  1. "A fusion reactor must first heat hydrogen to temperatures hotter than the sun, turning it into plasma, the fourth state of matter. Then it needs to hold this violent plasma together for long enough that the atoms fuse and disgorge energy. China, the United States and other countries are now racing to develop the machines that can pull all this off and survive to do it again and again, reliably enough to power a grid.

    The world’s two superpowers are in a tightening contest to dominate the energy future. Under the Trump administration, the U.S. is intent on producing oil, gas and coal and selling it abroad. Its chief economic rival, China, has become the world’s dominant supplier of clean energy in the form of solar panels, batteries and electric vehicles.

    Fusion could change the calculus for both nations and the globe. Whoever conquers it could build plants around the world and forge new alliances with energy-hungry countries. But the Americans and the Chinese have very different strategies for getting there.

    The United States is counting on private industry and American innovation to deliver results, with government agencies providing targeted support. From coast to coast, a fleet of start-ups has brought new urgency and ingenuity to the quest.

    On the other side of the world, China’s government has made fusion a national priority, marshaling resources at daunting speed. Recently, a Shanghai start-up essentially matched an engineering breakthrough by America’s best-funded fusion company, Commonwealth Fusion Systems, in much less time. Over the summer, the Chinese government and private investors poured $2.1 billion into a new state-owned fusion company. That investment alone is two and a half times the U.S. Energy Department’s annual fusion budget."

  2. 🦄 Behold, the modern-day alchemists! Marathon Fusion hilariously claims they've cracked the age-old quest for gold with their magical fusion reactors. 🤡 Apparently, they forgot that turning lead into gold is more believable than their #economics. 💸

    It's not only climate change. 😵

    #FusionReactors won't save us.
    #ElectricVehicles won't save us.
    Technology won't save us.

    We need #degrowth. Now.

    At the atomic level, #NuclearFusion in a reactor is identical to the nuclear fusion process that powers the sun, so when the 1st generation #FusionReactors start coming online in the next decade or so, I wonder if people will call them "#SolarPowered."

    I mean, they wouldn't be right, but they wouldn't exactly be wrong, either. 🤔
