US-born Lankan student builds water cleansing system
Attends Rio+20 Summit to display work:
US born Sri Lankan student Shayanth Sinnarajah, 18, attended the
Rio+20 Summit to display a water cleansing system.
In minutes and with the amount of force it takes to pump air into a
bike tyre, Sinnarajah can make 15 gallons of clean drinking water,
referred to in some circles as "blue gold."
Sinnarajah and his colleagues pump the dirty, undrinkable water
through a machine where it travels through four filters, each one
progressively letting in fewer pollutants, until the water reaches a
tank inside the 28-inch by 48-inch cart that contains the
water-cleansing system called LiTReS.
Sinnarajah, 18, who will be a freshman at UC Berkeley in the fall,
siphoned the pristine water into a glass and made a toast with his
colleague and friend, Lucia Herrmann, also a recent Gulliver graduate,
who is Yale University-bound.
The two are part of a team of 18 students at the Coral Gables school
who created the water filtration device based on clean energy that could
solve the water crisis in under-developed areas where safe drinking
water is a luxury for millions.
On Sunday, Sinnarajah, Herrmann and engineering teacher and project
coach Claude Charron were all in Rio de Janeiro, Brazil, to attend
The Gulliver students were invited to present their story of
innovation at the US Department of State's centre on Sunday.
