Every now and then a an idea comes along that will change the world -
and gets mostly ignored. Some of you have heard me talking about this
new air powered car from MDI (Moteur Developpment International) in
France which is now to be manufactured by Tata Motors of India.

MDI did a press release a few weeks back and it was handled like,
well, another press release. The automotive press paraphrased a few
paragraphs, but I wonder if they actually THOUGHT ABOUT what they
wrote?

And when Tata Motors introduced their more conventional yet
inexpensive Nano at the Detroit Auto Show last week, it got amazing
coverage, but not ONE mention of this new air car to be manufactured
by the very SAME company!

The highly touted Tata Nano is a cute little bug that will get more
than 50 MPG - cool. But the MDI OneCat which is about the same size
will go more than 20 TIMES farther on the same gallon of fuel! Did no
one actually READ the spec sheet on the OneCAT?

To be fair, the objective of the Nano is low price, not mileage. And
the OneCat is much lighter, which helps, but surprisingly, that's not
the key to it's mileage advantage. Here's how they do it...

As almost everyone knows, the standard internal combustion engine is
only about 30% efficient under the very best of conditions. This means
70% of the energy in a gallon of gasoline leaves the car as wasted
heat.

The only heat that produces power is that narrow band of highest
temperature that causes rapid expansion of air when the spark plug
fires. Once the piston reaches the bottom of it's cycle, all the lower
temperature energy from that cycle is wasted and must be pumped out
the exhaust pipe.

If you add MORE heat at the point of ignition (higher octane), you get
more power. But Newton and his second law of thermodynamics limits us
from using any of the heat BELOW the temperature of ignition. THAT is
the primary reason for the inefficiency of the internal combustion
engine. But what if we COULD use ALL of that heat?


CAT - Compressed Air Technology

Guy Negre of Formula 1 fame and his company, Moteur Developpment
International have spent the last 14 years developing a new type of
engine for automobiles.

Compressed Air Technology has been described as using air as fuel, but
that's not quite right. The air works more like a battery. It actually
uses a carbon-fiber air tank with up to 300 times normal atmospheric
pressure driving a piston to give the car a range of 100 Km. You can
think of this system as a standard compressor motor and air tank -
except it's running backwards. The air tank drives the compressor,
instead of the other way around.

So far, no big deal. Any advantage is a matter of strength, weight and
volume per unit of energy stored in the "battery" - the carbon-fiber
tanks helps some. But if a short range compressed air car is all they
had, it wouldn't be very impressive. The next detail is the key. When
you think about it, you'll discover it's the biggest advancement in
thermal energy extraction since the invention of the Otto-cycle in
1860! It effectively uses "wasted heat".


Bi-Energy Breakthrough

Guy Negre's brilliant innovation is to add a small fuel burner between
the air tank and the motor. The heat from this burner extends the
range for the compressed air tank by increasing the pressure of the
air even more on it's way to the motor. Properly insulated, this
burner could approach 100% conversion efficiency of the burned fuel.
Here's the reason...

Small amounts of heat are not enough to turn over a reciprocating
motor. But when you add a compressed air tank, it provides a pressure
bias great enough to drive the motor on it's own. Now add the burner.
Per the gas laws, the pressure increase is proportional to the heat
added - it doesn't require a critical temperature of ignition! You
could run it tepid or boiling - ANY heat adds power. It's just a
matter of how much.

If you double the burn rate, you'll double the added expansion. Since
there's no point of ignition, there's no critical temperature before
this energy is extracted. ANY heat added by a burner (or other source)
will simply add proportional expansion and energy extraction.
Theoretically, most of the energy from a gallon of gasoline (or stack
of firewood) could be used to drive the motor.

Check the spec sheet above. I assume these are actual measurements.
The OneCAT will go 100 Km on air alone, but another 700 Km on only 1.5
liters of fuel! That works out to almost 1100 MPG!


More Than JUST an Amazing New Car

MDI has a good chance of creating an amazingly efficient little car,
and that's cool. But what's REALLY exciting are all the other
potential industrial applications.

Considering generation and line losses when producing electricity, it
may even now be more efficient to run Bi-Energy motors at the site of
the application instead of buying electricity. Or we could boost power
from solar heating. Or hot sewer water for that matter! ANY source of
heat could be used. It's just a matter of degree and effectiveness.
Any of a thousand sources of wasted heat can now be used.

OK. You'll still need electricity to provide the compressed air bias,
but the rest of the energy would be more efficiently extracted - the
hotter, the better. What about recycling the heat from air
conditioners to drive their OWN motors? I'm not talking about
perpetual motion here. There's no free ride. It's just that the heat
is no longer has to be totally wasted. This approach provides an
excellent possibility of dramatically increased efficiency in anything
that needs a rotating motor and has wasted heat available. (Note - MDI
was WAY ahead of me - I just found this link on their site... Further
Applications - WOW!)

These ideas are worth more than just a press release. We need a new
college of engineering at every university!

It's a whole new way of thinking about energy!

14 years in development, multiple evolving multi-stage versions of the
air motor, video of operating prototypes, a contract to manufacture
with an operating car company. What do you need just to consider the
technology?

Why exactly? You sound like you might be an expert on what is
idiotic.

> 4,500 PSI tank with a flame on it ? It will go some where fast.

Now that WOULD be silly. The burner is just before the decompression
stage where it does the most good. And if I remember the gas laws
from chemistry correctly, pressure is proportional to temperature, and
in this case pressure produces rotation which is the definition of an
external combustion engine. In some ways it's not that different from
a steam engine. It just uses nitrogen and oxygen instead of water
vapor. Why is this so difficult to understand?

I admit it. I'm not an expert with this. So I'm asking, where is the
hole in their logic.

What's wrong with their spec sheet?

Are these prototypes an illusion?

Indeed. A history of FAILURE.

The basic science is all that's needed to show that an 'air motor' is a stupid

Says who? There are plenty of Sterling cycle engines which run at
temperature differences of tens of degrees or less. They are very
inefficient but can generate power. In practice car engine efficiency
is limited by the ability of materials to withstand high temperatures.
We're miles away from the theoretical Carnot efficieny.

It does appear to imply that, but in fact only says it uses 1.5l of
petrol, which is meaningless without a distance.

You're saying it violates the 2nd law:

This is just as unlikely as a perpetual motion machine.

I can't see any concept here that wouldn't have been thought of 200
years ago when people were struggling to get the most efficiency from
their heat engines. They're not proposing ceramic cylinders or fancy
fuels, or even new science. Just bog standard expansion of hot gasses
and bog standard compressed air, the same as is used in industry every
day.

This might be good for the Indians -- the general issue
is that it gets very hot down there, and a tank full of
compressed air will inherently chill down.

However, let's look at the problem from an energy density
perspective.

Take a 15 gallon tank. Gasoline has a density of about
130 MJ/gallon. That tank therefore contains almost 2 GJ.

Pure ethanol runs 24 MJ/liter; one gets 1.36 GJ for that tank,
plus some unwanted extras if one accidentally introduces water
(ethanol is hydrophilic; gasoline hydrophobic).

Liquid hydrogen is 10.1 MJ/liter -- 0.57 GJ for that tank,
and some complicated engineering to keep it from evaporating
and exploding. (Research is in progress, AIUI.)

Anthracite coal is 72.4 MJ/liter, which would actually
make for a fair amount of efficiency except that most
fuel systems don't handle solids very well, even sinterized
ones. :-) That gives 4.11 GJ for the tank.

I won't bother with uranium.

Compressed air at 300 bar is given at 140 kJ/liter, or
0.008 GJ for that tank. (300 bar = 4351 psi.) As a check,
one can compute the amount of energy pushing a piston
of area 1 m^2 from a position of 17 meters out to 0.05678 meters out
(since 15 gal = 0.05678m^3). That's

integral(x = 0.05678 to 17) (PV/x dx)

(remember that I'm assuming a 1 m^2 piston face here; therefore,
numerically, pressure is force and displacement is volume), or

(101350 Pa * 17 m) * (log 17 - log 0.05678)
= 9.824 MJ

but this is a trifle optimistic because of the aforementioned cooling of
the air, which I'm not sure how to calculate properly.

Just to be silly, if one takes that 15 gallons of 300 bar
air (at 20 C or 293 K), one gets a mass of (PV/RT)
= (101325 * 300 Pascal) * (0.05678 m^3) / (8.314472 J/mol K * 293 K)
= 708 mols or 20.5 kg (at 0.029 kg/mol). Liquefy that, and one gets
25 liters or 6.6 gallons of liquid air (assuming 0.8 kg/liter). This
suggests a relatively easy way to fill up that tank but there is
the issue that one still has to boil the air somehow; ambient air,
even on a hot summer day, can only carry so much heat in per hour.

It's really a neat trick.

Still I think the external combustion engine does about the same
thing. A steam gasoline hybrid can also do over 1000 km on a liter.
But neither as as light as an empty tank. o_O

He could add a rotary engine in stead of that piston crap. lol

I was thinking/guessing.... letting air out of it the compressed air
tank will cool the tank. So, the compressed air will be really cold
when it goes into the heater?

ya, that's very hip tech.

Not as good as my car design but hey, it's being produced, that seems
to be the miracle here.

Just compare the MDI air car to a similar weight gasoline car using
the same units... KWhr per mile and $$ per mile. I think we can assume
the KWhr per mile for similar size and weight cars will be the same,
so the comparison is based on fuel cost. The compressor that fills up
that carbon fiber tank to 300 bar probably uses 10hp for several
minutes... And the biggest waste is all the energy wasted heating up
that compressed air that just floats off into space. As the air in the
tank is used, the pressure drops, and the tank gets colder, reducing
the pressure and the efficiency even more.

If the exhaust is thermally coupled back to the car --

that even takes advantage of this cooldown, feeding the
cold exhaust through a heat exchanger.

Still not all that useful as an actual power source, of course.

Compressed air powered cars are routinely used in japanies mines.
Yes, a heater can increase efficiency, although it is surprising that
it would be that much. In discussion of using compressed gas
as a back-up storage of energy, I have seen numbers of 40% overal
efficiency improvement for compressed gas / natural gas heater combo
feed into a turbine.
I think these are not real numbers but estimates done on a napkin,
and not a very clean one.

Anyway, if you consider the price of compressed gas (much more expensive
than gasoline), the combo is not economical in comparison with gasoline
alone.
You should calculate not MPG but MP$, and you will see that it is not
as impressive.

You somewhat misunderstand the spec here:
http://www.theaircar.com/onecatsEN.html

When they say in Europe gas consumption in Liter, that means per 100 km.
So 1.5 L / 100 km, and so for another 700 km they will use
10.5 L.
It is still a great efficiency, but it is also a very little car.

Actually I find more impressive that they will be able to go 100km on
pressured air alone. Of cause this is a projection using some
futuristic ultra light / ultra high pressure gas tanks.

Their actual taxi prototype using normal (but rather above
average quality) steel tanks that you can buy with 200 liter / 200 bar
(~3000 psi) pressure only went 7.22 km.
In fact it is a hilarious example of power-point engineering how they
extrapolate from 7.22 km to 214 km they are planing to get:
http://www.theaircar.com/tests.html

Anyway, how much does it cost to recharge their existing tank,
that gets them to go 7.22 km (or, after all the improvements except
the tank change, using their own factor, to 55 km)?

Lets take an actually existing state of the art, suited to the task
compressor used to refill scuba-diving tanks.
http://www.deep-six.com/page21.htm
MaxAir 55 Standard can charge 80 cu ft to 3000 psi in 12 min.
So we have:
time = 12 min = 0.2hrs
power = 20.8A * 220V = 4.576kW
energy = 0.915 kWh

80 cu ft of uncompressed air that this cylinder holds, corresponds to
28.33 x 80 = 2266 liter

But 200 liter (compressed) / 200 bar cylinder corresponds to
197 times atmospheric pressure, so to convert to uncompressed air
V = 200 *197 = 39400 liter.

Which means, it is the same as 17.4 scuba tanks (Oh, btw
it will take it 12*17.4 = 208 minutes, or ~3 hrs to pump).

So our energy to pump it is 0.915 kWh * 17.4 = 15.92 kWh
Considering price per kWh of $0.1 that I pay,
it costs me $1.6.
And, let't remember, present prototype will drive me only to 7.22km
(4.5 miles) which is damn expensive.
Assuming $3/gallon gas prices, it converts to efficiency of 8.4 miles /
gallon. That sucks!

Now, we will be generous and assume that all the futuristic improvements
outlined by authors will work out and it will take me to 55km (34 miles)
on the same amount of pressurized air. That is much better, it
gives me equivalent of 63 miles / gallon.

But with a very small car (and only in the distant future
after uncertain improvements)! You already can get that same efficiency
with a normal gas motor with a similarly small car (Smart, or Honda
Insight).

Funny how things have a way to turn out not as exciting once you start
to crunch the numbers...
I wonder if Tata motors guys did this calculation...

Much better comments this time around...

> You're saying it violates the 2nd law:

2nd law. It applies it!

Think of it this way. We have compressed air (at some useful
pressure) and at room temperature. The cooling effect (noted above)
doesn't occur until the gas expands, which is hopefully in the
cylinder creating mechanical energy.

Now what happens IF you add a modest amount of heat (from any source)
to the gas just BEFORE it enters the cylinder? Let's say the heat you
add is just enough so that the expanded exhaust comes out at exactly
room temperature. In that case, you get the energy from the
compressed gas but you ALSO get ALL of the energy from the heat you
added (minus mechanical and other losses). This is no magical
machine, but it CAN use heat below the temperature of ignition which
is MOST of the heat from burning fuel external OR internal.

But let's say you got that extra heat from your shower drain. All of
a sudden the "wasted" heat from your shower is converted into
mechanical force. that does NOT violate the 2nd law of
thermodynamics. It applies it.

Ah... but they WEREN"T after efficiency per se. They were just trying
to make the damn things work at all. And when something worked at
all, they focused on it.

And they DID apply the concepts of an external combustion engine. It
was called a steam engine and worked quite well. It's just that
taking water to a vapor required they operate at higher temperatures
and pressures. To bad every one got distracted by Otto. We might
have very different cars today.

The difference with MDI is that they can operated at a much wider
range of temperatures and pressures and they ARE after efficiency. I
don't know if this will work as they say, but I DO see reasons to
consider it.

> They're not proposing ceramic cylinders or fancy fuels, or even new science.

True. This is the "Otto" distraction I spoke of where the objective
is higher octane and temperature. That is exactly my point. What
happens when we start thinking about extracting energy BELOW the
temperature of combustion? I think it's worth investigating.
Apparently, they do too unless this is just some elaborate investment
scheme.

> Just bog standard expansion of hot gasses and bog standard compressed

EXACTLY! But this external combustion IS being applied in a way never
done before. At least to my knowledge. And that's exciting.

> When they say in Europe gas consumption in Liter, that means per 100 km.

The unit in the spec says Liters, not Liters per 100 Km, but I believe
you are correct both because of convention and it makes more sense for
a 900 lb car. I would have expected no more than a tripling of
efficiency. This means the mileage from the fuel component would be
157 MPG instead 1100 MPG. I will correct the error immediately.
Thank you.

> It is still a great efficiency, but it is also a very little car.

True. But then we should be able to get about 100 MPG for internal
combustion if the car stays under 1000 lbs. That's what the X-Prize
is all about. Time will tell.

I think it's potentially QUITE exciting. My blog post was NOT about
the car as noted by the title. It's about taking a fresh look at
EXTERNAL combustion engines for all kinds of uses.

We need to think OUTSIDE the cylinder.

Thanks for the useful feedback, Evgnij.

Which would also suggest that air at 4500psi being rapidly decompressed will
freeze the motor if you don't add some heat from somewhere?

Good observation. I now suspect this engine BECAME external
combustion as a defensive move, which would make the extended range
simply a very positive side effect.

I guess the need for cooling was the mother of this invention.

You don't get both. If the expanded compressed gas is colder, it won't
be able to expand as far, and won't be able to produce as much
mechanical energy.

You would have to heat it up just to recover all the compressed air
energy. That heating could be done free using ambient air after its
cooled, or could be done at cost by burning fuel before it cools. If
you do it the free way you can approach 100% efficiency, but that's
nothing special, a clockwork motor can approach 100% efficiency too.
Something special would be approaching 100% efficiency of a heat
engine, not a mechanically powered engine.

There are many people looking at many different kinds of engines for
many different uses. There are solar powered mechanical engines. There
are electric generators which use the wasted high-temperature heat
from gas water heaters. There is even an engine which can operate on
the heat from the palm of your hand! The more you see the less

The funny thing about compressed air..
is it works in a car under 1 ton.
The volume is square the mass of the car.
The size of the air can grows faster then the size of the car.
At 2 tons the car neads a can as big as it is .
At 3 tons the car neads a can twice as big as the car.

Put that air in a piston engine and you wount get past the door.

This is my first slide vane engine.
Sliding vane engine whale 4.

whale 6 is the 24 inch slide vane rotor with inner cam and valve spring
to hold the vanes in the rotor flush.

whale 7 is lpe whale 6 is steam whale 4 is air engine .

whales 1 2 3 dont have rotors.
they are water rockets // liquid pistons .
The steam pushes the water out of the cylinder as a stroke ,,like a jet

1 is air 2 is steam and 3 is O² boosted steam.

The o² boost it reused in the burner.

h²0 into seperate containors.

it turns out that the emf method is better when i use the steam from a
vaccume wile i add a bit of heat so it dont freeze the water.

Once its vapoure the tv set removes an electron as the gasses re pumped
off the botom and top of an acumulator tank.
The emf seperation due electron bond of h²o is 10,000 times easyer as
a vacume gas.
Put steam under presure the method dont work easy.
Put the hydraelectroliis under presure it dont work at all.
Put the electrolisis in the vacume steam and it takes less volts to make
10 times as much seperate.

big tv set has elctron gun and a cathode at the other end of the big

the chamber isfull of steam vacume from flash steam water.

the hydraelectrolis is the same thing but the TV set is 40 watts and is
one nice electron gun.
point the tv set up ...chamber the screen so gas can flow onto the face
of the screen .
pull vacume threw screen chamber from top and bottom with H colection
vacume tube on the screen and the O colection tube 4 inches above the
screen.
The steam from vacume is allmost plazma .
the emf from the screens static charge dont have to pull as hard with

But you're applying your analysis to only 1/2 of the cycle. If you size
your air-heater just right, you can get the exhaust air to be right at
'ambient' temperature, that is true. But the other 1/2 of the cycle took
place in taking in the ambient air to a compressor and compressing it. As
it was compressed, it got pretty hot and air *coolers* were used to keep the
temperature in a range that wouldn't damage the compressor or other
components.

So from a thermodynamic heat-engine aspect, you have to account for that
heat that was rejected in the air coolers. The total heat in is from your
air-heater, the total work in (i.e. 'pumping power') is from the compressor
and the total heat out (if you get your exhaust temperature just right) is
at the inter- and after-coolers of the compressor and finally total work out
is air-motor shaft power.

daestrom
P.S. If you run your air-heater at higher power, you start to exhaust hot
air and have another loss.

The air compressor is the idiots part.
It takes too much energy to compress air.
10 % of that energy to make steam in a doble boiler.
Then recycled steam lets you haul less water and more fuel and less

It should work, though perhaps not to the point of ever achieving 1100

for filling that tank of compressed N2/O2).

Why not a tank of compressed O2? (because what good is compressed

The most complex element in this engine is a pair of

the website has a picture, suggesting a somewhat working

Of what you're talking about is essentially an efficient one cycle
internal combustion engine.

Imagine what burning h2o2 plus a little of whatever fossil/synfuel
will accomplish in a one cycle combustion process, except with such
having contributed the absolute minimal CO2 and zero NOx per passenger
mile. 200 empg of fossil/synfuel shouldn't be any problem for the GM
Volt (at 5 passengers, that's 1000 pmpg).

The slide vane engine is no sterling .

4 cylinders 40 inch tall 4 inch wide .

each has a flap that lets water in the side and a flap at the bottom to
let water out like reed valves. 4 inch flaps.
The water flows in and fills the cylinder ..
650 psi steam 1/10 of the top of the cylinder full of steam ,,steeam
valve shuts.
The water is pushed out the bottom.
............. The water from the cylinders runs into the tank bottom
and the water level rise compresses the air in the top of the tank like
a spring . The tanks water runs a slide vane rotor .
The slide vane rotor is 10 % the steam volume of a piston steam engine
or your car.

10 % the steam is 1200 cubic inch second .
a V8 350 ci is 13000 cubic inch power stroke per second. A 400 ci steam
engine is 12000 cubic inch steam per second at 650 psi.
2 inch of vane out of a 24 inch rotor with 650 psi is 500 rpm 1200
cubic inch second.
1300 foot pounds tourk.

if your going to google for a liquid piston ..look at water-rockets .

Liquid postons are water rockets when used without a rotor .

The bottom flap is gone and a jet is in place .
The side intake flap lets water fill the cylinder .
Steam pushes the water out of the cylinder .
The water comes out the jet .

The adavntage is the fact the steam was not conveted from thrust to
rotoation and back to mechanical thrust . No conversion no loss.
The potenual enegy was not converted .

turbing a piston steam eng then it would have waisted 40 % of the stroke
and 60 % would be converted to rotation with a crank and then the
propeller would convert the rotatin back into thrust. With a large
energy loss each time it converted the energy.
Another adavntage is ,,there is no piston no crank , its cheep to biuld
and cheepest to run.
and above all i can get 10 times the power in the engineroom and use
1/22 the fuel.

Well, Life creatures seem to disagree with this concept.
In all living cells energy conversion usually looks like this

1) chemical reactions (of many different kinds) create proton gradient
across the membrane
2) enzyme (say engine 1) transfers energy of the gradient of H+ to
energy of creation of ATP molecule from ADP.
3) Energy of ATP to ADP conversion is used to power all other things.


There are exceptions from it, for example "motor" enzyme that turns the
shaft that move the bacteria around (Flagella), is powered directly by
the proton gradient.
But even than, it is a two-step energy conversion.

So it this multi-step step chain created by evolution because it does
not like the cell to be efficient?

I say, no, it is because the alternative was even less efficient.

There is always a compromise between robustness of the design
and its efficiency. When some part fails, it needs to be replaced,
which also costs energy. So overall energy balance (that evolution
optimizes) has to consider both momentary efficiency and robustness.

I've studied every link you gave me T.J., many times over,
and never have I seen mention of a pistonless car or ship
propelled by external combustion, steam, or compressed air.

Tata's MiniCAT will use pistons ( if it ever gets produced ).

You claim pistonless rotary engines aren't used
due to nationalism and racism, but I highly doubt it.
Mazda's internal combustion rotary engine is pistonless.

James Cooke, 1787, was Irish, not Polish.
Here's a drawing of his “ Rotary Engine ”:
www.DSelf.DSL.PipeX.COM/Museum/Power/RotaryEngines/Cooke1A.GIF

Quoting Douglas Self:

“ This engine, with its interesting semi-circular format,
is the earliest rotary steam engine known,
apart from those of Watt [ above ]. Patented by James Cooke in 1787.

[ in Cooke1A.GIF, above ] b is the steam inlet from the boiler,
and a is the exhaust to the condenser.

As the wheel rotates the flaps c fall forward by
gravity and are then kept in place by the steam pressure pushing
the wheel round. The connecting rod d is driven by a crank on the
engine axle and works the condenser air-pump.

The wheel is only enclosed up to the line f,
and one can only guess what sealing system was planned
to keep the long line contacts steam-tight.

Elijah Galloway says:
‘ The construction of this machine, we need hardly say,
► would be impractical. ’; and one can hardly disagree.

The original drawing and description are found in
‘ Transactions of The Royal Irish Academy ’ for 1787.

From The History and Progress of the Steam Engine
by Elijah Galloway & Luke Hebert, London 1830. ”.

hurt.
Its against the law .

Thats a 10 hp 240 cfm air motor off the shelf for $ 2000 but they are
very crude.

thats a 10 hp 240 cfm sv air motor.

10 cid gas engine 10 HP at 5000 rpm.
4 stroke so call it 1 fire per 2 rpm.
1000 X 10 cid ....10,000 ci pm. ,,is 820 cubic inch second.

But a 1 inch vane 24 inch rotor at 500 rpm is 71 hp and is 1200 cubic
inch second.

10hp 820 cis // vrs// 7.1 HP 120 cubic inch second.

There is so little math that goes into making cars, that most
have one or more onboard computers today.
That's because 70% of what appears to be math is just
Political Conventions. And 90% of the rest is robots.

Standard Oil has nothing to do with today's Brazil, for example.
What's stopping Brazil from selling cars with pistonless steam engines ?

By “ engine ”, I mean “ the main power plant of a car ”,
not the car's air conditioner.
