A while back I mentioned the SPARC fusion reactor, a relatively new design. What about more traditional approaches to fusion? Here’s a good article about the state of funding for these in the US:
• Adrian Cho, U.S. physicists rally around ambitious plan to build fusion power plant, Science, 8 December 2020.
Here’s the start:
U.S. fusion scientists, notorious for squabbling over which projects to fund with their field’s limited budget, have coalesced around an audacious goal. A 10-year plan presented last week to the federal Fusion Energy Sciences Advisory Committee is the first since the community tried to formulate such a road map in 2014 and failed spectacularly. It calls for the Department of Energy (DOE), the main sponsor of U.S. fusion research, to prepare to build a prototype power plant in the 2040s that would produce carbon-free electricity by harnessing the nuclear process that powers the Sun.
The plan formalizes a goal set out 2 years ago by the National Academies of Sciences, Engineering, and Medicine and embraced in a March report from a 15-month-long fusion community planning process. It also represents a subtle but crucial shift from the basic research that officials in DOE’s Office of Science have favored. “The community urgently wants to move forward with fusion on a time scale that can impact climate change,” says Troy Carter, a fusion physicist at the University of California, Los Angeles, who chaired the planning committee. “We have to get started.”
Impact climate change… with a prototype in the 2040s? Don’t hurry yourselves too much, folks! But you might want to read this:
• Coral Davenport, Major climate report describes a strong risk of crisis as early as 2040, New York Times, 2018 October 7.
INCHEON, South Korea — A landmark report from the United Nations’ scientific panel on climate change paints a far more dire picture of the immediate consequences of climate change than previously thought and says that avoiding the damage requires transforming the world economy at a speed and scale that has “no documented historic precedent.”
The report, issued on Monday by the Intergovernmental Panel on Climate Change, a group of scientists convened by the United Nations to guide world leaders, describes a world of worsening food shortages and wildfires, and a mass die-off of coral reefs as soon as 2040—a period well within the lifetime of much of the global population.
