truth, because already hydrogen drives could
represent the maintainable and ecological
concept. At last motor show in Frankfurt Hyundai showed the hydrogen ix35. This big
SUV looks at first sight as each other car,
only after starting there is no typical sound of
combustion engine. Pure hydrogen is „tanked up“ to the car which then through the
fuel element makes electricity. That charges
the battery which keeps the standard automobile electromotor. Hyundai plans to make
thousand pieces of hydrogen-electric ix35 to
the year 2015 and after 2015 to 10 times
more. Just at that time the price of automobile
should get to the acceptable levels. With the
similar hydrogen drive we met also by the car
makers Honda, General Motors, Daimler and
also BMW, which introduced BMW Hydrogen
7 in the framework of project BMW Clean
Energy few years ago. The older generation
of saloon car class 7 was equipped by engine
which was able to work also with hydrogen
which was making electric energy. However,
today the development of this technology is
not very assumed, the future is the sub-brand
BMW-i and its electric engines.
Hydrogen as the basis for the field production of electric energy is however not the
typical concept of the hydrogen drive. As it
was written that electromotors did not overshadow hydrogen, because that can be their
part, now it will not apply. Pure hydrogen drive is today almost passé. It is not acceptable
even for the car makers and nor the customers
to have high-pressure vessels with liquid hydrogen overcooled on -253°C with an explosive
potential in car. Hydrogen drive is based on
Technologies in motorism
not very complicated concept which
produces the water
vapour as emissions.
Thanks to that it is
ecological
entirely
clean.
Drive by the air
from Citroën
„What did that
Citroën introduce in
Frankurt? Car on air?
Unbelievable!“ say
the experts and lay
observers too. The
second prototype of drive Hybrid Air waited to
see a beautiful marketing and public perceives
it as „something what is able to drive on air“.
However, this is not truth, even though the air
plays an important role in the whole process
of drive.
Prototype of automobile Citroën Cactus
with drive Hybrid Air is equipped by economic
3-cylinder engine and air tanks. Those are the
storage of condensed air which gets in them
by sucking with the use of recuperated energy. When there is sufficient pressure in the air
tank, it can help the combustion engine and
so lower its energetic demandingness. That
means, the energy obtained during drive on
combustion engine changes to pressure which
is able to shift the automobile a bit further or
a bit faster. With this help the fuel, amount of
emission and of course also financial budget
of driver are saved.
Eco-effectivity at the expense of
emotion
How does the future of automobile drive
look like? It is not even today, at time of top
technologies, obvious at all. With a big probability the commerce automobile industry will
change the orientation to electric engines in
the course of the nearest decades, but development in the field of supplying an energy
for this engines will proceed also in the future.
Hydrogen, compressed air, maximum effective recuperation, these all is only a fraction of
that, what still not quite a clear future offers
to us. What can we however assume with the
big certainty is gradual fadeaway of today so
popular combustion engines or their shift to
marginal position. Do we live the last decades
of honest strong noisy automobiles?
