You might not need to do work to compress it, but that would mean you expend more energy generating it. That bill still needs to be paid.

His posting style got him banned the first time. There’s a good chance it would have happened again.

Really? Where?

If electricity is more expensive than natural gas, what is the economic incentive of moving to hydrogen, even at a 20% mix? Hydrogen isn't going to be cheaper than the electricity that generates it. How is your electricity generated?

Back to the topic of the OP - these sci-fi shows tend not to depict realistic science/technology or exploration scenarios, so I have to wonder how they would generate excitement for that. It just seems like it would be a letdown to realize the parts that are made up aren’t possible in the foreseeable future or possibly ever.

Terminator didn’t really talk about the dangers of AI. It used that as the plot device to launch an action film in a sci-fi setting.

Hydrogen is not a power source. It’s a storage medium. Hydrogen technology is akin to battery technology. Hydrogen can only be as green as the power that creates it.

Both We have ample evidence that trickle-down doesn’t work, because only a fraction of the money trickles down. And ramping up taxes on the rich isn’t going to stop them buying their shiny pebbles, etc.

It’s not the couple of million spent on the yacht. It’s the many more millions not spent on anything at all. In the hands of the lower echelons of the economy, that money gets spent. Tax from that money gets spent.

The other side of this coin is that people are telling them not to trust, and to not get the vaccine…but the people at the top of the pyramid are vaccinated. It’s interesting seeing the shock of the drones at finding out e.g. FOX news has a vaccine mandate. It’s related to having authoritarians and grifters in power, and the way to show loyalty is to believe what they tell you rather than what you see with your lying eyes. It’s the price of belonging to the tribe.

Only in a rough sense; fission and particle ejection are classified as different reactions. Particle ejection can be endothermic, so you need an energetic particle to cause the proton to be removed. Almost certainly required if you eject more than one. Fissionable materials are typically very heavy nuclei, and fissile materials are a small subset. Particle ejection candidates are found over almost the whole range of the periodic table.

Your terminology is off. You can’t “remove an atom” as you describe. An atom consists of neutrons and protons. The number of protons tells you what element the atom is. You can add or remove protons and you will end up with a new element.

Nobody was “put in a position” You keep framing this as if they couldn’t have said “no thanks” It was their choice. You can question their level of foolishness for going, but you can’t actually gauge that unless you know what situations exist where a fully-trained astronaut would make a difference As far as training goes, at least some of that is so they know what to expect while pulling g’s during launch and while weightless so they’re not experiencing that for the first time on the trip. Someone having a panic attack in close quarters can be a dangerous situation. Also things like the need to sleep near air vents because CO2 buildup can be dangerous because you aren’t moving. As beecee’s link makes clear, NASA is not involved and the flight is 100% privately funded

But nobody was “sent” Part of the issue here is the framing of the situation. Part of it is the claim that a professional would make a difference without any concrete evidence or relevant examples being presented. (Also: Everyone could simply drop the OT nonsense. Regardless of who started it, several people have perpetuated it. It takes two to tango, as it were. It’s not like the original throwaway comment was repeated until others responded, escalating the situation)

Only if there were actions they could take that would do something. Other than 50+ years of experience and advances in technology

But we’re dealing with the ones who would not. It’s not like these people are doing this against their will. Presumably they are properly informed of the risks. The question is what events on a flight like this requires expert human intervention, and what is the risk of those things happening? And what events would an astronaut be able to recover from? But you’re not on the flight.

I don't think that answers the question

They had already solved it, so it's all good

That was not your claim. You said "The square of speed is the gravitational potential." with no caveats.
