I was also considering salvaged platters from disk drives,
the 5.25" variety actually.

Except I was going to drive them with a high speed motor
and A) get compressed air for an air brush, or B) use it
as a vacuum pump, depending on airline arrangements.

I'm still in the parts-gathering stage, I have sufficient
platters for a start but I'll want more.

I figured one of the $10 trim routers from eBay would run
things at 30,000 RPM for short term, then the motor would
burn out. If the 5K rated disks didn't explode first.

Obviously, a sturdy enclosure with a good scattershield
is called for. Or maybe instead, use a washing machine
motor and gear things up less dramatically with a series
of pulleys.

Any thoughts on the design?

I would love to hear thoughts and where possible, specs
on extant turbines this size.

You are correct about what happens on a rainy day.  The higher the humidity the lower the power output.  It doesn't explain the results that I had though.  I fly ultralights  with two and four stroke engines.  On days when the humidity is over 75% the engine puts out less power and the plane is sluggish to control responses, the air is less dense.

Back in Physics class in college, the Prof did some math on how a car
engine behaves during a rainstorm.

As I recall, he showed that when the air is saturated with moisture,
the excess H20 being fed into the engine actually displaces O2 reducing
the power output, and also sucking up power by absorbing heat from the
engine.

Thus the reason that a car's engine settles down and purrs when it's
foggy out.   Less power, less noise.

Internal combustion Engines are somewhat delicate as we all know.    An
engine operated at altitude needs compressed air to keep working.

As you mention, injecting H20 vapor into an engine can help it run
cooler.

The irony about: "engines that the military used would begin to
detonate at very high power settings"  is that today there's serious
development going on to harness "Pulse Detonation" as a way of getting
more power in aviation engines.

Kind of like riding a bomb.  Actually, exactly like riding a bomb.


As for cracking the water to get H2, recall that you can't get more
power out than you put in.   There's no catalyst that I know of that
could cheat the cost of cracking water 'in situ'.


And Internal Combustion Engines don't generally get to 3,000 degrees.  
I did a Google search but couldn't lock down the actual temps that H20
dis-associates.


I really like the idea you quote about the water vapor increasing the
compression in the engine.   More compression, running cooler, would
certainly change the behavior of the engine enough to notice.

Well, I'm not a pilot !   But... is the muggy air actually less dense ?
    There's less O2 per cubic foot because the water vapor is occupying
space and therefore displacing Oxygen.

Air density does vary with altitude and temperature, of course.

As far as interpreting results... well, it's all a matter of
interpretation.

Tesla was one of the greatest inventors of all time.   But he was
taught that energy is transfered via 'the ether' and never let that go.

Which meant that he could invent a lot of great gadgets;  but his
ability to understand the processes and predict outcomes was limited.

For those who don't recognize this term, in the 19th century the
prevailing view of the Universe was that all energy has to be carried
by a particle of some kind.

Light, for example, would be carried by the 'ether', a field of
infinitismal particles that saturate space.

Light energy  from the Sun bumps into the Etheric Particles in Space,
and the light wave is thus a wave travelling through the medium of the
Ether.    Just as in the ocean, a wave is energy carried through the
medium of seawater.

There was a test way back when to prove the existence of the Ether.
It failed.

But it was a well designed test.   The theory was that if the Ether
permeates space, it must act as a fluid.   As the Earth passes through
this fluid, it must create a wake.

So the experimenters set up a system of light beams rigged to measure
this wake.  They got nothin'.

Because there was no wake to detect.

But Tesla, despite his rep for challenging authority, stuck with this
idea of the Ether.

I often wonder what he might have accomplished if he'd just let that
go.   And if he'd had a financial manager.

If you have any curiousity about the density of the air at different temps, barometric pressures and humidity levels go to   http://wahiduddin.net/calc/calc_da.htm  You can see the relationships between temp, press. and humidity and the effects that they have on absolute pressure.

Hi,
 
In Verona (Italy), we are going to start a Tesla Turbine project.
 
The turbine will work with a low temperature condensing fluid in order to acheive the maximum thermodynamic efficiency.
 
We need a detailed methods of calculation of efficiency in function of every variable ( space, pressure, fuid, etc.)
I need informations and opinions about those calculations methods
 
Before to start building the turbine we need to know the efficiency we can acheive ( we will build a program).
 
Every idea and comment is useful,
 
thank you

You might want to examine the use of CO2. It's a liquid at room temperature around 400 PSI. Should make a great low temperature working fluid.

Tesla Energy Overunity Prototype Works for 3 Years;

MP3 Download (0:53:44)

This is the Tesla energy invention we've all be waiting
for! It is called the Lutec 1000.

Inventor Lu Brits first developed the concept for his
Zero Point Energy device 20 years ago, while working on
a maglev train project.

For the last three years, his overunity prototype has
been working like a stuck slot machine.

It is generating 1500% more energy "out" than the
amount of energy "in" needed to energize the circuit.

In this history-making interview, Lu explains the
various components of the Lutec 1000 and how it works
in precise detail.

What amazes us is that Lu and his partner are still
alive, because this device really does work! Let's hope
he can get it to market before the oil interests crush
humanity's first real hope for free, clean, unlimited
energy.

Hi,

I have just been accepted to Medical School and I have to sell my
Tesla Turbine. I will have no time or money to work on the project.
I have pictures already posted (side view, top view, etc). The unit
is made from stainless and has designed, built and assembled in a
machine shop all parts are CNC'd machined. I do not have the
blueprints anymore but the unit does work. I have done limited
testing with air and low-pressure steam. I also have a parabolic
solar panel available it is approximately 3 feet by 10 feet and
generates so impressive steam. Additionally there is a 50-gallon
drum flash tube boiler and 500000 BTU propane torch that goes with
the package. All the items you need to start testing and playing
with a Tesla Turbine.  The unit is in Phoenix, Arizona so
arrangements would nave to be made for pick up. The machining and
materials cost well over 3500 dollars so serious inquiries only. I
will be moving to Northern CA for the next four years so it has to
go.

Thanks.

Jim,

 

Thanks for this information. The links were very informative.

 

I have a follow on question…

 

Besides the hassle of designing something new, can anyone see a down side to integrating a motor into each wheel hub instead of having a separate drive motor? I envision that the DC motor housing itself would be the mounting point for each tire. There would be no need for powered input shaft, as all drive would come from inside the hub. All drive train would be removed. Power train would consist of a DC power plant that would vary its output to meet the current vehicle demands, the wires that went to each wheel, and the wheels themselves. I’m not sure if this is clear, perhaps I should make a drawing…

 

Any thoughts?

    The only problem I see with that idea is getting all the motors synced together. I would think even a slight difference in wheel speed would cause the car to pull, and tires to wear unevenly.
   That being said it's certainly possible to accomplish, but I have no idea how without some sort of computer control.  Properly controlled I think individual motors would be the ultimate in traction control. Well those are my thoughts.

Besides the hassle of designing something new, can anyone see a down side to integrating a motor into each wheel hub instead of having a separate drive motor? I envision that the DC motor housing itself would be the mounting point for each tire. There would be no need for powered input shaft, as all drive would come from inside the hub. All drive train would be removed. Power train would consist of a DC power plant that would vary its output to meet the current vehicle demands, the wires that went to each wheel, and the wheels themselves. I’m not sure if this is clear, perhaps I should make a drawing…

 

Any thoughts?

    The only problem I see with that idea is getting all the motors synced together. I would think even a slight difference in wheel speed would cause the car to pull, and tires to wear unevenly.

   That being said it's certainly possible to accomplish, but I have no idea how without some sort of computer control.  Properly controlled I think individual motors would be the ultimate in traction control. Well those are my thoughts.

It is a simple matter for the drive controller to “synchronize” the speeds of the various motors.  That is precisely what traction control does on mechanically driven cars.  That is also part of what happens in the ABS system on modern brakes.  Rotational speed sensors on each wheel transmit the wheel PRM to the controller, and the controller supplies more or less force as needed to keep rotational speeds the same on each wheel.  Doing the same thing with power proportioning electronically is much easier than proportioning hydraulic pressure to brakes or mechanical power to drive wheels.

 

Also, thanks to James Welsh for agreeing with my proposal on driving the car totally electrically, with no mechanical connection to the drive wheels from the powerplant.  That would save an untold amount of weight and mechanical complexity.  I have always felt that the simpler it system is, the easier it is to maintain.  That is why I proposed a gas turbine as the power plant and not a reciprocating engine of any kind.  A gas turbine is much smaller, lighter in weight, more powerful and has but a single moving part.

Sorry if i sound new to this but i lost a bunch of
emails. Has anyone thought about making a street legal
version of this dragster?(excuse my terminology) It
seems that if done correctly it could make for a very
efficeint street veichle and would not be to hard to
to pull off, at least in the catagory of experimental
cars. I will also echo the aproval of "no mechanical
transfer of energy from the power plant to the wheel".
If you look at plans for the SEGWAY human transporter
it has a inhub electrical motor design and it seem to
work quite well. Also the potential for a noslip AWD
is incredible because traction controll is so much
easier if you can generate the exact amount of force
needed to maintain control (this could also lead to
less tire wear in cornering expecially if combined
with the Bose suspension system). So Please tell me if
i am wrong but this could be a completly new wave of
automotive technology. Thats all of my rant for now.
And if yuo need a machineist to look plans over or
prototype a part let me know.

Ed,

Good to hear from you. I actually wasn't planning a dragster, I'm more
looking to build a street legal vehicle for myself. I have hydroelectric
capability on my land, so that means pretty near free hydrogen for as
long as it rains. This business in California of paying $2.79 a gallon
for gasoline is for the birds and I don't see it getting any cheaper!

Thanks for sounding off about the machining. Looks like I should
definitely start doing some more concrete figures and maybe we can start
working on some of this stuff.

Is anybody on this list a thermal dynamics guru? I don't know enough
about metallurgy to select the proper material for my turbine disks. I
can look up some information about the firing temp for hydrogen
catalyzed with Oxygen, but I don't know enough about thermal buildup and
plastic states of metals. I don't want to go through the trouble of
designing and building just to have my disks deteriorate faster than you
can say "no slip boundary layer."

So I guess the starting point would be to take a swag at the overall
vehicle weight, determine what sort of acceleration and cruising
characteristics we would want it to have, and use this to figure the
torque and horsepower requirements of DC motors. This would get us to
the required output for the power plant. Throw in a dash of fudge factor
for efficiency losses and I think we are there.

Am I missing anything?

Oh, and I was thinking, does anybody know any down sides to the old
Unibody designs? I remember a friend telling me how they could drive on
mud easily because the car was so light. If this is the case, we could
also reduce weight here by doing away with the chassis. Also, since each
wheel will be driving part of the car, I don't think that there will be
as much lateral torque applied across the vehicle...

On the other hand, we couldn't skimp too much because the passenger
compartment needs to be crash safe.

Who knows about crumple zones and using twisted metal to soften the
imparted forces of a vehicular accident?

Any other thoughts?

In thinking about this design, I wanted to make the vehicle green (use
alternative fuels) but make it have outstanding performance. Like a
little muscle car. I'm thinking that I want to feel like I'm sitting in
a fighter plane. I think this could be pretty neat, especially if the
Tesla Turbines put out the high pitch whine I'm expecting. The more I
have thought about it, the more my hydro-electric ;) car looks like a
formula 1 race car... hmmm. Anyway... I'm just trying to keep it FUN!

Here's a hat tip to Jim Dooley... In talking about all of this, I have
adopted ideas that sounded good into my own thinking, so, if I take
ownership of an idea you have had, I'm not trying to take credit, I'm
trying to flatter you by agreeing that it's an awesome idea.

I'm seriously not interested in paying these ridiculous gas prices and,
if we have the technology to make alternative fuels work, I say we
should. A large stumbling block is that there is so much knowledge that
goes into this sort of thing in order to make it work, that it's really
difficult for one person to do it and be altogether successful,
especially if he has anything else going on in his life. So... if we can
work together and make this happen, that's awesome. I'm down to put some
of my time toward this and even some resources, but I'm definitely going
to need help.

I offer my apologies to any women who may be on this list. My use of the
work He and him are completely non gender specific.

Heres a thought, If you are thinking about using a
unibody design you could always retrofit another car
to work for you thus simplifing the safty and comfort
issues. I am a Subaru fanatic so excuse my excesive
subaru/AWD comments. You could use a 90's plus subaru
to build on I have torn one almost completly apart and
put another one together. Great unibody, down side
engine and all it weighs in at 3500lbs, mostly the
fact that unibodies are great in mud is true, but not
for the weight, mostly because they have almost
nothing to catch on the bottom with. Also Sizes are
easy to match, almost everything is metric.(I am in
the US) But Toyota Corolla's are much lighter no
complicated AWD and a really light unibody, I dont
have a specific number though. Also if you can get me
your running and peak tematures I can tell you what
you need to make the discs/housing out of. one of the
Guys in the machine shop is a metalurgy guru.(Just a
note the machine shop is not a garage shop we have 2
CNC lathes and 3 CNC mills. The Point is the quality
of work will be the best you can get. Anyway thats my
rant for the evening.

Have we got any thoughts?  Some of us are blessed
[cursed] with as many thoughts as there are seconds in
our lives… [smiles].

The question is,  “Are any of our thoughts of any
value to what you are trying to do?”  It would seem
you do think some of the ideas on this site are of
value.  [smiles]  Well, since you are weighing that
one out for yourself, here are my contributions:

--- NOTE: for lack of tabs on most blogs, I am using
the following outline format, sorry if it is a bit
hard to get used to… :{

1 Design the blades out of ceramics.
1.1 Lightweight, ultra-high temp, easy to shape, like
the infamous Shuttle tiles.
2 Design the motor to run at “One RPM” and load.
(higher RPM=smaller diameter and higher torque [or
lower breaking horsepower])
2.1 “One RPM” will allow you to maximize efficiency
while higher RPMs will make the whine or bearing drag
an important factor [but no air bearings, see 4.4.1
below].
2.2 “One RPM” is practical because the motor will only
drive an electric generator.
3 If you think you will use electrolysis, look before
you leap, but if you do go that route, you can use
both the O2 and the H2.  Electrolysis is a teaching
demonstration that is not generally used in industry
for H2 production for some good reasons.
3.1 One alternative method is to use the electricity
to make steam [using preheated water from a
solar-water-heater?].  Pass the steam over catalysts,
which will break steam into O2 and H2.  To research
more details for that method, look for documentation
of the common industrial production methods for H2.
3.2 Another alternative is to just charge batteries
with your hydropower electricity, forget the H2 part…
Oops, that’s right, charging car batteries creates H2
and I guess you really did have your heart set on
hearing the Tesla Turbine whine a bit.
3.3 To get really far out, I think Dr. Tesla would
have designed a high frequency, high voltage generator
for your micro-hydro-power-plant and beamed the power
to the car.  I have no idea how to design a microwave
or X-Ray frequency hydro-generator.  I would
experiment with microwave ovens, but that could be
quite hazardous for any but the real Dr. Tesla types,
I am not that qualified.  Again, this idea gets away
from the turbine idea unless the water is used to
drive a high-speed turbine that in turn, drives a
high-frequency and high-voltage generator.
4 If you like the idea of using an existing car
chassis, and throw away the wheels, drive shafts,
rear-end and transmission, ditch the suspension as
well, see the Hummer thought below.  This will leave
the steering and brakes hanging!
4.1 You might also get rid of the back seat, use that
area for heavy batteries in order to keep them as
close to the center of car as is practical.  You
should also put special attention to lowering the
center of gravity with the battery placement.  The
reason you probably want
main-motor-to-generator-to-batteries-to-controller-to-wheel-motor
configuration is that you can then have very high
torques for when the light first turns green, while
critically tuning the main motor for the average power
needs and then the batteries have to be just large
enough amps to do the power averaging.
4.1.1  100hp=75kw for our calculations  [100hp =
74570.10335416 volt-amperes].
4.1.1.1 [1/2 motor rating] – [average target hp] =
[battery size in hp]
4.1.1.2 but… you also want the motor rating and the
battery rating [in hp] to be to be equal so that the
other half of the motor rating [in hp] can recharge
the batteries.
4.1.1.3 A plot of “normal” hp usage over time would
probably not be a bell-shaped curve.  The curve may
have substantial kurtosis [plot table one] and table
one still has an average hp of about 100hp.  For that
reason you may have to consider another battery
specification, technically known as internal
resistance, but generally spec’ed as cranking amps for
car batteries.  The battery may well have 10k
amp-hours [X coulombs] but you generally cannot get
all them electrons out of the battery in one second!
Therefore, this factor will effectively limit your
peak hp [or fun factor].  The limit of electrons per
second [amps] that a battery will supply at a working
voltage recalculates to an effective internal
resistance - according to Ohm’s Law:
E [voltage] / I [amps] = R [ohms] or, for example:
   12volts / 100amps = 0.12ohms
       [or sometimes spec’ed in terms of conductance:
1/R=G, 8 1/3 Mhos]
4.1.1.4  Yet another, but similar sounding, concern is
that you cannot put all the electrons back into a
battery in one second.  The example battery may not be
able to be charged at a rate of 100 amps, even with an
additional 2 volts [14v total] of charging pressure
[too much pressure, in volts, can cause a battery to
melt, rupture or explode].  A typical battery charger
will control the charge rate via a current [amp]
limiting feature.  This will also factor into your
calculations of how many batteries and what kind of
batteries you think you need.
4.2 You may need to check that the efficiency loss due
to the weight of the batteries will be less than the
increased efficiency effect of the tuned motor design.
  My intuition would say that is true by a considerable
margin, but in reality, many design factors affect
that answer!  The smaller or no battery compromised
design would have to compromise main-motor efficiency
for increased maximum power and the ability to operate
reliably over some range of RPMs and loads.
4.3 Perhaps you can use small stock tires, but thin
hard rubber tires would be more efficient.  Long-haul
trucks use “highway” tires, hard rubber treads, for
both increased tire mileage and better fuel economy
with the design sacrifice of longer stopping
distances.  Make sure that the tires you choose, will
stop you safely as well as provide some desired
fun-factors [acceleration, road conditions, usage,
etc.]: slicks, mud treads, aircraft tires, monster
tires, mini-spare-tires, etc.
4.4 Design a new wheel with 25 to 100 hp electric
motors in the center.  You did say fun, right?  The
power actually transferred to the wheels will be
outstanding compared to a “normal” car.  Vettes and
Hummers beware!  They are able to transmit some
percentage of the engine power to the wheels.  Your
four 25hp motors may be able to propel you faster than
a Vette and get more air time than Bigfoot, let alone
the pricey Hummer [albeit your buggy will not be cheap
in its one-off version].
4.4.1 Design the bearings to allow the car to be
suspended from the four motors [not only the weight of
the car, but the weight times the maximum forces,
i.e., stopping, starting and centrifugal].  This will
translate to very heavy-duty bearings, notice that all
“normal” car wheel bearings look like the same design
because that design is an inherently very heavy-duty
design.
4.4.2 Standard practice would use permanent-magnet DC
motors, but I would design a Tesla style [brushless]
high-frequency “Polyphase” motor [much like an
oversized stepper motor] then bring out all the leads
to the motor-control, which will be able to control
the motor [effectively re-wiring the motor] for high
torque and smoothly transition it [with several
in-between modes] into high-speed [low-torque] mode.
Lots of wires going to many different motor windings
will have the added advantage of making the finial
wire gauge and the motor control elements, much more
practical, i.e., affordable, as well as increasing the
reliability via semi-redundant elements [one wire
breaks and you still go, if less efficiently].  The
idea of using electric motor control instead of a
mechanical transmission is from the well-proven
diesel-electric locomotive designs [this means
enormous and efficient torque by design].
4.4.3 Do not forget to include a braking system in the
wheel design, regenerative breaking will help, but the
overall design should be able to stop about as fast as
it starts.  It seems wrong to use electric power for
stopping, but that could be done by designing the
motor-control with some special heavy-duty braking
algorithm [thus you would not need the hydraulic
braking system from the stock car].  I think I would
stick with the old system just for the time proven
safety factor.
4.4.3.1 Hah yes, you will also want a parking brake,
with all of the electricity off, you would not want
your creation to seek a lower level all by itself.
4.4.4  As you design the suspension system which
connects the motor/wheels to the chassis, do not
forget to allow for re-connecting the steering.
4.4.4.1 Hummer idea: since the mechanical drivelines
are gone, the suspension design can be rather radical.
  It will be much easier to design far greater
up-and-down-travel with variable shock absorption.  I
would use an air-assisted shock system controlled by
added circuits in the main motor control box.  The
motor-control will have some type of anti-slip control
for each wheel; to add independent suspension control
will enhance that performance.  I could see this thing
able to transverse a course of boulders while
remaining level owing to a radical suspension design
and controller with level sensing.  As I envision it,
this design could work better than a Hummer for rugged
terrain demonstrations, i.e. during and after
Armageddon, DARPA grant money anyone?
5 If you simply want a novelty gadget, you might get
some limited utility out of designing the Tesla
turbines into the wheels [instead of Tesla’s Polyphase
electric motors].

Plasma Torch type furnaces
	 or
Garbage in Energy out

The GEET introduction talks about using exhaust to
heat the fuel.
The GEET introduction also talks about cold air and
hot air electrostatic charge buildup.
Ostensively the electrostatic charges and the
temperatures created could create plasmas.

I have looked into some available and working plasma
torch furnaces, a good web site is:
