min).
Herein again, the proportion of some chemical bodies already present before operation changes, and chemical bodies that were not present before operation have appeared.
This demonstrates the presence of nuclear fusion and transmutation reaction corresponding to the reactions that might be found in a black hole.
During operation of an embodiment of the device where the wall of the enclosure or reactor has been pierced under the action of fusion, the Applicants have analysed two faces of the residual portion removed from the wall, which portion is illustrated by the photograph of
The results of these analyses are as follows:

It appears that if the composition on the external face of the enclosure almost looks like that of a 316 grade stainless steel, the composition analysed at the internal surface reveals different proportions and new components, demonstrating the implementation of fusion and transmutation reactions.
These results have been obtained with ethanol as fuel (97% at 6 Kg/h) and with a gas jet composed of air (120 l/min) and oxygen (80 l/min).
These first observations have led to specifying the analyses of the different elements (powder, residual portion originating from the hole) appearing after operation of the device in particular by varying the oxygen flow rate from 20 to 60 l/min.
The different elements analysed have been referenced as follows:

This synthesis shows the evolution of the percentages of the different elements already constituting the device (new reactor column) as well as the presence of new elements.
The formation of iron, the disappearance of chromium, nickel, the formation of some chemical elements such as magnesium, cobalt, titanium, phosphorus, sulphur demonstrate the presence of a fusion and transmutation reaction inside the enclosure.
The Applicants have also noticed that, during operation, particles have been emitted by the outer surfaces of the so-called reactor enclosure of the device. This emission has been detected and analysed by detecting traces of particle impact on a plastic material of the polymethyl methacrylate (PMMA) type, so-called acrylic glass.
The impact trace monitoring protocol is as follows:
As illustrated in
The impact traces may be observed with a paralux and Solomark microscope. An impact hole image is illustrated by the photograph in
These impacts have been analysed with a spectrometer on the front face and on the rear face of two plates subjected to the impacts.
The following tables give the results of these analyses.
It should be noted that a non-impacted PMMA plate is composed of a mineral and metallic substance of calcium (Ca) at 500 PPM (parts per million).
Since chromium and nickel are not detected, it could be concluded that the increase in iron concentration is not related to a phenomenon of evaporation of the other elements.
The Applicants have also analysed the radiations emitted by the external walls of the so-called reactor enclosure during operation by means of a neutron and x-ray gamma detector (R60N with an N10 probe) as well as by means of a beta, gamma, etc., radiation detector.
Measurements of the emitted radiation (beta, gamma, x-rays and neutrons) show values lower than 0.3 microsieverts per hour. Thus, no hazardous radiation is detected outside the reactor
With regards to the analyses hereinabove, the Applicants have imagined an application of the device of the invention for the purpose of synthesising iridium and rhodium.
This synthesis is done starting from a lead-bismuth plate with a lead concentration of 90% and a bismuth concentration of 10% arranged in the enclosure or accessible from the latter so as to subject it to the jet of the second gas under the following conditions: used fuel: Ethanol at 97% at 6 Kg/h and jet-forming gas composition: Air (80 l/min)+oxygen (20 l/min).
To implement this application, the wall of the enclosure has been pierced at the impact area of the jet and the lead plate has been arranged to seal off the created hole so that the jet of the second gas is brought to impact said plate which is associated with a mounting for holding in position to hold it in place on the external surface of the enclosure above the hole. This set-up is illustrated by the photographs in
After operation of the device, under the effect of the bombardment, the lead-bismuth plate melts down and gives a plurality of samples.
The analysis of these samples by spectrometry gives the following results:

Thus, it appears that rhodium and iridium have actually been synthesised from the bombardment implemented by the device of the invention of a plate of lead associated with bismuth. Rhodium and iridium are formed by transmutation of lead and bismuth. The concentration of the produced rhodium (0.297-0.44%) or an average of 3,700 g/tonne of sample is 2,466 times higher than the average concentration of rhodium in natural ores (1 g/tonne of minerals). The concentration of the produced iridium (6.16-8.42%) or an average of 73,000 g/tonne of sample is 48,600 times higher than the average concentration of iridium in natural ores (1 g/tonne of ores).
The details of the twelve results of the analysis carried out on twelve faces by spectrometry are given hereinbelow.

It appears in these results that the device of the invention produces chemical elements at a concentration higher than that which is found in natural and therefore without extraction.
It should be understood that the method and the devices that have just been described and shown hereinabove have been disclosed for the purpose of disclosure rather than limitation. Of course, various arrangements, modifications and improvements could be made to the examples hereinabove, yet without departing from the scope of the invention.
