Before Fulton Schools Associate Professor Cody Friesen developed solar panels that harvest water from the air, he achieved another technological advance: rechargeable high-energy batteries —zinc-air batteries — that are eco-friendly and affordable. Those breakthroughs propelled his Zero Mass Water startup, which is helping to provide clean water in locales with a range of climate conditions in more than 35 countries. As the venture has expanded, Friesen has applied for 88 patents in related technologies and won the 2019 Lemelson-MIT Prize for inventions that shoe strong potential for improving the world.
