"When a severe water shortage hit the Indian city of Kozhikode in the state of Kerala, a group of engineers turned to science fiction to keep the taps running.

Like everyone else in the city, engineering student Swapnil Shrivastav received a ration of two buckets of water a day collected from India’s arsenal of small water towers.

It was a ‘watershed’ moment for Shrivastav, who according to the BBC had won a student competition four years earlier on the subject of tackling water scarcity, and armed with a hypothetical template from the original Star Wars films, Shrivastav and two partners set to work harvesting water from the humid air.

“One element of inspiration was from Star Wars where there’s an air-to-water device. I thought why don’t we give it a try? It was more of a curiosity project,” he told the BBC.

According to ‘Wookiepedia’ a ‘moisture vaporator’ is a device used on moisture farms to capture water from a dry planet’s atmosphere, like Tatooine, where protagonist Luke Skywalker grew up.

This fictional device functions according to Star Wars lore by coaxing moisture from the air by means of refrigerated condensers, which generate low-energy ionization fields. Captured water is then pumped or gravity-directed into a storage cistern that adjusts its pH levels. Vaporators are capable of collecting 1.5 liters of water per day.

If science fiction authors could come up with the particulars of such a device, Shrivastav must have felt his had a good chance of succeeding. He and colleagues Govinda Balaji and Venkatesh Raja founded Uravu Labs, a Bangalore-based startup in 2019.

Their initial offering is a machine that converts air to water using a liquid desiccant. Absorbing moisture from the air, sunlight or renewable energy heats the desiccant to around 100°F which releases the captured moisture into a chamber where it’s condensed into drinking water.

The whole process takes 12 hours but can produce a staggering 2,000 liters, or about 500 gallons of drinking-quality water per day. [Note: that IS staggering! That's huge!!] Uravu has since had to adjust course due to the cost of manufacturing and running the machines—it’s just too high for civic use with current materials technology.

“We had to shift to commercial consumption applications as they were ready to pay us and it’s a sustainability driver for them,” Shrivastav explained. This pivot has so far been enough to keep the start-up afloat, and they produce water for 40 different hospitality clients.

Looking ahead, Shrivastav, Raja, and Balaji are planning to investigate whether the desiccant can be made more efficient; can it work at a lower temperature to reduce running costs, or is there another material altogether that might prove more cost-effective?

They’re also looking at running their device attached to data centers in a pilot project that would see them utilize the waste heat coming off the centers to heat the desiccant."

Roman's primary structure hangs from cables as it moves into the big clean room at NASA's Goddard Space Flight Center.

What Makes the Clean Room So Clean?

When you picture NASA’s most important creations, you probably think of a satellite, telescope, or maybe a rover. But what about the room they’re made in? Believe it or not, the room itself where these instruments are put together—a clean room—is pretty special. 

A clean room is a space that protects technology from contamination. This is especially important when sending very sensitive items into space that even small particles could interfere with.

There are two main categories of contamination that we have to keep away from our instruments. The first is particulate contamination, like dust. The second is molecular contamination, which is more like oil or grease. Both types affect a telescope’s image quality, as well as the time it takes to capture imagery. Having too many particles on our instruments is like looking through a dirty window. A clean room makes for clean science!

Two technicians clean the floor of Goddard’s big clean room.

Our Goddard Space Flight Center in Greenbelt, Maryland has the largest clean room of its kind in the world. It’s as tall as an eight-story building and as wide as two basketball courts.

Goddard’s clean room has fewer than 3,000 micron-size particles per cubic meter of air. If you lined up all those tiny particles, they’d be no longer than a sesame seed. If those particles were the size of 16-inch (0.4-meter) inflatable beach balls, we’d find only 3,000 spread throughout the whole body of Mount Everest!

A clean room technician observes a sample under a microscope.

The clean room keeps out particles larger than five microns across, just seven percent of the width of an average human hair. It does this via special filters that remove around 99.97% of particles 0.3 microns and larger from incoming air. Six fans the size of school buses spin to keep air flowing and pressurize the room. Since the pressure inside is higher, the clean air keeps unclean air out when doors open.

A technician analyzes a sample under ultraviolet light.

In addition, anyone who enters must wear a “bunny suit” to keep their body particles away from the machinery. A bunny suit covers most of the person inside. Sometimes scientists have trouble recognizing each other while in the suits, but they do get to know each other’s mannerisms very well.

This illustration depicts the anatomy of a bunny suit, which covers clean room technicians from head to toe to protect sensitive technology.

The bunny suit is only the beginning: before putting it on, team members undergo a preparation routine involving a hairnet and an air shower. Fun fact – you’re not allowed to wear products like perfume, lotion, or deodorant. Even odors can transfer easily!

It takes a lot of specialists to run Goddard’s clean room. There are 10 people on the Contamination Control Technician Team, 30 people on the Clean Room Engineering Team to cover all Goddard missions, and another 10 people on the Facilities Team to monitor the clean room itself. They check on its temperature, humidity, and particle counts.

A technician rinses critical hardware with isopropyl alcohol and separates the particulate and isopropyl alcohol to leave the particles on a membrane for microscopic analysis.

Besides the standard mopping and vacuuming, the team uses tools such as isopropyl alcohol, acetone, wipes, swabs, white light, and ultraviolet light. Plus, they have a particle monitor that uses a laser to measure air particle count and size.

The team keeping the clean room spotless plays an integral role in the success of NASA’s missions. So, the next time you have to clean your bedroom, consider yourself lucky that the stakes aren’t so high!

“Hey, you okay?”

“I…no.”

“Okay. Talk to me.”

“Phee…what if we made a mistake?”

“What?”

“There is hardly anywhere the Empire is not these days. What if something happens to one of us? To both of us? What if you go out on a mission for Vos and you are killed or”—

“It’s us, brown eyes. And it’s me. I’d like to see the Empire try to keep me down.”

“Then what if one day I wake up and I cannot remember you? Or the girls?”

“Then we’ll help you remember all over again. All of us.”

“But what if”—

“You were having that nightmare about Tantiss, weren’t you?”

“Yes. I…don’t want to…go back to being….”

“Listen, Tech Ninety-Nine Genoa: you are never going back to that ever again. I promise.”

For the day five prompt of ND Tech Week. I’m thinking it takes Tech a little while to get back home, and a little while longer to figure out who he really is. He still has some rough days, and worries in ways he didn’t before. Whatever happened to him, and whatever he did afterwards, was something he couldn’t control—and it kept him away for so much longer than he wanted. Still, every once in while it hits him how much they lost, and how much they got back, and in spite of everything he thinks he must be the luckiest man in the galaxy to have come out the other side. After all, better late than dead. As Phee always says. (Or did that one time.)

I feel like the other members of the batch (most likely Crosshair and Wrecker) would be acting out and not listening to Hunter, and Hunter would finally lose his shit and hit them with the “just WAIT until your father Echo gets home!”😡

had a whole ass "debate" with some dude bc he just doesnt like HOW solarpunk is anti establishment

bro just wants grimdark dystopian bullshit like we have always seen

"it's just trees / star trek"

tell me you dont understand what a good civilzation looks like without telling me

solarpunk is EVERYTHING other types of punk are... except it is bright.

what is wrong with that???

I am also searching for a brother of mine, so I understand it is easy to fall when you are ready to sacrifice anything.

Here are my plans, if you would listen. I am seldom wrong after all.
