The $15/kWh is misleading as it's only the cost of the raw materials.

The article claims CATL have given bulk cell pricing at 19$/kWh.

That still leaves an Additional overhead due to power electronics and assembly but all in all it's a pretty impressive development.

I was under the impression that lfp didn't work in cold temperatures, which is a problem if you want to keep it in a shed so it doesn't burn your house down.

LFP have a significantly more stable battery chemistry. Much more abuse tolerant and less likely to suffer thermal runaway. You'd get LFP cells so you won't have to store them in the shed due to fire safety. And while sodium ion batteries would be happy in a frozen shed they're supposed to be even more stable.

Anyway,sodium ion taking off explains the recurrent deep sales for LFP power stations. Which might still be overpriced if there developments hold up.

we re going to get closer and closer to removing all hand-engineered features of neural network architecture, and letting a giant all-to-all fully connected network collapse on its own to the appropriate architecture for the data, a true black box.

Which is the Logical conclusion.

If the neural network can distill a model out of complex input data.

Especially when many model are frequently trained through data augmentation practices that actively degrade input to achieve generalisation abilities.

Then why are we stuck wearing silk glove tokenizers?

I followed you until that last bit...

I will elaborate.

A bridge is built upon a solid foundation of something empirically tested, a hard science and good engineering practice if you will. And if not, it will not remain a bridge for long.

The innumerable electronic subcomponents in any of your electronic devices work very well for years. The MTBF is clearly high or it would be dead on arrival or soon afterwards.

We too easily extrapolate this reliability pattern onto the softer sciences, creating a biological mythology with an underpinning built on inherited opinion and untested speculation.

> "My doctor said blood letting will cure my tuberculosis"

> "Less stress and less coffee will cure my stomach ulcers"

> "Keep Peanuts away from my kid until he can legally drink so he won't be allergic to them!"

The romans built bridges that are still bridges 2000 years before any of above quotes went out of style. Whatever kept them alive for so long can be nothing but a weakly described, but very durable and still present dark pattern of the mind and the public discourse.

Nutritional science have unfortunately been pretty bad at the science part for a rather long time.

There's a dark pattern hiding in the modern era where we assume hard evidence to exist where it doesn't, a projection of CAD engineering onto idle theory crafting and opinion.

The Guardian raises tabloid press to a new level of bad taste, posing a serious faced question about stupidity and immediately answers it by having their site drop a blocking full screen emotionally loaded ad-request for my money in the sloppiest way possible. I will assume the content it blocked was AI generated bait and will find a better article to read.

The chart shows a Biden-projected growth of 30GW renewable capacity until 2030.

If these renewables could run at max capacity 24/7 they'd then produce ballpark high estimate 270 TWh.

Looking at the Chinese comparison chart china adds 2000TWh of annual production per 5 year interval.

Now renewables run at 25% capacity factor on a good day, so the renewable growth with bidenomics would've added 65 TWh of growth in a span of time that china adds 2000. If Trump causes a further drawdown of 100 TWh in renewable capacity it will still only be a rounding error.

The US and most of the west is simply not even competing in this arena, the entire leadership is resting on their laurels and the focus is never on actual development but on policy, regulations and ideology.

Edit: I now see it was Paul Krugman as the author of that article which clearly illustrates my point on ideological drive of the western leadership, here we have an economic Nobel Prize winner that present numbers he either don't understand or misuse to take potshots at a leadership he's unhappy with.

Seems like the people denounced as baseless conspiracy theorists were right.

Again.

>nobody seems to want it

I've had a lot of genuine fun playing with AI art generators dating all the way back to deepdream. I love the tech, I want it as it was, as it is, and as it will become. This tech have in the last few years given me much more joy than any artist have come close to. It shares creative powers freely, a far cry from the overly commercial streaks dominating much else.

What I don't want is to see yet another has-been meme artist rehash the same anti-AI tirade that we've seen so frequently that any given LLM could re-create it verbatim due to overfitting.

All talk about "Human originality, soul, heart, the divine spark" and yet all they display is hysteria.

There will always be a realy fucking bad failure mode attached to any energy dense storage medium. This is basic physics. The diffrence between a roaring fire in the wood stove, your car engine, an ultra high tech rocket motor and a bomb, is only the speed of the "flame front" A battery has the same issues, in that the higher the energy density and the greater the expected rate of energy transfer, the greater the chance of finding a way to detonate all the energy at once, which is actualy possible ,with a wood stove, if things go exactly wrong.Exceptionaly large explosions have happened with nothing more than dust, or flour. 4 things, you can pick 3. fast, powerfull, cheap, safe.

A Lithium iron phosphate battery is significantly more stable and less likely to go thermal runaway in a fireshow-like fashion. The battery chemistry is important for this.
