    Couple Wins $1.5 Million for Making Water From Air

    The Skysource/Skywater Alliance co-founders David Hertz, left, and his wife Laura Doss-Hertz pose for a portrait next to the Skywater 300 Wednesday, Oct. 24, 2018, in Los Angeles. The company received the $1.5 million XPrize For Water Abundance for developing the Skywater 300, a machine that makes water from air.

    It started out modestly enough: David Hertz, having learned that under the right conditions you really can make your own water out of thin air, put a little contraption on the roof of his office and began cranking out free bottles of H2O for anyone who wanted one.

    Soon he and his wife, Laura Doss-Hertz, were thinking bigger — so much so that this week the couple won the $1.5 million XPrize For Water Abundance. They prevailed by developing a system that uses shipping containers, wood chips and other detritus to produce as much as 528 gallons (2,000 liters) of water a day at a cost of no more than 2 cents a quart (1 liter).

    The XPrize competition, created by a group of philanthropists, entrepreneurs and others, has awarded more than $140 million over the years for what it calls audacious futuristic ideas aimed at protecting and improving the planet. The first XPrize, for $10 million, went to Microsoft co-founder Paul Allen and aviation pioneer Burt Rutan in 2004 for SpaceShipOne, the first privately financed manned space flight.

    So when Hertz learned a couple of years ago that a prize was about to be offered to whoever could come up with a cheap, innovative way to produce clean fresh water for a world that doesn't have enough of it, he decided to go all in.

    Do Not Eat Any Romaine Lettuce: Health Officials

    [NATL] Do Not Eat Any Romaine Lettuce: Health Officials

    Health officials in the U.S. and Canada are urging people to stay away from all romaine lettuce and products after 32 people in 11 states were sickened by an E. coli outbreak.

    At the time, his little water-making machine was cranking out 150 gallons a day, much of which was being given to homeless people living in an around the alley behind the Studio of Environmental Architecture, Hertz's Venice Beach-area firm that specializes in creating green buildings.

    He and his wife, a commercial photographer, and their partner Richard Groden, who created the smaller machine, assembled The Skysource/Skywater Alliance and went to work. They settled on creating little rainstorms inside shipping containers by heating up wood chips to produce the temperature and humidity needed to draw water from the air and the wood itself.

    "One of the fascinating things about shipping containers is that more are imported than exported, so there's generally a surplus," says Hertz, adding they're cheap and easy to move around. And if you don't have wood chips to heat them with, coconut husks, rice, walnut shells, grass clippings or just about any other such waste product will do just fine.

    "Certainly in regions where you have a lot of biomass this is going to be a very simple technology to deploy," said Matthew Stuber, a professor of chemical and biomolecular engineering at the University of Connecticut and expert on water systems who was one of the panel's judges.

    He called their water-making machine a "really cool" merging of rather simple technologies that can be used to quickly deliver water to regions hit by natural disasters, stricken by drought or even rural areas with a shortage of clean water.

    Hertz and his wife are just starting to contemplate how to accomplish that.

    Judge Blocks Trump's Migrant Non-Port of Entry Asylum Ban

    [NATL] Judge Blocks Trump's Migrant Non-Port of Entry Asylum Ban

    An order from a federal judge overnight barred the Trump administration from blocking asylum requests from migrants who cross the U.S.-Mexico border illegally. This happens as a caravan criticized by President Donald Trump arrived in Tijuana, Mexico, across the border from San Diego.

    Theirs was among 98 teams from 27 countries who entered. Many teams were bigger and better funded while the couple mortgaged their Malibu home to stay in the game. At one point, they were told they hadn't made the final round of five but then one team that did dropped out and they were back in.

    "If you say we were the dark horse in the race, we weren't even in the race," Hertz recalled with a smile. He stood near a giant copy of the check in his office while his wife prepared to leave for a photo shoot and a visitor sampled a glass of their freshly made water.

    Now, though, they are in for the long, wet haul.

    "There's no restrictions whatsoever on how it's used," Hertz said of the prize money. "But Laura and I have committed to using it all for the development and deployment of these machines, to get them to people who need the water most."
