A startup in India is capturing the black particles that float in air pollution and turning them into ink.
Anirudh Sharma was at a conference in India when he noticed black particles accumulating on his white shirt. The specks settling on him were from pollution in the surrounding air.
Byproducts from burning fossil fuels such as gasoline and coal are causing health problems and climate effects around the world, especially in India’s growing cities. In that moment a few years ago, though, Sharma saw the pollution particles as something simpler: A coloring agent.
He went back to MIT Media Lab in Cambridge, Massachusetts, where he was a graduate student focused on augmented reality, and began working on an idea to turn carbon pollution into ink. Using candle soot to start, he came up with a prototype. After finishing his master’s degree, he went back to India and in 2016 co-founded a collaborative called Graviky Labs to continue working on Air-Ink and other ideas.
They developed a device that can be fitted onto the exhaust pipe of a car or portable generator and collected the soot that forms from burning diesel fuel. By mixing the fine black powder with solvents, they produced ink that then went into bottles and markers.
Kaushik says Air-Ink has a dual benefit: “It’s not just that we’re recycling that material into inks. What we are also doing is replacing the carbon black that otherwise would have been used to make black inks.” Manufacturers typically use the soot known as carbon black in rubber, ink, paints, and carbon paper.
After posting their endeavor on Kickstarter earlier this year, the team brought in $41,000—nearly three times the donations they sought to start producing Air-Ink in larger quantities. Through a sponsorship from a beer company, they’d already begun distributing the ink to artists, who created public pieces in London, Singapore, and other cities.

Why doesn't plastic biodegrade?? Most plastic is manufactured from petroleum the end product of a few million years of natural decay of once-living organisms. Petroleum’s main components come from lipids that were first assembled long ago in those organisms’ cells. So the question is, if petroleum-derived plastic comes from biomaterial, why doesn’t it biodegrade?
A crucial manufacturing step turns petroleum into a material unrecognized by the organisms that normally break organic matter down.
Most plastics are derived from propylene, a simple chemical component of petroleum. When heated up in the presence of a catalyst, individual chemical units monomers of propylene link together by forming extremely strong carbon-carbon bonds with each other. This results in polymers long chains of monomers called polypropylene. “Nature doesn’t make things like that,” said Kenneth Peters, an organic geochemist at Stanford University, “so organisms have never seen that before.” The organisms that decompose organic matter the ones that start turning your apple brown the instant you cut it open “have evolved over billions of years to attack certain types of bonds that are common in nature,” Peters told Life’s Little Mysteries. “For example, they can very quickly break down polysaccharides to get sugar. They can chew up wood. But they see a polypropylene with all its carbon-carbon bonds, and they don’t normally break something like that down so there aren’t metabolic pathways to do it,” he said.
But if all you have to do to make propylene subunits turn into polypropylene is heat them up, why doesn’t nature ever build polypropylene molecules?
According to Peters, it’s because the carbon-carbon bonds in polypropylene require too much energy to make, so nature chooses other alternatives for holding together large molecules. “It’s easier for organisms to synthesize peptide bonds than carbon-carbon bonds,” he said. Peptide bonds, which link carbon to nitrogen, are found in proteins and many other organic molecules.

Through their proprietary thermal demanufacturing process, PRTI takes whole car tires and turns them into oil, steel, carbon, and power. The business of turning tires into oil, steel, and carbon is lucrative, but the true value lies in monetizing the power in a new way.
Earlier this year, Standard American Mining and PRTI entered into a partnership to build the world’s first waste-to-energy cryptocurrency mine. They literally built a crypto mine on top of a persistent, renewable energy source that is completely independent from the utility grid, where they have 100% control over the power generation via the tire feed stock.
is transforming America’s billions of waste tires into valuable commodities in a green, revenue and energy producing, zero-waste process. PRTI was founded in 2013 to take a new, technology-focused approach to the global problem of waste tires. The company partners with tire manufacturers, waste management companies and state & local government to provide paid tire disposal services. PRTI generates additional revenue by selling the industrial commodities produced. The headquarters in Franklinton, NC has processed over 13 million pounds of waste rubber material.
Standard American Mining (www.standardamericanmining.com) is building the global infrastructure for the Supercompute Revolution. Our facilities leverage non-traditional, near-zero cost energy to increase global computing power capacity — a resource we believe to be the most valuable in the world.
China is building roadways with solar panels underneath that may soon have the ability to charge cars wirelessly and digitally assist automated vehicles. This second solar roadway project – part of the Jinan City Expressway – is a 1.2 mile stretch. The building technique involves transparent concrete over a layer of solar panels.
Construction is complete and grid connection is pending, but is expected to be complete before the end of the year.
The Jinan City solar highway is formed with three layers. The top layer is a transparent concrete that has similar structural properties with standard asphalt. The central layer is the solar panels – which are pointed out as being ‘weight bearing.’ The bottom layer is to separate the solar panels from the damp earth underneath. The road will be durable enough to handle vehicles as large as a medium sized truck.
It was noted by engineers that wireless vehicle charging could soon be integrated and automated car functions could take advantage of the inherent data in this this already wired roadway.

Designer Daan Roosegaarde has installed the “largest smog vacuum cleaner in the world” in Rotterdam to help improve the city’s air quality. The seven-meter-tall structure is designed to create a pocket of clean air in its vicinity, offering a respite from hazardous levels of pollution.
According to the designer, it processes 30,000 cubic meters of air per hour – removing ultra-fine smog particles and pumping out clean air using no more electricity than a water boiler. “The Smog Free Tower produces smog-free bubbles of public space, allowing people to breathe and experience clean air for free,” said a statement from Roosegaarde.
Roosegaarde‘s Smog Free Tower was unveiled on 4 September 2015 at Vierhavensstraat 52, following a successful Kickstarter campaign to help fund the project.
Here is an excerpt from the 2017 APA Mental Health on Climate white-paper that I found salient to read:
The ability to process information and make decisions without being disabled by extreme emotional responses is threatened by climate change. Some emotional response is
normal, and even negative emotions are a necessary part of a fulfilling life. In the extreme case, however, they can interfere with our ability to think rationally, plan our behavior, and consider alternative actions. An extreme weather event can be a source of trauma, and the experience can cause disabling emotions. More subtle and indirect effects of climate change can add stress to people’s lives in varying degrees. Whether experienced indirectly or directly, stressors to our climate translate into impaired mental health that can result in depression and anxiety (USGCRP, 2016). Although everyone is able to cope with a certain amount of stress,
the accumulated effects of compound stress can tip a person from mentally healthy to mentally ill. Even uncertainty can be a source of stress and a risk factor for psychological distress (Greco & Roger, 2003). People can be negatively affected by hearing about the negative experiences of others, and by fears—founded or unfounded—about their own potential vulnerability.
PHYSICAL HEALTH AND MENTAL HEALTH
Compromised physical health can be a source of stress that threatens psychological well-being. Conversely, mental health problems can also threaten physical health, for example, by changing patterns of sleep, eating, or exercise
and by reducing immune system function.
Although residents’ mental and physical health affect communities, the impacts of climate on community health can have a particularly strong effect on community fabric and interpersonal relationships. Altered environmental conditions due to climate change can shift the opportunities people have for social interaction, the ways in which they relate to each other, and their connections to the natural world.

Natural sunlight could soon be become a new, counter-intuitive, but innovative air-conditioner. Three Israeli entrepreneurs developed a way to turn energy from the sun, a source of heat, into a cooling agent that could save billions on electricity and have significant environmental, and even security, benefits.
Yaron Shenhav and Gadi Grottas, the co-founders of SolCold, and Hebrew University Professor Guy Ron have invented a high-tech, light-filtering coating that can be applied to buildings and other surfaces which is then activated by the sun, using its strong rays to cool down structures. In fact, the more the sun shines, the cooler it gets, the Herzliya-based company says.
It’s as if there were “a thin layer of ice that gets thicker and cooler as the sun gets stronger,” Shenhav tells NoCamels.
The paint is based on a patent-pending technology SolCold developed called Anti-Stokes Fluorescence, which reverses the natural phenomenon of energy (photons) released by the sun and then absorbed by everything around it, like roads, buildings, cars, tanks, cargo and so on.
GravityLight is an innovative device that generates light from the lift of a weight.
Combining kinetic and potential energy, GravityLight works by connecting an elevated weight — filled with rocks or sand — to a pulley system that slowly powers a generator as the weight falls to the ground.
Over 1.2 billion people globally have no access to electricity and millions more have an unreliable supply. Instead they use dangerous, polluting and expensive kerosene lamps for light.
Collectively, kerosene lamps cause 3% of the worlds CO2 emissions and are a significant source of black carbon, with even more intense local warming impact.
