Millions of people around the world rely on water tanks -- yet there's no simple way to monitor water quantity or predict future needs. So 18-year-old inventor Zach Preston came up with a solution: a simple, solar-powered, cloud-based device that tracks water volumes and shares the relevant information with everyone who needs it, potentially transforming the way water is managed and monitored around the world.

Zach is an engineering student at the University of Canterbury and a keen teenage innovator. At the age of 18, he founded Sentinel Water: an eco-tech startup that aims to reimagine how tanked water supplies are managed sustainably and effectively. From pitching technology solutions to Microsoft in Seattle to being awarded Top of New Zealand AL Computer Science, Zach has always been fascinated by how technology can completely change the way people think and live. Having worked across several industries as a freelancer, Zach is deeply passionate about applying imagination and creative problem-solving to Aotearoa’s toughest problems through empathetic design. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
