Indian Startup to Produce Water from Thin Air

These days, the challenge of sustainability elicits many different creative responses: leather out of wine, air purifiers made of algae, even energy from cow and turkey poop. Truly the stranger, the better. A new project from an Indian startup company makes the sun and the wind come together to create water. How does that sentence make sense? Uravu answers our question.

The company’s affordable, electricity-free Aqua Panels use solar thermal energy to convert vapor into usable water – and they should be available to the public within two years. “There’s no need of any electricity or moving parts,” Uravu co-founder Swapnil Shrivastav told Quartz India. “It is just a passive device that you can leave on your rooftop and it will generate water. The process starts at night, and by evening next day you’ll have water.”

The process of producing water from vapor has already been developed and utilized before, mostly for industrial and agricultural purposes, but the outdated versions of this technology had to consume large amounts of energy and humidity—innovative, yes, but not yet as sustainable as the above-mentioned Aqua Panels. Uravu wants their device to suit domestic use.

“Initially we’ll be working with governments and strategic partners, and we want to reach places where there is water scarcity, such as parts of Rajasthan and Andhra Pradesh, and rural areas,” explained Shrivastav. “We will be trying to start with a household device and aim at community-level projects.”

Ultimately, the Indian company aims to make the process more simple to make it more accessible for people who lack resources. Sustainability takes many different forms, but surely it is best when it answers to society’s greatest needs.

Scientists Discover Snow On Mars

Most discoveries are a pleasant surprise. For two Florida students, unearthing vintage NASA suits was a jackpot find. The New Jersey Liberty Hall Museum is proudly boasting a wine older than the United States. But for planetary scientist Aymeric Spiga, discovering snow on Mars was beyond unexpected.

Mars is dry compared to Earth: Its cold nature makes it unlikely that any of the ice on the Red Planet’s surface would melt, and its extremely thin atmosphere would cause any liquid water on the surface to vaporize nearly immediately. Still, Mars’ atmosphere does possess clouds of frozen water.

Snowstorms on Mars are similar to Earthly microbursts, in which dense air zips downward from a cloud. Any snow landing on Mars would be quick to disappear. More often than not, Martian snow turns to vapor before even hitting the surface.

“This is something observed on Earth sometimes, with something called virga — streaks of rain falling from the clouds can vaporize before reaching the surface,”

What, then, does this phenomenon mean for how we depict Mars? Besides the fact that the little red planet continues to surprise us, its atmosphere is more dynamic than we thought. With a constant slew of new findings making an appearance, it seems we may get to know Mars on a more personal level.
