This ain't gonna work for FPS games... ping times of 25 minutes!

More seriously, I wonder what sort of protocol they're using. I guess they could just use standard protocols, but with a freaking huge ACK window, but it seems more likely they'd use extensive FEC to reduce effective bit errors to extremely low rates, since NAKing and retransmitting corrupted packets would be incredibly slow. Or maybe that's okay. As long as they're only transmitting stored data which can be retransmitted a half hour later if needed, it might be fine to use simple error detection with retries. Dunno. This would be a fascinating problem to solve.

The increase I'm talking about is just in deployed capacity... it's a manufacturing and installation problem, not a technology problem, and it's manufacturing and installation (as well as demand) that is doubling deployed capacity every year, not technological changes. If you want to claim that the current rate of growth is going to stop it's incumbent on you to explain why it will change.

That said, I think you're wrong that the technology is "done". There is lots of very interesting research going on, in both new chemistries and in new manufacturing techniques.

To buffer a single day in the US you need 261x the GLOBAL capacity added in 2023. To effectively electrify society you will at least have to double that again.

Sure. So? 10 years is almost certainly not enough to get us to that capacity, but 20 years is. Like most such things, installed battery capacity is likely following a sigmoid curve, and we're in the exponential phase, with an exponent of around 2. Assuming we didn't level off, 20 years would see global installed capacity increase about 1,000,000X.

Now please drop me a link for an affordable powerwall alternative

Define "affordable". There certainly are plenty of Powerwall alternatives that are less expensive than Tesla's.

But that's not really the point of the article. The point is that battery prices have been dropping rapidly for a couple of decades now, and they're showing no sign of slowing. The point is that the cheaper batteries that will be available in the next 1-2 decades will make renewables cost effective as a full replacement for fossil fuels.

a replacement battery for my EV after its supposedly "immortal" battery dies after 5 years of use

If your battery dies after five years, it will be replaced for free under warranty because it's faulty. AFAICT all the manufacturer warranties are around 8 years.

However, it's really unlikely to happen. My 2011 Nissan Leaf's battery is still fine, though it only has about 80% of its original capacity, and the Leaf is about the worst case scenario since Nissan failed to implement thermal management. My four year-old Tesla still has 95% of its capacity.
