Ebola-utbrottet förra året.
through these more range-limited,
via kortare sträckor,
a look at some of the numbers,
på statistiken kring detta,
att gå på ett plan,
to go on the plane
till 17 andra personer.
to 17 other people.
other guy with SARS,
en bra superkraft.
of a great superpower.

be in this latency period
have the disease
spread the disease
from the top of the cabin
as you see in blue.
genom dessa mycket effektiva filter
through these very efficient filters
of pathogens near the outlets.

around multiple times
att passera ut genom filtret.
to go out through the filter.
is a pretty serious problem.
ett ganska allvarligt problem.
to go out and buy a plane,
digital luftflödesberäkning
with computational fluid dynamics,
is create these simulations
i ett flygplan och göra mätningar.
in and taking readings in the plane.
is you would start out
i tekniska uppsatser på internet.
in technical papers around the Internet.
i en 3D-mjukvara,
into this 3D-modeling software,
som jag just byggt, i många små delar,
that I just built into these tiny pieces,
the computer can better understand it.
så att datorn kan förstå den bättre.
the air goes in and out of the cabin,
genom kabinen,
tills datorn har räknat ut simuleringen.
the computer calculates the simulation.
with the conventional cabin is this:
i en vanlig kabin, är det här:
right into people's faces.
rakt i människors ansikten.
those two passengers
att de här två passagerarna
at that from the side,
sprider sig längs kabinen.
spreading across the length of the cabin.
"This is no good."
"Det här är inte bra".
more than 32 different simulations

are absolutely amazing.
swirling airflow patterns,
med luft som virvlar
here is sneezing again,
i mitten nyser igen,
på ett effektivt sätt
to effectively push that down
kan trycka ner smittämnena.
push those pathogens down.
at the same scenario
passenger sneezes,
that straight down into the outlet
to infect any other people.

sitting next to the middle guy
no pathogens at all.
för några smittämnen alls.
från det här hållet också.
if the middle passenger sneezes,
om passageraren i mitten nyser,
vid fönstret nyser
passenger sneezes
this mean for the world?
into real life,
till det verkliga livet,
som jag byggt här,
that I built over here,
airflow patterns coming down,
actually cost the world
could actually cost the world
mer än tre biljoner dollar.
att ta ett plan ur trafik
to take an airplane out of service
och flera miljoner dollar
and several million dollars
something essentially overnight
this through to certification,
fram till certifiering, flygtester,
regulatory approvals processes.
att bli godkänd av alla myndigheter.
that sometimes the best solutions
är den bästa lösningen
inte kunnat genomföras,
wouldn't have supported it.
som är tillräckligt avancerad
en gyllene tidsålder för innovation.
of you today is: why wait?
till er alla idag är: Varför vänta?
