well be heaven I’m happy now I would like
know something from all of you how many
steps you have taken to get here
Well, there are those who have traveled thousands of
kilometres
who even started a day ago e
who instead is yes we must say that
this lucky one had an alarm clock
this morning at 8 o’clock crossed the city
or piazza de ferrari here behind and now it is
here in front of what matters is that there
you are set out to come today
here other texs of genoa and I now there
I ask since you started up
now
how many steps have you taken
how many here I see yellows at the bottom that
both taking out the cellphone for
be amazed by the exact number of steps
frequency to kilometers traveled dress
his app just a day but it’s okay
same
what matters is that it is that number
shown on the display
it is not a simple number is energy
pure
ok is indeed the energy that you
you have employed to come here and it is
a clean and green and lasting energy
look at me are the nice ones that you
I suggest that I would call it a source of
renewable energy as you say as the
exact sun just like the sun i
Our steps are energy
we ourselves are energy, perhaps we are not
facts of the same substance as the stars
it is good and after many and many steps e
even in the many paths from my beloved
island prevent up to here
here we are, in the hall of screams, a hall a
ricadi history illuminated by those
spotlight
you can hear my voice thanks to
here you speakers and I speak to you from
this microphone but sorry for a moment
123456789
but a moment that feeds all this
instrumentation
sure if he discovered it but in this
moment we could not be so much
pleased
today, in fact, most of it
energy comes from sources
fuels or oil and coal
think to make a kilowatt hour of
energy power plants spit
in the air 410 grams of co2
of the carbon union
now as I am an engineer a little nerd
I tell you that it is a molecule of co2
it weighs so much to understand it we do together
a perfect living experiment then
we consider a solid a cube a cube
one cubic meter perfect inside
we put a bag of black sand that
it weighs about two kilos
what we just did and
build the model that represents the
density of the co2 which is equal to
1.98 kg per cubic meter guys is a fact
that your face is so scared
It seems like you’re telling me alessio but
excuse me for a moment there is an engineer for
nothing but since the co2
weighs since the air has a weight
strange, true and I tell you that only
reasoning in terms of large numbers
we can understand what the weight of the
co2 and the damage it brings to the world
that surrounds us
now I state that I do not want to be the
professor bacchettone that makes you the
Lesson on co2
we all know indeed very well as one
increase in co2 and lead to an increase
of the dissolution temperature of the
glaciers therefore stable conditions
all over the world and repercussions at the level
global
we all know this then gods
damage
acknowledge this event 13 July 2014
final of the disputed soccer World Cup
in brazil final score 1 to 0 for the
Germany counts Argentina you have it
view this game true that the view
I saw the courage on my hands
this match
a lot of people saw it in the world
over a billion viewers
witnessed this event
what however not everyone knows is that
this match led to
an emission of co2 into the atmosphere of
150,000 tons or 150 million
kg of co2
so several of those little bags of
stabia in that we just mentioned
Wow, I can not even take it easy
an hour and a half war a match that
produce co2 as well there must be one
solution to get out of this impasse
wow but stop all but we do not have
said before our steps only
power
here is the solution our steps was
right under our feet use
an alternative source unthinkable as i
our steps to produce energy
clean electric
that’s how he felt like a prometeo after that
he stole the fire from the gods to give it
we humans are the solution
but now we must understand how to find one
system that allows us therefore to
harness this clean energy then
take it out of our steps and channel it
use it for what we like best
make a floor or floor found
smart formed by tiles
intelligent that transform each of ours
step into clean energy
here is our contribution to solve
the increase in the energy needs of the
world and to reduce co2 to one
simple smart tile everything
here
now though we are in the fall
forwarded in yes a little to do
freschetto I would like to invite you put one
jacket to take a ride on mine
delorian parked water outside
led by my friend Professor Brown
and we take a journey through time up
until March 21st 2017
spring begins and is true
awakening of nature awakening of the
life
the ice melt the vegetation
returns to bloom and a warm wind of
change envelops everything and makes us
forget the cold that is coming
of you certainly understood from mine
accent what are my origins and of
this tile that produces energy e
well we both come from Sardinia
a land that has remained for most
part being wild and uncontaminated is
as you can see green and green
if you want to find me in my city that
it is right under the gulf of angels
has cagliari immediately you will make it
account for something you can admire
expanses of wind fields and panels
photovoltaic panels that produce energy
clean green energy you look at me
to say that it is in the Sardinians we have the
renewable in the blood well in this
earth kissed by the sun and by the sea where
excuse me if I tell you but it’s always
spring is too good
this clever tile arises that
represents all the desire we have
today we young people to take flight
look up and push us to the right
beyond all limits
well this spring of which I have you
just talked and in fact she is this
tile now no back engineer then
I have to give a proper name to things
so this spring is one
technology, a technology that is underneath
the tiles on which all
we walk to go to the university
to go to the post office even to eat
an ice cream here in piazza de ferrari e
every step we take thanks to her comes
turned into energy
alessio sorry for a moment but that
devilry if going to tell al
ted what arrest you what
allows a simple box of
produce dry energy
and therefore to become magical is that
physical property called
piezoelectricity piezoelectricity
electricity now who among you has done e
he is doing classical studies can to this
point to boast with the girl sitting
next I invite you to do it to know
the etymological meaning of the word
and I must say that
we speak as an engineer and I have a high school fract
classic this time the notorious greek
finally he comes to help us
piezoelectricity in fact derives from
Greek ps which means to press while
electricity electricity
we all know what no electricity is
let’s join the two words is boom we find ourselves
in 1880 the curious brothers’ workshop
pr and jack the first that studying the
quartz discover an effect
in fact, piezoelectric returns to notice it
like crushing this material that
then the quartz the first piezoelectric
of history to notice it like this
He responds to a current in accordance with
precisely energy
so here is the piezoelectricity
allows her to transform ours
steps into clean energy is nice
this clean and lasting energy
the source that generates it as now
we understand it is the most renewable
that exists on the face of this earth
and so are our steps
now you understand why I was pressing first
so much to know how many steps indicated the
your pedometer right now
let’s recap or as the Romans said
repetita iuvant
so our little tile mischino for
always call a lot in the we give it to you
a name to this tile then
represents the first true within a
elastic spring components I would say
that you hurry push is fine spring in
English means in fact both spring
that spring therefore is a perfect name
talking to our dear friend well
promoted rather baptized spring and then
our spring is a technology
totally integrable in the
traditional flooring is it
ceramic linoleum carpet or parquet and
transforms our every step into
electricity in energy by effect
piezoelectric its own structure e
friend of the environment
spring is indeed made with
recycled materials that not only
reduce the co2 hands bring down the cost
of production and therefore also the cost the
price to the final customer
spring is a low-impact technology
environmental almost nil and is precisely one
thick box a few cm 43 dimensions
of 30 x 30 cm and has a surface on the
which I fix the traditional floor
that can get lowered by 2 mm
if he walks on it and transmits it
pressure to the electric lace that stands
inside every spring step releases 2
watt of power while the energy of the
accumulated in battery
now that beautiful category as I could
could we enjoy the spring I
I personally love listening to music is
if there was a way to recharge a thousand
plots p3 without having to always stay in
home to look for the plug to attach me to
reloading would make me comfortable that to
end will benefit from you will be able to employ
the energy produced as best it believes for
example to illuminate a square for
recharge phones that are always
drains to power a wifi modem
so that you have internet throughout
our city and also to feed
these screens to give information
obviously to those passing by
push will be installed in a manner
very easy thanks to its small ones
dimensions or on the screed or directly
on the traditional floor and on it
I can put as in this case of the
ceramics in this way
let’s see spring invisible and can therefore
be installed in a square at
historical center without defacing the
landscape or change town planning
the first is below is smart respect
to others perfect spring also can
be installed then as I said
we have now understood the places a lot
crowded like a square a center
commercial an airport since more
people there are and more energy than
this magic box can come out
think with only 20 steps spring can
turn on the lamps with led lights
and if we put her in piazza de ferrari
with all the citizens who pass by
all day in the evening we could
eliminate with the same square and in
this way the municipality of genova could
have a saving on the associated costs
to lighting and also reduce co2
in a shopping center instead pushes
can open and close the doors
sliding now what comes to me from
suggest today’s high rics here to giovan
here in genova sorry, it is simply about
be aware of something then with i
your steps
you can go everywhere and every one of you
step remember well to energy
we alone turn on a light but in
thousands we can illuminate a square
a very nice thing this
now I tell you a secret there was a nice one
secret wherever mine always goes
steps
but to know how many steps are
arrived so far this is the number
now I’ll be an engineer but he manages a bit
difficult to read veil read
happy to have you knew how to do it
I think mary poppins and his cellino
are the only ones who can read the
number with a supercalifragilistic to in
half though I can not do it
so if you want to remember today
of me as the speaker of the steps of the
billions of billions of millions of passes per
I’m fine, in fact I’ll go very proud of it
one thing for me that you like you must
know the steps and I’m sure many
of you as soon as I get out of here they will start
counting steps and I already imagine myself here
walking in the road that contacts them and
14 15 16 17 18 19 and 20 ok on or off
123 shooting count
and that’s how it must be then
remember the steps the steps are what
allow a city to change the
face to give him energy the steps are the
future and now I would like to know something
from you we see if you followed me up
at this point you have observed me and
you are therefore good observers
how many steps have I done on this
appeal of the red
It puts its product by the courage I
Thank you
d hi
too good thanks
[Applause]
