It likely means demolishing a lot of existing houses and businesses to make room for the train

It doesn't. What it means is cutting through a lot of big parcels whose owners have big money, so they can be big impediments. There has to be a happier medium than this between respect for individual private property ownership and the needs of the many, but we are clearly uninterested in finding it in this country.

Windows 11 users can add native support through an image extension from Microsoft Store

That's not what "native" means.

Who invented pluggable file formats anyway? The first place I experienced it was AmigaOS 2.0. NeXTStep had reusable controls but AFAIK it didn't provide formats to all installed applications.

The problem with fusion is that until someone demonstrates a practical way to sustain it and produce energy, it's probably not going to get the kind of funding needed to demonstrate a practical way to sustain it and produce energy. At least not in less than several decades, and we don't have that long.

Like fossil fuels and nuclear, it is competing for funding with renewables. Renewables are mature, are cheap, and the market is growing. Because we are all capitalist societies, that's the only way we can address climate change.

I'd love to see fusion reactors in my lifetime, but nobody has a path to them that isn't full of huge challenges and unknowns.

It's not necessarily dangerous. We can start small, and anything you put up to block the sun is going to be pushed away from it by the pressure of the photons, or you can stick it in a decaying orbit so it has a limited lifespan.

As long as it is designed to have a limited lifespan and clear itself out naturally, like the tens of thousands of LEO satellites we are throwing up now without much care, the damage that can be done is negligible. Once proven safe we can look at scaling it up, in a way that means if we stop replenishing it, it just goes away by itself after a while.

The cost of electricity in the UK is dictated by gas prices, and despite having our own North Sea gas we pay the international market rate. That went up when Putin started his war in Ukraine. The faster we get off gas, the sooner the bills can come down.

Before then we really need to break the link between gas prices and electricity prices. Currently the way the auction works, everyone gets paid the amount offered to gas generators (nuclear has a special deal that is insanely expensive but doesn't set a price floor).

The whole point of the label "Dark Energy" is it's a filler for an unknown that still needs to be explained.

The whole point of dark energy is to explain why the cosmos is expanding more than it theoretically should be. If it isn't, then you don't need dark energy, or if it isn't expanding as much as formerly believed then you don't need as much of it.

yes, actually yes. I would do it differently though, I would use sodium and burn it in water to create the particulate matter, this would accomplish more than one goal, it would block a percentage point of the Solar energy and would percipitate into the ocean water deacidifying it. If done xorrectly, maybe as NaK alloy it can also be used to generate power while burning in water.
