Although the CAD drawings provided with your membership are for information purposes only, they are the most complete and accurate known to date and have been used to construct highly efficient rotary engines. Photographic documentation of engines built by TEBA members is also provided. The power and simplicity of this engine is truly amazing! This is the only high power turbine that can actually be built inexpensively using only simple machining tools that can be found in many basements and garages, yet have operational advantages over multi-million dollar machines. Bladed turbines having similar performance specifications would be completely out of the question for an average individual to build much less afford. Not so with Tesla’s “bladeless” device.
The drawings you will receive with membership faithfully detail the essential elements incorporated into Tesla’s original 110 HP design with the exception of the nozzle. Tesla’s later variable nozzle design, originally intended for his vertical take off aircraft, is substituted. Tesla’s later nozzle design allows for maximum efficiency, even at low power settings, without having to replace a fixed nozzle insert, as called for in Tesla’s earlier experimental prototype. This nozzle has proven to perform exactly as Tesla claimed in units that have recently been built. It is particularly attractive for applications with variable steam outputs as occur with solar heated systems. This nozzle can be tuned during operation, dynamically, for maximum steam velocity and therefore maximum efficiency.
The engine drawings, while complete for a single stage steam application, also represent the same basic design described by Tesla for use in the hot section of his petroleum fueled version of the engine.
As part of your membership you also receive a periodic newsletter
updating the latest news reported from the field and availability

Tesla’s Engine is included with membership when you Join TEBA
From the New York Herald Tribune Oct. 15, 1911
It does not take a mechanical expert to imagine the limitless
possibilities of such an engine. It takes very little effort to
conjure up a picture of a new world of industry and
transportation made possible by the invention of such a device.
“Revolutionary” seems a mild term to apply to it. That, however,
is the word the inventor uses in describing it—Nikola Tesla, the
scientist whose electrical discoveries underlie all modern
electrical power development, whose experiments and deductions
made the wireless telegraph possible, and who now, in the
mechanical field, has achieved a triumph even more far reaching
than anything he accomplished in electricity.
There is something of the romantic in this discovery of the
famous explorer of the hidden realms of knowledge. The pursuit
of an ideal is always romantic, and it was in the pursuit of an
ideal which he has been seeking twenty years that Dr. Tesla made
his great discovery. That ideal is the power to fly—to fly with
certainty and absolute safety—not merely to go up in an
aeroplane and take chances on weather conditions, “holes in the
air,” tornadoes, lightning and the thousand other perils the
aviator of today faces, but to fly with the speed and certainty
of a cannon ball, with power to overcome any of nature’s aerial
forces, to start when one pleases, go whither one pleases and
alight where one pleases. That has been the aim of Dr. Tesla’s
life for nearly a quarter of a century. He believes that with
the discovery of the principle of his new motor he has solved
this problem and that incidentally he has laid the foundations
for the most startling new achievements in other mechanical
lines.
The change came about when young Tesla
showed the way by which the power of Niagara Falls could be
utilized. The right to divert a portion of the waters of Niagara
had been granted; then arose the question of how best to utilize
the tremendous power thus made available—how to transmit it to
the points where it could be commercially utilized. An
international commission sat in London and listened to theories
and practical plans for months.
Up to that time the only means of utilizing electric power was
the direct current motor, and direct current dynamos big enough
to be of practical utility for such a gigantic power development
were not feasible.
Then came the announcement of young Tesla’s discovery of the
principle of the alternating current motor. Practical tests
showed that it could be built—that it would work.
That discovery, at that opportune time, decided the
commission. Electricity was determined upon as the means for the
transmission of Niagara’s power to industry and commerce. Today
a million horse power is developed on the brink of the great
cataract, turning the wheels of Buffalo, Rochester, Syracuse and
the intervening cities and villages operating close at hand the
great new electro-chemical industries that the existence of this
immense source of power has made possible, while all around the
world a thousand waterfalls are working in the service of
mankind, sending the power of their “white coal” into remote and
almost inaccessible corners of the globe, all because of Nikola
Tesla’s first great epoch making discovery.
“It is the greatest invention in a century,” wrote one of the
foremost American engineers, a man whose name stands close to the
top of the list of those who have achieved scientific fame and
greatness.
“No invention of such importance in the automobile trade has
yet been made,” declared the editor of one of the leading
engineering publications. Experts in other engineering lines
pointed out other applications of the new principle and letters
asking for further information poured in on Dr. Tesla from the
four quarters of the globe.
“Oh, I've had too much publicity,” he said, when I telephoned
to him to ask for an interview in order to explain his new
discovery to the non-technical public. It took a good deal of
persuasion before he reluctantly fixed an hour when he would see
me, and a good bit more after that before he talked at all
freely. When he did speak, however, he opened up vistas of
possible applications of the new engine that staggered the
imagination of the interviewer.
Looking out over the city from the windows of his office, on the
twentieth floor of the Metropolitan Tower, his face lit up as he
told of his life dream and its approaching realization, and the
listener’s fancy could almost see the air full of strange flying
craft, while huge steamships propelled at unheard of speeds
ploughed the waters of the North River, automobiles climbed the
very face of the Palisades, locomotives of incredible power
whisked wheeled palaces many miles a minute and all the
discomforts of summer heat vanished as marvelous refrigerating
plants reduced the temperature of the whole city to a comfortable
maximum—for these were only a few of the suggestions of the
limitless possibilities of the latest Tesla discovery.
“Just what is your new invention?” I asked.
“I have accomplished what mechanical engineers have been
dreaming about ever since the invention of steam power,” replied
Dr. Tesla. “That is the perfect rotary engine. It happens that
I have also produced an engine which will give at least
twenty-five times as much power to a pound of weight as the
lightest weight engine of any kind that has yet been produced.
“In doing this I have made use of two properties which have
always been known to be possessed by all fluids, but which have
not heretofore been utilized. These properties are adhesion and
viscosity.
“Put a drop of water on a metal plate. The drop will roll
off, but a certain amount of the water will remain on the plate
until it evaporates or is removed by some absorptive means. The
metal does not absorb any of the water, but the water adheres to
it.
“The drop of water may change its shape, but until its
particles are separated by some external power it remains intact.
This tendency of all fluids to resist molecular separation is
viscosity. It is especially noticeable in the heavier oils.
“It is these properties of adhesion and viscosity that cause
the “skin friction” that impedes a ship in its progress through
the water or an aeroplane in going through the air. All fluids
have these qualities—and you must keep in mind that air is a
fluid, all gases are fluids, steam is fluid. Every known means
of transmitting or developing mechanical power is through a
fluid medium.
“Now, suppose we make this metal plate that I have spoken of
circular in shape and mount it at its centre on a shaft so that
it can be revolved. Apply power to rotate the shaft and what
happens? Why, whatever fluid the disk happens to be revolving in
is agitated and dragged along in the direction of rotation,
because the fluid tends to adhere to the disk and the viscosity
causes the motion given to the adhering particles of the fluid to
be transmitted to the whole mass. Here, I can show you better
than tell you.”
Dr. Tesla led the way into an adjoining room. On a desk was a
small electric motor and mounted on the shaft were half a dozen
flat disks, separated by perhaps a sixteenth of an inch from one
another, each disk being less than that in thickness. He turned
a switch and the motor began to buzz. A wave of cool air was
immediately felt.
“There we have a disk, or rather a series of disks, revolving
in a fluid—the air,” said the inventor. “You need no proof to
tell you that the air is being agitated and propelled violently.
If you will hold your hand over the centre of these disks—you
see the centres have been cut away—you will feel the suction as
air is drawn in to be expelled from the peripheries of the disks.
“Now, suppose these revolving disks were enclosed in an air
tight case, so constructed that the air could enter only at one
point and be expelled only at another—what would we have?"
“You'd have an air pump,” I suggested.
“Exactly--an air pump or blower,” said Dr. Tesla.
“There is one now in operation delivering ten thousand cubic
feet of air a minute. “Now, come over here.”
He stepped across the hall and into another room, where three
or four draughtsmen were at work and various mechanical and
electrical contrivances were scattered about. At one side of the
room was what appeared to be a zinc or aluminum tank, divided
into two sections, one above the other, while a pipe that ran
along the wall above the upper division of the tank was connected
with a little aluminum case about the size and shape of a small
alarm clock. A tiny electric motor was attached to a shaft that
protruded from one side of the aluminum case. The lower division
of the tank was filled with water.
“Inside of this aluminum case are several disks mounted on a
shaft and immersed in a fluid, water,” said Dr. Tesla. “From
this lower tank the water has free access to the case enclosing
the disks. This pipe leads from the periphery of the case. I
turn the current on, the motor turns the disks and as I open this
valve in the pipe the water flows.”
He turned the valve and the water certainly did flow.
Instantly a stream that would have filled a barrel in a very few
minutes began to run out of the pipe into the upper part of the
tank and thence into the lower tank.
“This is only a toy,” said Dr. Tesla. “There are only half a
dozen disks— ‘runners,’ I call them—each less than three inches
in diameter, inside of that case. They are just like the disks
you saw on the first motor—no vanes, blades or attachments of
any kind. Just perfectly smooth, flat disks revolving in their
own planes and pumping water because of the viscosity and
adhesion of the fluid. One such pump now in operation, with
eight disks, eighteen inches in diameter, pumps four thousand
gallons a minute to a height of 360 feet.”
We went back into the big, well lighted office. I was
beginning to grasp the new Tesla principle.
“Suppose now we reversed the operation,” continued the
inventor. “You have seen the disks acting as a pump. Suppose we
had water, or air under pressure, or steam under pressure, or gas
under pressure, and let it run into the case in which the disks
are contained—what would happen?"
“The disks would revolve and any machinery attached to the
shaft would be operated—you would convert the pump into an
engine,” I suggested.
“That is exactly what would happen—what does happen,” replied
Dr. Tesla. “It is an engine that does all that engineers have
ever dreamed of an engine doing, and more. Down at the Waterside
power station of the New York Edison Company, through their
courtesy, I have had a number of such engines in operation. In
one of them the disks are only nine inches in diameter and the
whole working part is two inches thick. With steam as the
propulsive fluid it develops 110-horse power, and could do twice
as much.”
“You have got what Professor Langley was trying to evolve for
his flying machine—an engine that will give a horse power for a
pound of weight,” I suggested.
“I have got more than that,” replied Dr. Tesla. “I have an
engine that will give ten horse power to the pound of weight.
That is twenty-five times as powerful as the lightest weight
engine in use today. The lightest gas engine used on aeroplanes
weighs two and one-half pounds to the horse power. With two and
one-half pounds of weight I can develop twenty-five horse power.”
“That means the solution of the problem of flying,” I
suggested.
“Yes, and many more,” was the reply. “The applications of
this principle, both for imparting power to fluids, as in pumps,
and for deriving power from fluids, as in turbine, are boundless.
It costs almost nothing to make, there is nothing about it to
get out of order, it is reversible—simply have two ports for the
gas or steam, to enter by, one on each side, and let it into one
side or other. There are no blades or vanes to get out of
order—the steam turbine is a delicate thing.”
I remembered the bushels of broken blades that were gathered
out of the turbine casings of the first turbine equipped
steamship to cross the ocean, and realized the importance of this
phase of the new engine.
“Then, too,” Dr. Tesla went on, “there are no delicate
adjustments to be made. The distance between the disks is not a
matter of microscopic accuracy and there is no necessity for
minute clearances between the disks and the case. All one needs
is some disks mounted on a shaft, spaced a little distance apart
and cased so that a fluid can enter at one point and go out at
another. If the fluid enters at the centre and goes out at the
periphery it is a pump. If it enters at the periphery and goes
out at the center it is a motor.
“Coupling these engines in series, one can do away with
gearing in machinery. Factories can be equipped without
shafting. The motor is especially adapted to automobiles, for it
will run on gas explosions as well as on steam. The gas or steam
can be let into a dozen ports all around the rim of the case if
desired. It is possible to run it as a gas engine with a
continuous flow of gas, gasoline and air being mixed and the
continuous combustion causing expansion and pressure to operate
the motor. The expansive power of steam, as well as its
propulsive power, can be utilized as in a turbine or a
reciprocating engine. By permitting the propelling fluid to move
along the lines of least resistance a considerably larger
proportion of the available power is utilized.
“As an air compressor it is highly efficient. There is a
large engine of this type now in practical operation as an air
compressor and giving remarkable service. Refrigeration on a
scale hitherto never attempted will be practical, through the use
of this engine in compressing air, and the manufacture of liquid
air commercially is now entirely feasible.
“With a thousand horse power engine, weighing only one hundred
pounds, imagine the possibilities in automobiles, locomotives and
steamships. In the space now occupied by the engines of the
Lusitania twenty-five times her 80,000 horse power could be
developed, were it possible to provide boiler capacity sufficient
to furnish the necessary steam.”
“And it makes the aeroplane practical,” I suggested.
“Not the aeroplane, the flying machine,” responded Dr. Tesla.
“Now you have struck the point in which I am most deeply
interested—the object toward which I have been devoting my
energies for more than twenty years—the dream of my life. It
was in seeking the means of making the perfect flying machine
that I developed this engine.
“Twenty years ago I believed that I would be the first man to
fly; that I was on the track of accomplishing what no one else
was anywhere near reaching. I was working entirely in
electricity then and did not realize that the gasoline engine was
approaching a perfection that was going to make the aeroplane
feasible. There is nothing new about the aeroplane but its
engine, you know.
“What I was working on twenty years ago was the wireless
transmission of electric power. My idea was a flying machine
propelled by an electric motor, with power supplied from stations
on the earth. I have not accomplished this as yet, but am
confident that I will in time.
“When I found that I had been anticipated as to the flying
machine, by men working in a different field, I began to study the
problem from other angles, to regard it as a mechanical rather
than an electrical problem. I felt certain there must be some
means of obtaining power that was better than any now in use. And
by vigorous use of my gray matter for a number of years, I grasped
the possibilities of the principle of the viscosity and adhesion
of fluids and conceived the mechanism of my engine. Now that I
have it, my next step will be the perfect flying machine.”
“An aeroplane driven by your engine?” I asked.
“Not at all,” said Dr. Tesla. “The aeroplane is fatally
defective. It is merely a toy—a sporting play-thing. It can
never become commercially practical. It has fatal defects. One
is the fact that when it encounters a downward current of air it
is helpless. The “hole in the air” of which aviators speak is
simply a downward current, and unless the aeroplane is high
enough above the earth to move laterally but can do nothing but
fall.
“There is no way of detecting these downward currents, no way
of avoiding them, and therefore the aeroplane must always be
subject to chance and its operator to the risk of fatal accident.
Sportsmen will always take these chances, but as a business
proposition the risk is too great.
“The flying machine of the future—my flying machine—will be
heavier than air, but it will not be an aeroplane. It will have
no wings. It will be substantial, solid, stable. You cannot
have a stable airplane. The gyroscope can never be successfully
applied to the airplane, for it would give a stability that
would result in the machine being torn to pieces by the wind,
just as the unprotected aeroplane on the ground is torn to pieces
by a high wind.
“My flying machine will have neither wings nor propellers.
You might see it on the ground and you would never guess that it
was a flying machine. Yet it will be able to move at will
through the air in any direction with perfect safety, higher
speeds than have yet been reached, regardless of weather and
oblivious of “holes in the air” or downward currents. It will
ascend in such currents if desired. It can remain absolutely
stationary in the air, even in a wind, for great length of time.
Its lifting power will not depend upon any such delicate devices
as the bird has to employ, but upon positive mechanical action.”
“You will get stability through gyroscopes?” I asked.
“Through gyroscopic action of my engine, assisted by some
devices I am not yet prepared to talk about,” he replied.
“Powerful air currents that may be deflected at will, if
produced by engines and compressors sufficiently light and
powerful, might lift a heavy body off the ground and propel it
through the air,” I ventured, wondering if I had grasped the
inventor’s secret.
Dr. Tesla smiled an inscrutable smile.
“All I have to say on that point is that my airship will have
neither gas bag, wings nor propellers,” he said. “It is the
child of my dreams, the product of years of intense and painful
toil and research. I am not going to talk about it any further.
But whatever my airship may be, here at least is an engine that
will do things that no other engine ever has done, and that is
something tangible.”

Of all the endless variety of phenomena which nature presents to
our senses, there is none that fills our minds with greater
wonder than that inconceivably complex movement which, in its
entirety, we designate as human life. Its mysterious origin is
veiled in the forever impenetrable mist of the past, its
character is rendered incomprehensible by its infinite intricacy,
and its destination is hidden in the unfathomable depths of the
future. Whence does it come? What is it? Whither does it tend?
are the great questions which the sages of all times have
endeavored to answer.
Modern science says: The sun is the past, the earth is the
present, the moon is the future. From an incandescent mass we
have originated, and into frozen mass we shall turn. Merciless
is the law of nature, and rapidly and irresistibly we are drawn
to our doom. Lord Kelvin, in his profound meditations, allows us
only a short span of life, something like six million years,
after which time the sun’s bright light will have ceased to
shine, and its life-giving heat will be a lump of ice, hurrying
on through the eternal night. But so not let us despair. There
will still be left on it a glimmering spark of life, and there
will be a chance to kindle a new fire on some distant star. This
wonderful possibility seems, indeed, to exist, judging from
Professor Dewar’s beautiful experiments with liquid air, which
show that germs of organic life are not destroyed by cold, no
matter how intense; consequently they may be transmitted through
the interstellar space. Meanwhile the cheering lights of science
and art, ever increasing in intensity, illuminate our path, and
the marvels they disclose, and the enjoyments they offer, make us
measurably forgetful of the gloomy future.
Though we may never be able to comprehend human life, we know
certainly that it is movement, of whatever nature it be. The
existence of a movement unavoidably implies a body which is being
moved and a force which is moving it. Hence, wherever there is
life, there is a mass moved by a force. All mass possesses
inertia, all force tends to persist. Owing to this universal
property and condition, a body, be it at rest or in motion, tends
to remain in the same state, and a force, manifesting anywhere
and through whatever cause, produces an equivalent opposing
force, and as an absolute necessity of this it follows that every
movement in nature must be rhythmical. Long ago this simple
truth was clearly pointed out by Herbert Spencer, who arrived at
it through a somewhat different process of reasoning. It is
borne out in everything we perceive—in the movement of a planet,
in the surging and ebbing of the tide, in the
reverberations of the air, the swinging of a pendulum, the
oscillations of an electric current,
and in the infinitely varied phenomena of organic life. Does not
the whole of human life attest it? Birth, growth, old age, and
death of an individual, family, race, or nation, what is it all
but a rhythm? All life-manifestation, then, even in its most
intricate form, as exemplified in man, however involved and
inscrutable, is only a movement, to which the general laws of
movement which govern throughout the physical universe must be
applicable.
When we speak of man, we have a conception of humanity as a
whole, and before applying scientific method to the investigation
of his movement, we must accept this as a physical fact. But can
any one doubt today that millions of individuals and all the
innumerable types and charters constitute an entity, a unit?
Though free to think and act, we are held together, like the
stars in the firmament, with ties inseparable. These ties we
cannot see, but we can feel them. I cut myself in the finger,
and it pains me: this finger is a part of me. I see a friend
hurt, and it hurts me, too: my friend and I are one. And now I
see stricken down an enemy, a lump of matter which, of all the
lumps of matter in the universe, I care least for, and still it
grieves me. Does this not prove that each of us is only a part
of a whole?
For ages this idea has been proclaimed in the consummately wise
teachings of religion, probably not alone as a means of insuring
peace and harmony among men, but as a deeply founded truth. The
Buddhist expresses it in one way, the Christian in another, but
both say the same: We are all one. Metaphysical proofs are,
however, not the ones which we are able to bring forth in support
of this idea. Science, too, recognizes this connectedness of
separate individuals, though not quite in the same sense as it
admits that the suns, planets, and moons of a constellation are
one body, and there can be no doubt that it will be
experimentally confirmed in times to come, when our means and
methods for investigating psychical and other states and
phenomena shall have been brought to great perfection. Still
more: this one human being lives on and on. The individual is
ephemeral, races and nations come and pass away, but man remains.
Therein lies the profound difference between the individual and
the whole. Therein, too, is to be found the partial explanation
of many of those marvelous phenomena of heredity which are the
results of countless centuries of feeble but persistent
influence.
Conceive, then , man as a mass urged on by a force. Though this
movement is not of a translatory character, implying change of
place, yet the general laws of mechanical movement are applicable
to it, and the energy associated with this mass can be measured,
in accordance with well-known principles, by half the product of
the mass with the square of a certain velocity. So, for
instance, a cannon-ball which is at rest possesses a certain
amount of energy in the form of heat, which we measure in a
similar way. We imagine the ball to consist of innumerable
minute particles, called atoms or molecules, which vibrate or
whirl around one another. We determine their masses and
velocities, and from them the energy of each of these minute
systems, and adding them all together, we get an idea of the
total heat-energy contained in the ball, which is only seemingly
at rest. In this purely theoretical estimate, this energy may
then be calculated by multiplying half of the total mass—that is,
half of the sum of all the small masses—with the square of a
velocity which is determined from the velocities of the separate
particles. In like manner we may conceive of human energy being
measured by half the human mass multiplied with the square of a
velocity which we are not yet able to compute. But our
deficiency in this knowledge will not vitiate the truth of the
deductions I shall draw which rest on the firm basis that the
same laws of mass and force govern throughout nature.
Man, however, is not an ordinary mass, consisting of spinning
atoms and molecules, and containing merely heat-energy. He is a
mass possessed of certain higher qualities by reason of the
creative principle of life with which he is endowed. His mass,
as the water in and ocean wave, is being continuously exchanged,
new taking the place of the old. Not only this, but he grows,
propagates, and dies, thus altering his mass independently, both
in bulk and density. What is most wonderful of all, he is
capable of increasing or diminishing his velocity of movement by
the mysterious power he possesses of appropriating more or less
energy from other substance, and turning it into motive energy.
But in any given moment we may ignore these slow changes and
assume that human energy is measured by half the product of man’s
mass with the square of a certain hypothetical velocity. However
we may compute this velocity, and whatever we may take the
standard of its measure, we must, in harmony with this
conception, come to the conclusion that the great problem of
science is, and always will be, to increase the energy thus
defined. Many years ago, stimulated by the perusal of that
deeply interesting work, Draper’s “History of the Intellectual
Development of Europe,” depicting so vividly human movement, I
recognized that to solve this eternal problem must ever be the
chief task of the man of science. Some results of my own efforts
to this end I shall endeavor briefly to describe here.

Introduction
Tesla’s New Monarch of Machines
There was a time when men of science were skeptical—a time
when they ridiculed the announcement of revolutionary
discoveries. Those were the days when Nikola Tesla, the young
scientist from the Balkans, was laughed at when he urged his
theories on the engineering world. Times have changed since
then, and the “practical” engineer is not so incredulous about
“scientific” discoveries.
Today the engineering world listens respectfully when Dr.
Tesla speaks. The first announcement of the discovery of his new
mechanical principle was made in a technical periodical in
mid-September, 1911. Immediately it became the principal topic
of discussions wherever engineers met.
