MDI's air engine technology tested on Tata Motors vehicles

In January 2007, Tata Motors and Motor Development International
(Luxembourg) signed a licence agreement that enables Tata Motors to produce
and sell compressed air cars using MDI technology in India. The agreement
covered two phases of activity encompassing the technology transfer and
proof of the technical concept in the first phase, and in the second phase
completing detailed development of the compressed air engine into specific
vehicle and stationary applications.

The first phase of this programme - proof of the technical concept in Tata
Motors vehicles - has now been successfully completed with the compressed
air engine concept having been demonstrated in two Tata Motors vehicles.

In the second phase of the development, the two companies are working
together to complete detailed development of the technology and required
technical processes to industrialise a market ready product application over
the coming years.

Odd. Didn't you post the same BS around 10 years ago only with the
plants in S America or Mexico?

Do you take stupid pills every morning?

You are a senile idiot.

Five and a half years and still diddly squat.

The press realease was this month!!!!!!

Tata are assessing the manufacturing side now having assessed the engines as
suitable.

So for those who said it would not work.,,it does.

Let's see if I've got this straight. The MDI Aircar, which "News" told
us some ten years ago was ready for the consumer market and would be
filling our streets shortly, has now been in Tata's hands since 2007.
In that time, MDI managed to "successfully completed with the compressed
air engine concept having been demonstrated in two Tata Motors vehicles. "

Now Tata might have a market-ready product "over the coming years".

Tell us again News, what's changed over the last ten years? Sounds like
the same old BS to me. They are still testing and still working to
"complete detailed development". There is still no Aircar for sale, and
no Aircar has ever been subjected to third-party testing.

Bah! Go back to sleep News.

Have you tried directing that question at Tatra who have assessed the car
and say it works?
They are still testing

Tatra stated they have done that and are now into the manufacturing
assessment stage. Read it again.

Seems like a petrol powered car with a pre-compressed air supply from the
wiki article

"A French company, MDI, has designed and has running models of a
petro-air"
"hybrid engine car. The system does not use air motors to drive the"
"vehicle, being directly driven by a hybrid engine."
"The engine uses a mixture of compressed air and gasoline injected into
the
cylinders."

All those on here say the car can't move.

Near as I can tell this is not a compressed air car,per se. It is a
hybrid that maximizes efficiency, possibly through regenerative braking.

Yes that appears what it is doing. It can run 100% on compressed air as
well, all using the same engine.
More interesting to me, which I stumbled upon while reading the above are
super capacitors:

http://en.wikipedia.org/wiki/Supercapacitors

Some companies are stating they have cracked the energy density in that fro
the same size package as a battery it hold the same energy, but charges and
discharges at an instant rate. If that is the case then see major
improvements to petro-electric hybrids, electric trains and elevators.

Air is free, but supercapacitors will outlast a car.

Yep, driven by an IC engine full time and only uses a bit of stored
energy for ower boosts as needed.

Doesn't even come close to News' pipe dream of an "air car".

Senile person, I only report what is happening.

Why lie? We have been telling you for 10 years that "It willwork" but
it is not a practical over the road vehicle due to energy density"

Have you told Tata this? They need to know as they are going to make a shit
load of these cars.
My prediction is it will flop

Have you told that auto giant Tata this? They need to know

Dunno if any of you folks are old enough to remember the "Li'l Abner"
comic strip, but there was one character named General Bullmoose who
was the archtypical predatory, big-business tycoon.

A Japanese inventor showed up at General Bullmoose's oil company
office with a self-powered compact car. A strap around the driver's
chest was stretched and relaxed as he breathed, which provided power
to the wheels. The other executives were terrified that demand for
their oil was about to drop to nothing.

General Bullmoose picked up the phone and said "Send up Miss 'Wowie'
Wong from our Asian department." An incredibly curvaceous Asian woman
strutted in at which point the Japanese inventor started panting
uncontrollably. His 'breath powered' car suddenly burned rubber and
went right through the window, crashing to the pavement thirty stories
below.

General Bullmoose sat back, lighted a cigar and said "Another business
problem solved."

Great story Diogenes. Not far from the truth.

Look under Disadvantages:
http://en.wikipedia.org/wiki/Electric_double-layer_capacitor

One decent 2500mA-Hr AA NiMH has the same current storage capacity as
9,000 Farads of supercapacitor.

http://en.wikipedia.org/wiki/Capacitance
A 1 Farad supercapacitor discharges by 1 Volt while supplying 1 Amp
for 1 Second. The battery will nominally deliver 1A at 1.2V for 2.5
<HOURS>.

They are valuable only if they can match the size, weight and volume
efficiency of Lithiums at a much lower price.

They are right-at-the-edge of being practical for
the "peak shaving", so to speak, uses. For example,
when you're decelerating your car via motor-generator,
you're producing way too much power for transfer
into a battery. But if you could dump that electricity
over to a supercap, and then slowly feed it to
the battery, it almost works.

I'm not sure if they are close there yet. But the power density is very
high, and for regenerative braking, or for quick burst of acceleration
that is very valuable.

This is your thread News. You started the discussion. Are you serious
about discussing this or are you just trolling again?
Have you tried directing that question at Tatra who have assessed the

assessment stage. Read it again.

No, you read it again. it's you who snipped the quote which was that
Tata plans to: "complete detailed development of the technology" Their
words, not mine.
