travel across the world,
私は家族と世界を横断します
country of India.
for its scorching heat and humidity.
悪名高い国ですが
is to drink plenty of water.
唯一の方法は大量の水を飲む事です
to only drink boiled or bottled water,
飲まないよう いつも念を押していました
and easily get clean, potable water,
清潔な飲み水が手に入らないからです
大抵汚染されています
飲み水が安全だと
ならないのです
幸運にも私達のように
飲める訳ではないのです
in the busy streets of India,
インドでも混雑した通りで
バケツに水を汲む為に
年の子ども達が
from streams on the roadside.
目にしたことさえあります
はばかられる水を
見方が変わりました
社会的不公平を目の当たりにして
解決策を見つけたいと
why these kids lacked water,
生活に不可欠な水が不足しているのか
地球規模で水の危機に
is covered in water,
水で覆われています
of that is freshwater,
その僅か2.5%に過ぎず
of Earth's freshwater supply
利用出来ないのです
and economic growth,
高まっていますが
are rapidly depleting.
急速に枯渇しつつあるのです
World Health Organization,
is a leading cause of death
5歳以下の子どもの
in developing countries,
毎日 3千人の子ども達が
a water-related disease.
亡くなっていると見積もっています
one summer in eighth grade,
帰国した後
to combine my passion
水の危機を解決しようという情熱と
into a laboratory.
思ったのです
my kitchen into a laboratory,
台所を研究室に変えたのですが
and kicked me out.
on water-related research,
学術論文を数多く読み
in developing countries,
SODISと呼ばれる手法が
使われていると知りました
are filled with contaminated water
汚染水を入れます
for six to eight hours.
それを太陽に晒します
of these harmful pathogens
DNAを破壊し
and energy-efficient,
省エネでもあるのですが
when it's cloudy.
2日もかかります
the SODIS process faster,
稼働速度を上げる為に
新たな方式が
一体どんなものでしょうか?
that speeds up a reaction.
「反応の速度を上げるもの」です
this solar disinfection process.
速度を早めるのです
and strikes a photocatalyst,
TiO2つまり酸化チタンのような
really reactive oxygen species,
超酸化物、過酸化水素、
and hydroxyl radicals.
活性酸素種を生み出すのです
バクテリアや有機物等の
from drinking water.
除去する事が出来るのです
there are several disadvantages
光触媒式SODISの
is currently deployed.
幾つかの欠点があります
the clear plastic bottles
透明なペットボトルを使い
with this photocatalytic coating.
コーティングを施します
on the inside of these bottles,
コーティングを施すと
some of the UV radiation
紫外線をブロックし
of the process.
低下させてしまうのです
光触媒コーティングは
to the plastic bottle,
固く結合しません
and people end up drinking the catalyst.
人は光触媒を飲み込んでしまう事になるのです
不活性である一方で
if you keep drinking the catalyst,
本当に非効率です
to continue to replenish it,
補充しなければならないのです
to overcome the disadvantages
費用対効果の高い
method of purifying water.
生み出す事となりました
science fair project
科学フェアプロジェクトは
for water purification.
光触媒の複合物へと育ちました
titanium dioxide with cement.
セメントを結合させたものです
into several different shapes,
様々な異なる形状に変えられ
versatile range of deployment methods.
利用ができるのです
inside water bottles for individual use
that can filter water for families.
透過性のフィルターにも出来るのです
of an existing water tank
コーティングすることで
over a longer period of time.
長い期間に渡って届ける事も出来ます
私の辿った道のりは
to a sophisticated laboratory.
研究室もありませんでした
私は14歳でしたが
in pursuing scientific research
諦めようとは思わず
the global water crisis.
解決したいと思いました
just the universal solvent.
万能な溶媒ではありません
on this science fair project from 2012
この技術をもたらそうと 2012年から
into the real world.
取り組み続けているのです
I founded Catalyst for World Water,
「Catalyst for World Water」という
solutions to the global water crisis.
救うことを目的とした社会事業を起こしました
can't do much,
あまり多くの事は出来ませんが
維持することが出来るのです
come together to form oceans,
海になるのと正に同じように
取り組む時
ABOUT THE SPEAKER
Deepika Kurup - Inventor, student scientistWater is the basis of life, and too many people around the world suffer from waterborne illnesses. Deepika Kurup is working to change that.
Why you should listen
Deepika Kurup is a scientist, speaker, social entrepreneur and student at Harvard University. She has been passionate about solving the global water crisis ever since she was in middle school. After witnessing children in India drinking dirty water, Kurup developed a water purification system that harnesses solar energy to remove contaminants from water.
Recognized as "America’s Top Young Scientist" in 2012, Kurup won the grand prize in the Discovery Education 3M Young Scientist Challenge. In 2014 she was honored with the "United States President's Environmental Youth Award" and represented the United States in Stockholm, Sweden at the international Stockholm Junior Water Prize. Most recently Kurup was named one of the Forbes' "30 Under 30: Energy" and was the National Geographic Explorer Award Winner in the 2015 Google Science Fair. She attended the 2016 (and 2013) White House Science Fair. Currently she is CEO and founder Catalyst for World Water, a social enterprise aimed at deploying the technology she developed in water-scarce areas.
Along with research, Kurup is passionate about STEM education, and she feels that STEM education has the power to revolutionize the world. In her free time, she enjoys giving talks and writing articles to encourage students all around the world to pursue science, technology, engineering and math, and to increase awareness of the global water crisis. She has been invited to speak at schools, international conferences and the United Nations.
