Good evening everyone is red valerio
Albertines are a physicist and therefore there
I can confirm what you already know
the temperature of the planet is
increasing its global warming
that had previously been hypothesized by the
scientists has been confirmed beyond
of any reasonable doubt is the effect
greenhouse
but I would dare to ask anyone if
be aware of what it is
the greenhouse effect
I want to show you that the greenhouse effect
we all know it today is one
nice sunny day but it’s cold
out then we imagine that this is
your car parked under the
Sun
it’s cold but you’re numb
when you enter the cockpit due
of the greenhouse effect
you will feel a nice weather nice
warm comforting what it is
success
I prove this to be the light of the
Sun
this is the cockpit you see the light
passes through the windshield
through the windows and goes inside
cabin
there the sunlight that is energy
it is transformed into another form of
energy in the heat with the difference
but that while the light has managed to
penetrate the heat inside
it manages more to escape outside and
therefore it tends to accumulate and the
temperature increases progressively
this is the small greenhouse effect
ladder
let’s take our planet here it is
I represent this way
a hemisphere but unfortunately it is worth
also for the other because of the
we are productive activities
by adding a gas
carbon dioxide above all or for i
well talking about the co2 that is taking place
a function similar to that of
windshield of the car
we imagine that carbon dioxide is
this transparent veil that now is
find
on the surface of the planet the light of the
sun manages to penetrate through the
transparent veil but the problem is that
when it is converted into heat by touching
the earth’s surface that same
heat is no longer able to escape
because it remains imprisoned this is
the planetary greenhouse effect
greenhouse is one of the effects of what
of an industrial development a bit
a bit of a foolish tale that is not
been done following a plan
but by following him we heard a model
of development that actually was
invented in the nineteenth century English yes
calls the economy linear economy
linear is a scheme in which one exists
head a beginning of this process that
and extraction from the subsoil of the
products that are needed to work i
materials and to produce the goods of
consumption in the English 800 was coal
in the twentieth century instead it is oil but
not much has changed the concept is it
same we extract from the subsoil the
matter that we need both to constitute
products both to supply energy
necessary for the transformation of the
raw materials we have a product and
this product in the end we owe it
dispose of because our concept is
that the product must be degraded
degraded to waste in kind
there is nothing similar to the refusal or
to the gap what we mistakenly
we would consider rejection and waste
food and prohibits other species
living and I want to show you that in
reality if we reflect for a moment
equa the abbreviation is the motto is to think again
we also think about our role at the
our condition
It is also true for us that we feed on
waste what we need for
survive obviously eat the food
no how long can you be without eating
without food
a few weeks without drinking a few
day but without breathing how long
you can stay
just a few minutes after that
the brain cells turn off
the air or better still the oxygen that
we use what you know
I say it and the by-product of a
process that photosynthesis
chlorophyll that carry out the plants
plants take the carbon lead ride
actually water and through one
substance that is chlorophyll use
solar energy to produce the
sugars sugars are the food
of the plant but they are also the food
of herbivorous animals than of that
plant feed and animals
carnivores who feed on those
herbivorous animals the by-product of
this process the reject the waste is
oxygen
we feed ourselves on the creation of the
plants do a reason too
we are inserted in the natural cycle e
woe if the plants did not have this
excrement the seat in a lot gas
reactive and therefore tends to combine
chemically with the products they are in
around the earth and after a few months
it would be completely subtracted
to the atmosphere so if we live if
we are here and we breathe and thanks to the
plant excrement because this
what is the use and why we must
instead, rethink the model of development
cheap because in nature what
we do not exist all that
what is used is
reinserted in the cycle
so there is not a head and a tail but
there is a circle is the circular economy
what we will consider rejection
becomes second raw material comes
said and then after another matter cycle
first third and so on raw material
umpteenth in a closed cycle that requires
only energy and does not require new
matter or new food we might think
that then if it is simple to insert the
our and our productive activities in
this scheme
in a sense, in some cases it is
if we take the glass or take the
plastic or paper us what
we do at the end of the production cycle
we use it by sending it to recycling and
turning that card into that one
aluminum that glass in another
product but you have never thought about it and
almost an accidental event
I find myself a jar what I do
I throw it but do not reuse it
it would make sense to do another but if
we take a cell phone or a computer
a television there are so many materials
precious for which you are raping the
nature for which there are real forced
in earth that extract these materials
precious for the electronics from the bowels
of the earth and we do not know what
do it because the products are not
designed to be recyclable and
this is the fault the product should
be designed in such a way that
at the end of his life he could be
dismantled and re-used trouble a
continue on this scheme many
raw materials are now running out
and also those that are not in
exhaustion still entail one
violence on the territory on the ground from
which are extracted that the earth is not
more able to endure
but then all of them
products
I want to show you that a product in
particular a device a car
and in particular the electric car
allows us to rethink ours
mobility model we have to rethink
rethink which means to renounce the
comfort of a vehicle
obviously no one would be willing
more to go on foot or on the back of a mule
it would be unthinkable but if we have one
machine because this machine must
be incompatible with the needs
environmental
we take this system you see it
this simulates the operation of a
petrol engine
hear what noise these are
the frictions that there are inside a
that serves all this because the
piston goes up and down is a way
Linear alternative must be
instead converted into the circle motion
areas of the wheel therefore means that the
wheel motor are not perfectly
compatible
instead we take the electric car
we do the same thing
feel like silent because why
a few frictions the electric motor
it rotates exactly like the tires
of the machine so you can put it in
direct drive therefore does not need
lubrication does not need to
many mechanical conversion organs of
these movements
let’s go on with the electric car
we all know and I do not suffer has not
therefore the greenhouse effect
infamous that I invoked earlier in the case
of the electric car if the production of
energy does not involve itself
carbon dioxide emissions does not have
no emission of greenhouse gases but this
it is only one aspect and it is not
not even the main aspect well I want
say another that instead a lot more
worrying
immediately for our health
especially for those who live in the big ones
urban centers
our respiratory system was
shaped by nature during the
years of the millennia centuries of the millions
of years to filter all the ones
substances that are not gaseous and that
they could accidentally arrive
inside the lungs
imagine that this is a riverbed
pulmonary if accidentally one
particle of dust is inhaled
arrives on the surface of the riverbed
pulmonary here it is but it does not make big
year remains floating on the surface
the powders that are issued instead by
internal combustion engines from engines
petrol and metal powders
they are produced by these frictions that there
I did see they are much more
dangerous are the fine powders or if
they are even thinner than that
nano nanoparticles means in physics
one billionth then means that
they are particles of the size of one
one billionth of a meter or more or less
of the same size as ours
nor to itself a grain of dust
thin comes into our lungs
look at what the alveoli do
lungs have a spongy structure
like this full of ravines la
nanoparticle enters inside
of the pulmonary bed e
unfortunately as the riverbed lo
pulmonary is in contact with flow
blood
from there it is transported in each
body district in every organ and the
What’s worrying is that in the end
of last year in a magazine
very important scientific lancet is
It was established the correlation between
the onset of diseases
neurodegenerative parkinson and alzheimer
and the concentration of fine particles
in the environment that the subject in which the
subject lived but is not over yet
here we take the case of first if
we have a braking system for the
customary machines
traditional
I’ll show you how it works
imagine we all know, on the other hand
that this almost to the spinning wheel
or the disk attached to the wheel the
braking system works like this 2
jaws tighten and lock the disk
which is integral with the wheel e
convert the energy of movement of the
machine in heat energy in heat
this is the barbarian system with which the
our cars are braking and therefore while
in the previous case
the part production of particles
metal was a side effect
unwanted its heating instead
of the brake disc is an effect
necessary because only in this
so the car slows down and then
let’s get inside the atmosphere
other metallic particles with
the aggravating that while the particles
charcoal however they have one
composition to which our organism
used because they are similar to those
of which are released from
combustion, for example, of wood
we do not have metal particles
no experience in the particles
metal are not in nature and therefore
when our lungs come into the lungs
immune system does not know how to react
it usually creates an inflammation by trying
to destroy what he believes to be
a
for ion viruses with the sole effect of
aggravate the situation because to the
end inflammation after inflammation
they are the cells of the body
to suffer and possibly to
degenerate there is another way
another world of brakes is possible
I prove it I put myself in favor and
look, I drop a ball of
plastic that is a diameter
comparable with the internal diameter of the
tube I go as you see nothing strange
falls by gravity now takes instead
another ball of metal material
that it’s metallic here is it
I demonstrate why I can lift
even a jar
this is a copper pipe there is not
no attraction yet if I do
drop the ball inside goes to the
slow motion is not magic and an effect
physical is a magnetic slowdown not
it is a slowdown due to friction and therefore
means that it is possible to brake the
motor vehicles without the need to use
the friction system and the machines
electricians also have this year i
regenerative magnetic brakes that
convert the energy of movement into
new electricity and that this
particulate is all around
we’ll show you with this last one
demonstration
here there is some dust in the jar
I acted the jar and it shows that there is
a bit of dust, then we think
that the dust is deposited e
so we can not breathe it anymore
laser
look at the laser light alone
it is visible when I do it instead
go through the jar you see
perfectly that the light becomes
visible because all the particles that
they are still present but we do not
we see reflect the laser light and
these particles on the street we have them
breathe
then the conclusion of this speech
is that the circular economy not only
it’s a possibility but it’s a necessity
and a categorical imperative and exist
already of the appliances of the
tools like the electric car that
allows you to convert this theory
practice here is the electric machine
you see it’s a moving car
powered by sunlight
in reality it is only a simulation
it would take to move a car
true a car a panel one
solar paneling as big as one
tennis court but the concept is
correct because you can use ad
example on large surfaces such as i
roofs of disused buildings like these
that we have seen here in Reggio Emilia and
the implicit one use it to do
go the electric car
because the electric car is not a habit
the electric car is the last one last
ring of the hygiene chain
energy clean production of energy
equally clean and
so what is the conclusion of this
speech is that we are already without
know it in the circular economy era
this is a revolution in place one
wind of change is rising and
a Chinese proverb says that when there is
Wind of change
there are two provisions of spirit
possible the fool raises a wall for
protect the essay begins to build
windmills
