Thank you and GOOD VISION!
Photovoltaics, green technology that is environmentally friendly
which saves on the much-hated bill
and allows you to produce your own energy to be introduced on the national network
to satisfy the thirst for electricity
of an increasingly digital society
a great friend when immersed in nature
our trusted cell phone decides to abandon us
a precious friend even at the frontier of ecological transport
even used on trains
that every day travel our landscapes
Well yes!
It may not seem
but photovoltaics
it was even used on the means of locomotion
and more generally in the rolling stock of RFI
Let's talk about a project
European dating back to the year 2003
which remained operational for two years
already in 2005 it was canceled
and envisaged the use of solar panels
on a locomotive
an E636
of the luggage wagons
and freight wagons
the use of photovoltaics
it was meant to keep the accumulators charged
when
for some reason
the power from the airline was missing
they could mostly be employed
when the locomotive was disconnected
to continue to keep passenger services active
in freight wagons
it was used
to ensure a source of energy
to door security systems
and to the geo-localization system
The project was canceled
because it did not give the desired results
or at least only on some rolling stock
he returned some interesting results
this because
for land compliance
most of the time
the rolling roads risked being in a shaded area
as far as a solar panel is efficient
if it does not receive direct sunlight
its performance is very poor
therefore with respect to the assumed values
only 80/90% was obtained
at least this in the carriages
the data was good
far from the locomotive, on the other hand
for the E636
and for an ALN
performance data decreased to 40%
therefore on the upper floors
they decided that it did not make sense to invest so much
in a solar project at railway level
when the rest of the country
it was still completely dependent on fossil matters
it did not make sense to convert
an entire rolling stock
composed of thousands of units
to the solar
when 90% of commuters
of a city
how can it be Milan or Rome?
they are still moving by car Euro 2 or Euro 3
What do we do?
I actually want to achieve
a fantasy interpretation
of this project
which has however the peculiarity
to have the solar system working
therefore they will be used
true solar cells
that for the physical dimensions
that they have
they can not be
used in true scale reproduction
A realistic reproduction
would see the original roof left
covered with solar cells
Solar cells
that can be purchased by a private individual
the smallest ones are 53x30mm
and are rectangular in shape
they can not follow the curved shape of the roof
therefore I have chosen
to take the roof of the Gran Comfort carriage
of the Roco
dig it completely into the central part
and place cells there
Obviously this leads to a loss of realism
because we find ourselves having a flat roof
in reality the roof was always round
however, I repeat that it is a fantasy interpretation
and so I am free to do it
I hate to say it
but unfortunately the first parts of this video
where I showed the works that were done
at least at the level of the original roof
they were lost
so I can only show you
what is the final result
The work done is
on the roof that has been excavated
and on the carriage
the removal of the original roof sealing pins
The carriage has become completely smooth
the protrusions are no longer there
it is possible to see the removal of the material
and at a later time
this part will be included in the video
the various transversal parts will be eliminated
as they are located right where the LED strip will go
The system will provide 4 solar cells
from 5 volts each
capable of delivering 20/30 mA
then connected in parallel with each other
to feed a 5v led strip
all this will be shown in the video
so I invite you to continue the vision
and now let's start with the work
as mentioned previously
the first part of the video was lost
however in this piece
it is possible to see
cleaning work
that was done later
roof milling
after routing the roof
we started to rebuild it with some plasticard
we cut out the plasticard
to make shapes
that could be put
as closing at the original ends of the roof
as a closure to eliminate the open space
of this operation the most complicated part
it was the dimensioning of these bulkheads of the correct size
work performed with the use of glass paper
we then glued
these rods at the end of the original roof
to give it a structural continuity
it was then resized
the central base of the roof
in such a way that it matches perfectly with both ends
Finally to get an idea of the space occupied
we tried to place the cells on the roof
in different positions
and without the protective plastic
which impaired its real size
Once done this
we have to prepare the bottom of the cells
it starts by removing the adhesive covering the contacts
once removed, the metal contact is removed
the use of a welder is recommended
and an aspired pond
in such a way as to remove excess tin
with the aid of a glass paper
the sides and the bottom are smoothed
in such a way as to have smooth surfaces
to level the slots as much as possible
vinyl glue was used
as it will become transparent
and it's easy to use to fill in the various cracks
It was then used of glass paper
to make the surface rough
to make sure that the color is attacked as best as possible
with a damp cloth
the residues have been removed
left by the previous operation
the surface was then dried
to allow the primer to adhere perfectly
a plastic primer was used
to allow the next painting
a better grip
to avoid that smooth surfaces did not attack the color and leave smudges
arrived at this point
we proceeded with the actual painting
through an airbrush
we painted the roof
of a graphite gray color
the color has been diluted 1: 1
to avoid smudging and give better uniformity
waiting for the roof to dry
wires were welded directly to the solar cells
these will allow
at the time of assembly
a simpler wiring
arrived at this point
the last operation to be done
it was paste the cells
the wires have been made to fit in the appropriate holes
and then all 4 were glued together
the positioning took place according to a scheme
studied previously
to allow each cell
to adapt in the best possible way
to the holes on the plate
the last operation performed
it was the removal of the plastic parts
present in the middle of the carriage
these would have prevented the housing of the led strip
arrived at the long-awaited moment
the last operation to be performed
it was welding the wires coming from the solar cells
to the contacts on the led strip
i + al +, i - al -
the cells now work in parallel
providing a greater amount of energy
And so after about a month of work
finally the project is finished
we can say that he managed fairly well
to be also the first job
where I had to rebuild a previously modified structure
Unfortunately at the expense of what I hoped
the lighting is not very high
I also had to remove some LEDs at the ends
to try and give a little more brightness to the interior ones
however with only 4 solar cells
from about 20mA each
the results are what they are
one could have opted
for the removal of the entire original roof
and then with the insertion of a fifth cell
surely it would have been brighter
but it would not have made a difference in a condition like the current one
where they are not directly exposed to the rays of a lamp or the sun
the wagon is not illuminated
this is certainly more than a plastic work
or collectibles,
it was more a style exercise
I had an idea in mind
I had in mind a particular project
and I wanted to make it happen
I would still like it
make a small change in the future
that is, the insertion of some decals made by me
I'd like to write here on the side
maybe the words "Photovoltaic Train"
this wagon unlike atriums
it was not equipped with a passing electrical conduit
the hooks are of the standard Märklin / Trix short hooks
this because
at the plastic level
in my employment, this wagon will be a shield wagon
in past videos
I showed you how
the Telex Digital hooks
with current conducting hooks
they had problems sticking to each other
this because of the slight differences
present in the current conducting hooks
this carriage will be used
between carriages equipped with conductive hooks
and a hypothetical maneuvering locomotive
at this moment the add-ons are not mounted
not even the external bellows
this because
I learned at my expense
that perform work with mounted add-ons
in fact there are only unnecessary risks of breakage
I would say that finally this video has come to an end
I hope this new form factor
with the time lapse you enjoyed it
I wanted to try to show as much as possible what I was doing
if you have any suggestions
some ideas or some curiosity
write it in the comments too
I will be happy to answer you
I greet you
and see you at a next video

Here are the thanks and the credits
therefore the rest of the video will NOT be subtitled
In the background there is evidence of recording the video
