Comment Perfect example of sunk cost fallacy... (Score 1) 78

This is a perfect example of sunk cost fallacy... they continue to throw endless good money after bad.

With SpaceX dragon flying flawlessly (and to think Boeing thought they would beat SpaceX with Starliner lol), and NASA now having the Orion space capsule, there is just no place for starliner.

Just cancel this turd and move on. It simply has no reason to exist anymore, and they continue to throw good money after bad.

I think Samsung's had the 100x space zoom since the S20 Ultra? I had the S21 Ultra and now I have the S23 Ultra. It's very cool, I love the zoom (its useable up to 30x, which is 3x digital zoom on the 10x optical zoom camera) but starts to get very pixelated above that. 100x is not very useable.

But I feel it's been pretty obvious to everyone that Samsung is basically faking the moon photo by overlaying it.

Not sure why this is suddenly news now?

Comment Re:Interesting how little storage is needed (Score 1) 160

Actually, it's not impossible at all. The UK grid needs about 3 times the amount of wind and much more solar and 2 terawatts of underground hydrogen storage.

There's enough salt caverns around the UK that can give it that storage, and the hydrogen can be manufactured via electrolysis when the wind and solar is producing too much. It's not very efficient, but renewables are cheap.

It CAN be done.

FYI as of 2021 the UK had 1.3 GW(h) of battery storage on the grid:

I'm not sure what the total storage is now, it's going to be over 1.5 GW(h) with this installation, and probably a lot more. Note that large batteries aren't needed, it's the total battery storage that's important.

The UK grid operator was particularly keen on getting batteries on it, because the HVDC interconnectors to the continent have been unreliable, and they tend to suddenly break with no warning. That has meant that the grid needs to have a couple of gigawatt of spinning reserve instead, particularly spinning overnight, but with enough batteries they can shut most of that down into hot standby.

The last outage the grid had, due to a lightning strike, they didn't quite have enough battery, and that meant they had to do load shedding and that caused chaos. They should have enough battery now to keep it up long enough if there's a repeat to get backup power running and avoid any load shedding.

The other thing these batteries can do is help smooth out the production curve. If we had enough batteries to smooth out the evening power demand, the CCGT gas turbines would be much more efficient. When they first start up they use about twice as much fuel per kWh until the second cycle kicks in. If they start up less, costs should go down. But we'd need a lot more batteries to make that work.

Submission + - Slashdot Alum Samzenpus's Fractured Veil Hits Kickstarter

CmdrTaco writes: Long time Slashdot readers remember Samzenpus,who posted over 17,000 stories here, sadly crushing my record in the process! What you might NOT know is that he was frequently the Dungeon Master for D&D campaigns played by the original Slashdot crew, and for the last few years he has been applying these skills with fellow Slashdot editorial alum Chris DiBona to a Survival game called Fractured Veil. It's set in a post apocalyptic Hawaii with a huge world based on real map data to explore, as well as careful balance between PVP & PVE. I figured a lot of our old friends would love to help them meet their kickstarter goal and then help us build bases and murder monsters! The game is turning into something pretty great and I'm excited to see it in the wild!

Comment Re: Canada vs. Texas (Score 1) 275

No, there is apparently still one AC tie switch in Dayton, Texas that has been used only once in its history (after Hurricane Ike).

You're right, they do have to synchronize before they connect, but it's not usually a monumental task.

Amusingly the UK national grid was first connected up by technicians playing around in the night without any permission, they just synched up the regional grids that there were at the time and closed the switches- just to see what would happen, as you do! Worked fine, and the following year it was done permanently.

I think it was more that he was blatantly lying about it, not that it was renewables per se.

That, and the plain fact that the failures were very avoidable, that similar conditions had happened before both in Texas and elsewhere, and that the recommendations were simply not followed, meant that it was never going to look good for them.
