Brine battery

Looking at the data, energy density is 80ish Wh/Kg for the first

Where can I purchase one?

Wait for it to be in the shops!

I was reading this about Chinese batteries a few days ago:

So, looking for investors? ;-)

In general, over time, about every week a better battery is announced...

In reality the same old ones are still in the shops.... OK, I have nice lifePo4 12 V 250 Ah plus 2 kW pure sine wave 12 V to 230 V 50 Hz converter

I'd be curious about the long-term stability as well, since corrosion and electrode degradation are usually the biggest challenges with saltwater or brine-based cells. It would be interesting to see some real-world cycle life data rather than just the initial performance.

Hina?

Interesting that western 'research' is limited to tearing down physically delivered chinese product.

It's unlikely to be limited to that. Tearing down competitors gear is a necessary part of being competitive (in a high volume market - its not something I've ever been involved in), but you don't expect to find out anything all that useful. Various manufacture's production lines differ, and the differences between products tend to reflect more about the differences in the production lines than anything all that exciting.

Yes, Chinese are way ahead in some stuff I have a Huawei modem 4G USB stick to go online anywhere, and a Xiaomi smartphone. Lots and lots of made in China electronic modules. GPS stuff, flashlights, what not. LCDs OLEDs all sort of sensors But they put tariffs on it here on ebay these days..

I do think (keep it quiet ;-)) that China will soon have a re-usable rocket like Musk has. And then the whole world will move to China to have their space stuff launched. Musk knows that,. so he decided to cash in before it is all over for him.

China doesn't invent much nowadays. They mostly copy and apply a lot of cheap labor and polluting process.

Nothing new there. Industrialized nations have always spied on each other. China is just a relative newcomer with some original ideas.

You are conditioned by your propaganda machine. China is well on its way to become a technological super power. You'd better get rid of the idiots in the white house and get back to work.

Not you personally, I mean, but as a nation.

Jeroen Belleman

The US is still inventing things. I see a lot of that going on.

China's big problem is its young people. They don't have many, and the ones that they have are fairly unemployed, and not dating or making babies.

Their birth rate is less than half of replacement.

I don't need a propaganda machine to see all that.

The furriners coming here for the World Cup don't either. The USA rocks.

John Larkin is behind the times. China, like Japan, and earlier, America has been through the process of modernising their technology on the basis of stuff developed elsewhere (in America's case, Europe).

China has got through the copying phase, and after sending a lot of students to oversea universities, is doing it's own innovation.

It's society - like America's - isn't well adapted to encouraging creative research. It's heirarchical - like America - through the heirarchy is based on political power rather than money, but if you have enough ingenious engineers you can still get stuff invented if you keep trying for long enough.

No advanced industrial society has a local birth rate that would sustain the existing population level.

Once we stopped having half our children die of infectious diseases before they got old enough to reproduce. our populations went up rapldly, and over-shot. The correction is now in progress.

You do need to understand a bit more to make senses of it.

It knows how to spend money to give visitors a good time. It's less willing to spend money on keeping the resident population content, which is why they vote for an irresponsible impulsive ignoramus like Donald Trump. He promised to break the system, and he's delivering to the extent that he can.

A gradual decline of the world's population in happening, and it's good. But a population that's falling off a cliff, half of replacement rate, causes big problems.

The visiors are spending the money.

Which are probably solvable. Human beings last seventy years - more than eighty years in advanced industrial countries - so the decline in population isn't all that rapid.

Lured in by events that the locals had to spend money to set up.

It's a money-making business. There can be an element of altruism in doing it right, but when it happens on an industrial scale one has to suspect that somebody is making a lot of money out of it.

Open your eyes.

It's in the application that most useful 'invention' occurs, by accident and observation.

Brine batteries could make the whole alternate energy infrastructure increasingly eco-friendly and resource war immune.

Ticket pricing for the FIFA 2026 cup is complicated and variable. The average appears to be in $500 ballpark, but it varies widely depending on the view from the seat, the level of the match and the contenders. With a stadium of about 80k seats, that's 40 M$ for a single match right there. There are 104 matches. Then there are the TV broadcasting rights, about 3.9 G$ globally, I gather.

Yes, football is big business. Well, except for the likes of DJT, who get to rip off a whole country and then some.
