Philo Taylor Farnsworth
Not Fusion to Hot Fusion – Forgotten:
The sixty-year-plus fusion failure of physics
“In the 1930’s scientists, particularly Hans Bethe, discovered that nuclear fusion was possible and that it was the energy source for the sun. Beginning in the 1940’s researchers began to look for ways to initiate and control fusion reactions to produce useful energy on earth.”
Wiki: Philo Taylor Farnsworth, American inventor and television pioneer, is perhaps best known for his 1927 invention of the first fully functional all-electronic image pickup device (video camera tube), the “image dissector”, as well as the first fully functional and complete all-electronic television system. He was also the first person to demonstrate such a system to the public. Farnsworth developed a television system complete with receiver and camera, which he produced commercially in the form of the Farnsworth Television and Radio Corporation, from 1938 to 1951, in Fort Wayne, Indiana.

Forgotten Episode in “Hot” Fusion History

Eric Dollard is an electrical engineer who has done remarkably exhaustive historical research and experimental verifications of scientific claims made by Nikola Tesla a century before. It was through Mr. Dollard that we learned about a forgotten chapter in the art of controlled thermonuclear fusion like no other. In fact, those who read this article may be shocked to learn the real truth about one specific “hot fusion” project from 1962 until 1967.
The reality of anyone controlling fusion reactions … and reaching self-sustaining reaction stage would sound bizarre to anyone familiar with the historical publications. Of all the venture projects chasing after the hot fusion Grail one group of researchers looked directly into Nature’s brilliant face and saw her sparkling eyes. Mr. Dollard’s research on unusual electron tubes led him into an exhaustive study of several vacuum tube designs patented by the father of electronic television: Dr. Philo T. Farnsworth. There he found the forgotten gem.
PHILO T. FARNSWORTH
Among the incredibly prolific patents of Dr. Farnsworth are two working designs for achieving practical nuclear (“hot”) fusion. Dr. Farnsworth is the original designer of true electronic television. He had to develop the entire system of electronic television with all its parts. Image dissectors, pulse transmitters, synchronizing oscillators, synchronous scanning, image analyzers, receivers, and special cathode ray tubes … Farnsworth conceived, designed, and hand built each of them.
The technological demands of his complete television system required the development of very special electron tubes from start to finish. Each component demanded new tube designs and operational theories. In fact, examination of the Farnsworth patents reveals nothing but novel tube designs without contemporary equal.
Existing multielement tubes could neither match the stringent power demands or frequency requirements of television. Therefore Farnsworth developed numerous unusual tubes to make his television oscillators, receivers, and transmitters more efficient. No existing technology could match the performance characteristics of his UHF oscillators, electron multipliers, and cold cathode signal amplifier tubes when he patented them.
Farnsworth designed numerous highpower UHF tubes. Notable among these designs were cold cathode devices (some of which employed soft radioactive materials), photomultipliers, multipactors, IR imaging tubes, image storage tubes, and image amplifiers. Each was a marvel of originality and inspiration. But the multipactor was a true wonder.
The multipactor design employs two opposed concave cathodes and a central series of cylindrical anodes. Noise surges generate and sustain powerful tunable oscillations within the multipactor when voltage is simply applied to the cathodes and anode. The multipactor utilizes photomultiplier effects to supply electrons. Multipactor performance borders on the anomalous, approaching “impossible” efficiency coefficients.. His success was followed closely by engineers from every military and industrial group. Fullscale research addressed the multipactor efficiency “problem”. Reports from the time period may be easily secured for study and reevaluation.
Farnsworth continued to be a prolific designer of very unusual electron tubes before and after World War II. Casual examination of his patents continually proved the genius behind the legend. Dr. Farnsworth explored new alternatives and designed radically new concepts into a series of electron tubes which became as heralded as his development of electronic television. Each development produced in own species of anomalous phenomena These were each utilized and compounded in his successive developments. The patent record tells the story best.
PLASMOIDS AND VIRTUAL ELECTRODES
While testing high power UHF tubes Farnsworth discovered an anomalous self-focussiog space charge phenomenon. These space charge plasmoids glowed all the more brilliant with increasing application of voltage … a control characteristic. He named these pointplasma phenomena “poissors”.
“Poissors are brilliant spacesuspended plasmoids of starlike appearance. When Dr. Farnsworth operated his multipactors the poissor phenomena manifested themselves with special brilliance. Electron optical focusing concentrates ions just as mirrors concentrate light. Early Farnsworth multipactors utilized twin opposed concave cold cathodes.
The design feature of concave electrodes was a radical departure in the world of electron tube designs at the time. Most electrodes of the day were simple planar surfaces. The concaves permitted the rediscovery of electron optics … a phenomenon originally witnessed by Sir William Crookes and forgotten. Students are directed to the Crookes tube with its concave cathodes.
Farnsworth multipactors and cold cathode discharge tubes produce optically focused “poissors” and exhibited all the responsecontrol characteristics later sought by plasma physicists in their race toward achieving hot fusion. Controlresponsive poissors would shrink in size, increase in ionic density, and produce more brilliant light with increasing voltage application.
Notably discovered in 1936, the poissor phenomenon made a new breed of electron power tubes and plasma devices possible. The existence of these mysterious suspended plasmoids stimulated Farnsworth’s research toward the refined use of electron optics. His refinement and use of the newly manifested phenomena produced remarkable performance efficiencies in UHF and SHF applications. In their unprecedented spherical geometries the Farnsworth tubes proved incredibly efficient and long lasting.
Virtual electrodes could influence electron behavior in power tubes. Ions could be bound in small plasma points (poissors) exhibiting stability in ionic multilayers and sheaths. Poissors could absorb and store energy: an aspect which deeply impressed Dr. Farnsworth. The time for their retrieval from the archives of the anomalous drew close.
By 1953 he had conceived of a means for using the poissor phenomenon to produce controlled nuclear fusion reactions.. The patent record shows that Farnsworth achieved the goal. Yet, there are far more deeply entwined reasons why few have ever heard of Dr. Farnsworth’s contributions and achievements besides the academic censure of this possibility.
In 1959 H. S. Geneen (Raytheon) invited Dr. Farnsworth to address the ITT board of directors on controlled nuclear fusion. Against the verbalized misgivings of the AEC this lecturepresentation was given. Shortly thereafter a preliminary test on the Farnsworth “Fusor” was performed in a small ITT basement laboratory. His first design for a hot fusion reactor was realized in 1959. ITT monitored all the research and brought its own supervisors into Farnsworth’s team.
Virtual poissor plasmoids of deuterium would be isolated, shaped, confined, treated, balanced, or moved without magnetic confinement. Farnsworth’s solution to reactant confinement was elegant, simple, inexpensive, and highly efficient. He designed a new and dramatically original tube which he named “The Fusor”. This was the summation of a lifetime’s discoveries and development. I believe it is the most advanced electron power tube ever designed.
The Fusor is a device which produces controllable hot fusion reactions and does not utilize magnetic confinement. The design is a radical departure from all the designs of its time frame. The Fusor is comprised of a spherical anode which concentrically surrounds a cathode. A plurality of ion guns are mounted on the anode exterior in spherically spaced and diametrically aligned relationship so that their beam axes intersect at the cathode center. Ions from the guns are propelled and focused into the center of the cathode. This establishes in the cathode interior a series of concentric spherical sheaths of alternating maxima and minima potentials: the “virtual electrodes”.
Ions never touch any surfaces in these tubes. Magnets are never needed. The ions which “fall” into the center-most virtual electrode have fusion energies, and are contained at a density sufficient to produce fusion reactions. Charged particles are literally compressed into the required density in the central region by the process of inertial containment … a term in the art which Farnsworth first coined.
Oscillating ions are concentrically gathered in a series of charge sheaths which conform to the optically focussed fields and which represent the distributed kinetic energies of ions in the poissor. Potential escaping prereactive ions encounter successive electrostatic repulsions until they are forced back into their center. The Fusor System proved stable throughout its forgotten seven year research history.
With developed potentials of sufficiently high magnitude the fusion reaction can be sustained and controlled at will. Furthermore, fusion energy produces powerfully escaping nuclei which perform work against the anode field. This ionic pressure augments the applied field and appearing as a dramatic surge in field strength: one that may be directly harnessed and used in external loads as electrical power.
The fears of a “runaway reaction” were handled in the natural equilibrium maintained by the poissor core structure … as stars self maintain their output by expanding and reducing plasma density. Poissors were found to be remarkably resilient and resistive to instabilities. Farnsworth solved the confinement and conversion problems in one design. The field symmetries and process involved in achieving this variety of hot fusion seems macro-analogous to those characteristics being now explored in “cold” fusion.
On October 8, 1960, the Mark I produced a steadystate neutron count when deuterium was admitted into the device with very low power application. The central feature during these tests was not the neutron count itself. What was sought in these tests lay in the control of the reaction under increasing power application. Farnsworth established and charted increasing neutron counts with increasing application of electrostatic power. It is suggested that the reader obtain and study copies of the Fusor (patent 3,386,883).
With deuterium gas in the Mark II Model 2 Fusor a count exceeding 50 Mneutrons cc/sec was recorded at 80 Kv. and 30 rnA. input. This device produced 1.3 G-neutrons/sec. in a sustained reaction for more than one minute. These reactions were stable, completely under the operator’s control, and could be repeated.
On October 5, 1965 the Fusor Mark IIModel 6 was tested. A reconfigured, highprecision ion gun arrangement produced l Gneutrons cc/see at 20 Kv. and 1 mA …. a record achievement. On December 28, 1965 tritium was admitted into the test chamber … producing 2.6 G-neutrons/sec. at 105 Kv. and 45 mA.. With a mixture of tritium and deuterium on the very next day Dr. Farnsworth’s team measured and recorded 6.2 G-neutrons/sec. at 170 Kv..
The Mark III Fusor produced startling high records in quick succession. By the start of 196.5 the team was routinely measuring 15.5 G-neutrons/sec. at 150 Kv and 70 mA.. The final problem to be tackled involved the poissor itself. Self-containing and tightly layered, the fusion poissor would not admit fuel into its core once the reaction had begun. It must be remembered that this Fusor was softballsized. A Fusor having a diameter of just one meter would permit greater ignition power for a smaller time period … while multiplying output power volumetricallv.
SUSTAINED FUSION REACTION
Dr. Farnsworth reported that his team achieved a selfsustaining reaction on several occasions … and could repeat the effect. He once invited his wife to watch a testrun of this feat. As power was applied to the Fusor the neutronreading meter achieved a steady threshold and there remained … until a slight increment of power was applied. Then the needle went off the scale. Dr. Farnsworth cut the applied power … but the needle remained in place for thirty seconds or more as the reaction continued.
ITT gradually absorbed the entire project. All related patents were assigned to ITT as success was achieved in steady steps. While steady progress was being achieved at a modest cost (examine the photographs), lTT was being influenced by powerful professionally hired “opinion makers” to drop fusion research. Suddenly even Wall Street analysts were publishing their “concerns” for ITT and its absorption of the Farnsworth subsidiary. Farnsworth himself was made the focus of every corporate death-word. These outlandish accusations indelibly remain in newspapers from the time period.
The suppression and assassination of technology is historically the response of frightened competitors … response to an impending breakthrough which might wipe out competitors. Crowd pleasing philanthropists become predators when possible usurpers appear.
Piercing voices appeared from everywhere against Farnsworth. A large reception at the Waldorf was astir with executive unrest concerning the Farnsworth research project While dressing, Farnsworth suffered a mild stroke. The AEC was mounting the nuclear fission race and the “antifusion” race simultaneously … and using every tactic to achieve total dominance of the energy field. He was relieved of his research project
The effect of such disappointment upon those whose lives and hopes are involved in such research is never superficial. In them ride the dreams of whole societies and futures. Those who harm such individuals do not survive in the long run. The price for the dreamer, however, is dear. Dr. Farnsworth suffered another stroke on a plane ride back home. He then retired to convalesce.
During his recuperative period at home he decided that the Fusor should be developed to its complete perfection. ITT had formally and publicly stated that the Fusor was a “deadend”. Farnsworth thought that since this was their attitude, he might have a try at reobtaining his patents. He therefore contacted ITT and honestly announced his intentions. The answer was negative and impersonal … a curious response for a device which was a “dead-end”… given to such an eminent personage whose inventions maintain the entire ITT operation to this day.
In quick successions, ITT asserted its complete ownership of all Fusor applications in the future. ITT warned Farnsworth that it would dominate all Fusor research forever … despite its “unfeasibility”. ITT then cut all formal financial ties with Farnsworth and left him virtually bankrupt. ITT now holds the Farnsworth patents … and bears the social debt of responsibility for suppressing Fusor technology.
In July 1969 Farnsworth built a small Fusor lab in a Brigham Young University cellar room. With purchased equipment from ITT he continued his research with generous University support. Creditors were crowding him on every side. During this time an offer came to him from SONY. He felt unable to continue. Physically ill for a long time and emotionally scarred, he died from pneumonia in 1971.
The aim of my article is not simply to reexpose mere technical facts … but to explore deeper issues of science and society. Hot fusion was achieved, scrutinized, assassinated … and suppressed. It is remarkable that few individuals in the fusion research teams across the world are even aware that their goal was realistically attained. The device which attained this feat was elegantly simple, but the movements of these social energies must first be clearly understood.
Several questions now demand simple answers. What names were behind the obvious and deliberate attack on Farnsworth’s Fusor project? How have these forces managed to keep Farnsworth’s work completely suppressed? How is it that ITT never reexarnined and duplicated the Fusor Project? Why are outrageously huge funds yet being supplied for Tokamak projects? Are these grant mixappropriations deliberate or are they the inertial results of forgotten knowledge? Is the synthesis of artificial social myths accumulating ignorance among those who originally produced them?
Those who are familiar with the lure of science archives understand very well that more potential technology lies dormant than is currently addressed, discussed, or implemented. Much of modern scientific research is the weak echo of work already completed within the last century. There are those who prefer to collect grants and assure themselves of bureaucratically “safe” experiments rather than ris} their yearly salaries on radically new scientific ventures.
Survivalism among academicians is no less savage and ruthless than among other groups with whom we more often associate base behavior. There are those who use projects in “throw away” fashion just to survive. There are those whose jaded personalities have taken a survivalistic stance and already accept that hot fusion is a deadend … but a steady income.
This kind of pessimism in the scientific field promotes status-quo technology and eventually blocks He paths toward adventure arid discovery wherever and whenever it can. Unfulfilled minds become pessimistic. Unchecked pessimism becomes maliciousness.
The true and original artists of contemporary science are difficult to name except for those in radical technological ventures. It is rare today to find that kind of explosive scientific development which absolute saturates Victorian journals between 1880 and 1910. Yet we recognize that our Victorian mentors were responsible for the paths upon which we are now traveling.
More radical discovery and technology were forged during the Victorian time period than is actually engaged today. Science also seems to have great difficulty in making simple assertive statements as did our forebears … who produced a far greater weight of accomplishments. Science speaks of “statistical agreement” and “reasonably close correlations”. Not one individual is willing or able to simply say “yes” or “no”.
I was not surprised when scores of noncommittal authority pleasing academicians came forward to refute new hydrogen energy. It was rather like watching reflexive behavior in laboratory animals. I believe the next regulatory step will be to ban the production of these designs and devices outright. We should be prepared for the corporate onslaught. I personally believe that we should take our options as global citizens … and cultivate the new technology among disadvantaged nations.
One observes that the scientific community automatically digests potential possibilities whenever new unexpected discoveries manifest themselves. This again is that rigid kind of scientific dogmatism which holds forth the graven image of “the model” before the truth. The cultivation of new discovery is an unknown art in our day … except among a rare few.
What is “unexpected discovery”? Is it not the piercing reminder that theoretical models can never replace or truly confine natural reality? Yet there are those who have inwardly replaced reality with the model … and defend the model to the death. The bright light of any natural anomaly or unexpected discovery is hated precisely because it is feared. The model for many scientific personnel is secretly their “lifeline” … their mantra. These personalities are easy to identify. Unfortunately, in positions of power, they are formidable dissuaders of new technologies.
Newly recognized phenomena and unexpected anomalies distinguish natural reality from all models. The trained scientific historian scours the sometimes rotting refuse of discarded periodicals with particular regret In these discarded stacks lie observations of enormous scope which were faithfully committed by their discoverers to the academic storehouse in hopes that these would be honored, evaluated, and admixed into newer awareness.
Why is unexpected discovery feared and hated by financial dynasties ? New technology spell. ruin for those whose statusquo policy has eliminated them from the competitive race. Most very wealthy individuals are never passionate Makers. Neither are they true philanthropists. While removing the future on the one hand they make publicly acclaimed contributions on the other. The banal misuse of powerful positions wields control to stop progress.
Regulating what discoveries are “permissible” precedes limiting “what can be known”. In other words the control of discovery precedes the control of knowledge. The control of knowledge precedes the control of awareness. Mod of the world’s greatest scientific potentials lie tragically forgotten in libraries throughout the world. It is indeed remarkable to discover forgotten scientific history in the journals and patent registers because such hinds” often answer current technological problems from a more fundamental level than is imagined. The libraries themselves are being systematically gleaned and old “inadmissible” knowledge is being eradicated.
Several purposes underscore this paper. The first is recounting the story of Dr. Farnsworth’s Fusor. The second concerns knowledge forgotten. We must never take the study and preservation of archival records lightly. The third aim encourages realization concerning “undefeatable” problems: they are intended to stop our progress along false paths. The fourth purpose lies in understanding the social ramifications of social dreams, new energy, new technology, and the corporate regulators of these social energies. The fifth is purely scientific: new hydrogen energy has produced tiny poissors in the solid state (Iyengar, Srinivasan).
The advent of new hydrogen energy research represents a natural phenomenon of unprecedented magnitude … a sociological event. Here we find ourselves in possession of devices which operate on tap water … and which produce prodigious amounts of heat with insignificant electrical stimuli! The need for palladium metal is not always a strict requirement … titanium and even nickel suffice under certain conditions
A mystical belief of mine deals with the suppression of truth by corporate regulators … and the global consequences of such suppression. Discovery itself is a phenomenon. Discoveries are granted as tools of survival against future needs on behalf of our race.
Of discovery I may say that suppression and manipulation results in an unstoppable reaction … the frightening release of newer, simpler technologies in every corner of the world. This phenomenal dispersion so assaults wouldbe controllers that no one regulator may ever seize, quench, or destroy the new technological species.
There are new discoveries to be made everywhere … they never cease appearing. As stars which appear in the blackness of space, so too the miracle of discovery endlessly manifests. This new energy revolution is itself a phenomenon … and win yield to those who pursue it the promise fulfilled.
“…Farnsworth, who also invented a nuclear fusion device later in his career, predicted HDTV and solid-state flat-screen technology in a 1957 interview: “[W]e think we can eventually get in excess of 2000 lines instead of 525 and do it on an even narrower channel which will make for a much sharper picture. We believe in the picture-frame type of a picture, where the visual display will be just a screen. And we hope for a memory, so that the picture will be just as though its pasted on there.”
