The inventors of a device that can pull enough clean drinking water for 100 people per day out of the air will receive a prize significantly higher than than the cost of producing their water - less than two cents per liter.

The $1.5 Million Water Abundance XPRIZE is funded by the Tata Group and Australian Aid.  It is being awarded to the Skysource/Skywater Alliance for a rather ingenious gadget called WEDEW, for Wood to Energy Deployed Water.

It fits inside a standard shipping container and imitates clouds by cooling warm air and collecting the condensation in a tank.  Power is provided by a built-in biomass gassifier that vaporizes organic material such as wood, turning it into biochar, a charcoal that can be added to soil to store carbon and help plants grow.

It can be deployed anywhere it's needed - the inventors envision disaster relief applications in arid and wet climates such as an "apartment building in Nairobi, a disaster zone after a hurricane in Manila, a rural village in Zimbabwe".  The biomass gassifier isn't fussy, it will use whatever local materials are available: wood chips, coconut shells, what have you.

"It's a carbon-negative technology," says California-based architect David Hertz who helped lead the project.  "I think the future of technologies is going to be moving to this restorative, regenerative model that actually helps to repair the damage we've done."
