Next year in October 2008, it will be 100 years since
first Model T Ford car came off the world’s first production line. There
have been few serious challenges to the dominance of the petrol-driven
motor car, until now.
As petrol prices increase around the world people
are looking for new, cost-effective energy sources. In France inventor
Guy Nègre is in the final stages of testing a car that offers a way out
of our current dependence on petrol and literally opens the road to
fully sustainable transport. The engine itself runs on nothing but pure
compressed air, the very air we breathe. The primary energy source used
to make the compressed air can be any fuel derived from solar energy.
Because Nègre’s thermodynamic cycle is so efficient, the whole
power unit, including the engine uses very little fuel. It also burns it
at relatively low temperature in a very clean way.
In 1987 Nègre stopped designing Formula One
engines and decided to create a car to combat pollution. It is estimated
that a shocking 60 percent of harmful emissions in urban areas are from
motor vehicles. The idea behind the new car was to get rid of the highly
inefficient fossil fuel combustion within internal combustion engines –
because it is that type of combustion that creates pollution.
Nègre’s company is based on the Côte d’Azur near Nice. He has called it
MDI, which has as its logo a flower - the daisy. This no
“bunny-hugging”, little backyard operation that will disappear into
oblivion. MDI is already worth hundreds of millions of dollars. Within
the next few years there will be plants all over the world producing
cars bearing the daisy logo. Guy knows that he has a ready market! Not
only is this car pollution free, but it’s also cheap.
All this may sound like a mad utopian dream, but
Nègre’s invention is generating a lot of attention. In February 2007
Tata Motors of India, the world’s 5th largest automotive manufacturer
entered into an agreement with MDI to apply the MDI technology to the
Indian market.
Together with his son Dr Cyril Nègre, an
automotive engineer, Guy Nègre worked on developing his ideas. In 1995
they gave the engine its first test run. The Nègre's suspected that
their laughter would be probably be echoed many times over by sceptics,
but they knew that this invention was worth developing. Perfecting the
engine for the air car was an all-consuming process for father and son.
The Nègre's had to design an entire car to carry
the engine. To achieve higher efficiency and keep energy consumption
down, the car had to be as light as possible. Guy Nègre simplified
everything: at 12kg the engine for the first small car is light enough
to carry in a suitcase. The electrical system consists of only one wire
and the chassis is made of aluminum.
The two-metre long tanks contain enough compressed
air to drive about 150km in an urban environment in a totally pollution
free fashion. To run at faster speeds on the open road the car can use a
wide variety of fuels (petrol, diesel, CNG, LPG, bio oils, ethanol from
sugar cane, etc.) Running costs are expected to be five to ten times
cheaper than at present. The energy efficiency is more than twice that
of internal combustion engines. It is capable of reaching over 70%
efficiency in subsequent release, unlike our current fuel driven
vehicles, often less than 10% “well-to-wheel” efficient.
The engine is designed so that on the open road
the surplus power available at the crankshaft can be used to recharge
the compressed air cylinders in the car. Alternatively the car can be
plugged into the mains at home and recharge overnight, or you will be
able to eventually pull up to compressed air stations which would be all
around town and refill in about 3 minutes.
Years of experience as a Formula One-engine
designer taught Guy to protect his creation from predatory
manufacturers. Every time he perfected a part he patented it. To ensure
that there was no possibility of sabotage or theft from large
corporations, Guy turned his back on traditional sources of financing
also. His plan was to sell a few shares in his company to private
investors. This way he managed to raise enough money to stay
independent, and yet keep the project going.
Now keep in mind that this is not a vehicle for
sports car enthusiasts. The applications of the MDI technology will be
aimed at niche markets for private transport (including the small OneCAT
3-seater urban model, the 3-seater MiniCAT, the 6-seater CityCAT — CAT
stands for Compressed Air Transport), utility services (trucks, vans,
etc.), public transport (minibuses and large buses), farm machinery,
marine applications, and light aircraft applications. Another exciting
development is the use of the same engine for power generation, in the
home, as standby generators, to power large building and shopping malls
etc. What a huge difference this will make to our environment over time!
The car hasn’t even hit the showrooms and yet MDI
has managed to sell rights to licences to more than 37 different
companies around the world, including Australia and New Zealand.
Instead of literally spending billions of dollars
on one huge manufacturing plant, licensed franchisees can build smaller,
cheaper plants, which offer regional services. It is predicted that the
factory will produce 3,000 to 7,000 cars each year, with about 70 to 90
staff; cars manufactured where you live, again reducing costs, what a
great idea.
Will the air car be on our roads to
celebrate the beginning of the next hundred years of motoring? 2008
could be an interesting year for our planet and for our survival?
