- I often look at the news
Spesso leggo le notizie
to find problems around the world.
per conoscere i problemi nel mondo.
I heard about the Zika virus outbreak,
Ho sentito parlare dell'epidemia del virus Zika
and I wanted to use gene editing techniques
e ho voluto usare tecniche di editing genetico
to help prevent this from happening.
per evitare che accadesse.
And then I heard about Malaysian Airlines going missing.
Poi ho sentito di aerei della Malaysia Airlines scomparsi
So, I created a blackbox finder.
e ho creato uno strumento per trovare le scatole nere.
But then, I found out about Flint.
Ma poi sono venuta a conoscenza del caso Flint.
Which was one of the biggest problems I'd ever seen.
Uno dei più grandi disastri che io abbia mai visto.
My name is Gitanjali Rao. I'm a scientist and an inventor.
Mi chiamo Gitanjali Rao, sono scienziata e inventrice.

In 2014, Flint switched their water source
Nel 2014, Flint ha cambiato la propria sorgente d'acqua
from Lake Huron to the Flint River,
dal lago Huron al fiume Flint
which caused lead contamination
causando una contaminazione da piombo
in drinking water.
dell'acqua potabile.
The part that hit me the most was that there are all
Ciò che mi ha colpito di più è che ci sono
these children who don't deserve unclean water to drink.
tutti questi bambini che non meritano di dover bere acqua contaminata.
I wouldn't want that to happen to me or my family.
Non vorrei che accadesse a me o alla mia famiglia.
So, why should it happen to them?
Quindi perché deve succedere a loro?
Denver, Colorado
Denver, Colorado
I saw my parents testing for lead
Ho visto i miei genitori fare un test per rilevare piombo
and other contaminants in our drinking water,
e altri inquinanti nella nostra acqua potabile.
and it wasn't reliable or it was inconvenient.
Il test non era attendibile né comodo.
- The current test for lead could take up to two weeks.
L'attuale test per rilevare il piombo può richiedere fino a due settimane.
That is quite expensive
È piuttosto costoso
and is very laborious to get a result.
ed è molto laborioso avere un risultato.
- So, what I wanted to do was
Così ho voluto
to create a lead in water detection tool.
creare uno strumento di rilevamento del piombo nell'acqua.
I came across this new technology
Ho trovato questa nuova tecnologia
using carbon nanotube sensors
che usa sensori composti da nanotubi di carbonio
and wanted to expand the idea
e ho voluto ampliare l'idea
to detect Lead in drinking water.
per rilevare il piombo nell'acqua potabile.
In the beginning, I wasn't even sure
All'inizio non ero neanche sicura
if this idea would even work.
che l'idea avrebbe funzionato.
I needed guidance and I needed a lab.
Mi serviva aiuto e anche un laboratorio.
Denver Water Company
Quando ho conosciuto Gitanjali
- When I met Gitanjali,
ho pensato che si comportasse
I thought that she conducts herself pretty much like an adult.
come un'adulta.
She's combining the skills of an engineer, of a scientist, of a designer.
Ha competenze di ingegnere, scienziata e designer.
So, we decided to partner up with her because we have
Abbiamo quindi deciso di collaborare con lei perché abbiamo
a common goal to provide safe drinking water.
l'obiettivo comune di fornire acqua potabile sicura.
- When they offered me the lab space
Quando mi hanno messo a disposizione il laboratorio
I come home and I start screaming my head off.
mi sono messa a urlare quando sono arrivata a casa.
It's like "aaghh!" or something like that.
Ho pensato "aaahh!" o qualcosa di simile.
I was so excited.
Ero così esaltata.
I knew that if I could get this to work,
Sapevo che se fossi riuscita nel mio intento
I could help so many residents of Flint.
avrei potuto aiutare tantissimi residenti di Flint.
My device is named Tethys
Il mio dispositivo si chiama Tethys
after the Greek goddess of fresh water.
come la dea greca dell'acqua dolce.
To create Tethys, I went through a lot of different versions
Per creare Tethys ho sperimentato tante versioni diverse
and now it's a 3D printed, fully wired device.
e ora è un dispositivo completamente cablato realizzato con la stampa 3D.
In order to test for lead in the water, using Tethys,
Per rilevare la presenza di piombo nell'acqua usando Tethys
you attach a disposable lead sensor cartridge
si deve attaccare una cartuccia sensore per il piombo monouso
specially treated with chloride ions.
trattata con ioni cloruro.
If the water has lead, it sticks to the chloride ions
Se l'acqua contiene piombo, questo si attacca agli ioni cloruro
and causes resistance to the flow of current.
e oppone resistenza al flusso di corrente.
So, the more resistance, the more lead.
Quindi maggiore è la resistenza più piombo c'è.
To display the results I wanted to create an app,
Per mostrare i risultati ho voluto creare un'app.
so I used Android App Maker because that's what was easiest
Ho usato Android App Maker perché era il modo più facile
for my first time creating an app.
per creare la mia prima app.
I connected the device to the phone using Bluetooth,
Ho connesso il dispositivo al telefono tramite Bluetooth
and I could see my result of either safe,
e ho potuto vedere il risultato: acqua sicura, leggermente contaminata
slightly contaminated or critical.
o situazione critica.
- She's just amazing, she's taken advantage
È straordinaria.
of that knowledge and that passion
Usa le sue conoscenze e la sua passione
to build something that is for the benefit of humanity.
per creare qualcosa di utile per l'umanità.
Flint, Michigan
Flint, Michigan
- Coming to Flint
Dopo aver visitato Flint
just makes me want to work harder.
mi è venuta voglia di lavorare più duramente.
People are lined up for hours waiting to get bottled water,
Le persone stanno in fila per ore in attesa di ricevere l'acqua in bottiglia
which won't even last them a whole month.
che non basterà neanche per un mese.
I know my device only solves a small part
So che il mio dispositivo risolve solo una piccola parte
of this huge problem,
di questo enorme problema
but if people can test their water themselves,
ma se le persone possono testare da sole l'acqua
that gives them the power to do something about it.
hanno la possibilità di fare qualcosa in merito.
- Society tells you
La società ci dice
that you can't do certain things
che non possiamo fare determinate cose
because you are a child or because you are a female.
perché siamo piccoli o siamo donne.
Seeing someone like Gitanjali,
Conoscere qualcuno come Gitanjali
so eager, so smart, so prepared.
così appassionata, intelligente e preparata.
She's pushing the envelope, not only for herself
Sta superando i limiti, non soltanto per se stessa
but for other generations to come.
ma per le generazioni future.
To all those building a brighter future
A tutti coloro che stanno costruendo un futuro migliore
