Why electricity?:
Since the day electricity is
started to be in use studies to have the advantages of electricity in more
mobile forms.
To make
something moving, to make movement continiousi to change the speed of the
movement as acceleration or deceleration, to heat, to cool, to enlighten etc. Energy
is needed. Or in an other way to change the condition of anything we need
energy.
As the
energy is not something we can hold or see; we use the energy of certain
materials by changing the form with a more useable carrier for us. For example
coal itself does not mean anything alone. We need to burn coal and exchange the
energy released to steam or air. Then the energy in the coal can be used by us.
We can move things by steam power or heat up a place or something with the
energy released by burning coal. Despite all the technology we have humanity still
can not use the energy hidden in the sources directly. We cannot use the
chemical energy in coal without burning it. Even with the nuclear sources
energy is first transferred to water to produce steam power which we know how
to use.
The
usage end the distribution of energy in such ways is neither economical nor
practical. The audiences living in a coal heated building might have seen how
difficult to transport and store the coal in these amounts. In detached houses a room or an equal sized
place is for the coal to be used. Also the ignition processes and the control
of fire is much more difficult in solid fuel usage.
After living these disadvantages
using gas heating would be seen as much beter since a small pipe is enough to
do the same work of coal. How ever gas pipes are very difficult and expensive
to install. Also energy obtaining from gas fuels needs a very tight
organisation. A small problem in a huge system can make all of the users shiver
from cold.
Also making a mobile system with
these kinds of energy sources has many problems. By the way storage and control
mechanisms are the biggest problems and are not to be solved easily.
On the other hand things to be
done are very limited in these kinds of energy sources. Locomotives can be
moved by steam power. The system to use and convert the energy is possible in
that kind of machinery. Also it is much easier to build storage rooms in such
systems. However it is impractical to make a tv or cell phone. Electronics is
basically a set of 1 and 0s to mention there is electricity (1) or no
electricity (0). This can be made by steam as steamtronic by saying there is
steam (1) or no steam (0). How ever water steam is much heavier and bigger than
almost weightless electron.
I think a steamtronic cell phone
would be as big as a 72 cm crt screen tv. And such heavy. İn order to make that
cell phone working we might have needed a coal bunch weighing about 30 kgs and
a water-steam tank as big as that. Despite all that weight is just for one day
charge. Totally impractical.
Waking up at night and putting
coal to your phone several times to make it running is another disadvantage. Forgeting
the cap of the burning place open when you are sleepy and putting your house on
fire is another caricaturised disadvantage of that kind of a system.
Transporting and using energy in
the form of electricity is much more unique. Electricity is the motion of electrons
which have practically no weight. Since electrons
are so small and can move almost witha a speed almost equal to light speed; it
is possible an deven so easy to carry huge amounts of energy in small volumes
and relatively cheaper installations.
For example a pipe carrying
natural gas to a million populated city is big enough for a transit pass with a
truck through the pipe. However the lines to carry the same amount f
electricity consists of just 3 cables as thick as an arm of an adult each. Both
producing and installing these cables is much cheaper and much easier. Just the
comparison of the thickness of the gas pipes in your house and the thicness of
the electric wires is enough to understand the difference. Also gas pipe
operates only e few appliances. However the number of the electric operaed
devices is much more.
This condition of beeing that
smaller we can carry computer technologies
enough to go to moon in our pockets and the source to power them is less than
100 grams.
Since electronic gave us the
chance to micronise technology we could want our civilisation to be with us all
day. Electric lighting at home or in the street is good but carrying a torch
with me would be beter. The big phe device was fine to use but ı want one in my
pocket. We could wish these and wish more because we have electricity and
electricity is yet the best option to have mobile systems.
Mobile electricity is not just
for luxury. Listening to music in a picnic or using chargeable vacuum cleaners
when there is wall outlet can be considered as luxury (that ı think they are
not) but still portable electric sources are needed.
It is both not economic and
impractical to install power grid to every part of the world. Even mobility can be needed in places with
power grid. As an example toys having a wall outlet cord or clocks with poer
cords are completely useles.
On the other hand researcers
working on uninhabited lands, military actions happening on open grounds or
even nature sports make us demanding mobile electricity. It is mostly neither
impractical not unnecessary to install a grid in these conditions. Maybe sometimes
impossible.
As another example the machinery
having self electricity producing capabilities like motorvehicles even need
mobile electricity. These systems are never nonstop working devices. This means
you need to give an first start mechanism. As told before electricity is the
most logical way to give that kind of starting power. However it is generally impractical
and mostli impossible to find a proper wall outlet to ignite your car anytime
you need. A mobile system is inevitable in most conditions.
As a summary electricity is the
easiest and cheapest way to carry energy. Also the possiblities of
micronisation capabilities make electricity more inevitable. I can easily say
that energy is the real value and electricity is and will be the currency of
energy for a long time. Because of that why is electricity other than the other
powering methods.
