New 98% Reflective White Paint Can End Global Warming

(p. A1) In 2020, Dr. Ruan and his team unveiled their creation: a type of white paint that can act as a reflector, bouncing 95 percent of the sun’s rays away from the Earth’s surface, up through the atmosphere and into deep space. A few months later, they announced an even more potent formulation that increased sunlight reflection to 98 percent.

The paint’s properties are almost superheroic. It can make surfaces as much as eight degrees Fahrenheit cooler than ambient air temperatures at midday, and up to 19 degrees cooler at night, reducing temperatures inside build-(p. A12)ings and decreasing air-conditioning needs by as much as 40 percent. It is cool to the touch, even under a blazing sun, Dr. Ruan said. Unlike air-conditioners, the paint doesn’t need any energy to work, and it doesn’t warm the outside air.

. . .

. . ., scientists have been urgently working to develop reflective materials, including different types of coatings and films, that could passively cool the Earth. The materials rely on principles of physics that allow thermal energy to travel from Earth along specific wavelengths through what’s known as the transparency or sky window in the atmosphere, and out into deep space.

Jeremy Munday, a professor of electrical and computer engineering at the University of California, Davis, who researches clean technology, said this redirection would barely affect space. The sun already emits more than a billion times more heat than the Earth, he said, and this method merely reflects heat already generated by the sun. “It’d be like pouring a cup of regular water into the ocean,” Dr. Munday said.

He calculated that if materials such as Purdue’s ultra-white paint were to coat between 1 percent and 2 percent of the Earth’s surface, slightly more than half the size of the Sahara, the planet would no longer absorb more heat than it was emitting, and global temperatures would stop rising.

. . .

While humans in such hot and picturesque places as Santorini and the aptly named Casablanca have long used white paint to cool dwellings, and municipalities are increasingly looking to paint rooftops white, Dr. Ruan said commercial white paints generally reflect 80 percent to 90 percent of sunlight. This means they still absorb 10 percent to 20 percent of the heat, which in turn warms surfaces and the ambient air. The Purdue paint, by comparison, absorbs so much less solar heat and radiates so much more heat into deep space that it cools surfaces to below-ambient temperatures.

Elderly Benefit Most from Air-Conditioning

(p. A18) The aging process makes older bodies generally less capable of withstanding extreme heat, doctors say.

“They’re at extremely high risk of heat stroke and death,” James H. Diaz, a professor of environmental and occupational health sciences at Louisiana State University’s School of Public Health, said of older people. “When we look at what happens with these heat waves, most of the deaths occur in the homebound elderly.”

In many communities, including in New Orleans and Houston, officials have opened cooling centers and shelters in recent weeks, with air-conditioned shuttle buses meandering through neighborhoods, picking people up. Programs are also in place to provide or repair air-conditioners or help people struggling to afford their electricity bills.

. . .

In . . . Orlando, Veronica King, 67, said she keeps her air-conditioner running even if she can’t afford to. “I have to figure out how to cover that bill,” she said, adding that she relies on machines that help her breathe. “When it’s hot, I can’t breathe.”

In Houston, where the heat index could reach 107 degrees on Sunday, Ms. Lowry and her husband, Jasper, 72, have come up with a compromise. They have two cars, neither with working air-conditioning. But they figured they could at least spare the money to repair it in one of them.

With No New Transmission Lines, 80 Percent of Planned Biden Emissions Reduction May Not Happen

(p. A12) . . ., compare today’s renewable energy and transmission system to one estimate of what it would take to reach the Biden administration’s goal of 100 percent clean electricity generation by 2035. Transmission capacity would need to more than double in just over a decade.

There are enormous challenges to building that much transmission, including convoluted permitting processes and potential opposition from local communities.

. . .

The climate stakes are high. Last year, Congress approved hundreds of billions of dollars for solar panels, wind turbines, electric vehicles and other technologies to tackle global warming. But if the United States can’t build new transmission at a faster pace, roughly 80 percent of the emissions reductions expected from that bill might not happen, researchers at the Princeton-led REPEAT Project found.

Already, a lack of transmission capacity means that thousands of proposed wind and solar projects are facing multiyear delays and rising costs to connect to the grid. In many parts of the country, existing power lines are often so clogged that they can’t deliver electricity from wind and solar projects to where it is needed most and demand is often met by more expensive fossil fuel plants closer to homes and businesses. This problem, known as congestion, costs the country billions of dollars per year and has been getting worse.

. . .

Utilities are sometimes wary of long-distance transmission lines that might undercut their local monopolies.

“Range Anxiety” Leads Chinese to Prefer Hybrids Over EVs

(p. B12) Don’t write off hybrid electric vehicles.

After Tesla, the most highly valued U.S.-listed EV company isn’t homegrown Rivian or Lucid but Li Auto, a Chinese manufacturer that went public in 2020 by listing American depositary receipts.

. . .

What is surprising is that Li has overtaken NIO to lead the new generation of Chinese startups. Li doesn’t make the purely electric vehicles that were popularized by Tesla and that have become the technological focus of other startups and most old-school car manufacturers. Instead, it specializes in extended-range EVs, which use a generator to power up the battery with gasoline if it runs out of juice.

. . .

The popularity of what is essentially a plug-in hybrid, albeit a cutting-edge one, is notable in the Chinese market, which has in many ways led the transition to EVs.

. . .

But Chinese charging infrastructure is patchy, leading to range anxiety. Brokerage Bernstein expects 65% growth in plug-in hybrid sales in China this year, versus 25% growth for pure EVs.

In “Hashing Things Out” to Save Lives Bateman “Could Be a Pit Bull”

(p. 20) Don Bateman, an engineer who invented a cockpit device that warns airplane pilots with colorful screen displays and dire audible alerts like “Caution Terrain!” and “Pull Up!” when they are in danger of crashing into mountains, buildings or water — an innovation that has likely saved thousands of lives — died on May 21 [2023] at his home in Bellevue, Wash.

. . .

Bob Champion, a former scientist at Honeywell who worked with Mr. Bateman, said in a telephone interview: “Don had a true passion for saving lives. He was a peach, but behind closed doors, when we were hashing things out, he could be a pit bull.”

. . .

“He never lost his childlike wonder about flying,” Ms. McCaslin said by phone. “He did a lot of his great work from his 40s on.”

. . .

Mr. Bateman told the National Science and Technology Medals Foundation in 2011 that in the late 1960s there were fatal accidents nearly every month, during which a pilot would “fly into something, like a mountain, or go in short on the runway.”

. . .

Determined to do something, Mr. Bateman developed — and in 1974 patented — his first ground proximity warning system: a small box that integrated data from within the aircraft, including the radar altimeter and airspeed indicator, and gave the pilot a 15-second warning of an approaching hazardous condition.

. . .

In the 1990s, the system improved exponentially. Engineers working with Mr. Bateman added GPS and critical terrain data, including topographical maps of Eastern Europe and China that had been charted by the Soviet Union as far back as the 1920s; they had been acquired in Russia at Mr. Bateman’s request.

“We knew, as engineers, that if we could get the terrain data, we could do an awful lot,” he told The Seattle Times.

Government Infrastructure Serves Elite More Than Ordinary Citizens

(p. A1) In a country where major industry and political fortunes alike are often tied to a vast, interwoven rail system, India has lavished public resources on new trains, but its purse strings have been much tighter when it comes to ensuring the safety of those already racing along its tracks.

Those decisions loomed large on Sunday [June 4, 2023] in the aftermath of a devastating train wreck that killed at least 275 people in eastern India.

. . .

Over the past years, India has been polishing its long-ramshackle infrastructure as never before, and its railways, which are at the heart of the world’s fifth-largest economy, have been a prime beneficiary. The government spent almost $30 billion on the rail system during the past fiscal year, up 15 percent from the year before.

But the amount spent on basic track maintenance and other safety measures has been falling. A report last year by India’s auditor general, an independent office, found that less money was being allocated for track renewal work and that officials had not even spent the full (p. A11) amount set aside.

. . .

. . . most of Mr. Modi’s initiatives have been aimed not at the basic steps needed to get trains from Point A to Point B without mishap, but at improving speed and comfort. He regularly extols higher-fare new electric Vande Bharat trains connecting bigger cities and has made an early priority of a Japanese-style bullet train, though it can do nothing to improve the lives of the country’s ordinary passengers.

Simple Beeping Pagers Tell Patients a Doctor’s Distraction Is Work-Related

(p. A10) Pagers, those pre-cellphone, one-way devices that alert the carrier that someone is trying to reach them, can seem like something out of a time capsule.

. . .

There are people who just refuse to let their pagers go, including some doctors and bird watchers. They say pagers allow them to separate parts of their life in a way phones don’t, and that the lower-tech one-way communication of a pager is less distracting than looking at a phone full of alerts and apps.

. . .

Another advantage of the pager? It’s easy for staff to throw one in frustration instead of turning on each other, according to Dr. Colm McCarthy, an orthopedic surgeon in Fall River, Mass.

Tired during a busy on-call night once, he chucked his pager in a closet where it broke.

He gave up his pager when he got his current job, and transitioned over to the apps on his phone. Now, though, when he gets a message on his phone, it’s awkward to answer it, he says. If he’s looking at the phone, he worries patients might wonder what he’s paying attention to while with a pager, it’s obvious it’s work.

He has multiple apps on his phone. Last year, his hospital adopted the fourth app that connects him to patients. When a patient wants to reach him, he gets a message with a phone number. He then has to call that number to get a message with the patient’s phone number.

The mute function on the apps is easily overridden by alerts, so to separate work from home life, he keeps his phone on silent altogether, he says. He often misses messages from family and friends because of that.

In Blackberry Movie “The Excitement of Disruption and the Thrill of Creation Become Tangible”

(p. C9) In Matt Johnson’s “BlackBerry” — a wonky workplace comedy that slowly shades into tragedy — the emergence of the smartphone isn’t greeted with fizzing fireworks and popping champagne corks. Instead, Johnson and his co-writer, Matthew Miller (adapting Jacquie McNish and Sean Silcoff’s 2015 book “Losing the Signal: The Untold Story Behind the Extraordinary Rise and Spectacular Fall of BlackBerry”), have fashioned a tale of scrabbling toward success that tempers its humor with an oddly moving wistfulness.

. . .

. . ., we’re in Waterloo, Ontario, in 1996, where Mike Lazaridis (a perfect Jay Baruchel) and Doug Fregin (Johnson) — best friends and co-founders of a small tech company called Research in Motion (RIM) — are trying to sell a product they call PocketLink, a revolutionary combination of cellphone, email device and pager.

. . .

The corporate types don’t understand Mike and Doug’s invention, but a predatory salesman named Jim Balsillie (a fantastic Glenn Howerton), gets it. Recently fired and fired up, Jim sees the device’s potential, making a deal to acquire part of RIM in exchange for cash and expertise. Doug, a man-child invariably accessorized with a headband and a bewildered look, is doubtful; Mike, assisted by a shock of prematurely gray hair, is wiser. He knows that they’ll need an intermediary to succeed.

Reveling in a vibe — hopeful, testy, undisciplined — that’s an ideal match for its subject, “BlackBerry” finds much of its humor in Jim’s resolve to fashion productive employees from RIM’s ebulliently geeky staff, who look and act like middle schoolers and converse in a hybrid of tech-speak and movie quotes. It’s all Vogon poetry to Jim; but as Jared Raab’s restless camera careens around the chaotic work space, the excitement of disruption and the thrill of creation become tangible.

Feds Impose Tariffs on Imports of Paper-Thin Steel Needed to Make EV Engines

(p. A3) Large U.S. steelmakers are ramping up production of a hard-to-make, paper-thin steel to capture a fast-growing market for a material critical to powering electric vehicles.

. . .

Such electrical steel, which accounts for about 1% of all the steel produced annually in the world, already is in short supply for electric vehicles, executives said. Companies expect demand to accelerate faster than production as EV volumes expand in the coming years.

“It’s in limited supply and with very long lead times. Sometimes 50 or 52 weeks,” said Hale Foote, owner of Scandic Springs Inc., a San Leandro, Calif., company that uses high-grade electrical steel to make parts for scientific measurement devices.

. . .

More than 80% of the electrical steel produced comes from China, Japan and South Korea, all countries that are subject to U.S. tariffs or quotas on steel imports, industry analysts said.

. . .

(p. B2) “It takes intense focus. You have to have absolute consistency or you scrap the material,” said David Stickler, who led the investment group that built Big River Steel in Osceola, Ark., and then sold the mill to U.S. Steel in 2021. Mr. Stickler said he envisioned electrical steel being a core product at Big River when he started planning the mill nearly a decade ago.

. . .

Steel-industry executives said that creating more domestic capacity to make electrical steel for vehicles will likely take years, as steel companies acquire equipment and become proficient at the exacting production process.

“You can’t just buy the equipment and start making electrical steel. Those who’ve made the investment will have an advantage for the next five to 10 years,” Mr. Stickler said.

“They Just Invest in How to Navigate This Bureaucracy”

(p. A1) Capella Space, a San Francisco-based start-up, is building a fleet of small, inexpensive satellites that can track enemy troops as they move at night, or under cloud cover that traditional optical satellites cannot see through.

Fortem Technologies, a small aerospace company in Utah, wants to supply the Pentagon with a new type of unmanned aircraft that can disable enemy drones.

HawkEye 360, a Virginia-based firm, has used private equity funds to launch its own satellites that use radio waves emitted by communications equipment and other electronic devices to detect the presence of enemy troop concentrations.

Each of these systems is getting real-world testing in the war in Ukraine, earning praise from top government officials there and validating investors who have been pouring money into the field.

But they are facing a stiff challenge on another field of battle: the Pentagon’s slow-moving, risk-averse military procurement bureaucracy.

When it comes to drones, satellites, artificial intelligence and other fields, start-up companies frequently offer the Pentagon cheaper, faster and more flexible options than the weapons systems produced by the handful of giant contractors the Pentagon normally relies on.

But while the military has provided small grants and short-term contracts to many start-ups, those agreements often expire too quickly and are not large enough for young companies to meet their payrolls — or grow as rapidly as their venture capital investors expect. Several have been forced to lay people off, delaying progress on new technologies and war-fighting tools.

. . .

(p. A8) From the early months of the war, SpaceX’s Starlink, the Elon Musk-founded satellite internet service, had played a critical role for frontline Ukrainian troops. But small drones and a denser collection of satellites are also helping to provide the capacity for pervasive surveillance, allowing Ukraine to identify and track threats and targets constantly.

A new generation of cheaper and more precise attack drones carrying bombs can loiter in the air autonomously until they find their targets. Artificial intelligence-backed computer systems can fuse this collected data and other feeds to make targeting decisions, faster than any human.

The Ukrainians have also innovated a great deal themselves, impressing Pentagon officials as they have converted commercial drones, for example, into mini bombers.

Taken together, said Thomas X. Hammes, who studies war-fighting history at the Pentagon-backed National Defense University, the developments represent a “genuine military revolution,” and one that is happening much more quickly than the shift from infantry that traveled by foot in World War I to the motorized and mechanized armies of World War II.

. . .

(p. A9) Perhaps the most revolutionary use of American technology in Ukraine has been the application of software that uses artificial intelligence, made by Palantir, to help with targeting efforts. The company’s chief executive, Alex Karp, traveled to Ukraine last year to meet with President Volodymyr Zelensky.

“If you go into battle with old school technology,” Mr. Karp said this year at an event to discuss artificial intelligence tools in warfare, “and you have an adversary that knows how to install and implement digitalized targeting in A.I., you obviously are at a massive disadvantage.”

Some experts say that artificial intelligence, which has been used in Ukraine to help sift through the massive loads of data being accumulated from surveillance, will ultimately prove as disruptive to the nature of war-fighting as nuclear weapons.

. . .

For Primer, the small artificial-intelligence firm based in downtown San Francisco, it was a breakthrough moment.

Not long after the war in Ukraine started, its engineers, working with Western allies, tapped into a tidal wave of intercepted Russian radio communications. It used advanced software to clean up the crackly sound, automatically translated the conversations, and most importantly, isolated moments when Russian soldiers in Ukraine were discussing weapons systems, locations and other tactically important information.

This same work would have taken hundreds of intelligence analysts to identify the few relevant clues in the mass of radio traffic. Now it was happening in a matter of minutes.

The findings were quickly matched up with other so-called open source intelligence streams, like geolocation data pulled from social media accounts, giving updates on the location of troops or equipment, that could be matched with surveillance video from drones or images from satellites.

“It’s getting situational awareness,” said Sean Gourley, the founder of Primer.

Yet at the same time, the Pentagon was still deciding when to move ahead with major purchases of its technology. The company was burning through its cash reserves too quickly, so Mr. Gourley laid off engineers and other staff members.

“These engineers are great at creating solutions to solve these problems, which is what matters,” Mr. Gourley said. “But there is the uncertainty: When is this contract going to close? It’s very, very hard to justify that spend.”

Mr. Gourley said he decided instead to invest more money in a government relations push, hiring a former top aide to the Senate Armed Services Committee to help the company promote its business in Washington.

“The big defense companies, they don’t really kind of invest in the tech,” he said. “They just invest in how to navigate this bureaucracy. That kind of sucks, but that’s how you’ve got to play this game.”

In interviews, nearly a dozen top executives of technology-oriented companies shared stories of stalled efforts or frustration.

Opponents of Geoengineering View Global Warming as Nature’s Just Punishment of Us for Our Indulging in Technology and Capitalism

(p. A13) Make no mistake—Mr. Myhrvold is concerned about climate change.  . . .

He laments that policy makers largely scorn geoengineering—human interventions in the Earth’s natural systems to thwart or neutralize climate change.

. . .

Geoengineering is about “deliberately trying to reduce climate change.” Excess CO2 traps a little less than 1% of heat from the sun, “so if we could make the sun 1% dimmer, we could shut off climate change.” When Mount Pinatubo, a volcano in the Philippines, erupted in 1991, it lowered world-wide temperatures by 1 degree Celsius for about 18 months. Human-emitted particulate pollution has historically offset about 20% of human-emitted CO2. “Ironically,” he says, “the Clean Air Act made our air better but hurt climate change.”

The simplest solar-radiation management scheme, Mr. Myhrvold says, “is to emit particles in the stratosphere to mimic Mount Pinatubo. We invented a particularly elegant way to do this with balloons and a pipe to the sky.” By “we,” he means Intellectual Ventures, the company Mr. Myhrvold founded in 2000 after leaving Microsoft, where he spent 13 years and rose to the position of chief technology officer. Intellectual Ventures “creates, incubates and commercializes” new inventions.

“Marine cloud brightening” is another solar-related intervention. “The idea is to increase the number and size of low clouds that form over the oceans so that more incoming sunlight bounces back into space instead of heating the ocean.” Scientists have proposed a variety of ways to do this. One, which Mr. Myhrvold’s company has explored, is to outfit ships with equipment to spray seawater into the air as they traverse the ocean. “The salt particles can serve as nuclei for water vapor to condense into droplets, thus forming clouds.”

. . .

“Opponents worry that once you have geoengineering, people won’t make sacrifices to cut emissions. They want a sword of Damocles hanging over humanity as a means to force us to follow their ideology.”

Mr. Myhrvold uses an analogy he describes as “horrible in some ways.” When the AIDS epidemic hit, some people saw it as punishment from God. “Their attitude was, ‘This is what you get if you indulge in the practices we don’t approve of.’ ” In climate change, he says, this moralistic attitude takes the following form: “I don’t like aspects of our society, I don’t like technology, I don’t like capitalism, and this is nature’s retribution. And so we have to change the way we live.” Such beliefs “have become a very powerful disincentive, particularly for academic researchers.”

. . .
