Lo avrete sicuramente notato, navigando su Wikipedia, negli ultimi giorni Jimmy Wales, ideatore dell’enciclopedia libera, sta chiedendo ai visitatori piccole donazioni per Wikimedia Foundation, indispensabili per garantire la sopravvivenza del sito.

Sergey Brin, fondatore di Google insieme a Larry Page, ha donato ben 500.000 dollari, attraverso la sua fondazione Brin Wojcicki Foundation, creata insieme alla moglie Anne Wojcicki.

Non è la prima volta che la fondazione Brin Wojcicki effettua grosse donazioni, qualche anno fa Brin ha versato soldi anche nelle casse della fondazione di Michael J. Fox.

  47. Я искренне верил, что VIP Club станет для меня возможностью изменить жизнь к лучшему. Купил токены, установил мессенджер NON PRY, оплатил доступ к кабинету, но всё оказалось пустышкой. Токены не имеют никакой ценности, а мессенджер постоянно зависает и не выполняет своих функций. Личный кабинет стал недоступен, а поддержка просто игнорирует мои обращения. Это чувство бессилия и разочарования сложно описать словами. Я ожидал честного проекта, а получил обман. Никогда не думал, что стану жертвой такой схемы. Очень тяжело было принять это. Понимаю, что не одинок в этой ситуации. Очень грустно и обидно.

  48. A nuclear fusion power plant prototype is already being built outside Boston. How long until unlimited clean energy is real?

    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.”

  49. “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.”
