Submission + - Idaho Lab Produces World's First Molten Salt Fuel For Nuclear Reactors (cowboystatedaily.com)

Submitted by schwit1
schwit1 writes: The U.S. Department of Energy Office of Nuclear Energy announced this week that researchers at INL have successfully created the first batch of fuel salt.

Fuel salt is a molten salt mixture used as both a carrier for nuclear fuel and coolant in a molten salt reactor, a type of advanced nuclear reactor.

The fuel salt is critical for conducting the world’s first fast-spectrum, salt-fueled reactor test, known as the Molten Chloride Reactor Experiment (MCRE).

The test will help inform the future commercial deployment of a new class of advanced nuclear reactors, something a number of Wyoming-connected companies are proposing to build.

“There is a lot of push for this,” said James King, project lead for the Molten Chloride Experiment at INL. “We need to have a lot of different options so we can move away from less safe power generations methods.

“This is one of those technologies that can move us to better safety.”

The liquid form of the salt fuel means the fuel can’t melt. The technology would also offer another low-carbon alternative to generating power.

Submission + - USA will bar visa applicants who combat disinformation (npr.org)

Submitted by ClickOnThis
ClickOnThis writes: The Trump administration wants to bar visa applicants who combat disinformation and hate speech from entering the USA on work visas, on the grounds that they practice 'censorship.' From the article:

The directive, sent in an internal memo on Tuesday, is focused on applicants for H-1B visas for highly skilled workers, which are frequently used by tech companies, among other sectors. The memo was first reported by Reuters; NPR also obtained a copy.

"If you uncover evidence an applicant was responsible for, or complicit in, censorship or attempted censorship of protected expression in the United States, you should pursue a finding that the applicant is ineligible" for a visa, the memo says. It refers to a policy announced by Secretary of State Marco Rubio in May restricting visas from being issued to "foreign officials and persons who are complicit in censoring Americans."

My insurance keeps going up because private insurance in America has a monopoly on access to healthcare so they can charge whatever they want until the public gets so fed up they demand a single pair of healthcare system.

If things continue the way they're going with voter suppression and right wing extremists buying up the voting machine companies I don't think it'll matter anymore and then that will be the end of that. About 10% of the country will be allowed to have health care and odds are you won't be in it.

The current "AI" is a predictive engine.

And *you* are a predictive engine as well; prediction is where the error metric for learning comes from. (I removed the word "search" from both because neither work by "search". Neither you nor LLMs are databases)

It looks at something and analyzes what it thinks the result should be.

And that's not AI why?

AI is, and has always been, the field of tasks that are traditionally hard for computers but easy for humans. There is no question that these are a massive leap forward in AI, as it has always been defined.

It is absolutely crazy that we are all very very soon going to lose access to electricity

Calm down. Total AI power consumption (all forms of AL, both training and inference) for 2025 will be in the ballpark of 50-60TWh. Video gaming consumes about 350TWh/year, and growing. The world consumes ~25000 TWh/yr in electricity. And electricity is only 1/5th of global energy consumption.

AI datacentres are certainly a big deal to the local grid where they're located - in the same way that any major industry is a big deal where it's located. But "big at a local scale" is not the same thing as "big at a global scale." Just across the fjord from me there's an aluminum smelter that uses half a gigawatt of power. Such is industry.

Most of these new AI tools have gained their new levels of performance by incorporating Transformers in some form or another, in part or in whole. Transformers is the backend of LLMs.

Even in cases where Transformers isn't used these days, often it's imitated. For example, the top leaderboards in vision models are a mix of ViTs (Vision Transformers) and hybrids (CNN + transformers), but there are still some "pure CNNs" that are high up. But the best performing "pure CNNs" these days use techniques modeled after what Transformers is doing, e.g. filtering data with an equivalent of attention and the like.

The simple fact is that what enabled LLMs is enabling most of this other stuff too.
