We're a lot better at making tunnels now, and that particular monstrosity seems to have been plagued by construction errors made by contractors.

Nobody would have dreamed a hundred years ago that the channel tunnel was possible, let alone safe (if indeed, it is).

they wont work on a cargo ship lol

Yeah, I know. I've read about electric power supplementation beinginstalled on modern cargo ships. If they ever deliver on fusion... everything will change.

And if they used Roman concrete, it'd get all get stronger with age - they can use normal ash, no need for volcanic:

but you will still have to pay for it

Once there are fusion power stations, electricity production would be dirt cheap - but I bet British Gas will still find a way to stack my bill...

While they work on fusion, they could use far cleaner Thorium reactors, which can't be weaponised:

Everything would be better if I was crowned King of The World, obviously

That's a mad battery.

I want a suitcase-sized Thorium reactor for my home, to be replaced with a fusion reactor at a much later date.

While we're waiting for this mythical long mooted-always-10-years-away breakthrough in fusion to manifest, there's is enough energy in the earth's core to power humity for millions of years:

Boston's was a brave try at separating traffic from people's lives though, traffic below and parks and pavements above. Before its time of course and made more difficult in a country which worships cars as gods.

Whoever wrote that Wikipedia article just enjoyed putting the boot in while scarcely understanding the good intentions.

Yes, hiding cars underground rather goes against the grain. We'll see (we'll be dead of course by then) such infrastructure made under the lunar surface:

Lidar-equipped spherical probes or solar panel-powered cranes, perhaps?

"Slow boat to China" ? Of course it could be done, but commerce can't wait. As supplemetary propulsion perhaps.

It's entirely practical as supplementary power when available, but the industry is only interested if it makes money.

That of course isn't the point, it's value is in cutting the filthy emissions of shipping to help conquer climate change. International legislation is the answer, "Ve haf vays of making you understand!"

Not just wind of course, the immense surface area of oil tankers and bulk carriers covered with solar panels as they mostly sail close to the equator could produce loads of propulsion power, subject to electrical safety measures of course.

Are you advocating a Greta-led deep green fascist world? It can't work. We don't have to ditch technological progress and capitalism, but it'd cost 15 trillion to reverse global warming - cheap compared to the 16 trillion spent on the Covid-19 response so far.

I reckon it may cost a great deal more than that.
It may take a couple of generations too.
I watched the video in your post #68 late last night.
The effort to tear down a Tesla battery! That would put off large scale recycling.
We'll have to refine our battery technology a lot more before we could even consider reversing global warming possible.
