Device that harvests water from air could be answer to water scarcityIt may not come as a surprise that Beth Koigi, a 26-year-old who grew up in Kimende on the outskirts of Nyahururu Town, is trying to solve water problems. Her father uses water supply technology to irrigate his farm, one of her brothers runs a company that makes water gutters and roofing, while the other is a water engineer who builds dams. Tired of battling waterborne infections, but too broke to afford a water purification system, she made a do-it-yourself water filter. Other challenges include the need for a lot of energy to condense water directly from the air. To resolve the challenge, Majik Water is using materials with high affinity for water molecules in air which easily capture these molecules, heats them and collects the water vapour released.
