A
Despite Kyle Tianshi being only a 15-year-old US high schooler，he has published five sci-fi novels.His fifth book Eventide was released in July.However，this may not be his most impressive achievement as Kyle just received the “Hero Award”，a $20,000 grand prize.It is the top honor in the California Youth Sustainability Awards.The competition aims to encourage and support young community leaders who are making a difference for sustainability in their communities by taking action for the planet.
Kyle，a sophomore from the Cambridge School in the US，received the honor for his portable invention called NEREID.The device can detect microscopic particles(粒子) in water by using a laser and microscope.These particles can be harmful to people and the environment.
Kyle came up with the idea for the invention based on his experience growing up in San Diego，California，the US.People had no access to unpolluted drinking water and his parents asked him not to drink tap water.Kyle spent about $60 buying the tools needed to analyze the tap water：a laser，a microscope and a micro-computer.“It’s incredibly powerful for the price，”Kyle said.Then he used their family’s garage as his laboratory，doing research on the pollution of drinking water caused by micro-plastics.
Kyle hopes to bring to market a low-cost alternative tool for detecting micro-plastic pollution levels in drinking water.In this way，he can offer help to people who don’t have access to water filtration(过滤) systems.He has applied for a patent.
Kyle said his sister Emily，a freshman at Stanford University，inspired his interest in environmental research.She was recognized nationally for developing a water collection device.They have founded the Clearwater Innovation program to advocate for clean water through social media platforms and organize community cleanup events.
