Wang, 17, won the world’s largest high school science competition on
Friday, taking home the top prize of US$75,000 for inventing a new way to keep
germs from spreading in airplane cabins.
“It’s very exciting. I
absolutely did not expect it,” Wang said by telephone from
Pittsburgh, host city for the finals of the Intel International
Science and Engineering Fair. “It’s literally the happiest day of my life.”
Wang started thinking
about the problem of disease transmission on airplanes in December, after a
steady stream of news about the Ebola
outbreak in West Africa. Ebola is not spread through the air, he
learned, but other contagious diseases — including the H1N1
“swine” flu virus and SARS virus — are spread through the air.
And that’s a problem in
the cramped confines of airplane cabins, where everyone is breathing everyone
else’s air.
As Wang puts it: “With
the traditional cabin, what’s happening is you’ve got two large, turbulent
swirls happening. You’re spreading disease across the rows and longitudinally.”
Can you say that more
plainly? “When someone sneezes, there’s a mess everywhere.”
Here’s Wang’s video
simulation of airflow in a “traditional cabin,” i.e. the cabin that we’re
all subjected to when we fly now and his simulation of airflow in a cabin
modified with his device:

Wang said he decided to
tackle the problem when he discovered that few people in the airline industry
were actively working on ways to improve the quality of airplane air.
He created
high-resolution simulations of airflow inside the cabin of a commercial
aircraft — a Boeing 737, to be specific. And then he used those simulations
to design fin-shaped devices that fit into the airplane’s existing air
inlets.
The fins redirect the
airflow, creating virtual walls of air around each passenger. Each
person gets what Wang calls a “personalized ventilation zone” where
sneezes are vanquished, pushed out of the cabin before they can spread in a
turbulent burst.
His invention would
improve the availability of fresh air in the cabin by 190 percent, he said, and
would reduce the concentration of airborne germs by 55 times. Wang estimates
that it would cost $1,000 per airplane and could be installed overnight, making
it easy and economical for airlines.
And yes, he’s already
filed an application for a patent.
Wang is clearly not your
average high school student. He did his project not for class but on the side,
and he learned what he needed to know pretty much on his own, he said. “This
year I had to pick up from scratch computational fluid dynamics,” he said.
“I kept going with it, watching some videos, looking at some papers.”
This is Wang’s first win
at Intel’s big international fair, but it isn’t his first invention. He
also invented a device that generates electricity from the impact energy of
rain falling on roofs, as well as a self-cleaning outdoor garbage can.
Now finishing his junior year in high school, he says he wants to study
engineering and business in college.
“It’s one thing to be
able to come up with these great ideas, but another thing to be able to promote
them to the entire world,” he said.
Wang said he has long
dreamed of competing in Intel’s international fair, and the experience has
lived up to his expectations. “Basically a lot of this work is master’s or
PhD-level research, and to see so many people sharing the same passions all
gathered in one place, coming from across the world, is a very surreal
experience,” he said.

Two runners-up each
received US$50,000. They included Wang’s fellow Canadian, Nicole Ticea, 16, who
developed an inexpensive, disposable and electricity-free HIV-testing device
for use in low-income communities. Ticea has already founded her own company to
continue developing her technology.
Karan Jerath, 18, of Texas,
was also a runner-up. Jerath refined a device to allow an undersea oil well to
recover after a blowout.
