I'm as big a solar energy enthusiast as anyone — it is, literally, our best chance of preventing dangerous climate change — but I can understand the fact that some people find solar panels unsightly. Beauty is in the eye of the beholder — where I might see the bright, shiny energy source of the future, others will see an ugly metallic carbuncle. That means that not everyone wants to position panels on the roof of their home.
The obvious solution for those who don't like the look of solar panels (aside from less obvious solutions like giant solar crystal balls) are solar roof tiles. They look more or less like regular roof tiles.
But there's a new option for the aesthetically demanding: special windows that can capture the light that hits them.
Researchers at Los Alamos National Laboratory and the University of Milano-Bicocca have created a transparent solar window. They embedded quantum dots (nanocrystals made of semiconducting materials already used in solar panel systems to capture energy) into a transparent polymer. And because solar cells don't absorb all the light that hits them, light still comes through the window.
The real test, of course, will be whether these new window materials ever become cost competitive in the way that solar panels — and solar tiles, which use the same materials — are rapidly becoming. Because the technology is still being pioneered, it's still impossible to say. But considering how invisible solar windows would be in comparison to rooftop panels, this is almost certainly something lots of people will want, creating a large potential market. John Aziz
A businessman who remembers what it was like to rely on free lunches as a child approached the Wyoming Valley West School District in Pennsylvania with an offer he didn't think they would refuse.
Todd Carmichael, CEO and co-founder of La Colombe Coffee, said he told the school board president, Joseph Mazur, that he wanted to give the district $22,000 to wipe out all student lunch debt. Carmichael proposed the gift after learning that the district was sending letters to parents warning them that if they didn't pay the lunch money owned, they could be "sent to dependency court for neglecting your child's right to food," possibly leading to children being removed from their homes and put in foster care.
Mazur rejected his offer, Carmichael's spokesman Aren Platt told The Associated Press, saying the money is owed by parents who can afford to pay up. "The position of Mr. Carmichael is, irrespective of affluence, irrespective of need, he just wants to wipe away this debt," Platt said. Mazur did not return AP's phone calls.
A lawyer for the school board said he doesn't know what they plan on doing regarding lunch debt; previously, there had been talk of placing liens on properties and filing complaints in a district court. As for the foster care threat, Luzerne County child welfare agency officials said it's false to claim that parents who don't pay lunch debt could be sent to court, AP reports, and the school district needs to stop making this threat.

Special Counsel Robert Mueller will appear before the House Judiciary Committee on Wednesday with one of his longtime aides, Aaron Zebley, by his side, people familiar with the matter told The New York Times on Tuesday.
At the last minute, Mueller requested Zebley be sworn in as a witness, but instead, he will be there as Mueller's counsel, offering guidance on how to answer questions about the two-year investigation into Russian meddling in the 2016 presidential election and obstruction of justice.
Zebley was a deputy special counsel with "day-to-day oversight of the investigations conducted by the office," Mueller spokesman Jim Popkin said. Zebley was also Mueller's chief of staff when he served as FBI director. Mueller is also appearing before the House Intelligence Committee on Wednesday, but it's unclear if he made the same request to the panel. Catherine Garcia
Snap is finally on the upswing again after its disastrous 2018 redesign.
On Tuesday, Snapchat's parent company revealed the app gained 13 million new users in the second quarter, its largest boost since it went public in 2017. It also reported a boosted revenue of $388 million up 48% from a year earlier, sending stocks up 11% in post-market trading, The Wall Street Journal reports.
Snapchat had been either losing users or remaining stagnant from when it posted its IPO until the first quarter of 2019. It also saw a year of falling stock numbers, hitting a record low of $4.99 at the end of last year. Shares have since rebounded 180% to hit $16.50 after Snap shared its Q2 earnings Tuesday, though that's still below its debut price of $17, CNBC notes.
Snap's 203 million total user base exceeds the 192 million expectation analysts predicted for this quarter, Snap said on Tuesday. That's largely thanks to popular gender-swapping filters that apparently even helped one college student catch an alleged predator cop. An updated Android interface also helped retain and add users, Snap said. Snap expects its revenue and user base to continue growing in the third quarter, with an anticipated Q3 revenue of between $410 million and $435 million. Kathryn Krawczyk
You might want to get the tissues out for Supreme Court Justice Ruth Bader Ginsburg's eulogy for her former colleague, the late former Justice John Paul Stevens, who died last week at 99.
Ginsburg kept her remarks short and sweet, but they lent credence to reports that Stevens was not only a well-respected judicial mind, but a man of high character — with a sense of humor to go along with it.
Stevens was laid to rest in a private ceremony at Arlington National Cemetery on Tuesday, but CNN obtained a transcript of Ginsburg's eulogy. She spoke of how Stevens was actively playing sports and traveling across the Atlantic well into his 90s. In fact, the two of them saw each other at a conference in Lisbon, during what turned out to be the last week of Stevens' life.
On their last evening there, Ginsburg said she told Stevens that it was her dream to remain on the bench as long as he did. (Stevens, who served for 35 years, has the third longest Supreme Court tenure in U.S. history). Stevens' response? Stay longer.
At the end of the day, Ginsburg said, "in a capital city with no shortage of self-promoters" the "genuinely genial, unpretentious, and modest" Stevens "set a different tone." Read the full remarks at CNN. Tim O'Donnell
Harsher words have never been tweeted.
On Tuesday, a very confusing thread popped up on the account of U.K. Independent MP Jared O'Hara. It was seemingly written in the third person, calling "Jared" the "most disgustingly morally bankrupt person I have ever had the displeasure of working with." And that was far from the most incendiary comment in the thread.
The thread goes on to accuse O'Mara of having a "vile, inexcusable contempt for the people who voted you in" and relays the authors' fears that O'Mara will close down his whole office "once again" after this thread. The tweet's author then finally reveals himself as Gareth Arnold, whose Twitter bio says he "used to work for an MP."
O'Mara has had a troubled two years in Parliament, quickly coming under fire for misogynist and homophobic comments he made online long before his election. He soon resigned from the Labour party and became an independent. In April, he temporarily shut down his office after most of his staffers quit or were fired — something Arnold referenced in his tweets.
The thread stayed up for more than an hour, likely because of this reason Arnold tweeted from his own account.
So, just remembered he needs my phone to login to his Twitter. Shit. Sorry mate. Consider it payback for all the nonsense I said to people defending you.

Journalist Yashar Ali soon noted that Arnold is known for trolling right-wing politicians with massive online campaigns.
