FLOYD SWEET'S VTA UNIT
by Walt Rosenthal
The Vacuum Triode Amplifier (VTA) invented by Floyd
Sweet consists of two ferrite magnets and two to four
coreless wire coils. It is self powered in the pre-
ferred configuration and produces in excess of one KW
of 120 VRMS 60 HZ power in the form of energy that
resembles electricity. This energy is referred to as
negative energy. The VTA development history, its
anti-gravity characteristics, negative energy proper-
ties, and some of the personalities involved are dis-
This is a story of Floyd Sweet's trials and tribulations
involving a mystery wrapped in an enigma. God revealed to Floyd
sufficient information to build a machine to provide energy that
resembles electricity. However, God did not provide solutions to
the frustrating string of problems that would surface in convert-
ing the idea into a working device. There are several people in
this story that have provided help and some who have hindered.
When Tom Bearden met Floyd, the device Floyd had developed was
producing a few watts of alternating current at 28 volts. Tom saw
in Floyd's device the physical embodiment of a principle he had
theorized many years before. Tom had never designed or con-
structed a physical device to access this elusive energy source.
Tom's name for the extraction process is 'Four Wave Phase Conju-
gate Mixing'. The energy source is the intense non-cohered energy
that is thought to be present everywhere in the universe. Various
researchers through the years have given this energy different
names, such as "Zero Point Energy", "Gravity Field Energy", "Rad-
iant Energy", and others.
Tom Bearden gave Floyd's device the name "Vacuum Triode Ampli-
fier" or VTA. The machine provides a small amount of its output
fed back to the equivalent of a grid which gates or coheres a
large amount of energy which appears at the device output termi-
nal as something that resembles electricity! Negative Electrici-
This energy can be utilized by devices designed to convert
electricity to light, heat, or mechanical work or anything else
for which normal electricity is used. The properties of this
energy, although superficially resembling the 120 VRMS 60 HZ
power we normally use, are unique and sufficiently different from
conventional electricity, so that it should be classified as an
entirely new energy form. It will require careful extended study
by a wide range of people in order to document its properties in
the manner scientists have done with conventional electricity.
Tom Bearden refers to this energy as negative energy, and he
states that negative time must be utilized. In negative time
according to Bearden, gravity is a repulsive force.
Floyd's experiments demonstrated that the VTA loses weight in
proportion to the amount of generated "Negative Energy". This was
carefully documented by Floyd on a kitchen scale. The machine
weight was observed decreasing with increased load in a quite
orderly fashion until a point was suddenly reached when Floyd
heard an immense sound, as if he were at the center of a giant
whirlwind but without actual air movement. The sound was heard
by his wife Rose in another room of their apartment and was heard
by others outside the apartment. The experience was very fright-
ening and the experiment has not been repeated.
Some observers of the light emanating from ordinary 120 volt
100 watt incandescent bulbs powered by the VTA claim the light is
different, softer, than normal incandescent light. The VTA
magnets and coils when powering loads of over a kilowatt become
cold and temperatures of 20 degrees Fahrenheit below ambient have
been observed. Similar reports of below ambient temperature of
energy machine components have been reported by other inventors,
such as John Bedini and John R.R. Searl.
When the VTA output wires had been accidentally shortened,
first an extremely brilliant flash occurred. When the wires in-
volved were examined shortly afterward, they were found covered
with frost. Unfortunately this also caused the VTA magnet to
fracture and the machine ceased operating. In one instance the
machine operation ceased during a local earthquake. The physical
shacking was not believed to be sufficiently severe to disrupt
the machine magnet/coil relative placement or physical shock to
the magnet such as a hammer blow might impart. The best specula-
tion is that the machine was affected by the intense electromag-
netic pulse known to originate from earthquakes.
Conventional instruments used to measure volts, amps, or watts
appear to correlate machine output as coupled to loads, but only
up to approximately 1 KW; above that value they may indicate zero
or some other value not related to the known actual load.
Floyd's attempts to use conventional electrical design formu-
las relating number of coil turns, amp turns on drive coils, and
any other parameter to predict observed outputs have all resulted
in failures with calculations. Empirical formulas based on
actual tests have been documented.
Observation of machine output voltage of approximately 120
VRMS while the load was changed in 100 watt increments from 100
watts to 1000 watts has shown no observable output voltage
change, which suggests an extremely low internal equivalent
impedance. The 20 gauge magnet wire in the output coils consist-
ing of several hundred turns has significant DC resistance which
is not correlated with the unvarying output terminal voltage at
different loads. It is speculated that this energy does not
travel within the copper wire or its passage through the copper
wire does not generate a voltage drop- a most useful feature when
transferring energy from one place to another.
One frustrating aspect of the VTA has been its failures,
evidenced by the output voltage slowly decaying to zero over a
few seconds or minutes. There also has been spontaneous in-
stances of the voltage rising above 120 VRMS as observed by the
increased lamp load bank brightness. The volt meters, ammeter,
and power meter did not correlate with the brightness change
except when the machine would the fail to produce any power.
Many times the VTA was normally left on powering a lamp load
bank 24 hours a day. During a period of time when it appeared to
be functioning properly all day long, Floyd got up at 3:00 AM to
go to the bathroom. As he walked past the room where the VTA was
located, he noticed that the lights appeared dim. He measured
the voltage at 70 VRMS. Being tired at the moment, he returned to
bed. The next morning when he rose, the voltage was back to the
normal 120 VRMS and stayed there all day. The next night Floyd
got up at 4:30 AM. The voltage was measured at 85 VRMS. Floyd
returned to bed. The voltage was normal the entire next day.
A possible clue to this anomaly has appeared in an article by
E.W. Silvertooth title 'Motion Through The Ether' where Silver-
tooth describes a dual path laser interferometer experiment that
conclusively demonstrated the presence of an ether that flows
through our portion of the universe at greater than the speed of
light with its vector in the direction of the constellation Leo.
Floyd's VTA may be orientation sensitive to this ether velocity
The VTA consists of two 4" X 6" X .5" grade 5 or grade 8
ferrite magnets spaced 3 inches apart in the attractive orienta-
tion, with the output and drive coils in between. The output
coils are wound with 20 gage magnet wire. Their axis is parallel
to the magnetic lines of force between the two magnets. The two
drive (or excitation) coil axes are positioned at 90 degrees to
the output coil axis. The VTA excitation coils may be driven by
the VTA output voltage or a separate sinewave oscillator source.
The "SECRET" to the machine is the process that "conditions"
the magnets. This conditioning process determines the output
frequency and also prepares the machine for operation. The same
machine could be just as well "told" to output 50 HZ or 400 HZ.
The conditioning technique is so novel, it is doubtful anyone
would ever guess how it is done.
Oscilloscope observation of the VTA output voltage waveform
shows an apparently perfect sinewave that is not phase locked to
the local 60 HZ powerline voltage.
The VTA can be started by momentary connection of a 9 volt
battery to the drive coils when the machine is operated in the
self-powered mode. The operation is stopped by momentary inter-
ruption of power to the power coils.
The VTA "likes" to always see a minimum load of 25 watts.
Electrical shock to humans from the VTA may be more damaging
than contact with a 120 VRMS 60 HZ conventional powerline volt-
age. Floyd has accidentally had VTA current pass from his thumb
to his smallest finger. It appears to freeze the flesh and was
extremely painful for at least two weeks.
The mechanism by which negative energy makes copper conductors
cold but will also heat light bulb filaments is not understood.
Tom Bearden has coined the term "Gravito Stiction" for this
process and has described how he believes it works.
On the human side of the VTA development, some incidents are
worth telling. Two people from Australia, who claimed they wanted
to help Floyd, stole his note book and promptly asked John Bedini
for help in replicating the VTA based on the notebook contents.
John recognized the notebook as belonging to Floyd and promptly
asked them to leave. However, the notebook was never recovered.
Floyd has received many death threats over the phone, and some
threats face to face. A well dressed gentleman in a expensive
suit, tie, hat, and hundred dollar shoes approached Floyd on the
sidewalk of the street where he lives and introduced himself as
Cecil Brown. He showed him a picture of Floyd inside his apart-
ment. Cecil then told him that he represented a conglomerate that
did not want Floyd's device to appear in the world at this time.
He further stated that sometimes unfortunate things happen to
people who do not comply with the wishes of others. He then
retrieved the picture and departed. Incidences like this do
impart significant concern in Floyd's mind!
One real unsung hero of the human side of this story is Al
Margolin, who for many years has provided test equipment, fabri-
cation help, and transportation for Floyd and Rose whenever
needed, and it was needed many times.
Floyd's long time friend and former employer Bill Lawry has
provided living and project expenses and fabrication help when
The reliable conditioning of the magnets in a manner that
assures long time operation is the Achilles heel of this device.
With the help of enough of the right people this device may
change our world and open a new field of physics! This adventure
of course is an on going and the final goal of powering the world
with the VTA is still a long ways off.
