“It’s true that both plants are not yet operating at the capacity we originally targeted,” said the Climeworks spokesperson.

“Like all transformative innovations, progress is iterative, and some steps may take longer than anticipated,” they said.

The company’s prospective third plant in Louisiana aims to remove 1 million tons of carbon a year by 2030, but it’s uncertain whether construction will proceed under the Trump administration.

A Department of Energy spokesperson said a department-wide review was underway “to ensure all activities follow the law, comply with applicable court orders and align with the Trump administration’s priorities.” The government has a mandate “to unleash ‘American Energy Dominance’,” they added.

Direct air capture’s success will also depend on companies’ willingness to buy carbon credits.

Currently companies are pretty free to “use the atmosphere as a waste dump,” said Holly Buck, assistant professor of environment and sustainability at the University at Buffalo. “This lack of regulation means there is not yet a strong business case for cleaning this waste up,” she told CNN.

Another criticism leveled at Climeworks is its failure to offset its own climate pollution. The carbon produced by its corporate activities, such as office space and travel, outweighs the carbon removed by its plants.

The company says its plants already remove more carbon than they produce and corporate emissions “will become irrelevant as the size of our plants scales up.”

Some, however, believe the challenges Climeworks face tell a broader story about direct air capture.

This should be a “wake-up call,” said Lili Fuhr, director of the fossil economy program at the Center for International Environmental Law. Climeworks’ problems are not “outliers,” she told CNN, “but reflect persistent technical and economic hurdles faced by the direct air capture industry worldwide.”

“The climate crisis demands real action, not speculative tech that overpromises and underdelivers.” she added.

Some of the Climeworks’ problems are “related to normal first-of-a-kind scaling challenges with emerging complex engineering projects,” Buck said.

But the technology has a steep path to becoming cheaper and more efficient, especially with US slashing funding for climate policies, she added. “This kind of policy instability and backtracking on contracts will be terrible for a range of technologies and innovations, not just direct air capture.”

Direct air capture is definitely feasible but its hard, said MIT’s Buck. Whether it succeeds will depend on a slew of factors including technological improvements and creating markets for carbon removals, he said.

“At this point in time, no one really knows how large a role direct air capture will play in the future.”

A nuclear fusion power plant prototype is already being built outside Boston. How long until unlimited clean energy is real?
жесток порно видео
In an unassuming industrial park 30 miles outside Boston, engineers are building a futuristic machine to replicate the energy of the stars. If all goes to plan, it could be the key to producing virtually unlimited, clean electricity in the United States in about a decade.

The donut-shaped machine Commonwealth Fusion Systems is assembling to generate this energy is simultaneously the hottest and coldest place in the entire solar system, according to the scientists who are building it.

It is inside that extreme environment in the so-called tokamak that they smash atoms together in 100-million-degree plasma. The nuclear fusion reaction is surrounded by a magnetic field more than 400,000 times more powerful than the Earth’s and chilled with cryogenic gases close to absolute zero.

The fusion reaction — forcing two atoms to merge — is what creates the energy of the sun. It is the exact opposite of what the world knows now as “nuclear power” — a fission reaction that splits atoms.

Nuclear fusion has far greater energy potential, with none of the safety concerns around radioactive waste.

SPARC is the tokamak Commonwealth says could forever change how the world gets its energy, generating 10 million times more than coal or natural gas while producing no planet-warming pollution. Fuel for fusion is abundant, derived from deuterium, found in seawater, and tritium extracted from lithium. And unlike nuclear fission, there is no atomic waste involved.

The biggest hurdle is building a machine powerful and precise enough to harness the molten, hard-to-tame plasma, while also overcoming the net-energy issue – getting more energy out than you put into it.
“Basically, what everybody expects is when we build the next machine, we expect it to be a net-energy machine,” said Andrew Holland, CEO of the Fusion Industry Association, a trade group representing fusion companies around the globe. “The question is, how fast can you build that machine?”

Commonwealth’s timeline is audacious: With over $2 billion raised in private capital, its goal is to build the world’s first fusion-fueled power plant by the early 2030s in Virginia.

“It’s like a race with the planet,” said Brandon Sorbom, Commonwealth’s chief science officer. Commonwealth is racing to find a solution for global warming, Sorbom said, but it’s also trying to keep up with new power-hungry technologies like artificial intelligence. “This factory here is a 24/7 factory,” he said. “We’re acutely aware of it every minute of every hour of every day.”

During a May 19 town hall meeting with NIH staff members, Jay Bhattacharya, the institute’s new director, equivocated when asked about funding cuts for research into improving the health of racial and ethnic minorities — cuts made under the guise of purging DEI from the government.

According to a recording of the meeting obtained by KFF Health News, Bhattacharya said the agency remained “absolutely committed to advancing the health and well-being of every population, including minority populations, LGBTQ populations, and every population.”

Research addressing the health needs of women and minorities is “an absolute priority of mine,” he said. “We’re going to keep funding that.” But a study considering whether “structural racism causes poor health in minority populations” is “not a scientific hypothesis.”

“We need scientific ideas that are actionable, that improve the health and well-being of people, not ideological ideas that don’t have any chance of improving the health and well-being of people,” he said. That comment angered many staffers, several said in interviews. Many got up and walked out during the speech, while others, watching remotely, scoffed or jeered.

Several current and former NCI scientists questioned Bhattacharya’s commitment to young scientists and minorities. Staffing cuts early in the year eliminated many recently hired NCI scientists. At least 172 National Cancer Institute grants, including for research aimed at minimizing health disparities among racial minorities or LGBTQ+ people, were terminated and hadn’t been reinstated as of June 16, according to a KFF Health News analysis of HHS documents and a list of grant terminations by outside researchers.

Those populations have higher rates of certain cancer diagnoses and are more likely to be diagnosed later than white or heterosexual people. Black people are also more likely to die of many cancer types than all other racial and ethnic groups.

Я решил купить доступ в VIP Club после навязчивой рекламы о «цифровых инвестициях будущего». На первом этапе всё выглядело красиво: личный кабинет, токены, бонусы. Но как только я попытался узнать, на каком блокчейне работают токены — нигде никакой информации. Поддержка игнорирует, а сайт постоянно предлагает «купить ещё». Это обман, прикрытый модными словами.

President Donald Trump on Thursday blamed the Federal Aviation Administration’s “diversity push” in part for the plane collision that killed 67 people in Washington, DC. But DEI backers, including most top US companies, believe a push for diversity has been good for their businesses.

Trump did not cite any evidence for how efforts to hire more minorities, people with disabilities and other groups less represented in American workforces led to the crash, saying “it just could have been” and that he had “common sense.” But Trump criticized the FAA’s effort to recruit people with disabilities during Joe Biden’s administration, even though the FAA’s Aviation Safety Workforce Plan for the 2020-2029 period, issued under Trump’s first administration, promoted and supported “the hiring of people with disabilities and targeted disabilities.”

It’s not the first time opponents of diversity, equity and inclusion initiatives, or DEI, have said they can kill people. “DEI means people DIE,” Elon Musk said after the California wildfires, criticizing the Los Angeles Fire Department and city and state officials for their efforts to advance diversity in their workforces.

Unity and BrightBuilt factory-built homes share an important feature: They are airtight, part of what makes them 60% more efficient than a standard home. GO Logic says its homes are even more efficient, requiring very little energy to keep cool or warm.

“Everybody wants to be able to build a house that’s going to take less to heat and cool,” said Unity director Mark Hertzler.

Home efficiency has other indirect benefits. The insulation and airtightness – aided by heat pumps and air exchangers – helps manage the movement of heat, air and moisture, which keeps fresh air circulating and mold growth at bay, according to Hertzler.

Buntel, a spring allergy sufferer, said his Somerville home’s air exchange has made a noticeable difference in the amount of pollen in the house. And customers have remarked on how quiet their homes are, due to their insulation.

“I’m from New England, so I’ve always lived in drafty, uncomfortable, older houses,” Buntel said. “This is really amazing to me, how consistent it is throughout the year.”
Some panelized home customers are choosing to build not just to reduce their carbon footprint, but because of the looming threat of a warming planet, and the stronger storms it brings.

Burton DeWilde, a Unity homeowner based in Vermont, wanted to build a home that could withstand increasing climate impacts like severe flooding.

“I think of myself as a preemptive climate refugee, which is maybe a loaded term, but I wasn’t willing to wait around for disaster to strike,” he told CNN.

Sustainability is one of Unity’s founding principles, and the company builds houses with the goal of being all-electric.

“We’re trying to eliminate fossil fuels and the need for fossil fuels,” Hertzler said.

Goodson may drill oil by day, but the only fossil fuel he uses at home is diesel to power the house battery if the sun doesn’t shine for days. Goodson estimated he burned just 30 gallons of diesel last winter – hundreds of gallons less than Maine homeowners who burn oil to stay warm.

“We have no power bill, no fuel bill, all the things that you would have in an on-grid house,” he said. “We pay for internet, and we pay property taxes, and that’s it.”

The bow of a US Navy cruiser damaged in a World War II battle in the Pacific has shone new light on one of the most remarkable stories in the service’s history.

More than 80 years ago, the crew of the USS New Orleans, having been hit by a Japanese torpedo and losing scores of sailors, performed hasty repairs with coconut logs, before a 1,800-mile voyage across the Pacific in reverse.

The front of the ship, or the bow, had sunk to the sea floor. But over the weekend, the Nautilus Live expedition from the Ocean Exploration Trust located it in 675 meters (2,214 feet) of water in Iron Bottom Sound in the Solomon Islands.

Using remotely operated underwater vehicles, scientists and historians observed “details in the ship’s structure, painting, and anchor to positively identify the wreckage as New Orleans,” the expedition’s website said.

On November 30, 1942, New Orleans was struck on its portside bow during the Battle of Tassafaronga, off Guadalcanal island, according to an official Navy report of the incident.

The torpedo’s explosion ignited ammunition in the New Orleans’ forward ammunition magazine, severing the first 20% of the 588-foot warship and killing more than 180 of its 900 crew members, records state.

The crew worked to close off bulkheads to prevent flooding in the rest of the ship, and it limped into the harbor on the island of Tulagi, where sailors went into the jungle to get repair supplies.

“Camouflaging their ship from air attack, the crew jury-rigged a bow of coconut logs,” a US Navy account states.
With that makeshift bow, the ship steamed – in reverse – some 1,800 miles across the Pacific to Australia for sturdier repairs, according to an account from the National World War II Museum in Louisiana.

Retired US Navy Capt. Carl Schuster described to CNN the remarkable skill involved in sailing a warship backwards for that extended distance.

“‘Difficult’ does not adequately describe the challenge,” Schuster said.

While a ship’s bow is designed to cut through waves, the stern is not, meaning wave action lifts and drops the stern with each trough, he said.

When the stern rises, rudders lose bite in the water, making steering more difficult, Schuster said.

And losing the front portion of the ship changes the ship’s center of maneuverability, or its “pivot point,” he said.

“That affects how the ship responds to sea and wind effects and changes the ship’s response to rudder and propellor actions,” he said.

The New Orleans’ officers would have had to learn – on the go – a whole new set of actions and commands to keep it stable and moving in the right direction, he said.

The ingenuity and adaptiveness that saved the New Orleans at the Battle of Tassafaronga enabled it to be a force later in the war.

Today was supposed to be the day that President Donald Trump’s so-called “reciprocal” tariffs on dozens of countries kicked in after a three-month delay, absent trade deals. But their introduction has been postponed, again.

The new, August 1 deadline prolongs uncertainty for businesses but also gives America’s trading partners more time to strike trade deals with the United States, avoiding the hefty levies.

Mainstream economists would probably cheer that outcome. Most have long disliked tariffs and can point to research showing they harm the countries that impose them, including the workers and consumers in those economies. And although they also recognize the problems free trade can create, high tariffs are rarely seen as the solution.

Trump’s tariffs so far have not meaningfully boosted US inflation, slowed the economy or hurt jobs growth. Inflation is “the dog that didn’t bark,” Treasury Secretary Scott Bessent likes to say. But economists argue inflation and jobs will have a delayed reaction to tariffs that could start to get ugly toward the end of the year, and that the current calm before the impending storm has provided the administration with a false sense of security.

“The positives (of free trade) outweigh the negatives, even in rich countries,” Antonio Fatas, an economics professor at business school INSEAD, told CNN. “I think in the US, the country has benefited from being open, Europe has benefited from being open.”

Consumers lose out
Tariffs are taxes on imports and their most direct typical effect is to drive up costs for producers and prices for consumers.

Around half of all US imports are purchases of so-called intermediate products, needed to make finished American goods, according to data from the Organisation for Economic Co-operation and Development.

“If you look at a Boeing aircraft, or an automobile manufactured in the US or Canada… it’s really internationally sourced,” Doug Irwin, an economics professor at Dartmouth College, said on the EconTalk podcast in May. And when American businesses have to pay more for imported components, it raises their costs, he added.

Likewise, tariffs raise the cost of finished foreign goods for their American importers.

“Then they have to pass that on to consumers in most instances, because they don’t have deep pockets where they can just absorb a 10 or 20 or 30% tariff,” Irwin said.
