Tesla’s solar roof is gradually rolling out to more homes. A new set of photos shared this week show a new installation at twilight, complete with cutouts for chimneys and other features. The design looks impressive, and it’s one of the few sightings seen on social media since the first installations appeared early last year.
The roof was shared by a now-deleted Twitter account, which was subsequently posted to Reddit by a user called “Potatochak,” where it received over 3,000 upvotes on the Tesla subreddit. The depicted tiles appear to be the textured variety, but the company also offers a smooth style depending on cosmetic appearance. Tesla recommends a normal house uses a mix of 35 percent solar tiles at $42 per square foot to 65 percent “dummy” tiles at $11 per square foot, resulting in an average price of $21.85 per square foot, but it’s unclear how many times are operational in these images.
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.

A group of researchers at the Argonne National Laboratory have developed a sponge that will collect oil from bodies of water, which could improve how harbors and ports are cleaned, as well as how oil spills are managed.
“The Oleo Sponge offers a set of possibilities that, as far as we know, are unprecedented,” said co-inventor Seth Darling, a scientist with Argonne’s Center for Nanoscale Materials and a fellow of the University of Chicago’s Institute for Molecular Engineering.
At tests at a giant seawater tank in New Jersey called Ohmsett, the National Oil Spill Response Research & Renewable Energy Test Facility, the Oleo Sponge successfully collected diesel and crude oil from both below and on the water surface.
“The material is extremely sturdy. We’ve run dozens to hundreds of tests, wringing it out each time, and we have yet to see it break down at all,” according to Darling.
The team is actively looking to commercialize the material; those interested in licensing the technology or collaborating with the laboratory on further development may contact firstname.lastname@example.org.
