While on the subject of turbine size, I know that the direction you're
taking is toward 18" disc turbines to reduce shaft speed. But of those
who took the opposite route, what were the smallest, most compact working
bladeless turbines on record? To what applications were these put?

Just how small is small? Would the 12" turbine be considered a 'small unit'?
I wanted an overview of the varieties of bladeless engines Tesla himself
investigated. Which is why I also asked about the number of discs he stacked
for this particular model to output the 100 HP that was recorded.

Yes, I heard about this wonder from Mr. Hannon in an early posting. But this
would be the record for pumps. Were similar-sized turbines ever built?

Meaning the central spokes/exhaust holes as illustrated in Tesla's "Fluid
Propulsion" patent # 1,061,142 were not followed.

Forgot to mention that this pump was operating at 140,000 rpm.
We are not aware of any additional information about these early
units besides that recorded by O'Neil.
We do have documentation on his 9 3/4" which had .03" disc thickness
and spacing. The Eighteen inch version used .06" disc thickness
and .06 disc spacing.
TEBA member Advanced Dynamics built an 11" version using .03 discs
and spacing that performed well. Beyond this, wider spacing is
advisable as the back pressures become much more significant. Those
that built the 11" versions disregarded Tesla's example and
used .03" in an 18" version. This resulted in a warped rotor.
Tesla knew of what he spoke.
To answer an earlier question in this thread, about using Tesla's device
as a gas turbine. Yes it can and has been done, contrary to the rattlings
of an uninformed critic. He is indeed correct, however, that billions of
dollars have been spent to make bladed turbines work efficiently.
In contrast almost nothing has been invested in developing the Tesla turbine.
The potential for further development is therefore immense.
Recently Tesla received headline coverage in the
Seattle Post - Intelligencer. Oct. 16 1996. Page 1 headline:
"From an obscure genius comes a tiny pump for computer age"
The University of Washington has "rediscovered" a component of
the Tesla gas turbine, namely the "Valvular Conduit" which
we have been promoting since 1990. (They do not refer to
it properly throughout the article, calling it a Tesla pump.)
Tesla used the valvular conduit to allow his turbine to operate
without a conventional compressor stage.
In a conventional gas turbine approximately 2/3rds of the power
produced by the turbine is consumed by the compressor. Only 1/3
of the total power is therefore remaining for shaft output.
Page 38 of "Tesla's Engine - A New Dimension For Power" contains
a cross sectional view of a "compressorless" gas turbine employing
valvular conduits.
A TEBA member built and commercially tested the valvular conduit
long before the University of Washington got wind of it. The
experts that tested the device were dumfounded, as it contains
absolutely no moving parts and can not be breached like all the
other devices with which they were familiar.
Fred Forster, professor of mechanical engineering, is quoted in the
headline story, regards Tesla:
"It's easy for an engineering or science student to
think that the last 10 years are all that matters."
Indeed!
This article will be reproduced in the next issue of TEBA NEWS.
Look back, 85 years, almost to the day of the recent headline:
New York Herald Tribune; Page 1, Oct. 15 1911:
"WILL TESLA'S NEW MONARCH OF MACHINES REVOLUTIONIZE THE WORLD?"
"Noted Balkan Scientist claims to have perfected an engine that
will develop ten horsepower to every pound of weight, and promises
soon to give to the world a flying machine without wings, propeller,
or gas bag. Characterizes aeroplanes of today as mere dangerous
toys compared with the safe and stable appliance which will be
used in a short time to dash through the air at a speed now
unimagined....
"That has been the aim of Dr. Tesla's life for nearly a quarter
of a century. He believes that with the discovery of his new motor
he has solved the problem and that incidentally he has laid the
foundations for the most startling new achievements in other
mechanical lines.
"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...."
>>The smallest unit we have documentation for is a 1" runner diameter,
>>three stage pump built by Aerojet. It delivered liquid hydrogen
>>to a head rise of 24,000 Feet @ 15 Gallons Per Minute.
>Yes, I heard about this wonder from Mr. Hannon in an early posting. But this

No, only small toys. Advanced Dynamics did build a small 5"
version with attached generator. It runs up to about 40,000 rpm
unloaded with 80psi compressed air. It brightly illuminates an
incandescent bulb at about 35k rpm. This is a fun project that
almost anyone could build. It is featured in our Spring 95 newsletter.
How much of an informed critic? Try building one to Tesla's spec's, say
the 10" model. The materials (bottom end) costs will be a few hundred
bucks, and you'll end up with a 55-lb, 110 hp engine turning about 15,000
rpm. I've got a smaller one (sloppily built, with poor balance) turning
well over 50,000 rpm. The first time I ran it, it scared the hell out of
me, because it wouldn't quit accelerating, and I shut it down finally out
of fear that it would just keep gaining rpm until it self-destructed.
Take my word for it - the Tesla turbine works so well, and if the world
knew, piston engines and pumps would have been obsolete a long, long time
ago. In fact, it is so simple to build, and so effective, that each new
effort I make with it is repeatedly boggling my mind.

Surely, if you build a low-cost high-efficiency device, you will
revolutionize industry and transport, and make a ton of money.
I would not assume, however, that because there is an element of
obscurity and an 'apparent' lack of R&D, the device has modern
and demanding application.
The solutions are many but the applications are few due to the
even *more* demanding market drive for cost-effectiveness in
production and other high-tech considerations such as weight.
NASA (or contractor) is reengineering shuttle engines to achieve
a 1.5% increase in thrust at tremendous cost, pursuing that fine
edge of ultimate conversion of fuel to thrust. So yes, there is
a market even for such small increases for NASA and much larger
increases sought for aircraft and tanks.
The market awaits whatever FIRSTLY cost-effective device
advancements for mass production and SECONDLY efficiency-effective
advancements for niche products.
So you have two avenues here to pursue. Good engineers and
scientists can predict very closely the kinds of results
expected in *mechanical* devices, so it won't be too hard
to whip up an expectation of value in both the cost-effective
market and the efficiency-effective one.
Do a small group of you have some insight into a truly "forgotten"
technology? Perhaps. Tesla certainly pioneered a great many
things and I respect his contributions as I do Edison, Bell and
others. The world *has* taken up as much as the technology can
deliver to the market and shelved what it can't (with exception
of the odd home-enthusiast).
The closest to a recently re-used old and "forgotten" technology
was the bonding of a ceramic and a metal with a material that
can take the expansion and contraction of both, for satellite
use. It turned out that the old formula had been published
but was out of use, and the only source for that formula was
found in a priest's private library of books picked up when
the Russians dicarded all the contents of their libraries
a decade back. (the formula applied to very specific materials)
Tesla's radiated energy idea is an example of a possible method
of power distribution that is impracticable and will never be used.
Even the emininently possible microwave solution has problems
and orders of magnitude that make it impracticable.
We'll see. If the turbine has merits to suit market needs,
someone will adapt it, and soon. With coming rush for low
-emission vehicles and higher-powered mass transport, someone
will make a lot of money *IF* it's so good.
S.
I'm really fascinated by the naivete' of some people who even seem to be
operating in the "upper circles" of technology. Tesla invented radio, but
if it weren't for a severe battle in court, Marconi would still be
considered the inventor, despite the fact that he literally stole the
technology from Tesla. I would suppose that this person also believes
that Preston Tucker really was a "shyster," and that the "Tin Goose" was
not "up to snuff" to make it in the "progressive automobile market" we
have in this country, despite its pop-out windshield, padded dash, seat
belts, and numerous other items which no other car on the market had, or
would have for years. I personally knew of an inventor in Sebastopol, CA,
(I was dating his secretary, who couldn't stop talking about her
boss's new technology) who had a working vehicle and a market, only to
discover that his suppliers suddenly disappeared, and then two
consecutive "accidental" fires in his shop and offices, which drove him
out of business.
Ask yourself this - why is it that one of, if not the, the most
prolific inventors in the history of mankind, the father of alternating
current, builder and designer of the original hydroelectric facility at
Niagra Falls, inventor of the AC motor, of robotics, radio, radio
control, present day state-of-the-art radar-powered aircraft (no
practicable use for his transmitted power, huh), scalar wave technology
(HAARP), and a myriad of other devices successful in today's world, died
alone, emaciated, and poor in a hotel room in NYC? Was it because his
inventions couldn't "cut the mustard in the real world?" Or was it that
the same type of people who ruined Tucker did it to Mr. Tesla even before
him? You can bet that every attempt outside of the ruthless international
corporations will be met one way or another by them. That is what they
do, and no amount of "naive" banter about "only the good stuff succeeds
on its own merits" will ever mask that truth. I suggest anyone who doubts
this read "When Corporations Rule the World" by David Korten, former
Harvard professor, and world-renowned student of the impact of those
corporations on the future of us all.
I ask a simple question - why, in 1910, would a 55-lb, 110 hp engine
the size of a small paint bucket, with ONE moving part, built far easier
and much less costly than a much more complex, less reliable, much
noiser, far less efficient piston engine of the era with 30 hp weighing
many times that simple engine?

Skip the Tesla turbine, the future is in monopoles! My magnetic monopole, jointly
developed with one of Bill Gates' best men - you know Gates, Microsoft? This thing
can repulse 50 tons and it only weighs 45 lbs. Power is supplied by gas, electric,
or even Minute Rice! For more info, send $29.95 to S.C.A.M. (Secret Canadian Association
for Monopoles), PO Box 1945, Nest Egg, CA.
Please do not request specifics as to power output, input, or anything else, as I do
not have time to respond to doubters.

There are *lots* of nuclear reactors in space, or at least spent reactors. Of course, it may
be a stretch to relate them to the type of reactor most people think of. Instead of using the
heat generated by the reaction to heat some liquid medium, which drives a turbine, which turns
a generator, the heat is turned directly into electricity using thermopyles. These are like the
ones in your hot water heater, but there are many of them, and the government can afford certain
exotic metals to get the greatest efficiency. Anyhoo, I am not sure if they actually have a
fission reaction in these small space reactors, or if it is just heat generated by element decay
(half life and all that). I think several of these reactors were placed on the moon to power
certain research studies, the Voyager series had em, and possibly the Viking series too. And wasn't
there a big stink by the enviro's about the Galileo because it had one?

These things cost too much to implement for the cost-effective market,
which is why people like their Volvos and BMWs and which is also why I
drive a General Motors bomb.
Tell me why a 300 passenger jet doesn't carry parachutes?

While I don't subscribe to conspiracy theories, I do believe there
are a few greedy and powerful people out their who want to protect
their own interests. They're called criminals. But in the Tesla
case at hand - the disc turbine - there isn't just one popular
design, there are hundreds of various pumping and power conversion
devices, and it is a very specific market.

Do tell about the radar powere aircraft. This sounds a little
urban-mythy to me, especially when you say *radar* powered as
if *radar* were some new kind of energy frequency!

Not from a conspiracy. You seem very willing to accept that there is
some kind of overwhelming push for expensive mediocrity instead of
well-priced excellence. If this were so, we'd all be putting around
in propellor planes, the largest taking 50 passengers, and cars
that just gulped fuel "because its in the interest of the oil
companies." Why, have you seen a carburetor that can be modified
to double the mileage, or an engine design that can achieve
100% energy conversion?
Maybe, just maybe, you are missing out on the kind of factual
information on physics and limits of application to allow
yourself to dream a little too much.

I'm sure he got shafted - hell, I've been shafted a number of times,
which is why I'm still poor as hell. And if you don't get on with
the business of developing this *great* device, you will get shafted
too - if indeed it is such an effective unit.

Don't assume that one and ONLY one person can dream up a design
or application, especially over several decades. Technology
provides a hotbed of development that bring into it tens of
thousands of engineers and scientists all looking for similar
solutions and advantages for their employers.
Secrecy? I still marvel how the US built the Atomic bomb.
They built a uranium manufacturing centre that used 200,000
cascade tanks, each tank as large as your living room.
Do you know how much material and space that required?

This is just talk. Pure talk. You have no figures to even start
making this claim look real. I *know* that this device could be built
to 1990's standards with ceramics, ultrahard bearings, a rash of
lubricants and seals to satisfy temperatures in the thousands of
degrees C range, metals and alloys with wonderous qualities.
OK, you and a dozen others have been entertaining yourselves
with this Tesla obsession. So build it or "science project" it.
Let's see some figures on model, like RPM, Torque, fuel types, fuel
consumption, wear data, lube systems, cooling systems, running temps
etc.
Try discussing, for example, a fuel injection system for this
beast. Try thinking where the hot spots will be and how it
will be cooled.
You haven't even got up to date MODERN drawings!
55lb and 110 horsepower means nothing because it is isolated
from the kind of science and engineering reality that is
expressed in a larger range of data and graphs.
I was particularly amused at another poster who told of
his model that hit 50,000rpm and wasn't very well balanced!
I wouldn't want to be in the same room with that!
I recently expressed my doubts that a Nuclear-Powered
aircraft was attempted in the 1960's because of weight
vs output. I was assured that it had been done, but
was only flown once and canned. *A* reason given was
that it was unsafe for a number of reasons, but that
never really stopped the Gov't.
The bottom line is, do something and do it soon, or I'll
be reading in 30 years time that a new generation has
discovered some amazing and suppressed technology. Hell,
this is a simple turbine device, for gods sakes! It and
"rocket science" aren't even closely related!
S.
Because the turbine is only half the engine. The generation and
regeneration of the steam takes up many times more room. Take a look as
the relative size of the boiler and the pistons on a steam locomotive!
And take a look at history. The Stanley Steamer was a very successful
car that had the early technological lead, but they couldn't lick the
boiler problems with the technology at hand.
Tesla was indeed a genius, but not everything he did turned to gold. He
was very much a visual thinking, not a theoretician. This led him to
invent the AC motor, but at the same time led him to some misconceptions
about the nature of electricity.
He was also completely ignorant of the realities of economics, which led
him to spend fortunes of other people's money on projects that never
produced any practical outcomes, and to sign away his one really
profitible patent for peanuts.
--mike
Have you ever considered that maybe they really aren't that naive? Maybe they have access
to equipment that you don't, that they have tried to measure the efficiency of some things
that are highly touted in old literature, and find that the they really are not all they
are cracked up to be?
How much effort have you made to really measure the efficiency of turbines. And in any
steam system, the "motor" is only part of the efficiency equation.
I cannot believe there is any conspiracy against the Tesla turbines. I know a lot of very
sharp MEs. These guys are not dumb. They claim the efficiency of the Tesla turbine is not
what some works claim.

Ahhh, I knew that the conspiracy theory of history had to show up here
sometime soon.
Michael, you are certainly correct in that people don't always get
credit for their ideas, Tesla is unfortunately a prime example. BUT, you
missed what I think of as a major point in Phillip's letter. If this
turbine is so much better than what we have today, why isn't it being
used?? Why hasn't someone stolen the idea and made a ton of money with
it? There must be a reason for this, and conspiracy theories don't wash
here. Truly effective IDEAS are really tough to suppress when they are
as fundamental and publicly available as turbine or motor technology.
INDIVIDUALS are much easier to suppress, granting that your portrayal of
Tucker is correct.

You've got to be kidding - Tesla had all of the math and design to back
up each of his inventions, and did, in fact build a gasoline version of
his turbine (actually, it was a multi-fuel engine), so the steam theory
of th turbine is out as well (it actually used much less steam as a steam
engine than any other type of steam engine of the time, and there are
engineers' documents to back that up).
If anyone was a theoretician, it was Edison, who would get an idea,
and then spend a fortune trying to figure out how to implement it (eg,
the electric light bulb - he tested a mountain of different ideas before
one even came close to working). Tesla complained of Edison's
trial-and-error methods.
Tesla's ideas were fully developed realities, including engineering,
before he would attempt their building. Tesla pumps are the "Mercedes
Benz" of the industry, and his turbine, if allowed by the powers-that-be
(which is highly doubtful), will replace the piston engine, just for
starters.

A few? There are presently 358 billionaires in the world, and one trillionaire, all of whom conspire with each
other and against each other and us to control markets. Beneath them are MILLIONS of millionaire- wanna-be
billionaires, many more ruthless than their superiors, most of whom are involved in the same activities with
and against each other, and you and me. Ever seen the "pecking order" at a country club? Ever heard of
corporate "raiders" and "downsizing?" Ever seen the movie "Wall Street?" Ever heard of Ivan Boesky or Michael
Milkin, or Mr. Miller of AT&T, who just fired 40,000 people? Or the corporate raider who is charging Sunbeam
tens of millions of dollars to fire a slew of their people? Ever heard of the Exxon Valdez environmental
disaster and cover-up?

What I would suggest to you is that you find another hobby besides
blowing hot air at the truth. Try building one of these "impossible"
devices properly, and see how long you continue to "armchair critic"
your way around real people doing real work with their own money,
time, and energy.

Dear Don,
All I can say is "we'll see." Very smart guys can still have limited
views. My uncle Bob has a Mensa-rated IQ of 162, but I spent 3 hours one
time trying to show him that an eight-cylinder engine fires more than
once (he said only one spark plug fired each rev) per revolution. He
never accepted it, yet he wrote a valid, well-substantiated paper
mathematically proving that Einstein's theory of Special Relativity was
unsound, and he graduated from Tufts Univ. at the age of 19 in
engineering. We'll see.
Michael
Tesla turbines have reached efficiencies well over 60%, or double that
of the most efficient piston engines of today, most of which, because of
that high efficiency at a specific rpm, have very poor bottom end power.
But a 10" Tesla turbine capable of 15,000 rpm or more, must by nature of
that high engine speed, be geared down, probably 3:1, for a 5,000 rpm top
end at the output, and at the same time requires a minimal amount of
transmission gears, if any. Tesla engines have power characteristics
similar to DC electric motors, such as the starter motor in your car.
A Tesla turbine, geared down right off the bat by a 3:1 reduction gear,
with an adjustable intake nozzle, is capable of producing a tremendous
amount of torque and horsepower. Tesla speculated that his 110 hp
turbine, by using an adjustable intake nozzle, could possibly be capable
of approx. 1,000 hp in a short burst (and this from a small, very simple,
easily and inexpensively manufactured, very lightweight engine with ONE
moving part).
Michael
I assume that your question is serious. Two possible answers
Tesla's Response, 1916:
"Not a few technical men, very able in their special departments,
but dominated by a pedantic spirit and nearsighted, have asserted
that excepting the induction motor I have given to the world
little of practical use. This is a grievous mistake. A new
idea must not be judged by its immediate results. My
alternating system of power transmission came at a psychological
moment, as a long-sought answer to pressing industrial questions,
and altho considerable resistance had to be overcome and opposing
interests reconciled, as usual, the commercial introduction could
not be long delayed. Now compare this situation with that
confronting my turbine, for example. One should think that
so simple and beautiful an invention, possessing many features
of an ideal motor, should be adopted at once and, undoubtedly,
it would under similar conditions. But the prospective effect
of the rotating field was not to render worthless existing
machinery; on the contray, it was to give it additional value.
The system lent itself to new enterprise as well as to improvement
of the old. My turbine is an advance of a character entirely
different. It is a radical departure in the sense that its
success would mean the abandoment of the antiquated types of
prime movers on which billions of dollars have been spent.
Under such circumstances the progress must needs be slow
and perhaps the greatest impediment is encountered in the
prejudicial opinions created in the minds of experts by
organized opposition. Only the other day I had a dishearting
experience when I met my friend and former assistant, Charles
F. Scott, now professor of Electrical Engineering at Yale.
I had not seen him for a long time and was glad to have an
opportunity for a little chat at my office. Our conversation
naturally enough drifted on my turbine and I became heated
to a high degree. 'Scott,' I exclaimed, carried away by
the vision of a glorius future, 'my turbine will scrap
all the heat-engines in the world.' Scott stroked his
chin and looked away thougtfully, as though making a
mental calculation. 'That will make quite a pile of scrap,'
he said, and left without another word!"
Up until 1995, not so much as one disc turbine had been
reproduced in accordance to the Tesla specification.

Aw gee. 162 and descending...
I really like the bit about the 3 hours trying to show him, and the
fact that he never accepted it proves that both of you lacked a lot
of fundamental knowledge and *especially* an almost complete loss
of analytical and problem solving ability! Jeez, what's it take
to pop the cover off the dizzy, pull the plugs and rotate it by
hand? And the fact that a *FOUR* stroke engine with an *EIGHT*
cylinder configuration is likely to fire twice in a rev? Were it
not to do so, the power of a V8 would be lost on wasted piston
pumps...
Now, what about 5,6 and 12 cylinders? Only joking... I wouldn't
want to stress you too much.

Popular Mechanics! A real science mag that is. I have some copies

wierd CONCEPT stuff.
You know, (and you evidently don't), RADAR is merely and APPLICATION
of radio frequency transmission. You might fly a light model on
radiated power, but focus and collection really means you need
microwave frequencies. I'm sure the Scientists have poured
megabucks into such ideas to the testing stage.

Old OLD story, the HM carb. Especially considering that an engine's
fuel demand and combustion pattern doesn't change, that's a fallacy.
However, a HIGH PRECISION carburetor with computer control may well
pull in some savings. Actually, they call it FUEL INJECTION.
Sounds like another indicator that you are too confining in your
acquisition facts vs fiction.
>Free energy? Try http://www.livelinks.com/sumeria/free/lee.html
Yeah! What a screamer that was! I was having a good giggle over
that. It goes to show how inept some people are at business.
Phase change? Sure, a phase change can yield a LOT of energy -
but only because it has been stored. I have some phase change
devices right here in my hot little hand. Hot because if I
force a change from liquid to solid with just a nudge, it
gives up all its stored heat. Unfortunately, the reversal
takes heaps of energy.
Hell, If you believe as much of this tripe as it appears you
do, why don't you go straight to the FE/AG/SC source, Searl's
patented energy device? With one of those, you can not only
power your car, but it will also fly and keep you cool.

So, again, how do you measure the RPM? And excuse me, but who
has the facts and figures on the 10,000 psi, and was it liquid
or gas, and how thick was the tubing and where'd you get the
gauge? Or perhaps you *read* it someplace?

I don't think so. I also can do "real work" like shovelling
sand from hole A to hole B and back. It's a question of
whether you die of exhaustion before you realise you are
getting noplace.
If I accepted what little information you expect us to believe,
I'd preferably build a Searl supermagnet - its larger, shinier,
and it's claims transcend reality.

The wonder of the age still not on the market, hmmm.
There were certainly people arguing against Ovshinsky, but he also
pretty quickly showed some results.
Tesla's turbine, on the other hand, has been around lots longer and we
still don't see any results that show it is useful (economic, practical,
...) All we hear is rhetoric about how wonderful it is, with just enough
data to be tantalizing. A long time for it to stay at the tantalizing
stage.
No, it is called engineering - something Edison knew very little about.
Tesla was primarily a mechanical engineer by education. He designed the
first hydroelectric plant at Niagara Falls. He built 10,000 hp turbines
of his own design which worked - there are photos in existence of these
turbines, and texts of engineers noting them. He was a threat to anyone
who was making money from piston, bucket turbine, and bladed turbine
technology, and they were as against him for his bladeless turbine as
Edison (the king of direct current power for industry and the household)
was against him (and fought him) for his alternating current technology.

The 60% efficiency is probably mechanical efficiency - NOT thermal
efficiency which is what you are comparing it to. It is not possible for
the efficiency of the Tesla turbine to be as high as 60% - please explain
what the source and sink temperatures are to operate at this efficiency
and how you circumvent Carnot cycle laws!

Ok, so it's COMPACT, SPINS FAST and it's (ostensibly) SIMPLE.
That doesn't make it EFFICIENT. Everyone want's to measure
POUNDS, RPM, HORSEPOWER, where are the EFFICIENCY NUMBERS?
I have to agree, incomplete data sets are no more
than sales hype.

Indeed.
>Try http://www.execpc.com/~teba
A search for 'efficien' turns up repeated unquantified references
to 'improved efficiency', 'maximum efficiency', 'highly efficient',
etc. The only vaugly quantified reference is the following -
Tesla is well documented as stating that tests conducted utilizing
gasoline and water injection with the 110 HP version of the engine
achieved an efficiency of 60% at the engines output shaft!
which basically says 'Tesla said so'.

Unsubstantiated 'truth' is only so much 'hot air'. If you want to
call what you're doing 'real work' then do the work to really test
the thing. Otherwise call it a hobby and dont go around
grandstanding so.
gsp
Basically, you are extracting energy from some hot gas. How its
excracted and what the final form is is irrelevant. In this hot gas
there will always be a few particles that collide, thus canceling some
of the energy that could have otherwise been extracted. This is the
conspiracy we all must live with.
Now, electrochemistry is cool. Instead of extracting energy from some
hot gas, we can extract electrons directly from an electrochemical
reaction. ALL the electrons are usable, and the waste heat of the
reaction can be used as well. This is why anyone who understands a bit
of science is very interested in fuel cells, not Tesla turbines or any
other heat engine. The Tesla turbine might be easy to build and might
have alot of merits, but the reason its not widely used is very simple:
a combination of physics and economics.

If anyone knew fully concerning Mr Tesla's turbine and presented
complete data concerning it's performance to substantiate their
claims, we might not 'waste our time trying to fathom it'. Since
that has not occurred, we remain unconvinced.

Consider performing some efficiency measurements.
Don't mistake skepticism for personal anymosity, we're really
not 'out to get you' here. But people will not just
sit quietly in awe of Mr Tesla's genius without quantitative
evidence.

A thing can be simple to build, even elegant, 'effective' in certain
environments and yet not widely applicable.
Every time this subject comes up there is all manner of references
to RPM, LBs, and HP with various vaugaries to the effect of 'highly
efficient' but never any quantitative results. Ok, it spins fast,
that doesn't make it efficient. How about some complete numbers
to go with the rhetoric.

The TEBA or International Tesla society are the best sources I know of,
and have a lot of information available. Yes there are various turbines,
jet engines and pumps which employ the Tesla technology, many of them
patented. Some can be found through the TEBA. TEBA has posted numerous
times on this sight, once recently. A good start is to do a search on
"Tesla turbine" on the <search.com> or <metacrawler.com> sites.
Michael
Perhaps one of you geniuses will actually do the research people such as
the TEBA, International Tesla Society, and others like me have. I doubt
it. You're too busy "armchair critiquing" to bother. That's fine with me,
and probably everyone else who is working on this thing. More for us.
Now, back to your remotes, gentlemen.
Michael
Yup, I confess - you've caught us - no pulling the wool over eyes, Mark.
Everyone who has researched this and joined the "organization" (the Tesla
Mafia, la Tesla Nostra) actually has a fetish whereby they go about
seeking unsuspecting victims to join the ranks of the "fish" (that's a
code word for "insiders" - you must be psychic - otherwise , how could
you have come up with that "fishy" analogy). Obviously, you're "one of
us," but don't know it yet. The only way to find out for sure is to meet
with all of the other "dissenters" and take secret photos. "We'll" let
you know when to pass them on to "us." In the meantime, keep an eye
peeled. Go to every library in your area, and burn the Tesla books - that
way "we" can sell more of them. When you collect 13 library card jackets
from burned books, let "us" know, and we'll show you the secret handshake
for the "first level."

It is actually a thermocouple in your *gas* hot water heater. It is two different metals
joined together that produce a voltage when heated (and the other end stays cooler). I am
pretty sure all *gas* water heaters have them....they produce about 50 milivolts or so.
Now, when you link a bunch of these together, I *think* the configuration is called a
thermopyle, but maybe that is the wrong term.
In your *gas* hot water heater, the thermocouple is heated by the pilot light, and is used
to determine if the pilot light is lit, so you don't fill up your house with nat. gas.
Thermocouples can also make nifty high temperature probes - if you can calibrate them.

I've nothing bad at all to say about Tesla. Nothing. He lived,
however, at a time where competitiveness and efficiency weren't
really a critical element in design and application. That's not
his fault. So he made this turbine and patented it.
The problem I have, or rather, the brief itch I suffer, is to
see yet another device surface from the dimdark past and
be proclaimed so trascendingly efficient - not 5%, not 15%
not 25% - a massive 8:1 power to weight ratio against a
conventional self-contained combustion engine.
I agree compustion engines aren't efficient - but they are
cheap and their parts are easily maintained and replaced.

There is no real-world performance. I read nothing on the TEBA
page that represented real-world testing. All I saw was a lot
of talk - very similar to this net chit-chat. Luckily for you,
you have the opportunity to show the entire world how good this
device is. You won't do it, however, with factless ravings
about it.
I might well piss you off, but I'm only one of many that will
cause you to feel that way.
Good luck, I say. Do it if you can and tell us something REAL
so we can get excited too.

I realize that the "powers that be" have been infiltrated by claverns of
piston worshipers (worse even than scientologists) and that the efforts
by GM to produce a turbine powered auto were mere window dressing,
intended to make us THINK they wanted it to succeed but; If the Tesla
turbine is as simple and elegant as some here have maintained, I fully
expect to hear the anouncement of the Tesla Powered Auto Owners of
America Annual Road Rally where every Tesla fan whips together his own
power plant, grafts it into the family Buick and enters it in the
competition. Home shop machinists have converted Evinrudes and VWs to
run on steam and a hardy few have constructed the Screamin Demon and I
believe a few Schreckling (sp?) turbines. Surely we should see this high
efficiency beast implemented by an amateur not wedded to the piston
technology. C'mon, guys, what are we waiting for?

You indicated you have "a smaller one", smaller than a 10" unit. Were you
trying to clone Tesla's 6" turbine? From past posts, you had it up initially to
1500 rpm. Then you were able to coax it to 50000 rpm and lately to 70000. What
corrective steps did you take that enabled you to advance to this speed? An
enumeration of the problems you encountered on the way would be useful to the
novice who's likely to come across the same. What assumptions did you make
about your design that did not pan out in practice?

The valvular conduit is something of a mystery to me. I've seen a captioned

Interesting. O'Neill mentioned a 5" diameter model with 12 discs running
at 20,000 rpm on compressed air built by Tesla in 1906. I had almost forgotten
about this. Perhaps Advanced Dynamics patterned its engine after this? A
turbine is a bit much though just to power a solitary light bulb. Surely that
can't be the unit in peak form.
Sssshhhhh! You'll ruin the discussion by bringing _facts_ and _laws_

Actually, thank you. And yes, fuel cells are cool. I wish fuel cell
research were more of a priority. Cant make one in the garage on
grandpa's old lathe though.

Pogue invented a 200 mpg carburetor, attested to by Ford Motor Company, and
others. Say it doesn't exist all you want - there are probably still some around.
It ran on "white gas" (no additives). The oil companies put additives in
gasoline that rendered it ineffective. Golly, why would they want to do that?

Actually, fuel cells are good for some things, turbines are
good for other things, Diesel engines for yet other things,
photocells for still other things. What works best depends
on your application. There isn't so far, a universally
optimum powersource.
Fuel cells aren't particularely good for accelerating things
into low earth orbit, neither are Diesel engines for that
matter, but rocket engines which are basically combustion
chambers with an open end fed by the most incredible turbine
powered fuel pumps you ever saw, are good for that.
Once you are up there, though, photocells work really well
for harvesting light and converting it to other useful
energy forms, so can some forms of closed turbine systems
using concentrator reflectors. The shuttle uses fuel cells
for onboard power, they are silent, vibration free,
efficient, and expensive, as well as a turbine auxiliary
power unit which is not silent, not vibration free, also
expensive, and can deliver higher peak power for its weight
than the fuel cells.
The Space Station will use huge solar collectors - not
chosen casually, but selected based an a long and complex
tradeoff analysis considering cost, risk, experience with
the technology, availability, maintenance cost, etc. there
are solar turbine cycles that were also in the running, and
which may yet make it on to the station. The solar turbines
have higher power density, and are better for delivering
more power on orbit, but were not viewed as the best "only"
source of power on orbit when the station budget could only
afford one technology.
I'm not particularely familiar with the Tesla Turbines, but
their apparently high rpm may have held them back - most
common applications require some serious gears to couple up
to 50,000 + rpm prime movers. The Francis vertical turbines
used in hydroelectric applications turned slowly with high
torque, were easy to control, and had a *very* slow wear
rate. They may have other negative attributes that havn't
been publicized as widely as their positive ones.
Diesel engines however, because of better fuel efficiency
than gas engines (19:1 compression will always be more
efficient than 8:1 compression, other things being equal),
excellent torque low speed torque characteristics, and
simple support systems, make great tractor and heavy truck
engines, better than turbines for example. Turbine powered
trucks were tried and did not succeed. Big Diesels run at
relatively low rpm which helps to give them long life. They
are also heavy for their power output, and so not likely to
be used to power an airplane.
The process of selecting a technology for a particular
application is usually incredibly complicated and
constrained by a lot of factors not immediately obvious. It
is often, but not always, the case that proponents of a
"squashed by the evil corporations" technology are not
seeing, or don't want to see, the whole picture involving
the application of their favorite technology, or why their
favorite technology isn't the market leader for everything
using rotary motion.

God I love piston engines. Especially big 'ol Thumping
Diesels that burn warmed up bunker C with just the dinasouir

Even more amazing, though it might be disputed by the
turbine apostles, the math works for V8, flat eight,
strieght eight, radial eight, and double flat four eight,
cylinder engines, or two four cylinder engines direct
coupled together to make one big 8 cylinder engine -
regardless of the number of sparkplugs per cylinder or
valves per cylinder. (Though, that might get lost in the
more valves is better engines advertisements currently in
vogue.) Its known as the commutative property of cylinders
by professors of pistoncalculas.
Let me also add that based on the "data" presented so far,

should it? Oh well .....
Hey, I'm spinning my lathe in the garage as fast as I can! I KNOW there
are other guys (like Advanced Dynamics) who are working their butts off
as well. I've seen photos of the AD turbine - it's a work of art,
cranking out about 300 conservative hp from a 14"x3", 60-lb package.
Me, I started aout wanting just to build one for my Lumina - now, I can't
even begin to tell what I've got in mind. Grab your lathes, gentlemen.
The sky is the limit. Even if we screw up occasionally, it'll be an
adventure I'll never forget, or regret. I've got in my home the first
Tesla turbine of its type in the world, and it even sounds just like a
turbine when I crank it up. Ask yourself this. The runner in Tesla's
10", 110 hp, 55 lb turbine weighed about 20 lbs, most of it concentrated
towards the perimeter of its discs. How much momentum would you say that
it had turning at 15,000 rpm? Would you want to be the one popping the
clutch on that kind of power from a standstill, even if it was turned
off and just spinning, never mind if it was being pushed at maximum
efficiency by 25 spirals of expanding ignited fuel maybe 30-40 feet long
coiled up in the discs, grabbing onto them, like the closed plates of a
multiplate clutch in a motorcycle, at the same time? The AD turbine and
its runner discsare made of the best stainless steel they could get their
hands on. Tesla's 110 hp turbine had solid silver discs, and was never
pushed to its limit at 15,000 rpm. What do you think the AD turbine, with
high-tensile stainless discs can turn at? 20, 30,000 rpm's? More? What
kind of hp and momentum do you think would be generated by, say, 25 .030
thickness, 11" diam. stainless steel discs at that rpm? Would you want to
try to stop them? I wouldn't. How about a 5" runner turning at 60,000
rpm, in a turbine measuring 6" X 3" and weighing 35 lbs?
Michael
No one's. All of Tesla's patents have expired, and although two of the
pump companies seem to constantly suing each other for infringement of
"their" patents, Tesla's patents superceded them, and theirs are thus
virtually worthless. I have seen a film by the Tesla Memorial Foundation
of the Tesla Museum in Eastern Europe, in which there is an exact replica
of the designs they have put patents on shown, made by Tesla in the USA
when he was an American citizen (most of his adult life). This film
negates their patent rights (based on a turbine with bearings only on one
side of the "runner."
Michael
A T turbine doesn't need an adjustable nozzle unless it's going to be
pushed" to high short-burst output. Tesla's 110 hp version didn't have
ne. It's not part of the main body of the turbine, just the intake, and
for most purposes, probably would find little, if any, use in normal
driving in a vehicle. But it's the adjustable nozzle that can make a 110
hp turbine suddenly produce much more hp, or get very high gas mileage,
depending on it's setting. Mine doesn't have one - yet.
A "moving part" is usually not encompassing whatever form of air/fuel
device feeds an engine - but, if you want to include it, make it "2"
moving parts, but then there are the 2 bearings, which, if are roller, or
ball, could make it a 60-part engine. Whatever you like, it'll still
produce more hp/lb for its size, with no reciprocating masses, and no
need for a flywheel, than just about anything else around, and for less
money, and could be mass-produced right now.
Michael
I built a VC, and did some minor testing on it, and it worked. Enough
said. A much smaller TT will power that light bulb - don't assume that's
all the AD turbine would do - it's a scrap of a much bigger picture on
that 5" job, I'm sure.
Michael
Michael
I came in with facts, and I'll leave with the same ones.

Hey Mike, I just built one of these Tesla turbine things myself, and
it really works! I hooked it up to compressed air, and let her rip,
and it accelerated to over 130,000 rpm!
Unfortunately, my cat decided to play with it with his paw...needless
to say, the turbine and the cat are now in pieces all over my workshop.
I'll send anybody a picture of my dead cat for $20.

Keelynet! The foundation stone of the far-out!
Yeah, I just looked. 9% percent efficiency for the common
carburetor indeed! And pogues at 72%!
A properly flow-patterned and ratio'd air/gas mix will
deliver a particular explosion form and expansion rate
within a given cylinder/head combination. Reducing
the amount of fuel reduces the power that cylinder can
deliver. More air/gas mix in the same proportions
(as with turbo and superchargers) will increase the
power, while increasing only the fuel causes waste and unburnt
fuel (lacking the required oxygen) to pass out the exhaust.
I have read, about 8 months ago, that the only apparent
method of substantially increase in efficiency (for run of
the mill mass production cars) comes from direct cylinder injection.
Some vehicles already have this, but it is expensive.

Now, don't get silly. I've asked, aside from prodding for data,
specific questions about how you measured your RPMs and how
you'd quantify your claims regarding 10,000psi and 140,000 for
that 1 inch beastie. 10,000psi doesn't rise up from a
bicycle pump attached to scratching dog, you know.
>Pogue invented a 200 mpg carburetor, attested to by Ford Motor Company, and

Sure, Pogue invented things. Surely, an optimised fuel delivery
system can work wonders. But like electric cars which have a
distance problem, something operated by an expensive pogue device
is likely to crawl at a mighty slow pace. Hell, I've seen the
little bikes with their 50cc motors do mpg in the thousands, but
who'd pay so much to suffer such slowness?

Oh no. Not another conspiracy. You don't think there's more than

Well, stop talking, publish data.
I hate to say it, but there are a great number of turbine/jet devices
out there and a great many types of fuel vehicles can run on,
including alcohols, diesel, gases, petrol.
I'm sure Rolls-Royce and Pratt and Whitney and a few other
jet-turbine manufacturers have spent years on the game, and
wartime and post-war developments in jet engines and the like
have seen the whole gamut of development programs make
improvements.
I'd dearly love to see you build a 10 inch diameter tesla blade set
and without even building the engine, crank it to 100,000
rpm just to see what happens to it. Your claim of 70,000 rpm for
your home built machine just makes me wonder *HOW* you
measured it to be so and *HOW* you escaped injury.
You want to hint me about what material you used and who machined
and assembled it for you?

I've got the Machine Shop! Now somebody send me a set of prints on this
Telsa thing and I'll build it. If it works we'll all be happy. If it
doesn't then we will just throw it in the corner with the rest of my
Inventions that didn't quite cut the mustard.
At least then we can quit talking about it and move on to another
productive project!
All I've heard is talk, if it has any possibilities at all let's quit
talking and do something.

A small Nuclear reactor was placed in earth orbit and
operated there for a few months back in the sixties - it was
before 1969 for certain. It was called a SNAP reactor. The
reactor itself was not very big. The reactor worked fine, a
problem in the voltage regulation system in the host rocket
body caused it to shut down after about 90 days of
operation. The way it was designed, it could experience one
emergency shut down, but it couldn't be restarted.
Don't ask me if it is still up there, I don't know for sure.

<snip>
Well, I must say, its not particularely impressive in power
for its size as leading edge turbines go.
I've seen several (at least 12) turbine engines with 75 lb
rotors that can develop 75,000 HP. They are the drive
turbines that power the second stage fuel pump (liquid
hydrogen) for the Space Shuttle Main engine. The whole pump
including drive turbine is smaller and lighter than the
automatic transmission in my chevy Astro Van. They run off
liquid oxygen and liquid hydrogen. The pumps they drive can
empty the average swimming pool in about 20 seconds or so
and deliver the water at greater than 2,500 psi. (While I'm
in statistics mode - consider that the space Shuttle Main
Engine has fuel pumps - yup, just getting the stuff into the
chamber - that develop well over 100,000 horse power and run
with casings cherry red with liquid hydrogen and Oxygen
flowing into them - the temperature gradient problem from
hell - the analysis tools used to understand it and predict
it with precision are awsome - the metalurgy is more like
black magic.) The pump bearings are hydrostatic - I believe
the fluid (lubricant) is liquid hydrogen. Just getting one
of these started with out blowing it to bits is *not* easy.
Those turbines have been around for a while now - they were
on the first shuttle flights of course. NASA has spent way
over a billion dollars with another company trying to build
a better one. The improved version (heavier) hasn't flown
on the shuttle yet.
I suppose I should get all excited and propose putting them
everyplace - one the size of a watch should drive a car for
example. Trust me on this - you do *not* want one of these
in your car.

My opinions are my own, and do not represent those of the
company I work for - and this was sent from home - I *never*

Tesla turbines will run on any moving or expanding fluid or gas. One
built to run on petrol or diesel can be fueled at any petrol station
delivering at least double the mileage of your average piston engine,
much more reliably, quietly, without the need for smog devices. I really
wish that someone would provide thoughtful, logical questions about this.
It's really getting boring here trying to think for people and answer
their dumb arguments. I mean, I like the sound of a big V8 as much as the
next guy, but there's no way it can compete with an elegant mechanical
design which was never given an opportunity to flourish for the same
reason then as are apparent now - an obstinate, uninformed public most of
which cannot even conceive of how this thing works, nevermind argue
against it validly. I'm working with one of Bill Lear's best men - you
know Lear, Lear Jet, Motorola, the Lear closed system steam engine? The
man tells me this turbine can change the world, and from my own personal
experience with the turbine, I have to agree with him 200%, and you

Well, golle, I don't know about anyone else, but I'm totally impressed.
How much did you say NASA spent on that engine? Probably about as much as
it would cost to built 1000 replicas of the AD engine. And that 14x3
dimension I gave you is the size of the entire engine, not its runner. I
tell you what. Why don't you build a replica of that NASA engine. Let me
know when you're done.

It wasn't. There were three experimental devices that were steps
towards it, but there has never been an aircraft that flew with any
form of nuclear power generation on board. Probably the closest was
one of the Oak Ridge experimental reactors (sorry, forgotten the name)
which never flew, but did leave the ground - it was operated by remote
control, hung 300' in the air from a few towers and cables. A B36 flew
with an operational reactor of the same type on board, but no real

be exactly the answer another puzzle was looking for. So, I say, pursuing
some of the arcane, forgotten, or inadequately investigated "technologies"

If it was not so entertaining, I would have killed this thread ages ago,
but it is better than a TV sitcom.
Mind you the tesla guys are starting to repeat themselves a bit, is this
a re-run. I must buy the book and see who wins in the end.

Petard, hoist by. See "pot calling kettle black"
A V8 4 stroke will fire _four_ times a revolution, not twice.

>of the most efficient piston engines of today,
Irrelevant argument. Turbines are already efficient, but that doesn't
mean that an overall power unit is going to be efficient. If a Tesla
turbine could be built into a complete gas turbine vehicle powerplant
that didn't need a regenerator, didn't have exhaust temperatures that
would roast following vehicles, and didn't have the fuel consumption
of an M1 Abrams, then they might be a little more magical.
This is going to take more than an efficient turbine core though.

What wattage bulb? Or at what voltage and current rating? Running the
motor on what CFM of air at this pressure? With what efficiency of
generator and geartrain? That would go much further to telling us what
we are asking to know than all this posturing and paranoia we've been
hearing from some of your members lately.

There is (or was 20 years ago) a big railroad engine repair shop
in Wyoming. There were 100's of deisels all waiting to be repaired
there, all idling (because the pain of restarting one of 'em was more
than the cost of idling it). Resonance being what it is (two or more
oscilators, lightly coupled, will tend to oscilate in phase after a
time) the sound and vibration in the ground from a hilltop about
a 1/4 mile away were VERY awe inspiring...

Fine. Just answer ONE question: what equipment you used to measure
your 70,000 rpm.

I really wish you wouldn't be so smug. Particularly ironic is the
assertion that you 'really wish that someone would provide, thoughtful,
logical questions' while you completely ignore every request to
quantify the efficiency of the Tesla wonder device.
Enough with the generalities. Quantify!
