Check out our tablets for kids, learning toys and educational games.In a new paper published today in Nature, the team calculates how much this type of device could potentially help give more people access to water that’s safe to drink. The design, called an atmospheric water harvester, pulls in outside air, then uses fans and heat from sunlight to create condensation, producing clean drinking water drip by drip.Prepare your child for a lifetime of learning with educational toys from LeapFrog.

When the air is too dry, for example, the devices don’t work well, but the study found that 1 billion people who currently don’t have safe drinking water live in places where the device would function well.Because larger water infrastructure projects, like desalination plants, take many years to plan and build, the small devices could help fill the gap in the meantime. Then it compared those locations with the ideal climate conditions for using an atmospheric water harvester. The X team used World Health Organization datasets to map out, for the first time, exactly where those people live.
“The other 99.9% is for things like bathing and cleaning the dishes and agriculture and things like that. The project started in 2017.“One-tenth of 1% of the clean water in the world goes into our mouths,” says Astro Teller, the head of X. The team had tried to find ways to generate clean water multiple times, but only began focusing on atmospheric water harvesting after realizing that it could narrow its scope to think only about drinking water, not water used for other purposes.
A fan pulls in outside air and a desiccant absorbs moisture from it. (Some others, like a startup called Source, use a related design.) It has few parts. It uses only a few solar photovoltaic cells to power its fans, and relies mostly on solar heat. But, in many places, it can provide sufficient drinking water.The device is designed to work off-grid, and eliminate every possible expense.
