Compressed Air Car Moves Forward

by

Rebecca Harrison

PARIS (Reuters) --- Visionary 19th century French writer Jules Verne
once described a fantastical future world where cars would run on air.

He may not have been totally wrong.

Inventor, car enthusiast and environmentalist Guy Negre has built a car
powered by compressed air and hopes it will be chuffing along roads across the
world within the next few years.

Inside Negre's car, cold air compressed in tanks to 300 times atmospheric
pressure is heated and fed into the cylinders of a piston engine.

No combustion takes place, so there is no pollution. In fact, says Negre,
the air from the exhaust pipe is cleaner than the air that goes in, thanks to
an internal filter.

The car can be refilled with air at home using an electric compressor and
Negre hopes that, one day, drivers will be able to recharge the cars in
filling stations in three minutes for as little as three dollars.

The air car, which he says will cost 6,800 euros ($6,700), looks a little
like DaimlerChrysler's easy-to-park Smart city car, with one row of seats wide
enough for three and a curved, pod-like front end.

"We needed an alternative to the gas-guzzling norm so I decided to make
one," the former Formula 1 racing engineer told Reuters at the Paris motor
show, where his toy-like run-around nestled among the latest sports cars.

TOO GOOD TO BE TRUE?

Negre, who has been working on the car for 10 years, admits it sounds too
good to be true. But he says scores of industry insiders who first scoffed at
his invention had been sidling up to his stand for a closer look.

Some point out that, although the car itself pumps out no pollutants, the
electricity needed to compress the air still comes from power stations that
spew fumes or leave behind hazardous nuclear waste.

Another big obstacle to making electric cars commercially is that, despite
decades of research, they still need refuelling far more often than
conventional petrol models. Some experts say there is no reason why the "air
car" should be any different.

"The concept of a car driven by air is not totally ridiculous," said John
Wormald at the Autopolis consultancy, adding that air-powered locomotives were
used to help dig Alpine railway tunnels to avoid pumping out toxic fumes.

"But as with all these wonderful ideas, the problem is how much energy
density can you fit into a tank," Wormald said. "The car's range will likely
be small and I can't see it taking off."

Negre says his CityCAT car runs for a maximum of around 10 hours at low
speed before it needs refuelling. He insists this is not a problem as drivers
will be able to recharge at home.

Wormald said that would be impossible for anyone without a private garage
or a space in a parking lot.

Sceptics might wonder whether the big oil firms will be keen to equip their
filling stations with a new technology that spurns petrol for air.

TOWN, NOT COUNTRY

Negre admitted that the CityCAT -- which he says has a top speed of around
110 km an hour -- will work only as a city car and agrees he will probably not
persuade motoring enthusiasts to give up their Mercedes and BMW speed machines
just yet.

"It's not a real alternative to the standard car," he said. "It's an urban
vehicle that we will market mainly as a second car, targeting mainly women who
tend to go for smaller vehicles that they use for short distances."

Wormald reckons the business model is flawed.

"The problem is that people just don't want to buy cars they can only use
to drive round towns. They might not bomb off to the country every weekend but
they like to know that they can if they want," he said.

But Negre, who describes himself as a motorist who also cares about the
state of the planet, rather than an all-out environmentalist, insists the
air-powered car is the first viable alternative to conventional petrol-powered
vehicles.

"I'm a firm believer that the car means freedom and people will not give up
freedom, no matter what it's doing to the environment," he said. "So the only
way to save the planet is to come up with a car that doesn't wreck it."

Conventional vehicles running on fossil fuels still emit a tenth of the
man-made carbon dioxide which has been blamed for abnormal climate patterns
and a host of natural disasters.

Rather than selling the cars directly, Negre's company Motor Development
International offers investors a factory package containing the machinery
needed to build the cars.

"We aim to have the first CAT on the road by mid-2003, with the first on
sale toward the end of 2004," said Negre.

He said MDI had already sold 32 of the small factories and was hoping to
swell the total to 300 in the next few years. Each factory would produce 4,000
cars a year.
"The technology is all there," Negre said. "Now all we need
is time and money to get the factories up and running."

Current Production Schedule

"June 2001: Availability of the first vehicles in South Africa is still on
stream for 2003. The commencement of the construction of the Gauteng
production facility is planned to coincide with the successful SABS commercial
homologation of the pre-series vehicles arriving from France in November 2001.

Pre-series vehicles are currently in production at the Carros plant in
France. These are being built to EC regulatory standards and form the basis of
stock to be sent to each participating region (eg. Mexico, Australia, Italy,
Spain and more) at the end of the year. Each region uses these vehicles for
regional homologation and project start-up. The second and model plant is
already under contruction adjacent to the first production facility and is due
for completion in October 2001. The model plant will be the basis for plant
design in all regions, the home of technical skills transfer and a source of
product for local sales."

Motor Development International ( 10/5/00 ) ~

We will start producing pre series in Nice France by early next year. We
plan to start production in Nice 2nd half next year and production in the U.S.
2nd half year 2002.

The prices (subject to change) are $ 13,000 for the pick up, $ 14,000 for
the Van and $ 15,000 for the taxi/passenger minivan version.

Regarding dealership: MDI has created a unique business model in the Car
industry. Instead of building a large centralized facility to manufacture
150,000 to 200,000 vehicles, we intend to build 100's of small facilities that
will produce 2,000 vehicles per shift near the point of consumption which are
the large cities as our vehicles are for urban application. These factories
will be doing their own selling direct to customers and/or via the internet.

MDI has been selling to investors a right of priority for the setting-up of
a facility to manufacture zero pollution vehicles as per MDI patents. The
right of priority is for a given territory. A population of 2.5 million people
defines a territory. For example a city of 5 million people, there will be two
facilities. The same investor can purchase the two facilities but shall always
be the subject of a separate contract for a definite territory.

The right for a specific zone costs US $ 300,000. This amount will give you
the right to hold up to 30% of equity for a specific plant. Each plant will
cost US $10 million. MDI Inc. will hold the other 70%. By the time we will
start building the plant, you will have to invest an additional US $ 2,700,000
to cover your 30% of the US $ 10 million do investment.

If you are interested, you can send you a copy of our Reservation of Zone
contract for our turnkey factories together with our business plan. For
Individual investors who are interested to participate in our project, we have
devised another investment vehicle. The minimum investment is 10 000 dollars
at 100 dollars a unit which will equal to 1/10th of 1% of each individual
plant. (Each plant will issue 100,000 units) The units will be issued to no
specific site, which will be decided based on best opportunities at the time
of the construction. Based on our estimates, for every 1/10% of 1% of one
production unit, the investment will be paid back in year 4 and thereafter a
yearly revenue stream of over US $ 7,000 representing an IRR of over 40%.

THE ZERO POLLUTION CONCEPT

After more than thirty years experience with combustion engines, the French
engineer Guy Negre has developed a concept of a totally non-polluting engine
for use in urban areas.

This invention, which uses high pressure (300 bar) compressed air to store
the energy needed for running the engine, is protected world-wide by more than
20 patents owned by MDI.

In urban areas, the engine powers a five-seat vehicle with a range of
approximately 200 km using 300 litres of compressed air (300 bar) stored in
either carbon or glass fibre tanks.

The recharge of the compressed air tanks is done by a compressor driven by
an electric motor connected to a standard electric outlet. A rapid recharge,
using a high-pressure air pump, is also possible.

The MDI patents cover not only the basic principal of the utilisation of
power generated by the release of cold compressed air into a hot air chamber,
but also the means of making it economically feasible. For this purpose, the
conventional cylinders, pistons and connecting-rods have been redesigned.
Systems for the recuperation of energy have been developed as well as a new
power transmission assembly.

To demonstrate the viability of the concept, three prototype vehicles
equipped with air, mono-energy, engines were developed. A taxi called "TOP"
(Taxi zerO Pollution), a delivery van and a pickup truck were built. In May
1998, the first road tests of these prototypes were done in Brignoles, France.
The news media have expressed a great interest in the zero pollution concept.
Since May 1998, the taxi "TOP" has been the subject of more than 35 television
programmes and several hundred newspaper and magazine articles around the
world.

The potential market for the "clean engine" concept is immense: e.g.,
vehicles such as taxis, buses, vans, delivery trucks, industrial warehouse
tractors, golf buggies, lake or canal boats and many other applications in
which fixed engines are primarily used in urban or restricted areas.

A version of the MDI engine can, in addition to air, also function with the
use of traditional fuel; petrol, diesel, natural or town gas, at very low
consumption levels. The change of source of energy is handled electronically
based on the speed of the vehicle; e.g. below 60 km/h it runs on air and at
higher speeds it runs on fuel. The compressed air tanks are recharged while
the engine is running on fuel, using a built-in mini-compressor activated by
breaking and deceleration. It is also possible to recharge the air tanks in 2
- 3 minutes at a compressed air filling station.

To manage the development process successfully, MDI has contracted its
product research and development activities to CQFD Air Solution, a company
based in Brignoles, France. Here, under the direction of Guy Negre, some 20
engineers and technicians have at their disposal the most modern equipment for
engine and vehicle development, testing and production, supported by the
latest in information technology.

Until now, the main activities of this group have been to perfect the
engine and vehicle prototypes. At the end of 1998, in parallel with vehicle
certification activities and the manufacture of the engines, a
technical-commercial team was set up, responsible for marketing the MDI
concept.

As soon as the MDI engines and vehicles are commercially viable (within 1-3
years, depending on the version) they will have a market, with very limited
competition, if any, for an estimated period of 10-15 years.

Certain manufacturers have invested heavily in electric cars - generally
recommended by public authorities as being the solution to urban air
pollution. However, electric cars are largely ignored by the public due to
high cost, limited range, long recharge time and the negative effects of
battery replacement, pollution and a difficult recycling process.

Another technique, which has consumed considerable investment, consists of
powering vehicles by fuel cells. Professionals agree, that this technique is
still far from being adapted to mass production, remains very expensive, is
heavy and complicated and uses fuels which are, in general, dangerous and
difficult to store.

When the first applications of the MDI mono-energy engine have demonstrated
the viability of the new concept, the air and fuel, bi-energy, engine will be
introduced to major car manufacturers in order to study its adaptation for
their common models. The engine will be produced by the manufacturers within
their existing structures. The engine is significantly lighter than a
traditional engine, it is less expensive to produce, maintain and utilise, it
uses and pollutes less when it runs on fuel and is totally pollution free when
it runs on air.

The different versions of MDI engines provide the most comprehensive answer
to the urban pollution problem: simple, economic and inoffensive.

The commercial strategy is currently concentrated on the urban markets,
with products including taxis, delivery vans and pickup trucks.

Based on a new concept of local vehicle production and sales, MDI promote
regional manufacturing license rights in the form of franchised turnkey
factory systems. Such a turnkey factory will have a normal production capacity
of 2,000 – 4,000 vehicles per year and will employ some 130 people. A model
factory is being constructed in Brignoles, France.

It is estimated that the first zero pollution vehicles will be on the
market in year 2000.

Mexico City Purchases Zero-Pollution Taxi
Fleet

Imagine pulling your car into a service station, driving right past the gas
pumps, and filling it up with air. That idea has come one step closer to
reality with the announcement that Mexico City has purchased a fleet of 40,000
zero-pollution taxis powered by compressed air.

The taxis, produced by Motor Development International (MDI) in Brignoles,
France, will hit the streets of Mexico City sometime in 2001. Their
two-cylinder engines, which use a combination of heated outside air and
super-compressed air stored in under-car tanks, can travel 120 miles on each
tank of air. Drivers can fill up at a gas-station air pump in less than three
minutes, although filling up at home, using a household electricity source,
takes about four hours. Remarkably, these vehicles don't stop at zero
pollution -- they actually remove pollution from the air. When a driver
brakes, the MDI vehicle takes in polluted air and filters it, expelling the
cleaned air upon acceleration.

In addition to air, a version of MDI's engine can also use traditional
fuels at very low consumption levels. The choice of energy source is handled
electronically based on the speed of the vehicle (below 60 kilometers per hour
the car runs on air, at higher speeds on fuel). MDI vehicles are expected to
be released internationally in 2000 at an average price of $13,000.

Running on Empty

by

Heather McCabe

Just when you thought the EV1 was Mother Nature's eco-dream on wheels, a
small start-up in Brignoles, France, has built an air-powered car that makes
electrics seem like noxious nightmares.

The company, CQFD Air Solution Sarl, is led by Guy Nègre, whose curriculum
vitae includes designing engines for lightweight aircraft and Formula One race
cars. Nègre came up with the aircar concept seven years ago while trying to
develop a cleaner-burning engine. To power the pistons, Nègre's two-cylinder
motor uses a combination of heated outside air and supercompressed air from
tanks stored under the car. Already, the Mexican government is planning to
purchase a fleet of 40,000 compressed-air-powered taxis.

At gas-station air pumps -- where others inflate tires -- Nègre can
fillerup in less than three minutes. A tankful lasts about 120 miles. And
since carbon filters scrub the expired air before it's released, "it produces
negative pollution," Nègre says.

So far, Nègre and his team of 20 engineers have developed three prototypes
-- a taxi (above), a van, and a pickup. The vehicles are expected to receive
international release in 2000 at an average cost of $13,000.

Technical data: 2 cylinder engine, uses heated outside air &
supercompressed air from tanks under the car, can fill up in less than 3
minutes at a gas station air pump, a tankful lasts 120 miles.

A Car with a Healthy Air

by

Paul Webster

A French engineer has invented an urban car that runs only on the air
around us. The first ZP taxi - ZP stands for zero pollution -- will be
unveiled in Provence later this month before going into mass production in
Mexico.

The inventor, Guy Negre, opened his engine laboratory at Brignoles in the
Var three years ago to perfect a motor that runs on a tankful of compressed
air. In urban road trials, his air driven engine mounted in a Citroen AX
chassis ran for 10 hours with a top speed of about 100 kmh. That is a better
performance than any electric car in production.

The Mexican version of the vehicle was designed by an Italian company and
resembles a small family saloon with a separate compartment for the driver and
four seats at the back. A Mexican licensee, Dina, has signed a contract to
produce an estimated 40,000 ZP taxis and urban delivery vehicles a year. It
hopes to replace all of Mexico City's 87,000 petrol and diesel taxis.

Mr. Negre, who worked on high-performance and Formula One engines for 30
years, runs his business, CQFD Air Solution, with his son, who is a former
Bugatti engineer, and 16 employees just off the Mediterranean motorway to
Nice.

His silent, odour-free engine design was chosen for the world's most
polluted city after a worldwide search by the Mexican authorities that
included tests on dozens of electric and other non-polluting experimental
vehicles.

"My car was the only one totally dependent on compressed air for city
running," says Mr. Negre. "Compressed air is used to start Formula One cars,
but in this case the compressed air is the fuel driving a motor with classic
components such as pistons and valves. But it is much lighter than the average
engine."

Sixteen patents have been taken out to cover an integrated system in which
300 litres of compressed air can be pumped into the tank under high pressure
in three minutes. The car can also be refuelled at home in four hours by a
small compressor in the car linked to the house electricity supply. While the
air is free, the electricity used to refuel the tank at home would cost less
than $2.

The car is being studied by other countries, including the Netherlands,
because it can also clean up air that has been polluted by petrol vehicles.

"One of the vehicles advantages is the carbon filtering system, which means
that the car sucks in the polluted surrounding air during braking and then
breathes out purified air," says Mr. Negre.

Air today, Mexico City tomorrow

Paul Webster

WITH nothing more than a slight wheeze as the compressed air tap was turned
on by the driver, followed by a polite phut-phut from its eco-friendly motor,
the bright green car that might change the way we drive in the next century
set off for a run outside the workshop in this southern French city.

Its designer, Guy Nègre, who abandoned the Formula One race circuit to
build a zero-pollution car, had reason to smile as the vehicle accelerated as
smoothly as a petrol-engined version. The demonstration was his first answer
to the scores of skeptics who reacted critically when the Guardian Weekly
first published the news in February of a compressed-air prototype that could
be filled up for a less than $2 and run for 10 hours in urban conditions.

From the pile of correspondence to the editor here is a quote from Graham F
Andrews, in Gresham, Oregon, USA, summing up the skeptics' viewpoint. "In his
writings on two cultures, C P Snow drew a parallel between liberal arts types
who did not know the Second Law of Thermodynamics and technical types who had
never read Shakespeare," he wrote. "By this standard your Paul Webster should
either go back to school or be demoted to theatre critic."

Apart from the fact that being appointed "theatre" critic should not be
considered demotion, I had to check out his theory that it would need several
thousand atmospheres to move the vehicle and that pressure would be so high
that sitting on the air tank would be like sitting on a bomb. This big bang
view is rather important as Mexico plans to mass-produce the vehicle under
licence to replace the capital's 87,000 taxis.

Preconceptions about noisy and greasy car factories take a knock on meeting
Mr. Nègre, whose workshop in this town near the Mediterranean beaches, is as
clean as a clinic. White-coated engineers build every component and chassis
part for brightly-coloured toy-like taxis that would appeal to Noddy.

Mr. Nègre is a down-to-earth, self-taught engine designer. At 58 he is
recovering from losing a fortune developing a Formula One motor that ran into
opposition from big manufacturers. For this reason he has no plans to take on
GM or Ford with a private-car version of the air-driven vehicle.

"There is no point in clashing with the big firms when there are so many
specialist slots to be filled," he said, before giving technical details of a
motor known as the MDI EV3 C that uses nothing except the air around us. "The
air tanks are a special design made in carbon and are 100 percent safe. They
contain 300 litres of air at 300 bars and can be refilled in three minutes
under high pressure. The car's maximum speed is 100 km/h, and urban autonomy,
with full tanks, is 10 hours."

Without taking the compressed air engine apart or sitting in the car for 10
hours while it runs around Mexico City, there is no reason to doubt Mr Nègre's
claims, backed up by detailed diagrams that have persuaded 160 backers in
Britain and the rest of Europe to take up shares in Motor Development
International in Luxembourg, which oversees investment.

For skeptics who want to take the argument further, Mr. Nègre hopes to hear
from them at CQFD Air Solution, Forum Aurelia, Route du Val, 83170, Brignoles,
telephone +33498-051000. E-mail: [email-masked]

by James Geary

In Brignoles, France, engineer Guy Negre has invented an engine that not
only runs on thin air, but improves air quality to boot. Negre's Zero
Pollution Urban Taxi covers about 200 Km on 300 L of compressed air, which is
stored in tanks similar to those used by scuba divers. In addition to a
combustion chamber, the Z.P. taxi has an expansion chamber that compresses air
at high temperatures. A small quantity of this compressed air is then injected
into the combustion chamber at room temperature, producing a rise in pressure
sufficient to drive the motor's cylinders. Designed specifically for inner
cities where stop-and-go traffic accounts for a significant portion of
polluting emissions, Z.P. vehicles inhale a fresh supply of air in about a
minute at specially equipped service stations or recharge in four hours at
home using a small electric compressor. The zero-pollution cars are also
fitted with a carbon filtering system that sucks in dirty air during braking.
The result: air emitted by the Z.P. engine is actually cleaner than that of
the surrounding environment.

But it may take even longer to persuade automobile manufacturers to build
it. Car companies "have a set mentality", he says. "The have already spent a
great deal of money on the electric car, which turned out be heavy and
expensive. They don't want to listen to another new idea." The Mexican
government, on the other hand, is all ears. It's backing an order for 40.000
Z.P. Taxis to replace the gasoline and diesel models in Mexico City, which
suffers from probably the worst air pollution in the world due to its high
altitude. Mexico's City first pollution-free taxis will hit the streets in two
years. while they are not yet ready to displace fossil fuels, zero-pollution
vehicles can still play an important role in reducing the level of greenhouse
gases. "If we start with taxis, then move to buses and vans, " Negre believes,
"it will take very little time to improve the pollution problem in our
cities."

Abstract ~ A method for reducing pollution in a
mono-mode air-air combustion engine having an intake and compression chamber,
connected to a constant volume expansion chamber, which is connected in turn
to an expansion and exhaust chamber. External air is drawn into the intake
chamber and compressed to an increased pressure and temperature. The
compressed air is transferred to the constant volume expansion chamber,
wherein additional, ambient temperature, compressed air is injected therein.
The injected air, when contacting the elevated pressure and temperature of the
compressed air causes an expansion of the air within the constant volume
expansion chamber. The energy associated with the air expansion is transferred
to the expansion and exhaust chamber, wherein the continued compressed air
expansion produces a work force that is imparted to a piston. The energy
depleted air is then exhausted through an exhaust value.

Abstract ~ The invention concerns a method for operating a
pollution-free engine chamber by injecting supplementary compressed air,
comprising a suction and compression chamber (1) and an expansion and exhaust
chamber (4) independent of each other, which consists in separating the
pressure increase process in said expansion chamber by dividing it into the
two chambers, an engine chamber (2A) which receives high pressure air and a
working chamber (2B) which receives the supplementary compressed air with
lower pressure, separated by a quick-operating plug (2c) which communicates
them suddenly thereby causing, owing to difference in pressure levels, a wave
expanding the engine gas which flows into the working chamber generating a
compressive shock wave substantially increasing the pressure level in the
chamber shortly before it is communicated with the expansion and exhaust
cylinder (4) to produce a work.
