Why is there always at least one European in these threads misunderstanding how North American power works?

Instructions unclear, all is corn now.
The music of Holst's "The Planets", if we want to complete our list of things Star Wars superficially plagiarized.
AI might be the one to say "solving global warming needs a drastic reduction car-based infrastructure, plus heavy government regulation and investment in new infrastructure". They'll throw out that answer because it isn't what they wanted to hear.
Which this very story proves. The AI voice that they generated was specifically based on "Her", a movie about a guy who falls in love with an AI voice assistant. I haven't seen the movie, but I'm going out on a limb to guess this is another "don't make the torment vortex" situation.
CNC can be done ethically, but it requires very careful negotiations and setup. I've heard of CNC orgies with mandatory classes for everyone. If I had a partner who wanted it, that level of setup is about the only way I'd agree.
Doesn't sound like they're doing anything close to that.
An invasion would be incredibly costly, and would accomplish . . . what exactly? A final resolution to a civil war that barely anyone has a living memory of?
China wants TSMC. Rigging the whole thing to blow in the event of an invasion, and making it very public and very obvious that this is what will happen and cannot be stopped, is the best strategy to avoid that invasion.
Then we have to ask about alternatives. French TGV trains output about 10MW, and can carry over 600 passengers. Three of the solar arrays for these hypothetical green Hindenburgs would run one train, and you're not stuck with shitty thin film panels. The trains will move twice as many people.
If we're talking cargo trains, those max out around 3MW, so just one of these solar Hindenburgs. They will carry far, far more cargo.
Things like propeller efficiency also apply to airplanes.
So we're still stuck where things were going when Hindenburg burned away. Other things were surpassing it, they also improved in the time since, and there isn't much point beyond novelty.
Hindenburg used 4x 735kW diesel engines which need to be powered constantly (almost 3MW overall). That is the output at the shaft, which means we need electric motors that match that. Fortunately, electric motors are pretty efficient.
Thin-film can do 80-120W per m^2. That's the rating when the sun is shining directly on them. We'll assume it's flying above the cloud layer and don't need to worry about that.
At the top end, it will take 24,500m^2 of panels. Hindenburg had a length of 245.3m and diameter of 41.2m. If it were a cylinder (because I don't feel like doing the math on its actual shape), it would have a surface area of 35,000m^2, but that includes the underside. It'll probably pick up some power being reflected off the clouds or the earth's surface, but you're probably only getting 60% of the full power averaged over the entire surface.
Which is closer than I thought it would be, but not quite enough to power the motors if they were 100% efficient, and dropping it to the real world 85-90% won't help. Neither will accounting for its actual shape.
There are plenty of other options that don't burn kerosene.
It wouldn't be light enough. Panels weight about 19kg each for a 1x1.7m panel. This can probably be slimmed down for the application, but probably not by enough. Perovskite promises a lighter weight panel, but they still have longevity issues that are being worked out in the lab.
Why not put those panels on a boat instead? Or in a field and power a train?
Historically, Google had a give-and-take with SEO. You can't make SEO companies go away, but you can curb the worst behavior. Google used to punish bad behavior with a poor listing, and you had to do some work to get it back into compliance and tell Google it's fixed up.
It wasn't ideal, but it functioned well enough.
The drive to make search more profitable over the past few years seems to have meant dropping this. SEO companies can get away with whatever. If they now have the whole manual, game over. Google of a decade ago might have done something about it. Google of today won't bother.
