The article is a bit skimpy on details and the curves really simplistic – well it's log scale – but the conclusion I can see, even if fusion power plants would work, they probably won't be cost effective soon.

"Just because we can" is sometimes enough reason for what otherwise looks like pointless activity (BASE jumping, NFL football, sudoku, putting boots on the moon with no clearly defined purpose etc.) but when it comes to actual utility, why we think creating our own sun-in-a-bottle is better than using the actual freely gifted fusion reactor we already have continues to mystify me. The trade for any gain is starkly lopsided.

Openstar hit another step on their development. Nice one. Fusions now only 9 1/2 years away ;-)
They'd better have some good de-greaser given how many politicians they had on site. It would be handy if they had a nuclear incinerator handy....

Weekly output: FCC independence, Starlink mobile-broadband ambitions, TAE + TMTG, best WiFi hotspots
In addition to wrapping up my holiday shopping far later than I expected, this week saw me mostly finish migrating from Evernote to Obsidian after management at the note-taking app I’ve used since 2010 elected to impose a 92 percent rate increase.
12/18/2025: FCC Scrambles to Edit Website After Chair Refuses to Say Agency Is Independent, PCMag
Here we have yet another case of the 2025 version of FCC chair Brendan Carr taking a position on a tech-policy issue explicitly rejected by an earlier model year of this man. But this time around, the Trump-loyalist chairman made his heel turn even more obvious by apparently ordering up a hasty edit of the commission’s about-us page.
12/19/2025: SpaceX Exec Tips ‘Real’ High-Speed Cellular Starlink, With 15K More Satellites, PCMag
This story started with my attending a space-telecom conference in D.C. two Mondays ago, then I needed to educate myself much more about SpaceX’s ambitions for direct-to-device broadband from a future generation of Starlink satellites.
12/19/2025: Trump’s Truth Social to Merge With Fusion Startup You’ve Probably Never Heard Of, PCMag
Will the Trump family still be so enthusiastic about TAE Technologies if their backing somehow helps it finally commercialize fusion power generation and in so doing hammers the last nail into the coffin of the coal-fired power plants so beloved by our scientifically-illiterate president? (Answer: That question is probably irrelevant, because coal is already so uncompetitive that this administration’s fossil-fuel fetishists feel compelled to issue orders to keep obsolete coal plants online on a fake “emergency” basis.)
12/19/2025: The Best Wi-Fi Hotspot, Wirecutter
I updated the “What to look forward to” section of this guide–last updated almost a year ago–to note how AT&T has added two newer models to its lineup. One of them looks like an immense improvement over our previous pick from that carrier.

The future of energy policy just got a reboot! Trump's Energy Department is reshuffling, reportedly ditching renewables for a laser focus on fusion. This bold move, cutting congressionally authorized offices, is set to spark legal challenges. Strategic pivot or risky bet?

Google DeepMind is teaming up with a fusion energy startup, not just as a power supplier, but potentially as a customer. Because apparently, solving the world's energy crisis is just another Tuesday. Are they going to run their data centers on mini-suns next? What's the wildest AI application you can imagine for energy?

#ElonMusk and his *newly government approved* #grok solving the scientific riddle of #fusionpower first, even while still needing all that midwest #methane to do it, would then get him to Mars if he wants, and also make him an Earth-saving superhero where #climatechange is concerned.
Or even this, if it must:

the desire to tech-fix structural problems is so depressing.
I get it. Scientists are nerds, and if you have the luck that your field of research receives billions of funding, who are you to say no?But the policy makers responsible for the allocation of these funds... don't these people, like... inform themselves?
Even IF fusion reactors could be developed in a reasonable timespan (and the billions required for research would not just diverti much needed investments into clean and decentralized energy):
A lot of energy is by no means a solution to the transgression of the multiple planetary boundaries (nor does it help against the rise of fascism we are experiencing).
So, I let you here with this nice figure, you all can draw your own conclusions.

Creating a new path forward for compact fusion vessels. New research suggests plasma inside a tokamak reactor can be sufficiently heated using only microwaves. Eliminating the central ohmic heating coil normally used, will free up much-needed space for a more compact, efficient spherical reactor. #science #physics #fusion #plasma #FusionPower #engineering #powergeneration #environment https://www.sciencedaily.com/releases/2024/08/240806131216.htm

We'd have a cure for Cancer and Fusion Power by now were it not for Late Stage Capitalism, I'm sure of it.
Both would make some very rich people slightly less rich, so they don't happen.
Coin rules over all. Short term gain for long term pain. -
Logic -- good logic -- would dictate that the absolute first problem #AI needs to solve is the issue of radically cheaper #powergeneration : lower transmission loss, and for heavens sake, sort out #FUSIONpower -- *first*.

@euronews @climate-crisis-euronews Extracted from Bulletin of Atomic Scientists..”A long-recognized drawback of fusion energy is neutron radiation damage to exposed materials, causing swelling, embrittlement and fatigue. As it happens, the total operating time at high neutron production rates in ITER will be too small to cause even minor damage to structural integrity, but neutron interactions will still create dangerous radioactivity in all exposed reactor components, eventually producing a staggering 30,000 tons of radioactive waste……For the much smaller Joint European Torus experimental project in the United Kingdom, the radioactive waste volume is estimated at 3,000 cubic meters, and the decommissioning cost will exceed $300 million, according to the Financial Times. Those numbers will be dwarfed by ITER’s 30,000 tons of radioactive wastes. Fortunately, most of this induced radioactivity will decay in decades, but after 100 years some 6,000 tons will still be dangerously radioactive and require disposal in a repository, says the “Waste and Decommissioning” section of ITER’s Final Design Report…”
