| A nuclear fusion power plant prototype is already being built outside Boston. How long until unlimited clean energy is real?
<a href=https://www.e1.ru/text/business/2023/07/15/72500345/>гей член</a>
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.”

AP — At least three people were missing in a mountain village in southern New Mexico that is a popular summer retreat after monsoon rains triggered flash flooding Tuesday that was so intense an entire house was swept downstream.
<a href=https://tripscan.live>tripscan войти</a>
Emergency crews carried out at least 85 swift water rescues in the Ruidoso area, including of people who were trapped in their homes and cars, said Danielle Silva of the New Mexico Department of Homeland Security and Emergency Management.
No deaths were immediately reported, but Silva said the extent of the destruction wouldn’t be known until the water recedes.

“We knew that we were going to have floods … and this one hit us harder than what we were expecting,” Ruidoso Mayor Lynn D. Crawford said during a radio address Tuesday night.
Crawford said that some people were taken to the hospital, although the exact number was not immediately clear. He encouraged residents to call an emergency line if their loved ones or neighbors were missing.
The floods came just days after flash floods in Texas killed over 100 people and left more than 160 people missing.
In New Mexico, officials urged residents to seek higher ground Tuesday afternoon as the waters of the Rio Ruidoso rose nearly 19 feet in a matter of minutes amid heavy rainfall. The National Weather Service issued flood warnings in the area, which was stripped of vegetation by recent wildfires.
A weather service flood gauge and companion video camera showed churning waters of the Rio Ruidoso surge over the river’s banks into surrounding forest. Streets and bridges were closed in response.
Kaitlyn Carpenter, an artist in Ruidoso, was riding her motorcycle through town Tuesday afternoon when the storm started to pick up, and she sought shelter at the riverside Downshift Brewing Company with about 50 other people. She started to film debris rushing down the Rio Ruidoso when she spotted a house float by with a familiar turquoise door. It belonged to the family of one of her best friends.
Her friend’s family was not in the house and is safe, she said.
“I’ve been in that house and have memories in that house, so seeing it come down the river was just pretty heartbreaking,” Carpenter said. “I just couldn’t believe it.”
There were also reports of dead horses near the town’s horse racing track, the mayor said.
Two National Guard rescue teams and several local teams already were in the area when the flooding began, Silva said, and more Guard teams were expected.
The area has been especially vulnerable to flooding since the summer of 2024, when the South Fork and Salt fires raced across tinder-dry forest and destroyed an estimated 1,400 homes and structures. Residents were forced to flee a wall of flames, only to grapple with intense flooding later that summer.

| “It’s true that both plants are not yet operating at the capacity we originally targeted,” said the Climeworks spokesperson.
<a href=https://tripscan.biz>трипскан</a>
“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.”

| More than 200 firefighters are struggling to tackle an out-of-control wildfire on Crete — Greece’s largest island and a tourist hotspot — as authorities order mass evacuations.
<a href=https://tripscan.live>трипскан</a>
The fire broke out Wednesday afternoon near Ierapetra, a town on the island’s southeast coast, amid unusually high temperatures, 3 to 5 degrees Celsius (5.4 to 9 Fahrenheit) above average, and gale-force winds of around 50 miles an hour.
The conditions are creating “new outbreaks, making firefighting work very difficult,” the Fire Department’s press spokesperson, Chief Vasilios Vathrakoyannis, said in a statement Thursday.

More than 230 firefighters, along with 46 vehicles and 10 helicopters have been deployed to fight the blaze, according to fire officials.
The flames have spread rapidly, reaching homes as well as hotels and other tourist accommodations.
Authorities asked residents of four settlements to evacuate and move toward Ierapetra. About 1,500 people have been evacuated so far, according to the Greek public broadcaster ERT.
The Ierapetra municipality has converted an indoor training center facility into a makeshift camp, where hundreds of tourists and residents who abandoned their homes spent the night Wednesday.
The police, medical services and the coast guard have all been called to the area.
“We are entering the third and most difficult month of the fire season,” Vathrakoyannis said. July is typically the hottest month in Greece and is often accompanied by strong winds. “These conditions favor the spread of fires and increase their danger,” he said.
Wildfires have ripped through other European countries this week as the continent endures a brutal heat wave.
Tens of thousands were evacuated in Turkey as blazes ripped through the western Izmir and Manisa provinces and southern Hatay province, damaging nearly 200 homes.
Blazes also broke out in France and in Spain, where two people died.
Europe experiences wildfires every year, but they are becoming more intense and frequent due to human-caused climate change, which fuels heat and drought, both helping set the stage for fierce, destructive fires.

| Extreme heat is a killer. A recent heat wave shows how much more deadly it’s becoming
<a href=https://tripscan.xyz>tripscan войти</a>
Extreme heat is a killer and its impact is becoming far, far deadlier as the human-caused climate crisis supercharges temperatures, according to a new study, which estimates global warming tripled the number of deaths in the recent European heat wave.
For more than a week, temperatures in many parts of Europe spiked above 100 degrees Fahrenheit. Tourist attractions closed, wildfires ripped through several countries, and people struggled to cope on a continent where air conditioning is rare.

The outcome was deadly. Thousands of people are estimated to have lost their lives, according to a first-of-its-kind rapid analysis study published Wednesday.
A team of researchers, led by Imperial College London and the London School of Hygiene and Tropical Medicine, looked at 10 days of extreme heat between June 23 and July 2 across 12 European cities, including London, Paris, Athens, Madrid and Rome.
They used historical weather data to calculate how intense the heat would have been if humans had not burned fossil fuels and warmed the world by 1.3 degrees Celsius. They found climate change made Europe’s heat wave 1 to 4 degrees Celsius (1.8 to 7.2 Fahrenheit) hotter.
The scientists then used research on the relationship between heat and daily deaths to estimate how many people lost their lives.
They found approximately 2,300 people died during ten days of heat across the 12 cities, around 1,500 more than would have died in a world without climate change. In other words, global heating was responsible for 65% of the total death toll.
“The results show how relatively small increases in the hottest temperatures can trigger huge surges in death,” the study authors wrote.
Heat has a particularly pernicious impact on people with underlying health conditions, such as heart disease, diabetes and respiratory problems.
People over 65 years old were most affected, accounting for 88% of the excess deaths, according to the analysis. But heat can be deadly for anyone. Nearly 200 of the estimated deaths across the 12 cities were among those aged 20 to 65.
Climate change was responsible for the vast majority of heat deaths in some cities. In Madrid, it accounted for about 90% of estimated heat wave deaths, the analysis found.

| Questioned by both Republicans and Democrats on Capitol Hill about the low staffing numbers, Interior Secretary Doug Burgum has brushed off concerns, testifying in May that slightly less than half of permanent NPS employees work on the ground in the parks, while other staff work at regional offices or at DC headquarters.
<a href=https://tripscan.live>трипскан</a>
“I want more people in the parks,” Burgum said. “I want less overhead. There’s an opportunity to have more people working in our parks … and have less people working for the National Park Service.”
https://tripscan.live

But internal NPS data tells a different story, Brengel said, showing that around 80% of National Park Service staff work in the parks. And regional offices play an important supporting staff role, with scientists on staff to help maintain fragile parks ecosystems, as well as specialists who monitor geohazard safety issues like landslides.
Republican Sen. Lisa Murkowski of Alaska recently pressed Burgum to provide a full list of staff positions that have been cut at the National Park Service, Bureau of Land Management and the US Forest Service since the Trump administration took over. The Interior Department has not provided the list, a Senate staffer said.
The regional offices within the park service are on edge, waiting to see how courts rule on a Trump administration reduction in force plan they fear could gut their ranks, a National Park Service employee in a Western state told CNN.
“If they greenlight the RIF plan, then it’s going to be a bloodbath,” the employee said.
In addition to probationary workers that were fired in February, early retirements are also culling the agency’s ranks, and the continued $1 spending limit on federal workers’ credit cards is making it extremely difficult to do field work in the parks, with a simple overnight trip needing to be requested 10 days in advance, the employee added.
The lack of superintendents and NPS supervisors creates more of a headache, they added.
“These times, when it’s all about fighting for scarce resources, you really need those upper-level people with clout working the system,” the employee said.
Hall, the retired NPS regional director, said losing rangers, maintenance professionals and park superintendents could profoundly alter American landmarks.
“What you’ve lost with all this attrition – you’ve lost all this knowledge that’s going to take years to build back up,” Hall said.
