Teen Produces Both Clean Energy AND Fresh Water

Google has announced the finalists of this year’s Google Science Fair and the line-up is impressive. But among the 15 inventions designed to make the world a better place, Cynthia Sin Nga Lam’s submission is definitely a major standout. Concerned about the millions of people living without energy and water, the 17-year-old student scientist from Australia built H2Pro – a Portable Photocatalytic Electricity Generation and Water Purification Unit that produces both clean energy and fresh water at the same time.

With the H2Pro, Cynthia aims to tackle two problems at once: how to provide clean water and electricty to the many people around the world who have neither. Currently 780 million people lack access to clean water, while 1.2 billion live without electricity. The H2Pro could change that using photocatalytic technology, which simultaneously purifies water and generates electricity using only sunlight.

In her application, Cynthia explains that while investigating photocatalysis, she stumbled upon the idea of the H2Pro.

“In photocatalysis, not only water is purified and sterilized, but hydrogen is also produced through water-splitting, which can be used to generate electricity,” says Cynthia.
