Choose your favorite problem and contribute solving it | Gabriele Semino | TEDxFreiburg


today I would like to tell your story I
would like to tell your story about the
project I’ve been working on for the
last year
however I do not want this talk to be
about my life or the achievement of my
team I would rather like to tell you
this story to show what a team a group a
community of people working towards
solving a problem can achieve and how
important it is that every individual
and every group inside this community
give this contribution towards achieving
the general goal so would like to
encourage you to follow along my story
and maybe at some point you will start
getting the point I’m trying to make as
I mentioned this talk is about solving
problems so I would like to start by
mentioning one problem society’s facing
today it’s a problem that I’m sure
everybody of you had at some point in
his life every time you took your car
and went to work or on holiday as I’m
gonna do in a couple of weeks for
Christmas with my family knows of
situation like this one staying in
traffic in traffic for hours waiting and
trying to come to the destination as far
as possible well everybody in the car
next to you is trying to do the exact
same thing and if some of you adventures
enough to ever try to either go to work
by train or to go on holiday by airplane
you might have encountered situation
like this one you might have to find out
that the experience is not the best one
you could wish for and I would also like
to mention another problem which is
related to transportation which is a
problem that is not only affecting the
way we travel but the way we live and
the way we have to influence other lives
on this planet probably many of you in
Europe are not familiar with picture
like this one how the transportation is
one of the key factors
contribution contributing to the
emission of greenhouse gases and to
pollution around the world
silver 90% of all transportation system
use some sort of oil-based fuel the
situation is not getting better since
might weigh more people as trying to
move into cities and many more people
for the talk today I would like to
propose one solution and talk about a
solution proposed by a man which is
quite known however this problem is
getting a lot of attention all over the
world as many more people are realizing
the gravity of the situation the man I
would like to talk about could be known
for many of you many of you might know
him for his company Tesla which is
building electric cars and trying to
accelerate the transition to sustainable
transport or maybe some of you might
know him for his company SpaceX
which is building a new generation of
rockets and trying to reduce the cost of
going to space but in 2013 he had an odd
idea thinking about the problems we were
talking before he envisioned a new
transportation system a transportation
system that according to him could solve
all the problems we mentioned earlier
and so he decided to write a paper and
make this idea public he called this a
transportation system the Hyperloop now
what’s the idea behind the Hyperloop how
would it look like well in principle a
Hyperloop station would look that
different from a train station we have
today but instead of having trains and
rails in there you will probably find
big tubes and pots small capsules out of
it well why use tubes
what’s wrong with rails we have today
well while once one finds out that when
trains are trying to go faster and
faster the experience what’s called
aerodynamic drag that the same effect
you have if you pull your hand out of
the car while driving
you feel the force against your hand but
that is trying to lower your speed the
same thing happened to trains as well
when they’re traveling really fast so
the idea of using the tube is if I build
the tube and then I take lots of the air
outside of the tube then everything that
moves through this tube can move way
faster with less drag and that’s exactly
what’s the spots are for this parts can
transport around 30 to 40 people and
since they experience a dynamic drag
they can travel way faster then
everything we have today they can travel
up to the speed of sound which is over
thousand kilometers per hour
that would mean connecting cities like
San Francisco and Los Angeles or here in
Germany Munich and Berlin in slightly
over half an hour this is the vision
this inland mass proposed and but the
paper he published wasn’t a complete
design was not something I could be
readily built but rather what a concept
an idea
and so invited people around the world
to stop working on this idea and try to
make this concept a reality to
contribute with their own skill towards
making a final design and Bill and start
building tubes and so company around the
world started to be founded to really
work on this design and solve the
technical challenges that still need to
be addressed in order to have a final
system and other groups are on the wall
started to work with the technology as
well two years later you learn mosque
had a great idea he wanted young minds
and motivated students to start working
on this idea as well and so what he did
is he organized the competition together
with his company SpaceX this competition
is since then known as the SpaceX
Hyperloop pod competition the idea of
the competition is pretty simple
SpaceX build next to the headquarters in
California a 1.2 kilometers long tube
that could be used as a test track and
then the invited teams are on the world
to start developing a Hyperloop pod
that’s what happened at the first
competition more than thousand teams
around the world apply to take part in
it many students in particular around in
the university around the world decided
to join this adventure and try to build
something one of the teams that started
working on this was a small team of
students from our own University the
Technical University of Munich there
were only seven student that started
this new project inside a bigger student
initiative at my university which is
called var and as since then PS has
since 1960 to build rockets and
satellites and so since then this group
is known as VAR Hyperloop because it’s
inside this larger organization and they
started just seven student thinking big
and trying to trying to contribute with
their own expertise towards building a
Hyperloop design there were also only
seven students working in their free
time and working on an idea which had
been expressed by last couple of years
earlier but has never been built in real
life since this picture was taken in
2015 a lot have happened at my
university while this team was still
working on the for the first Hyperloop
pod competition a second competition was
announced and so a new group of students
decided to start working towards
building a second Hyperloop pod and
that’s when I joined the team you can
see here the pictures of the two
presentation of our Hyperloop pods you
can see a bigger part which was designed
in a way that intended to look how I had
to look particle look one day with a big
compressor up front for instance and
then a smaller Hyperloop pod designed
only towards achieve trying to achieve
the faster speed in the short track that
SpaceX built now would like to give you
an idea of how working a project like
this looks like
this is a video showing some clips we
took while working on this project you
know when you start building a Hyperloop
pod prototype it’s not like building a
car everybody know how a car looks like
but nobody knows how happy the pods
looks like so it takes hours of
discussion to decide which technologies
to use what to test what do you bring in
your design and what to build in the end
and even after you spend hours designing
and taking preparation to build your pod
it takes then way more hours to prepare
the hardware test the hardware and then
even when everything is status and
everything seems to work then you have
to put everything together put all the
pieces together and try to make it work
as a complex part you can imagine these
students worked all in the free time the
work days and very often nights to
finish this part in time for the
competition and you can imagine how
proud the student team is when then
finally their part is completed what I
like to talk about my team because
that’s where I spend a lot of my time in
the last year there are many other teams
around the world trying to build their
own Hyperloop pod here’s a picture of
the first competition you see every tent
belongs to one different groups coming
from somewhere in the world there were
teams from everywhere around the world
every team worked days and nights on
their Hyperloop design build their
Hyperloop pod and then came to Los
Angeles to test them you can see how
many students are working on this
project and only the best students were
allowed to join the competition many
more on the world are working as well
now you can imagine how important race
that inside a team everybody contributes
with their knowledge the expertise and
their time
for the team to achieve the goal of
joining the competition now before I
close my talk I would like to show a
video that I’m very proud of it was this
was our last test run at the last
competition the goal was to build the
fastest Hyperloop pod that could travel
through this rather short tube and this
thank you very much I think my team more
than me deserves this clause but the
part you see in the video reached 324
km/h and that one not only gave us a
chance to win the competition but we
actually also met with a man that
started all of this Elon Musk was nice
enough to stop by have a short chat with
us and then take this picture which we
have very proud of as well now I would
like to close this talk by making a
general point now you have seen how much
team can achieve or at least what a team
can achieve when they have a common goal
but you’ve also seen only a part of all
the problems that needs to be solved in
order for this to work so I would like
to invite you to become active and chose
the problem you want to solve I’m sure
everybody of you knows some problem that
needs to be solved in society I hope
that maybe after talk today you’re more
inspired to what trying to solve yours
while this talk today was a very
technical talk solving a problem which
it’s male mainly about engineering there
are many other problems in society that
needs to be solved in social issues
political issues issues in education and
so on so maybe if you’re not an engineer
you can try and solve a problem yourself
in particular if you are student I
always hope that other students like the
one that participated in this project
feel inspired but what my team is doing
and maybe is will start to work on
something themself so please pick your
favorite problem and start contributing
soon we’re solving it thank you very
much [Applause]
