That's some nice shaping on the panels! Is it carbon fiber?

Israeli Government Has Spent $8.6M on Campaign to Influence US, European Policy ( truthout.org )

A report by The Guardian released Monday reveals that the same group behind a covert Israeli social media campaign to influence U.S. politicians has also spent months coordinating with dark money groups, Israel advocacy organizations and lawmakers to spread pro-Israel sentiment between 80 different ongoing programs. The campaign...

JohnDClay ,

Yeah, given campaign costs in the US at least, that is really tiny money.

It'd need to be 13 to 80 times more massive to be a brown dwarf.

https://en.m.wikipedia.org/wiki/Brown_dwarf

If it gained mass rapidly, most all the moons would likely destabilize since they'd have way too little velocity for the orbit they'd now be in. But if they sped up to accommodate, it'd depend on the density change of Jupiter. The fusion would push out material a bit, but the density would probably just increase because of the increased mass.

But if the density stayed the same, the radius would be 2.4 to 4.3 times larger than currently. With Jupiter having a radius of 70,000 km, that'd put it at 170,000 to 300,000 km radius. That'd put Metis and Adrastea inside 170, and Amalthea and Thebe inside 300. They'd already be heavily inside the jovian atmosphere, so they'd be toast. Io, Europa, and maybe others might also fall due to higher atmospheric drag at those levels.

I think the rest of the moons would be planets then, and the solar system would be a binary system.

Median income or ihdi are much better indicators of people's well-being.

The economy/gdp is just a measure of how much stuff you are making, not who is getting it.

Interesting, I thought this would be about using algae for kerosene synthesis, but it looks like they're getting electricity from it like a solar panel. I wonder what the area efficiency is vs a solar panel, and if it might have advantages in cost or longevity.

SpaceX has been receptive to design changes to starlink in the past to minimize impact, like decreasing reflectivity and reflection angles for astronomers. They might be receptive to moving to different alloy for the body construction.

Magnesium comes to mind that would be light but expensive. Steel alloys might be cheap and heavy options for later when starship is operational. Would those have similar effects on ozone, or is it only the aluminum oxides?

JohnDClay ,

They allowed to attack military targets in internationally recognized Russia yet? Permission to do that would really help undermine logistics and concentrations.

JohnDClay ,

It's also common for governments to say their spy sats failed so that it's more ambiguous what assets they have. I don't know if someone has a telescope tracking shot though, that could probably confirm or deny.

JohnDClay ,

Those two are the same place? Looks like it was entirely destroyed and rebuilt as something else, I'm seeing very little similarly between the two.

JohnDClay ,

I don't understand how the event horizon booms to be so large compared to it's mass. And does a black hole suddenly pop into existence when that density is reached, or does it need to collapse or have some condensed distribution?

JohnDClay ,

Yeah I get that. But the video was saying a black hole the diameter of the solar system has an average density inside the event horizon of air. I was wondering if you need to compress it any, or if a solar system sized volume of air would already be a black hole, or would it need to collapse to a singularity first?

What Putin is doing is horrible to both sides. He's killing a whole generation.

But also, defecting is an option. So I didn't need to feel too bad for Russian soldiers being killed since they should have surrendered or refused to fight in Putins war.

JohnDClay ,

Better to die than to kill wrongly. But I have seen lots of videos of Russians successfully surrendering, so it's definitely an option.

JohnDClay ,

I agree it'd be hard. But it'd still be the right thing to do to avoid murdering people. I don't see how I need to have been in that situation to say that moral statement. I hope I'd be able to follow though.

JohnDClay ,

For the things the money buys. Because it's really though to trade food directly for them.

JohnDClay ,

The ability to purchase items you want with money gives it value.

JohnDClay ,

Is this installed capacity, or actual power output? If installed capacity, you'll need a lot more than 100% since that's just the nameplate max capacity, not the average. I'm glad we've gotten this far, but we still need to transition to 100% or more very soon.

JohnDClay ,

The trend line looks good though, we've been mostly maxed out on hydropower for decades.

JohnDClay ,

Cool. I guess I was thinking in the US. Globally is still getting more

JohnDClay ,

Pulling the fuse that includes OnStar at least keeps it from calling home. But there's usually some collateral damage.

JohnDClay ,

My car microphone stopped working

JohnDClay ,

I think my car only came with a free trial for that service, I think you needed to pay after a certain amount of time. Cell phone works well enough for me.

JohnDClay ,

I estimate that the probability of injuring my arms and that no one else is around to call for help is low enough to not be worth the monthly subscription.

JohnDClay ,

I judge based on probability and severity, and the probability is small enough even though the severity is high for me to not be concerned.

JohnDClay ,

Okay... You seem needlessly confrontational...

JohnDClay ,

Boeing makes jdam bombs, that would put them up there.

JohnDClay ,

Defense of Ukraine is a great example of how weapons can be used for good. But definitely not all that these companies do, as Gaza shows.

JohnDClay ,

Lol no

JohnDClay ,

Localizing is really hard because of corruption. It's easier to say where all the money is going when you do the whole thing.

Is the drive to localize to improve indigenous capabilities? Or would you get more bang for the buck? Or does it produce better outcomes?

Russia threatens Britain with retaliation if involvement in Ukraine war deepens ( www.pbs.org )

Russia on Monday threatened to strike British military facilities and said it would hold drills simulating the use of battlefield nuclear weapons amid sharply rising tensions over comments by senior Western officials about possibly deeper involvement in the war in Ukraine....

JohnDClay ,

Like they've been threatening for the last two years? They're out of escalation options that are useful for them.

JohnDClay ,

Wait till we find one based on steel's phase changes!

North Korean weapons are killing Ukrainians. The implications are far bigger ( www.bbc.com )

On 2 January, a young Ukrainian weapons inspector, Khrystyna Kimachuk, got word that an unusual-looking missile had crashed into a building in the city of Kharkiv. She began calling her contacts in the Ukrainian military, desperate to get her hands on it. Within a week, she had the mangled debris splayed out in front of her at a...

JohnDClay ,

Ukraine is a proxy war for North and South Korea?

JohnDClay ,

Idk, not many places trade with NK. China then?

JohnDClay ,

Probably something like 'I've gotta pee'

JohnDClay ,

I think Lemmy strips it, right? That's why pictures were uploading sideways for a while?

JohnDClay ,

Desalination is also a good way of getting lithium right now, it's just a bit less cost effective than surface mining dried oceans currently. Maybe if sodium demand also goes up, it'll be effective to capture desalination salts for both lithium and sodium.

Where do you live that it's often -30? And if you need to drive 300mi to a doctor's for a medical emergency at that one time if year, do you have someone else you could ask or only drive there and worrying about charging later?

JohnDClay ,

100+ miles is fine for most any EV. My bolt during the winter was still able to get 200mi+ at 70mph in sub zero F weather. With a home charger it's fine. It's road trips that would push further. I've found charging adds maybe 25% time to long trips. But that doesn't seem to be the use case you're referring to.

JohnDClay ,

We didn't know which things mechanisms in a nuron are important, and we don't have anywhere near the computing power to model all of them. We have guesses as to what's important, and that's what a lot of modern AI is built on. But because computers have different strengths and weaknesses, we can't simulate a whole human brain yet.
